Letter from the President

Dear Shareholder:

We are pleased to provide you with the Touchstone Strategic Trust Annual Report. Inside you will find key financial information, as well as manager commentaries for the Funds, for the 12 months ended December 31, 2017.

Nearly ten years after the 2008 Credit Crisis, the economic recovery finally seemed to have taken hold in calendar year 2017. Economists and market strategists trumpeted the start of a “synchronized global expansion” as economic growth in the U.S., Japan, Europe and China aligned to provide a powerful impetus for a broader acceleration in global growth. While economic strength was synchronized across the world, monetary policies experienced further divergence. The Bank of Japan and the European Central Bank maintained accommodative stances, providing ample stimulus in an effort to sustain recent positive growth trends in gross domestic product after years of economic fragility. Meanwhile, with solid growth entrenched in the U.S., the U.S. Federal Reserve Board (Fed) continued moving toward its goal of monetary policy normalization by raising rates in March, June and December and announcing plans to reduce the size of its balance sheet.

Global equities posted strong double-digit returns across most broad U.S. and non-U.S. equity indexes. Growth-oriented stocks led U.S. equity markets over their value-oriented counterparts, while large capitalization stocks outperformed small-and mid-capitalization stocks. Outside the U.S., emerging market equities generated very strong returns followed closely by developed market equities.

While the Fed’s three rate hikes during the year pushed short-term rates higher, longer-term rates remained mostly range bound. This stable interest rate environment for intermediate to long-term interest rates allowed investment grade corporate bonds to generate solid returns. Non-investment grade bonds benefitted from the low default environment and stronger economic growth to lead the fixed income market.

The new year provides a natural point to assess the recent past and to look toward the future. From a financial perspective, it has been yet another period of strong returns across many asset classes. This makes it a particularly timely juncture to assess your current financial situation and, with the help of your financial advisor, re-assess your plans for the year – and years ahead.

We greatly appreciate your continued support. Thank you for including Touchstone as part of your investment plan.

Sincerely,

Jill T. McGruder

President

Management's Discussion of Fund Performance (Unaudited)

Touchstone Dynamic Equity Fund

Sub-Advised by Analytic Investors, LLC

Investment Philosophy

The Fund seeks long-term capital appreciation from hedged equity investments with less risk than a fully invested, unhedged equity portfolio. A proprietary system that ranks stocks according to a quantitative model is utilized in an attempt to create a diversified and hedged portfolio, which invests in a combination of long and short stocks and options, including covered calls. A security’s intrinsic value is determined by evaluating variables such as relative valuation, price momentum, company fundamentals, liquidity and risk.

Fund Performance

The Touchstone Dynamic Equity Fund (Class A Shares) underperformed its first benchmark, the S&P 500^® Index, and outperformed its second benchmark, the Citigroup 3-Month T-Bill Index, for the 12-month period ended December 31, 2017. The Fund’s total return was 7.18 percent (calculated excluding the maximum sales charge), while the total return of the first benchmark was 21.83 percent, and the total return of its second benchmark was 0.84 percent.

Market Environment

U.S. equities moved higher throughout the 12-month period despite a changing political landscape in Washington, D.C., and increasing geopolitical risk. For example, there were escalating tensions between the U.S. and North Korea, including the launch of North Korean ballistic missiles over Japan. In addition, the U.S. Federal Reserve Board (Fed) raised the federal funds rate three times during 2017, while in total it has raised interest rates only five times since the 2008 financial crisis. The market tended to shrug off the impact of the interest rate hikes during the year as they were widely expected by investors and seen as a sign that the economy was strong enough to support rising interest rates.

Economic news released during the year was mostly positive. For example, consumer confidence in March topped economic forecasts and soared to historically high levels. Consumer confidence also increased following the election of President Donald Trump amid the prospect of lower taxes and additional infrastructure spending. In addition, the U.S. economy grew faster than initially expected, which appeared to be driven by robust business spending on equipment and an accumulation of inventories. Healthy stock market gains, with low volatility, also seemed to be driven by corporations delivering solid earnings growth with little sign of near-term recession risk. Furthermore, the U.S. tax reform bill became a reality during the fourth quarter and the U.S unemployment rate remained at historically low levels.

Portfolio Review

The Fund is a hedged equity fund with a portfolio comprised of equities and options. During the year, the equity component of the Fund posted positive returns but underperformed the S&P 500^® Index. The call options component of the Fund posted negative returns as equities moved higher, while modestly outperforming the passive option component of the CBOE S&P 500 Buy Write Index, also known as the BXM Index (a benchmark index designed to track the performance of a hypothetical buy-write covered call strategy on the S&P 500^® Index).

The equity portion of the Fund is structured to be sector-, style- and beta¹-neutral relative to the S&P 500^® Index, thus trying to deliver outperformance through stock selection. Overall stock selection detracted from performance during the 12-month period, which was led by negative results within the Energy and Information Technology sectors.

Management's Discussion of Fund Performance (Unaudited) (Continued)

The Fund’s equity investment process uses a multi-characteristic approach when valuing securities. During the year, an emphasis on valuation characteristics was the primary driver of underperformance. Specifically, the Fund was overweight companies with above-average cash flow, earnings and dividends relative to their price. This detracted from Fund performance as investors avoided these qualities when selecting securities.

Among the individual stocks that contributed to relative performance during the calendar year were short positions in Symantec Corp. (Information Technology sector), Intercept Pharmaceuticals Inc. and Envision Healthcare Corp. (both from the Health Care sector), and long positions in Adobe Systems Inc., Texas Instruments Inc. (both from the Information Technology sector) and Amazon.com Inc. (Consumer Discretionary sector). Symantec is a software company providing security products and solutions to protect businesses from malware and other cyberattacks. The stock moved lower after Symantec softened its expected earnings guidance and reported profits that were lower than estimated. Intercept Pharmaceuticals is a biopharmaceutical company with a focus on therapeutics to treat liver disease. The stock dropped to historic lows after analysts cut the company’s price target following reports of patient deaths and a warning from the U.S. Food and Drug Administration (FDA). Envision Healthcare is a provider of healthcare services with a focus on physician services, medical transportation and ambulatory services. The stock moved lower due to concerns surrounding the impact of Hurricane Irma, the U.S. Senate’s renewed attempt to repeal the Affordable Care Act and the company’s failure to provide a business forecast update in recent press releases. During the fourth quarter, shares of the company fell by more than a third following a disappointing profit forecast. Adobe Systems is a software company providing digital marketing and document management solutions. The stock advanced to a record high after the company announced a bullish 2018 forecast and analysts reacted positively to Adobe’s new product road map. Furthermore, Adobe beat analyst estimates for sales and net income which provided evidence that the company’s switch to a cloud-based subscription model was paying off. Texas Instruments, a semiconductor manufacturer, moved markedly higher after the company increased its dividend and share repurchase program. Amazon, an online retailer of consumer products and subscriptions, moved higher after the company announced plans to acquire Whole Foods Market Inc.

Among the stocks that detracted from Fund performance were long positions in Merck & Co., Celgene Corp. (both from the Health Care sector), PG&E Corp. (Utilities sector) and Ulta Beauty Inc. (Consumer Discretionary sector), and a short position in Alnylam Pharmaceuticals (Health Care sector). Merck, a pharmaceutical company, declined meaningfully after the company reported sales that were lower than estimated and the stock was downgraded by a Morgan Stanley analyst. Celgene, a biopharmaceutical company with a focus on medicines for cancer and inflammatory disorders, posted one of its worst quarters in history during the year after the company lowered forecasts for current and future sales as well as its earnings-per-share (EPS). PG&E, a California-based natural gas and electric energy company, moved lower early in the fourth quarter following growing concerns that the company may be responsible for the wildfires in Northern California. Later in the quarter, the stock declined further after the company suspended its quarterly dividend, referencing uncertainty related to causes and potential liabilities associated with the wildfires. Ulta Beauty, a retailer of beauty products, moved meaningfully lower during the second quarter after same-store sales missed analyst expectations causing investor concerns over a slowing beauty category and increased competition. Alnylam Pharmaceuticals is a biopharmaceutical company focused on RNAi (a biological process in which RNA molecules inhibit gene expression or translation, by neutralizing targeted mRNA molecules) interference therapeutics. The company’s stock rallied after a competitor, Ionis Pharmaceuticals Inc., reported a patient death during a study for a drug that Alnylam is also trying to advance through trials. As a result, Credit Suisse boosted the company’s price target which also benefited the stock.

Management's Discussion of Fund Performance (Unaudited) (Continued)

Outlook

The Fund’s process is based on the fundamental belief that there is persistency in the types of characteristics investors prefer. If this holds going forward, we expect the Fund to benefit from being properly positioned toward stocks believed to have characteristics favored by investors. We continue to emphasize stocks with certain attractive valuation characteristics, such as stocks with below-average price-to-cash flow ratios and price-to-earnings ratios. In addition, we will continue to focus on companies with strong quality metrics, such as stocks with favorable return on equity and return on assets. Finally, we will seek to continue to deemphasize risk as investors avoid companies with above-average risk characteristics, such as above-average leverage.

Equity Fund - Class A*, the S&P 500^® Index and the Citigroup 3-Month T-Bill Index

The chart above represents performance of Class A shares only, which will vary from the performance of Class C shares, Class Y shares and Institutional Class shares based on the differences in sales loads and fees paid by shareholders in the different classes. The inception date of Class A shares, Class C shares, Class Y shares and Institutional Class shares was March 31, 2005, March 31, 2005, July 1, 1978 and December 9, 2005, respectively. Class A shares, Class C shares and Institutional Class shares performance information was calculated using the historical performance of Class Y shares for periods prior to March 31, 2005, March 31, 2005 and December 9, 2005, respectively. The returns have been restated for sales loads and fees applicable to Class A, Class C and Institutional Class shares. The returns of the indexes listed above are based on the inception date of the Fund.

The average annual total returns shown above are adjusted for maximum sales loads and fees, if applicable. The maximum offering price per share of Class A shares is equal to the net asset value (“NAV”) per share plus a sales load equal to 6.10% of the NAV (or 5.75% of the offering price). Class C shares are subject to a contingent deferred sales charge (“CDSC”) of 1.00%. The CDSC will be assessed on an amount equal to the lesser of (1) the NAV at the time of purchase of the shares being redeemed or (2) the NAV of such shares being redeemed, if redeemed within a one-year period from the date of purchase. Class Y shares and Institutional Class shares are not subject to sales charges.

The performance of the above Fund does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

Management's Discussion of Fund Performance (Unaudited)

Touchstone Controlled Growth with Income Fund

Sub-Advised by Wilshire Associates Incorporated

Investment Philosophy

The Fund is a “fund-of-funds,” which seeks to achieve its investment goal of providing investors with growth and income by investing primarily in a diversified portfolio of underlying equity, fixed-income and alternative funds (although a portion of its assets may be invested in cash, cash equivalents, or in money market funds). These underlying funds, in turn, invest in a variety of U.S. and foreign equity securities, fixed-income instruments and other investments. The Fund will allocate a significant portion of its assets to underlying funds utilizing alternative or nontraditional investment strategies, such as long-short, merger arbitrage, flexible income and credit opportunities strategies. The majority of the underlying funds in which the Fund invests will be affiliated funds; however, the Fund has the ability to invest in unaffiliated underlying funds, including exchange-traded funds (ETFs) and exchange-traded notes (ETNs), to the extent that the desired asset class exposure is not available through Touchstone Funds.

Fund Performance

The Touchstone Controlled Growth with Income Fund (Class A Shares) outperformed both of its benchmarks, the ICE BofA Merrill Lynch 3-Month U.S. Treasury Bill Index and the Wilshire Liquid Alternative Index for the 12-month period ended December 31, 2017. The Fund’s total return was 5.23 percent (calculated excluding the maximum sales charge) while the total return of the ICE BofA Merrill Lynch 3-Month U.S. Treasury Bill Index was 0.86 percent and the total return for the Wilshire Liquid Alternative Index was 5.08 percent for the same period.

Market Environment

The U.S. stock market rose in 2017. Nine of the eleven major sectors produced positive gains, with only Energy and Telecommunications Services ending the year with negative returns. The best performing sectors were Information Technology, Materials and Health Care. Large capitalization stocks outperformed small-caps. Growth stocks led value during the year in both large- and small capitalization spaces.

Equity markets outside of the U.S. produced strong returns during 2017, in both developed and emerging markets. The U.S. dollar continued to weaken, providing an additional boost for U.S. investors holding foreign currencies. With economic data out of Europe improving, European equities provided strong returns in the second and third quarters of 2017. Japan was one of the strongest developed markets during the fourth quarter due to stimulative policies by both the Bank of Japan and the national government. Japan is now experiencing its strongest economy in more than a decade. Emerging markets led all global equities during 2017, which was the strongest year for broad emerging markets equity since it recovered from the global financial crisis in 2009.

The U.S. Treasury yield curve continued to flatten during the year with short-to intermediate-term rates rising and long-term yields falling. The bellwether 10-year Treasury yield ended the year up slightly from year-end 2016. The Federal Open Market Committee increased its overnight rate three times in 2017, a total increase of 75 basis points, and began its balance sheet reduction program. Credit spreads continued to tighten during the year, most noticeably with investment grade credit.

Real estate securities were up in the U.S. during the year with a stronger return globally, due in part to a weakening dollar. Commodities were mixed for the year, as crude oil and gold prices rose while natural gas prices and master limited partnership returns were down.

Management's Discussion of Fund Performance (Unaudited) (Continued)

Portfolio Review

During the year, none of the Fund’s underlying allocations generated a loss. Compared to the beginning of 2017, the allocation to government fixed income was increased at the expense of investment grade and high yield credit. This change was made in conjunction with our shift back to neutral (from overweight) fixed income relative to equities. We added government fixed income exposure to essentially off-set the higher equity risk in the Fund’s portfolio. Overall, the Fund remains somewhat conservatively positioned relative to long-term targets, delivering income while also participating in equity markets.

Although the Fund was positioned conservatively early in the year, its exposure to long only and hedged equities was beneficial. Touchstone Dynamic Equity Fund was the top contributor to the Fund’s return. Overall, the Fund’s long only equity allocation also generated strong return contribution driven by the Fund’s allocations to Touchstone Focused Fund and Touchstone Premium Yield Equity Fund. Within the fixed income portion of the Fund’s portfolio, Touchstone Flexible Income Fund recorded strong results, and was among the top contributors to the Fund’s overall return. The Fund’s weakest performer was Touchstone Arbitrage Fund, which had the largest average portfolio weight during the year and ultimately represented a modest drag on the Fund’s overall return.

Outlook

Although global equities are not cheap, we believe that there is little risk of a recession in the near term across most of the world’s major economies. Although the Fund remains positioned somewhat conservatively relative to long-term allocation targets, it continues to be invested in risk assets. We have pared back the Fund’s credit risk in recent quarters in exchange for moving to a target weight to long only equities. We continue to expect a moderating economic growth environment in the foreseeable future, and to believe that the current economic landscape warrants lower interest rates and lower expected returns across asset classes.

Developed markets remain relatively stable in terms of gross domestic product (GDP) growth on a normalized basis, and we are still seeing below average growth in emerging markets, albeit at a faster pace than in developed markets. On a forward looking basis, when we look at the Purchasing Managers Index, which is an indicator of economic health in the manufacturing sector of a country or a region, we continue to witness positive economic momentum in the foreign economies of both the Eurozone and Japan relative to the U.S. On a global basis, measures of inflation are mostly in-line with or slightly below historic averages. Given that global growth and inflation remain moderate, we believe that global central banks will be slower to tighten monetary policy relative to market expectations. Given ultra-low foreign developed market bond yields, we favor domestic fixed income over global fixed income. However, we recognize that further weakness in the U.S. dollar would serve to benefit foreign fixed income.

Although we believe domestic equities are fully valued, we also believe that the outlook for continued domestic and foreign GDP growth is encouraging, and that equities are not poised for an imminent selloff. Given elevated forward price-earnings levels, any disappointment in U.S. corporate earnings growth is likely to be interpreted negatively. Investors have noted concerns that the U.S. Federal Reserve Board’s (Fed) decision to gradually shrink its balance sheet introduces additional risk to U.S. Treasury bonds, as this reduction in demand and increase in supply may introduce the additional risk of a significant rise in yields. While we acknowledge this risk, we believe that it is important to recognize the recent recovery in foreign demand for U.S. Treasury bonds following the net selling activity in 2016. The Fed may be stepping away, but foreign buyers have returned. With respect to credit markets, given the further narrowing of corporate bond yield spreads over Treasuries, we remain less favorable on credit and are still underweight credit and overweight government bonds.

We believe the Fund continues to be well positioned for the current investment environment. The majority of the Fund’s investments are to managers that employ defensive or hedged equity or credit trading strategies.

Management's Discussion of Fund Performance (Unaudited) (Continued)

There is also some modest, consistent long-only equity beta¹ that should allow the Fund to modestly participate in a continued domestic equity market rally. Overall, the Fund is positioned somewhat conservatively, relative to our long-term strategic allocation targets.

Touchstone Dynamic Diversified Income Fund

Sub-Advised by Wilshire Associates Incorporated

Investment Philosophy

The Fund is a “fund-of-funds,” which seeks to achieve its investment goal of providing investors with current income by investing primarily in a diversified portfolio of fixed-income and equity-income oriented underlying funds (although a portion of its assets may be invested in cash, cash equivalents, or in money market funds). The majority of the underlying funds in which the Fund invests will be affiliated funds; however, the Fund has the ability to invest in unaffiliated underlying funds, including exchange-traded funds (ETFs) and exchange-traded notes (ETNs), to the extent that the desired asset class exposure is not available through Touchstone Funds.

Fund Performance

The Touchstone Dynamic Diversified Income Fund (Class A Shares) outperformed its first benchmark, the Bloomberg Barclays U.S. Aggregate Bond Index, and underperformed its second benchmark, the MSCI All Country World Index, for the 12-month period ended December 31, 2017. The Fund’s total return was 7.74 percent (calculated excluding the maximum sales charge) while the total return of the Bloomberg Barclays U.S. Aggregate Bond Index was 3.54 percent and the total return of the MSCI All Country World Index was 23.97 percent.

Market Environment

Equity markets outside of the U.S. produced strong returns during 2017, in both developed and emerging markets. The U.S. dollar continued to weaken, providing an additional boost for U.S. investors holding foreign currencies. With economic data out of Europe improving, European equities provided strong returns in the second and third quarters of 2017, while Japan was one of the strongest developed markets during the fourth quarter due to stimulative policies by both the Bank of Japan and the national government. Japan is now experiencing its strongest economy in more than a decade. Emerging markets led all global equities during 2017, which was the strongest year for broad emerging markets equity since it recovered from the global financial crisis in 2009.

The U.S. Treasury yield curve continued to flatten during the year with short- to intermediate-term rates rising and long-term yields falling. The bellwether 10-year Treasury yield ended the year up slightly from year-end 2016. The Federal Open Market Committee increased its overnight rate three times in 2017, a total increase of 75 basis points, and began its balance sheet reduction program. Credit spreads continued to tighten during the year, most noticeably with investment grade credit.

Portfolio Review

Compared to the beginning of 2017, several allocation changes occurred. Most notably, the allocation to government fixed income was increased at the expense of investment grade and high yield credit. This change was made

Management's Discussion of Fund Performance (Unaudited) (Continued)

Exposure to international developed and emerging market equities and fixed income was increased during the year due to our growing confidence in the ability of foreign capital markets to outperform U.S. capital markets. Every major global economy is growing and the fundamentals have improved rapidly in many regions. Coupled with the potential for U.S. dollar weakening and rapid corporate earnings growth, we believe that foreign equities will continue their recent outperformance versus domestic equities.

The Fund’s permanent bias toward equity income represented a performance headwind in 2017, as non-dividend or low dividend yielding equities far outpaced higher dividend payers across broad equity indices. The Fund’s top equity allocations included the Touchstone Premium Yield Equity Fund and Touchstone Value Fund, which both generated positive returns for the year but lagged broader equity indices. Yet within the Fund’s fixed income allocation, exposure to high yield credit contributed to overall performance despite the aforementioned decision to reduce the overall weight to high yield bonds. Reflective of the strong credit market performance, Touchstone Credit Opportunities Fund was the largest contributor to the overall Fund return. There was only one allocation that detracted from returns during the year, JPMorgan Alerian MLP ETN.

Outlook

Although global equities are not cheap, we believe that there is little risk of a recession in the near term across most of the world’s major economies. Even though the Fund remains positioned somewhat conservatively relative to long-term allocation targets, it continues to be invested in risk assets. We have pared back the Fund’s credit risk in recent quarters in exchange for moving to a target weight to long only equities. We continue to expect a moderating economic growth environment in the foreseeable future, and therefore we continue to believe that the current economic landscape warrants lower interest rates and lower expected returns across asset classes.

Management's Discussion of Fund Performance (Unaudited) (Continued)

We believe the Fund continues to be well-positioned for the current investment environment. We believe the income orientation of the Fund helps to cushion volatility. We do not believe that domestic equity markets are likely to continue to experience a strong rally, so the equity income orientation of the Fund currently serves it well. Overall, the Fund is positioned somewhat conservatively, relative to our long-term strategic allocation targets.

Under normal circumstances, the Fund (through its investment in underlying funds) will invest at least 40% of its portfolio in securities of issuers outside of the U.S.

Fund Performance

The Touchstone Dynamic Global Allocation Fund (Class A Shares) underperformed its first benchmark, the MSCI All Country World Index, and outperformed its second benchmark, the Bloomberg Barclays Global Aggregate Index, for the 12-month period ended December 31, 2017. The Fund’s total return was 13.96 percent (calculated excluding the maximum sales charge) while the total return of the MSCI All Country World Index was 23.97 percent and the total return of the Bloomberg Barclays Global Aggregate Index was 7.39 percent.

Market Environment

The U.S. Treasury yield curve continued to flatten during the year with short- to intermediate-term rates rising and long-term yields falling.

Credit spreads continued to tighten during the year, most noticeably with investment grade credit.

Portfolio Review

Management's Discussion of Fund Performance (Unaudited) (Continued)

in conjunction with our shift back to neutral (from overweight) fixed income relative to equities. By adding government fixed income exposure, we added a partial hedge to off-set the increase in equity risk we were adding back to the portfolio. During mid-2017, exposure was initiated to Touchstone Ultra Short Duration Fixed Income Fund in order to reduce interest rate risk within the Fund, out of concern that a “neutral” duration posture relative to the Bloomberg Barclays U.S. Aggregate Bond Index was adding materially more interest rate risk than is typical due to the increased duration of the index in recent years.

The Fund’s overweight to the domestic value style within the equity allocation was removed during the year. We no longer felt that valuations justified an overt overweight to value equities. Exposures to international developed and emerging market equities were increased during the year due to our increased confidence in the ability of foreign equities to outperform U.S. equities. Every major global economy is growing and the fundamentals have improved rapidly in many regions. Coupled with the potential for U.S. dollar weakening and rapid corporate earnings growth, we believe that foreign equities will continue their recent outperformance versus domestic equities.

The Fund’s performance was hindered by its modestly conservative positioning throughout 2017. The equity allocation slightly underperformed the MSCI All Country World Index, as the aforementioned value style bias early in the year represented a performance headwind. On a stand-alone basis, the Fund’s fixed income allocation underperformed the Bloomberg Barclays Global Aggregate Index, due to the allocation’s domestic investment grade fixed income and U.S. dollar exposure. Developed market non-U.S. investment grade bonds outperformed their U.S. counterparts and the U.S. dollar weakened relative to most major currencies, contributing to the underperformance of the Fund’s fixed income allocation relative to the Bloomberg Barclays Global Aggregate Index.

The Fund’s allocation to the Touchstone Sands Capital Emerging Markets Growth Fund and Touchstone Sands Capital Institutional Growth Fund were the two strongest performing allocations on a stand-alone basis during the year. In terms of contribution to return, the most notable allocations were to Touchstone International Value Fund and Touchstone International Growth Fund, as non-U.S. equities generally had a strong year due to improved global economic and market conditions, as well as a weakening U.S. dollar.

Outlook

Although global equities are not cheap, we believe that there is little risk of a recession in the near term across most of the world’s major economies. Although the Fund remains positioned somewhat conservatively relative to long-term allocation targets, it continues to be invested in risk assets. We have pared back the Fund’s credit risk in recent quarters in exchange for moving to a target weight to long only equities. We continue to expect a moderating economic growth environment in the foreseeable future, and therefore we continue to believe that the current economic landscape warrants lower interest rates and lower expected returns across asset classes.

Management's Discussion of Fund Performance (Unaudited) (Continued)

We believe the Fund continues to be well-positioned for the current investment environment. We continue to favor foreign equities versus domestic equities, but believe that valuations across most asset classes are somewhat rich. Within fixed income, the Fund has sought to decrease interest rate risk while also increasing the credit quality of the portfolio. Overall, we continue to believe that the Fund is best served by remaining invested in risk assets, but we have sought to improve the portfolio risk profile where appropriate. Overall, the Fund is positioned somewhat conservatively, relative to our long-term strategic allocation targets.

Management's Discussion of Fund Performance (Unaudited) (Continued)

1. Organization

The Touchstone Strategic Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Massachusetts business trust pursuant to an Agreement and Declaration of Trust dated November 18, 1982. The Trust consists of twenty-five funds, including the following four funds (individually, a “Fund”, and collectively, the “Funds”):

Touchstone Dynamic Equity Fund (“Dynamic Equity Fund”)

Touchstone Controlled Growth with Income Fund (“Controlled Growth with Income Fund”)

Touchstone Dynamic Diversified Income Fund (“Dynamic Diversified Income Fund”)

Touchstone Dynamic Global Allocation Fund (“Dynamic Global Allocation Fund”)

Each Fund is diversified. Additionally, the Controlled Growth with Income Fund, Dynamic Diversified Income Fund and Dynamic Global Allocation Fund (collectively, the “Allocation Funds”) are “Funds of Funds”, sub-advised by Wilshire Associates Incorporated, which seek to achieve their investment goals by primarily investing in a diversified portfolio of affiliated and unaffiliated underlying equity, fixed income and alternative funds. These underlying funds (“Underlying Funds”), in turn, invest in a variety of U.S. and foreign equity and fixed income securities. Under normal circumstances, the Allocation Funds expect to invest their assets among equity, fixed-income and alternative funds in the following ranges:

	Equity Fund	Fixed-Income	Alternative
	Allocation	Fund Allocation	Fund Allocation
Controlled Growth with Income Fund	0-25%	25-50%	50-75%
Dynamic Diversified Income Fund	25-55%	25-55%	0-30%
Dynamic Global Allocation Fund	45-75%	25-55%	N/A

The investment goal of each of the Underlying Funds that the Allocation Funds invested in is as follows:

Fund		Investment Goal
Touchstone Arbitrage Fund		Seeks to achieve positive absolute returns over the long-term regardless of market conditions.
Touchstone Credit Opportunities Fund		Seeks absolute total return, primarily from income and capital appreciation.
Touchstone Dynamic Equity Fund		Seeks to obtain long-term capital appreciation from hedged equity investments with less risk than a fully invested, unhedged equity portfolio.
Touchstone Flexible Income Fund		Seeks a high level of income consistent with reasonable risk. The Fund seeks capital appreciation as a secondary goal.
Touchstone Focused Fund		Seeks capital appreciation.
Touchstone Growth Opportunities Fund		Seeks long-term growth of capital.
Touchstone High Yield Fund		Seeks to achieve a high level of income as its main goal. Capital appreciation is a secondary consideration.

Vanguard Total International Bond ETF		Seeks to track the performance of a benchmark index that measures the investment return of investment-grade bonds issued outside of the United States.
WisdomTree Emerging Markets High Dividend ETF		Seeks to track the investment results of high-dividend-yielding companies in the emerging markets region.

The Agreement and Declaration of Trust permits the Trust to issue an unlimited number of shares of beneficial interest of each Fund. The Dynamic Equity Fund is registered to offer the following classes of shares: Class A shares, Class C shares, Class Y shares, and Institutional Class shares. The Allocation Funds are registered to offer the following classes of shares: Class A shares, Class C shares and Class Y shares. The assets of each Fund are segregated, and a shareholder’s interest is limited to the Fund in which shares are held. The Funds’ prospectus provides a description of each Fund’s investment goal, policies, and strategies along with information on the classes of shares currently being offered.

2. Significant Accounting Policies

The following is a summary of the Funds’ significant accounting policies:

Each Fund is an investment company that follows the accounting and reporting guidance of Accounting Standards Codification Topic 946 applicable to investment companies.

Security valuation and fair value measurements — U.S. generally accepted accounting principles (“U.S. GAAP”) define fair value as the price the Funds would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. All investments in securities are recorded at their fair value. The Funds define the term “market value”, as used throughout this report, as the estimated fair value. The Funds use various methods to measure fair value of their portfolio securities on a recurring basis. U.S. GAAP fair value measurement standards require disclosure of a hierarchy that prioritizes inputs to valuation methods.

These inputs are summarized in the three broad levels listed below:

·	Level 1 –	quoted prices in active markets for identical securities
·	Level 2 –	other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)
·	Level 3 –	significant unobservable inputs (including a Fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The aggregate value by input level, as of December 31, 2017, for each Fund’s investments, as well as a reconciliation of assets for which significant unobservable inputs (Level 3) were used in determining value, if applicable, is included in the Funds’ Portfolio of Investments, which also includes a breakdown of the Funds’ investments by sector allocation. The Funds did not hold any Level 3 categorized securities during the year ended December 31, 2017.

Changes in valuation techniques may result in transfers into or out of an investment’s assigned level within the hierarchy. All transfers in and out of the levels are recognized at the value at the end of the period. At December 31, 2017, there were no transfers between Levels 1, 2 and 3 for all Funds.

During the year ended December 31, 2017, there were no material changes to the valuation policies and techniques.

The Funds’ portfolio securities are valued as of the close of the regular session of trading on the New York Stock Exchange (“NYSE”)(currently 4:00 p.m., Eastern time). Portfolio securities traded on stock exchanges are valued at the last reported sale price, official close price, or last bid price if no sales are reported. Portfolio securities quoted by NASDAQ are valued at the NASDAQ Official Closing Price (“NOCP”) or from the primary exchange on which the security trades. To the extent these securities are actively traded, they are categorized in Level 1 of the fair value hierarchy. Options are valued at the last quoted sales price. If there is no such reported sale on the valuation date, long option positions are valued at the most recent bid price, and short option positions are valued at the most recent ask price on the valuation date and are categorized in Level 1. Shares of mutual funds in which the Funds invest are valued at their respective net asset values (“NAV”) as reported by the Underlying Funds and are categorized in Level 1.

Securities mainly traded on a non-U.S. exchange or denominated in foreign currencies are generally valued according to the preceding closing values on that exchange, translated to U.S. dollars using currency exchange rates as of the close of regular trading on the NYSE, and are generally categorized in Level 1. However, if an

Notes to Financial Statements (Continued)

event that may change the value of a security occurs after the time that the closing value on the non-U.S. exchange was determined, but before the close of regular trading on the NYSE, the security may be priced based on fair value and generally categorized in Level 2. This may cause the value of the security, if held on the books of a Fund, to be different from the closing value on the non-U.S. exchange and may affect the calculation of that Fund’s NAV.

The Funds may use fair value pricing under the following circumstances, among others:

If the value of a security has been materially affected by events occurring before the Funds’ pricing time but after the close of the primary markets on which the security is traded.

If the exchange on which a portfolio security is principally traded closes early or if trading in a particular portfolio security was halted during the day and did not resume prior to the Funds’ NAV calculation.

If a security is so thinly traded that reliable market quotations are unavailable due to infrequent trading.

If the validity of market quotations is not reliable.

Securities held by the Funds that do not have readily available market quotations, significant observable inputs, or securities for which the available market quotations are not reliable, are priced at their estimated fair value using procedures approved by the Funds’ Board of Trustees (the “Board”) and are generally categorized in Level 3.

Allocation Funds — The Allocation Funds invest in securities of affiliated and unaffiliated funds, the Underlying Funds. The value of an investment in the Allocation Funds is based on the performance of the Underlying Funds in which they invest and the allocation of their assets among those funds. Because the Allocation Funds invest in mutual funds, shareholders of the Allocation Funds indirectly bear a proportionate share of the expenses charged by the Underlying Funds in which they invest as well as their share of the Allocation Funds’ fees and expenses. The principal risks of an investment in the Allocation Funds include the principal risks of investing in the Underlying Funds.

Investment companies — The Funds may invest in securities of other investment companies, including exchange-traded funds (“ETFs”), exchange-traded notes (“ETNs”), open-end funds and closed-end funds. Open-end funds are investment companies that issue new shares continuously and redeem shares daily. Closed-end funds are investment companies that typically issue a fixed number of shares that trade on a securities exchange or over-the-counter (“OTC”). An ETF is an investment company that typically seeks to track the performance of an index by holding in its portfolio shares of all the companies, or a representative sample of the companies, that are components of a particular index. An ETN is an investment company that typically seeks to track the performance of an index, similar to an ETF, but it does not hold any securities that it tracks. ETF and ETN shares are traded on a securities exchange based on their market value. The risks of investment in other investment companies typically reflect the risks of the types of securities in which the other investment companies invest. Investments in ETFs, ETNs and closed-end funds are subject to the additional risk that their shares may trade at a premium or discount to their NAV. Investments in ETNs are also subject to credit risk similar to other debt securities. When a Fund invests in another investment company, shareholders of the Fund indirectly bear their proportionate share of the other investment company’s fees and expenses, including operating, registration, trustee, licensing, and marketing, as well as their share of the Fund’s fees and expenses.

Cash and cash equivalents — The Funds consider liquid assets deposited with a bank, money market funds, and certain short term debt instruments with maturities of 3 months or less to be cash equivalents and are included in the investments on the financial statements. These investments represent amounts held with financial institutions that are readily accessible to pay Fund expenses or investments. Cash and cash equivalents are valued

Notes to Financial Statements (Continued)

at cost plus accrued interest, which approximates market value. The value of cash equivalents denominated in foreign currencies is determined by converting to U.S. dollars on the date of the Statement of Assets and Liabilities.

Securities sold short — The Dynamic Equity Fund may engage in selling securities short, which obligates the Fund to replace a security borrowed by purchasing the same security at the current market value. The Fund would incur a loss if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security. The Fund would realize a gain if the price of the security declines between those dates. As of December 31, 2017, the Dynamic Equity Fund had securities sold short with a fair value of $(22,940,552) and pledged securities with a fair value of $135,729,484 as collateral for both securities sold short and written options and had a related due to prime broker balance of $1,936,681.

Options — The Dynamic Equity Fund may write or purchase financial option contracts primarily to hedge against changes in the value of equity securities (or securities that the Fund intends to purchase), against fluctuations in fair value caused by changes in prevailing market interest rates or foreign currency exchange rates and against changes in overall equity market volatility. In addition, the Fund may utilize options in an attempt to generate gains from option premiums or to reduce overall portfolio risk. The Fund’s option strategy primarily focuses on the use of writing and/or purchasing call or put options on equity indexes. When the Fund writes or purchases an option, an amount equal to the premium received or paid by the Fund is recorded as a liability or an asset and is subsequently adjusted to the current market value of the option written or purchased. Premiums received or paid from writing or purchasing options which expire unexercised are treated by the Fund on the expiration date as realized gains or losses. The difference between the premium and the amount paid or received on effecting a closing purchase or sale transaction, including brokerage commissions, is also treated as a realized gain or loss. If an option is exercised, the premium paid or received is added to the cost of the purchase or proceeds from the sale in determining whether the Fund has realized a gain or loss on investment transactions. The Fund, as writer of an option, may have no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. The Fund, as purchaser of an option, bears the risk that the counterparties to the option may not have the ability to meet the terms of the option contracts. There is minimal counterparty credit risk involved in entering into option contracts since they are exchange-traded instruments and the exchange’s clearinghouse, as counterparty to all exchange-traded options, guarantees the options against default. As of December 31, 2017, the Dynamic Equity Fund had written options with a fair value of $(1,680,526) and pledged securities with a fair value of $135,729,484 as collateral for both securities sold short and written options and had a related due to prime broker balance of $1,936,681.

Real Estate Investment Trusts — The Dynamic Equity Fund may invest in real estate investment trusts (“REITs”) that involve risks not associated with investing in stocks. Risks include declines in the value of real estate, general and economic conditions, changes in the value of the underlying property and defaults by borrowers. The value of assets in the real estate industry may go through cycles of relative underperformance and outperformance in comparison to equity securities markets in general. Dividend income is recorded using management’s estimate of the income included in distributions received from REIT investments. The actual amounts of income, return of capital and capital gains are only determined by each REIT after its fiscal year-end and may differ from the estimated amount. Estimates of income are adjusted in the Funds to the actual amounts when the amounts are determined.

Derivative instruments and hedging activities — The Dynamic Equity Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement” or “MNA”) or similar agreement with certain counterparties. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs OTC derivatives and foreign exchange contracts, and typically contains, among other things, collateral posting terms and master netting provisions in the event of a default or termination.

Notes to Financial Statements (Continued)

Under an ISDA Master Agreement, a party may, under certain circumstances, offset with the counterparty certain derivative financial instrument’s payables or receivables with collateral held or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting). These default events include bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset.

When entering into a derivative transaction, the Fund may be required to post and maintain collateral or margin (including both initial and maintenance margin). Collateral and margin requirements differ by type of derivative. Margin requirements are established by the broker or clearing house for exchange-traded and centrally cleared derivatives (financial futures contracts, options, and centrally cleared swaps). Brokers can ask for margining in excess of the clearing house’s minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives (foreign currency exchange contracts, options, and swaps). For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by the Fund and the counterparty. For financial reporting purposes, cash collateral that has been pledged to cover obligations of the Fund and cash collateral received from the counterparty, if any, are reported separately on the Statements of Assets and Liabilities as cash pledged as collateral and cash received as collateral, respectively. Non-cash collateral pledged by the Fund, if any, is noted in the Portfolio of Investments. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty non-performance.

Certain ISDA Master Agreements allow counterparties to OTC derivatives transactions to terminate derivative contracts prior to maturity in the event the Fund’s net assets decline by a stated percentage or the Fund fails to meet the terms of its ISDA Master Agreement, which would cause the Fund (counterparty) to accelerate payment of any net liability owed to the counterparty (Fund).

For financial reporting purposes, the Dynamic Equity Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statements of Assets and Liabilities.

As of December 31, 2017, the Dynamic Equity Fund’s assets and liabilities that were subject to a MNA on a gross basis were as follows:

	Assets		Liabilities
Derivative Financial Instruments:
Written Options	$	—	$	1,680,526

The following table presents the Dynamic Equity Fund’s liabilities net of amounts available for offset under a MNA and net of the related collateral pledged by the Fund as of December 31, 2017:

* The balance at each quarter end was zero.

Share valuation — The NAV per share of each class of shares of each Fund is calculated daily by dividing the total value of a Fund’s assets attributable to that class, less liabilities attributable to that class, by the number of outstanding shares of that class.

The maximum offering price per share of Class A shares of the Funds is equal to the NAV per share plus a sales load equal to 6.10% of the NAV (or 5.75% of the offering price). There is no sales load on purchases of $1 million or more of Class A shares. The maximum offering price per share of Classes C, Y, and Institutional Class shares of the Funds is equal to the NAV per share.

The redemption price per share of each class of shares of the Funds is generally equal to the NAV per share. However, Class A redemptions that were part of a no-load $1 million subscription may be subject to a contingent deferred sales charge (“CDSC”) of up to 1.00% if redeemed within a one-year period from the date of purchase. Additionally, purchases of Class C shares of the Funds are subject to a CDSC of 1.00%. The CDSC will be assessed on an amount equal to the lesser of (1) the NAV at the time of purchase of the shares being redeemed or (2) the NAV of such shares being redeemed, if redeemed within a one-year period from the date of purchase.

Investment income — Dividend income from securities is recognized on the ex-dividend date, net of foreign withholding taxes, if any, which are reduced by any amounts reclaimable by the Funds, where applicable. Interest income from securities is recorded on the basis of interest accrued, premium amortized and discount accreted.

Notes to Financial Statements (Continued)

Distributions to shareholders — Each Fund intends to distribute to its shareholders substantially all of its income and capital gains. The Dynamic Equity Fund declares and distributes net investment income, if any, annually as a dividend to shareholders. The Allocation Funds each declare and distribute net investment income, if any, quarterly as a dividend to shareholders. Each Fund makes distributions of capital gains, if any, at least annually, net of applicable capital loss carryforwards. Income distributions and capital gain distributions are determined in accordance with income tax regulations. Recognition of the Funds’ net investment income from investments in Underlying Funds is affected by the timing of dividend declarations by the Underlying Funds.

Allocations — Investment income earned, realized capital gains and losses, and unrealized appreciation and depreciation for a Fund are allocated daily to each class of shares based upon its proportionate share of total net assets of the Fund. Class-specific expenses are charged directly to the class incurring the expense. Common expenses, which are not attributable to a specific class, are allocated daily to each class of shares based upon their proportionate share of total net assets of the Fund. Expenses not directly billed to a Fund are allocated proportionally among all Funds in the Trust, and, if applicable, Touchstone Funds Group Trust, Touchstone Institutional Funds Trust and Touchstone Variable Series Trust (collectively with the Trust, “Touchstone Fund Complex”), daily in relation to net assets of each Fund or another reasonable measure.

Security transactions — Security transactions are reflected for financial reporting purposes as of the trade date. Realized gains and losses on sales of portfolio securities are calculated using the identified cost basis.

Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

3. Investment Transactions

Notes to Financial Statements (Continued)

compensation and out-of-pocket expenses relating to their services. The Funds accrued Trustee-related expenses of $61,000 for the year ended December 31, 2017.

MANAGEMENT & EXPENSE LIMITATION AGREEMENTS

The Advisor provides general investment supervisory services for the Funds under the terms of an advisory agreement (the “Advisory Agreement”). Under the Advisory Agreement, each Fund pays the Advisor a fee, which is computed and accrued daily and paid monthly, at an annual rate based on average daily net assets of each Fund as shown in the table below.

The maximum annual operating expense limit in any year with respect to the Funds is based on a percentage of the average daily net assets of the Funds. The Advisor has agreed to separately waive class-level expenses, advisory fees and administration fees, and to reimburse expenses in order to maintain the following expense limitations for the Funds:

										Institutional			Termination
Fund	Class A			Class C			Class Y			Class			Date
Dynamic Equity Fund		1.55	%		2.30	%		1.30	%		1.25	%	April 30, 2018

Dynamic Global Allocation Fund		114,081		170,003		223,598		507,682

Under the terms of the Expense Limitation Agreement, the Advisor is entitled to recover, subject to approval by the Funds’ Board, such amounts waived or reimbursed for a period of up to three years from the date on which the Advisor reduced its compensation or assumed expenses for the Funds. No recoupment will occur unless a Fund’s operating expenses are below the expense limitation amount in effect at the time of the waiver or reimbursement and the Fund’s current expense limitation.

As of December 31, 2017, the Advisor may seek recoupment of previously waived fees and reimbursed expenses as follows:

	Expiration		Expiration		Expiration
	December 31,		December 31,		December 31,
Fund	2018		2019		2020		Total

The Advisor did not recoup any amounts it previously waived or reimbursed during the year ended December 31, 2017.

ADMINISTRATION AGREEMENT

The Advisor entered into an Administration Agreement with the Trust, whereby the Advisor is responsible for: supplying executive and regulatory compliance services; supervising the preparation of tax returns; coordinating the preparation of reports to shareholders and reports to, and filings with the Securities and Exchange Commission (the “SEC”) and state securities authorities, as well as materials for meetings of the Board; calculating the daily NAV per share; and maintaining the financial books and records of each Fund.

For its services, the Advisor’s annual administrative fee is:

0.145% on the first $20 billion of the aggregate average daily net assets;

0.11% on the next $10 billion of aggregate average daily net assets;

0.09% on the next $10 billion of aggregate average daily net assets; and

0.07% on the aggregate average daily net assets over $40 billion.

The fee is computed and allocated among the Touchstone Fund Complex (excluding Touchstone Institutional Funds Trust) on the basis of relative daily net assets.

The Advisor has engaged BNY Mellon as the Sub-Administrator to the Trust. BNY Mellon provides administrative and accounting services to the Trust and is compensated directly by the Advisor, not the Trust.

Notes to Financial Statements (Continued)

TRANSFER AGENT AGREEMENT

Under the terms of the Transfer Agent Agreement between the Trust and BNY Mellon, BNY Mellon maintains the records of each shareholder’s account, answers shareholders’ inquiries concerning their accounts, processes purchases and redemptions of each Fund’s shares, acts as dividend and distribution disbursing agent, and performs other shareholder service functions. For these services, BNY Mellon receives a monthly fee from each Fund. In addition, each Fund pays out-of-pocket expenses incurred by BNY Mellon, including, but not limited to, postage and supplies.

The Funds may reimburse the Advisor for fees paid to intermediaries such as banks, broker-dealers, financial advisors or other financial institutions for sub-transfer agency, sub-administration and other services provided to investors whose shares of record are held in omnibus, other group accounts, retirement plans or accounts traded through registered securities clearing agents. These fees may vary based on, for example, the nature of services provided, but generally range up to 0.15% of the assets of the class serviced or maintained by the intermediary or up to $22 per sub-account maintained by the intermediary.

PLANS OF DISTRIBUTION AND SHAREHOLDER SERVICING FEE ARRANGEMENTS

The Trust has adopted distribution plans pursuant to Rule 12b-1 under the 1940 Act for each class of shares it offers that is subject to 12b-1 distribution fees. The plans allow each Fund to pay distribution and other fees for the sale and distribution of its shares and for services provided to shareholders. The fees charged to the Funds are limited to the actual expenses incurred. Under the Class A plan, each Fund offering Class A shares pays an annual fee of up to 0.25% of average daily net assets that are attributable to Class A shares. Under the Class C plan, each Fund offering Class C shares pays an annual fee of up to 1.00% of average daily net assets that are attributable to Class C shares (of which up to 0.75% is a distribution fee and up to 0.25% is a shareholder servicing fee).

UNDERWRITING AGREEMENT

The Underwriter is the Funds’ principal underwriter and, as such, acts as exclusive agent for distribution of the Funds’ shares. Under the terms of the Underwriting Agreement between the Trust and the Underwriter, the Underwriter earned underwriting and broker commissions on the sale of Class A shares of the Funds.

5. Liquidity

Interfund lending — Pursuant to an Exemptive Order issued by the SEC on March 28, 2017, the Funds, along with certain other funds in the Touchstone Fund Complex, may participate in an interfund lending program. The interfund lending program provides an alternate credit facility that allows the Funds to lend to or borrow from other participating funds in the Touchstone Fund Complex, subject to the conditions of the Exemptive Order. The Funds may not borrow under the facility for leverage purposes and the loans’ duration may be no more than 7 days.

During the year ended December 31, 2017, the program was not utilized.

6. Federal Tax Information

Federal income tax — It is each Fund’s policy to continue to comply with the special provisions of the Internal Revenue Code applicable to regulated investment companies. As provided therein, in any fiscal year in which a Fund so qualifies and distributes at least 90% of its investment company taxable income, the Fund (but not the shareholders) will be relieved of federal income tax on the income distributed. It is each Fund’s policy to distribute all of its taxable income and accordingly, no provision for income taxes has been made.

Notes to Financial Statements (Continued)

In order to avoid imposition of the excise tax applicable to regulated investment companies, it is also each Fund’s intention to declare and pay as dividends in each calendar year at least 98% of its investment company taxable income (earned during the calendar year) and 98.2% of its net realized capital gains (earned during the twelve months ending October 31) plus undistributed amounts from prior years.

The tax character of distributions paid for the years ended December 31, 2017 and December 31, 2016 are as follows:

	Dynamic				Controlled Growth
	Equity Fund				with Income Fund
	Year Ended		Year Ended		Year Ended		Year Ended

Total distributions	$	1,974,623	$	2,523,053	$	5,204,079	$	7,815,212

The following information is computed on a tax basis for each item as of December 31, 2017:

	Dynamic			Controlled Growth
	Equity Fund			with Income Fund
Tax cost of portfolio investments	$	134,003,795		$	46,299,688

Accumulated earnings (deficit)	$	(3,858,840	)	$	4,542,507

The difference between the tax cost of portfolio investments and the financial statement cost is primarily due to wash sale loss deferrals, non-taxable transfer and a non-taxable distribution basis outstanding.

Notes to Financial Statements (Continued)

As of December 31, 2017, the Funds had the following capital loss carryforwards for federal income tax purposes:

	Short Term
	Expiring In
	2018*			Total
Dynamic Diversified Income Fund	$	4,801,366	**	$	4,801,366
Dynamic Global Allocation Fund		1,947,286	**		1,947,286

* The Regulated Investment Company Modernization Act of 2010 (the “Act”) was enacted on December 22, 2010. The Act made changes to several tax rules impacting the Funds. The provisions of the Act first became effective for the Funds’ fiscal year ended December 31, 2012 and are applicable to all subsequent fiscal years. Although the Act provides several benefits, including the unlimited carryover of future capital losses, there may be a greater likelihood that all or a portion of each Fund’s pre-enactment capital loss carryovers may expire without being utilized due to the fact that post-enactment capital losses must be utilized before pre-enactment capital loss carryovers may be utilized. Under the Act, new capital losses may now be carried forward indefinitely, and retain the character of the original loss as compared with pre-enactment law, where capital losses could be carried forward for up to eight years, and carried forward as short-term capital losses, irrespective of the character of the original loss.

**May be subject to limitation.

The capital loss carryforwards may be utilized in future years to offset net realized capital gains, if any, prior to distributing such gains to shareholders.

During the year ended December 31, 2017, the following Funds utilized capital loss carryforwards or had capital loss carryforwards expire:

Fund	Utilized		Expired
Dynamic Equity Fund	$	2,645,324	$	74,796,685
Dynamic Diversified Income Fund		1,701,562		6,348,257
Dynamic Global Allocation Fund		3,312,744		—

Under current laws, certain capital losses realized after October 31 and ordinary losses realized after December 31 may be deferred (and certain ordinary losses after October and/or December 31 may be deferred) and treated as occurring on the first day of the following fiscal year. For the year ended December 31, 2017, the Dynamic Equity Fund elected to defer $220,957 of realized capital losses.

The Funds have analyzed their tax positions taken on federal income tax returns for all open tax years (tax years ended December 31, 2014 through 2017) and have concluded that no provision for income tax is required in their financial statements.

Certain reclassifications, the result of permanent differences between financial statement and income tax reporting requirements, have been made to the components of capital. These reclassifications have no impact on the net assets or NAV per share of the Funds. The following reclassifications, which are primarily attributed to the reclassification of distributions received, reclassification of nontaxable and/or capital gain distributions, re-designation of dividends paid, expiration of prior year capital loss carryforwards and capitalized dividends on short sales have been made to the following Funds for the year ended December 31, 2017:

				Accumulated			Accumulated
	Paid-In			Net Investment			Net Realized
Fund	Capital			Income(Loss)			Gains(Losses)
Dynamic Equity Fund	$	(74,774,508	)	$	57,923		$	74,716,585
Controlled Growth with Income Fund		—			604,126			(604,126	)
Dynamic Diversified Income Fund		(6,348,257	)		(28,066	)		6,376,323
Dynamic Global Allocation Fund		(34,162	)		415,187			(381,025	)

7. Commitments and Contingencies

The Funds indemnify the Trust’s officers and Trustees for certain liabilities that might arise from their performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts that contain a variety of representations and warranties and which provide general indemnifications. The Funds’

Notes to Financial Statements (Continued)

maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Funds.

8. Principal Risks

Risks Associated with Credit — An issuer may be unable to make timely payments of either principal or interest. This may cause the issuer’s securities to decline in value. Credit risk is particularly relevant to those Funds that invest a significant amount of their assets in junk bonds or lower-rated securities.

Risks Associated with Interest Rate Changes — As interest rates rise, the value of fixed-income securities a Fund owns will likely decrease. The price of debt securities is generally linked to the prevailing market interest rates. In general, when interest rates rise, the price of debt securities falls, and when interest rates fall, the price of debt securities rises. The price volatility of a debt security also depends on its maturity. Longer-term securities are generally more volatile, so the longer the average maturity or duration of these securities, the greater their price risk. Duration is a measure of the expected life, taking into account any prepayment or call features of the security, that is used to determine the price sensitivity of the security for a given change in interest rates. Specifically, duration is the change in the value of a fixed-income security that will result from a 1% change in interest rates, and generally is stated in years. For example, as a general rule a 1% rise in interest rates means a 1% fall in value for every year of duration. Maturity, on the other hand, is the date on which a fixed-income security becomes due for payment of principal. The negative impact on fixed income securities if interest rates increase as a result could negatively impact a Fund’s NAV.

Risks Associated with Leverage — By investing the proceeds received from selling securities short, the Dynamic Equity Fund is employing leverage, which creates special risks. The use of leverage may increase the Fund’s exposure to long or short equity positions and may cause the Fund’s NAV to be more volatile than if the Fund had not used leverage. This could result in increased volatility of returns.

Please see the Funds’ prospectus for a complete discussion of these and other risks.

Subsequent events occurring after the date of this report have been evaluated for potential impact to this report through the date the financial statements were issued. There were no subsequent events that necessitated recognition or disclosure in the Funds’ financial statements.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of Touchstone Strategic Trust

Opinion on the Financial Statements

We have audited the accompanying statements of assets and liabilities of Touchstone Dynamic Equity Fund, Touchstone Controlled Growth with Income Fund, Touchstone Dynamic Diversified Income Fund and Touchstone Dynamic Global Allocation Fund (collectively referred to as the “Funds”) (four of the funds constituting the Touchstone Strategic Trust) (the “Trust”), including the portfolios of investments, as of December 31, 2017, and the related statements of operations and statement of cash flows of Touchstone Dynamic Equity Fund for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds (four of the funds constituting the Touchstone Strategic Trust) at December 31, 2017, the results of their operations and the cash flows of Touchstone Dynamic Equity Fund for the year then ended, the changes in their net assets for each of the two years in the period then ended and their financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Trust’s management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Trust is not required to have, nor were we engaged to perform, an audit of the Trust’s internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Trust’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2017, by correspondence with the custodian, transfer agent and brokers or by other appropriate auditing procedures where replies from brokers were not received. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more Touchstone Investments’ investment companies since 1999.

Proxy Voting Guidelines

The Sub-Advisors are responsible for exercising the voting rights associated with the securities purchased and held by the Funds. A description of the policies and procedures that the Sub-Advisors use in fulfilling this responsibility is available as an appendix to the most recent Statement of Additional Information, which can be obtained without charge by calling toll free 1.800.543.0407 or by visiting the Touchstone website at TouchstoneInvestments.com or on the Securities and Exchange Commission’s (the “Commission”) website sec.gov. Information regarding how those proxies were voted during the most recent twelve-month period ended June 30 is also available without charge by calling toll free 1.800.543.0407 or on the Commission’s website at sec.gov.

Quarterly Portfolio Disclosure

The Trust files a complete listing of portfolio holdings for each Fund as of the end of the first and third quarters of each fiscal year on Form N-Q. The complete listing (i) is available on the Commission’s website; (ii) may be reviewed and copied at the Commission’s Public Reference Room in Washington, DC; or (iii) will be made available to shareholders upon request by calling 1.800.543.0407. Information on the operation of the Public Reference Room may be obtained by calling 1.800.SEC.0330.

Schedule of Shareholder Expenses

As a shareholder of the Funds, you incur two types of costs: (1) transaction costs, including with respect to reinvested dividends or other distributions; and (2) ongoing costs, including investment advisory fees; distribution (12b-1)

Other Items (Unaudited) (Continued)

fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2017 through December 31, 2017).

Actual Expenses

The first line for each share class of a Fund in the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six Months Ended December 31, 2017” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line for each share class of a Fund in the table below provides information about hypothetical account values and hypothetical expenses based on the Funds’ actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Funds’ actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table below are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second line for each share class of a Fund in the table below is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Advisory and Sub-Advisory Agreement Approval Disclosure

At a meeting held on November 16, 2017, the Board of Trustees (the “Board” or “Trustees”) of the Touchstone Strategic Trust (the “Trust”), and by a separate vote, the Independent Trustees of the Trust, approved the continuance of the Investment Advisory Agreement between the Trust and the Advisor with respect to each Fund of the Trust, and the continuance of the Sub-Advisory Agreement between the Advisor and each Fund’s respective Sub-Advisor.

In determining whether to approve the continuation of the Investment Advisory Agreement and the Sub-Advisory Agreements, the Advisor furnished information necessary for a majority of the Independent Trustees to make the determination that the continuance of the Investment Advisory Agreement and each Sub-Advisory Agreement was in the best interests of the respective Funds and their shareholders. The information provided to the Board included: (1) industry data comparing advisory fees and total expense ratios of comparable funds; (2) comparative performance information; (3) the Advisor’s and its affiliates’ revenues and costs of providing services to the Funds; and (4) information about the Advisor’s and Sub-Advisors’ personnel. Prior to voting, the Independent Trustees reviewed the proposed continuance of the Investment Advisory Agreement and the Sub-Advisory Agreements with management and experienced independent legal counsel and received materials from such counsel discussing the legal standards for their consideration of the proposed continuation of the Investment Advisory Agreement and each Sub-Advisory Agreement. The Independent Trustees also reviewed the proposed continuation of the

Other Items (Unaudited) (Continued)

Investment Advisory Agreement and each Sub-Advisory Agreement with independent legal counsel in private sessions at which no representatives of management were present.

In approving the Funds’ Investment Advisory Agreement, the Board considered various factors, among them:

(1) the nature, extent and quality of services provided to the Funds, including the personnel providing such services; (2) the Advisor’s compensation and profitability; (3) a comparison of fees and performance with comparable funds; (4) economies of scale; and (5) the terms of the Investment Advisory Agreement. The Board’s analysis of these factors is set forth below. The Independent Trustees were advised by independent legal counsel throughout the process.

Nature, Extent and Quality of Advisor Services. The Board considered the level and depth of knowledge of the Advisor, including the professional experience and qualifications of senior personnel. In evaluating the quality of services provided by the Advisor, the Board took into account its familiarity with the Advisor’s senior management through Board meetings, discussions and reports during the preceding year. The Board also took into account the Advisor’s compliance policies and procedures. The quality of administrative and other services, including the Advisor’s role in coordinating the activities of the Funds’ other service providers, was also considered. The Board also considered the Advisor’s relationship with its affiliates and the resources available to them, as well as any potential conflicts of interest.

The Board discussed the Advisor’s effectiveness in monitoring the performance of each Sub-Advisor, and the Advisor’s timeliness in responding to performance issues. The Board considered the Advisor’s process for monitoring each of the Sub-Advisors, which includes an examination of both qualitative and quantitative elements of the Sub-Advisor’s organization, personnel, procedures, investment discipline, infrastructure and performance. The Board considered that the Advisor conducts regular on-site compliance visits with each Sub-Advisor, during which the Advisor examines a wide variety of factors, such as the financial condition of the Sub-Advisor, the quality of the Sub-Advisor’s systems, the effectiveness of the Sub-Advisor’s disaster recovery programs, trade allocation and execution procedures, compliance with the Sub-Advisor’s policies and procedures, results of regulatory examinations and any other factors that might affect the quality of services that the Sub-Advisor provides to the applicable Fund(s). The Board noted that the Advisor’s compliance monitoring processes also include quarterly reviews of compliance reports, and that any issues arising from such reports and the Advisor’s compliance visits to the Sub-Advisors are reported to the Board.

The Trustees concluded that they were satisfied with the nature, extent and quality of services provided to each Fund by the Advisor under the Investment Advisory Agreement.

Advisor’s Compensation and Profitability. The Board took into consideration the financial condition and profitability of the Advisor and its affiliates and the direct and indirect benefits derived by the Advisor and its affiliates from the Advisor’s relationship with the Funds. The information considered by the Board included operating profit margin information for the Advisor’s business as a whole. The Board noted that the Advisor had waived a portion of advisory fees and administrative fees and/or reimbursed expenses in order to limit each Fund’s net operating expenses. The Board also noted that the Advisor pays the Sub-Advisors’ sub-advisory fees out of the advisory fees the Advisor receives from the Funds. The Board reviewed the profitability of the Advisor’s relationship with the Funds both before and after tax expenses, and also considered whether the Advisor has the financial wherewithal to continue to provide services to the Funds, noting the ongoing commitment of the Advisor’s parent company with respect to providing support and resources as needed. The Board considered that the Funds’ distributor, an affiliate of the Advisor, receives Rule 12b-1 distribution fees from the Funds and receives a portion of the sales charges on sales or redemptions of certain classes of shares. The Board also noted that the Advisor derives benefits to its reputation and other benefits from its association with the Funds.

The Board recognized that the Advisor should be entitled to earn a reasonable level of profits in exchange for the level of services it provides to each Fund and the entrepreneurial risk that it assumes as Advisor. Based upon

Other Items (Unaudited) (Continued)

their review, the Trustees concluded that the Advisor’s and its affiliates’ level of profitability, if any, from their relationship with each Fund was reasonable and not excessive.

Expenses and Performance. The Board compared the respective advisory fees and total expense ratios for each of the Funds with various comparative data, including the median and average advisory fees and total expense ratios of each Fund’s respective peer group. The Board also considered, among other data, the Funds’ respective performance results during the six-month, twelve-month and thirty-six-month periods ended June 30, 2017, and noted that the Board reviews on a quarterly basis detailed information about each Fund’s performance results, portfolio composition and investment strategies. The Board also took into account current market conditions and their effect on the Funds’ performance.

The Board also considered the effect of each Fund’s growth and size on its performance and expenses. The Board noted that the Advisor had waived a portion of the fees and/or reimbursed expenses of the Funds in order to reduce the Funds’ respective operating expenses to targeted levels. The Board noted that the sub-advisory fees under the Sub-Advisory Agreement with respect to each Fund were paid by the Advisor out of the advisory fees it receives from the Fund and considered the impact of such sub-advisory fees on the profitability of the Advisor. In reviewing the respective total expense ratios and performance of each of the Funds, the Board also took into account the nature, extent and quality of the services provided to the Funds by the Advisor and its affiliates.

The Board considered, among other data, the specific factors and related conclusions set forth below with respect to each Fund:

Touchstone Dynamic Equity Fund. The Fund’s advisory fee and total expense ratio (net of applicable expense waivers and reimbursements) were at the median of its peer group. The Board noted that the Advisor was currently waiving and/or reimbursing a portion of the Fund’s fees and/or expenses. The Fund’s performance for the six-and twelve-month periods ended June 30, 2017 was in the 3^rd quintile of its peer group, and the Fund’s performance for the thirty-six-month period ended June 30, 2017 was in the 2^nd quintile of its peer group. Based upon their review, the Trustees concluded that the Fund’s overall performance was satisfactory relative to the performance of funds with similar investment objectives and relevant indices, and that the advisory fee was reasonable in light of the services received by the Fund from the Advisor and the other factors considered.

Touchstone Controlled Growth with Income Fund. The Fund’s advisory fee and total expense ratio (net of applicable expense waivers and reimbursements) were below the median and above the median, respectively, of its peer group. The Board noted that the Advisor was currently waiving and/or reimbursing a portion of the Fund’s fees and/or expenses. The Fund’s performance for the six-and twelve-month periods ended June 30, 2017 was in the 2^nd quintile of its peer group, and the Fund’s performance for the thirty-six month period ended June 30, 2017 was in the 1^st quintile of its peer group. Based upon their review, the Trustees concluded that the Fund’s overall performance was satisfactory relative to the performance of funds with similar investment objectives and relative indices, and that the advisory fee was reasonable in light of the services received by the Fund and the other factors considered.

Touchstone Dynamic Diversified Income Fund. The Fund’s advisory fee and total expense ratio (net of applicable expense waivers and reimbursements) were above the median of its peer group. The Board noted that the Advisor was currently waiving and/or reimbursing a portion of the Fund’s fees and/or expenses. The Fund’s performance for the six- and twelve- month periods ended June 30, 2017 was in the 4^th quintile of its peer group, and the Fund’s performance for the thirty-six-month period ended June 30, 2017 was in the 3^rd quintile of its peer group. The Board noted management’s discussion of the Fund’s performance including both its recent and long-term performance. Based upon their review, the Trustees concluded that the Fund’s overall performance

Other Items (Unaudited) (Continued)

was satisfactory relative to the performance of funds with similar investment objectives and relative indices, and that the advisory fee was reasonable in light of the services received by the Fund and the other factors considered.

Touchstone Dynamic Global Allocation Fund. The Fund’s advisory fee and total expense ratio (net of applicable expense waivers and reimbursements) were above the median and at the median, respectively, of its peer group. The Board noted that the Advisor was currently waiving and/or reimbursing a portion of the Fund’s fees and/or expenses. The Fund’s performance for the six-, twelve- and thirty-six-month periods ended June 30, 2017 was in the 3^rd quintile of its peer group. Based upon their review, the Trustees concluded that the Fund’s overall performance was satisfactory relative to the performance of funds with similar investment objectives and relative indices, and that the advisory fee was reasonable in light of the services received by the Fund and the other factors considered.

Economies of Scale. The Board considered the effect of each Fund’s current size and potential growth on its performance and expenses. The Board took into account management’s discussion of the Funds’ advisory fee structure. The Board considered the effective advisory fees under the Investment Advisory Agreement as a percentage of assets at different asset levels and possible economies of scale that might be realized if the assets of each Fund increase. The Board noted that the advisory fee schedules for the Funds contain breakpoints that would reduce the respective advisory fee rate on assets above specified levels as the respective Fund’s assets increased. The Board also noted that if a Fund’s assets increase over time, the Fund also might realize other economies of scale if assets increase proportionally more than certain other expenses. The Board also considered the fact that, under the Investment Advisory Agreement, the advisory fee payable to the Advisor by a Fund was reduced by the total sub-advisory fee paid by the Advisor to the Fund’s Sub-Advisor.

Conclusion. In considering the renewal of the Funds’ Investment Advisory Agreement, the Board, including the Independent Trustees, did not identify any single factor as controlling, and each Trustee may have attributed different weights to the various factors. The Trustees evaluated all information available to them on a Fund-by-Fund basis, and their determinations were made separately with respect to each Fund. The Board reached the following conclusions regarding the Funds’ Investment Advisory Agreement with the Advisor, among others: (a) the Advisor demonstrated that it possesses the capability and resources to perform the duties required of it under the Investment Advisory Agreement; (b) the Advisor maintains an appropriate compliance program; (c) the overall performance of each Fund is satisfactory relative to the performance of funds with similar investment objectives and relevant indices; and (d) each Fund’s advisory fee is reasonable in light of the services received by the Fund from the Advisor and the other factors considered. Based on their conclusions, the Trustees determined with respect to each Fund that continuation of the Investment Advisory Agreement was in the best interests of the Fund and its shareholders.

In approving the Funds’ respective Sub-Advisory Agreement, the Board considered various factors with respect to each Fund and the applicable Sub-Advisory Agreement, among them: (1) the nature, extent and quality of services provided to the Fund, including the personnel providing such services; (2) the Sub-Advisor’s compensation; (3) a comparison of the sub-advisory fee and performance with comparable funds; and (4) the terms of the Sub-Advisory Agreement. The Board’s analysis of these factors is set forth below. The Independent Trustees were advised by independent legal counsel throughout the process.

Nature, Extent and Quality of Services Provided; Investment Personnel. The Board considered information provided by the Advisor regarding the services provided by each Sub-Advisor, including information presented periodically throughout the previous year. The Board noted that, on a periodic basis, the Board meets with portfolio managers of the Sub-Advisors to discuss their respective performance and investment processes and strategies. The Board considered each Sub-Advisor’s level of knowledge and investment style. The Board reviewed the experience

Other Items (Unaudited) (Continued)

and credentials of the applicable investment personnel who are responsible for managing the investment of portfolio securities with respect to the Funds.

Sub-Advisor’s Compensation, Profitability and Economies of Scale. The Board also took into consideration the financial condition of each Sub-Advisor and any indirect benefits derived by each Sub-Advisor and its affiliates from the Sub-Advisor’s relationship with the Funds. In considering the profitability to each Sub-Advisor of its relationship with the Fund(s), the Board noted the undertaking of the Advisor to maintain expense limitations for the Funds and also noted that the sub-advisory fees under the Sub-Advisory Agreements were paid by the Advisor out of the advisory fees that it receives under the Investment Advisory Agreement and are negotiated at arm’s-length. As a consequence, the profitability to each Sub-Advisor of its relationship with a Fund was not a substantial factor in the Board’s deliberations. For similar reasons, the Board did not consider the potential economies of scale in each Sub-Advisor’s management of the applicable Fund to be a substantial factor in its consideration, although the Board noted that the sub-advisory fee schedule for each Fund contained breakpoints that would reduce the sub-advisory fee rate on assets above specified levels as the applicable Fund’s assets increased.

Sub-Advisory Fees and Fund Performance. The Board considered that each Fund pays an advisory fee to the Advisor and that the Advisor pays a sub-advisory fee to the Sub-Advisor out of the advisory fees it receives from the respective Fund. The Board also compared the sub-advisory fees paid by the Advisor to fees charged by the Touchstone Dynamic Equity Fund’s Sub-Advisor to manage comparable institutional separate accounts. The Board considered the amount retained by the Advisor and the sub-advisory fees paid to each Sub-Advisor with respect to the various services provided by the Advisor and the Sub-Advisor. The Board also noted that the Advisor negotiated the sub-advisory fee with each of the Sub-Advisors at arm’s-length. The Board reviewed the sub-advisory fee for each Fund in relation to various comparative data, including the median and average sub-advisory fees of each Fund’s peer group, and considered the following information:

Touchstone Dynamic Equity Fund. The Fund’s sub-advisory fee was at the median of its peer group. Based upon their review, the Trustees concluded that the sub-advisory fee was reasonable in light of the services received by the Fund from the Sub-Advisor and the other factors considered.

Touchstone Controlled Growth with Income Fund. The Fund’s sub-advisory fee was at the median of its peer group. Based upon their review, the Trustees concluded that the sub-advisory fee was reasonable in light of the services received by the Fund from the Sub-Advisor and the other factors considered.

Touchstone Dynamic Diversified Income Fund. The Fund’s sub-advisory fee was at the median of its peer group. Based upon their review, the Trustees concluded that the sub-advisory fee was reasonable in light of the services received by the Fund from the Sub-Advisor and the other factors considered.

Touchstone Dynamic Global Allocation Fund. The Trustees considered the Fund’s sub-advisory fee relative to the fees paid by other funds to their sub-advisors. Based upon their review, the Trustees concluded that the Fund’s sub-advisory fee was reasonable in light of the services received by the Fund from the Sub-Advisor and the other factors considered.

As noted above, the Board considered each Fund’s performance during the six-month, twelve-month and thirty-six-month periods ended June 30, 2017, as compared to each Fund’s peer group and noted that the Board reviews on a quarterly basis detailed information about each Fund’s performance results, portfolio composition and investment strategies. The Board also noted the Advisor’s expertise and resources in monitoring the performance, investment style and risk-adjusted performance of each Sub-Advisor. The Board also was mindful of the Advisor’s ongoing monitoring of each Sub-Advisor’s performance and the measures undertaken by the Advisor to address any underperformance.

Other Items (Unaudited) (Continued)

Conclusion. In considering the renewal of the Sub-Advisory Agreement with respect to each applicable Fund, the Board, including the Independent Trustees, did not identify any single factor as controlling, and each Trustee may have attributed different weights to the various factors. The Board reached the following conclusions regarding each Sub-Advisory Agreement, among others: (a) the Sub-Advisor is qualified to manage each Fund’s assets in accordance with the Fund’s investment goals and policies; (b) the Sub-Advisor maintains an appropriate compliance program; (c) the overall performance of each Fund is satisfactory relative to the performance of funds with similar investment objectives and relevant indices; (d) each Fund’s sub-advisory fee is reasonable in light of the services received by the Fund from the Sub-Advisor and the other factors considered; and (e) the Sub-Advisor’s investment strategies are appropriate for pursuing the investment goals of each Fund. Based on its conclusions, the Board determined that approval of the Sub-Advisory Agreement with respect to each applicable Fund was in the best interests of the Fund and its shareholders.

(d)

The fees relate to the PFIC Analyzer and Global Withholding Tax Reporter subscriptions.

(e)(1)

Disclose the audit committee's pre-approval policies and procedures described in paragraph (c)(7) of Rule 2-01 of Regulation S-X.

The Audit Committee’s pre-approval policies describe the types of audit, audit-related, tax and other services that have the general pre-approval of the Audit Committee. The pre-approval policies provide that annual audit service fees, tax services not specifically granted pre-approval, services exceeding pre-approved cost levels and other services that have not received general pre-approval will be subject to specific pre-approval by the Audit Committee. The pre-approval policies further provide that the Committee may grant general pre-approval to other audit services (statutory audits and services associated with SEC registration statements, periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings), audit-related services (accounting consultations related to accounting, financial reporting or disclosure matters not classified as “audit services,” assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities, agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters and assistance with internal control reporting requirements under Form N-SAR and Form N-CSR), tax services that have historically been provided by the auditor that the Committee believes would not impair the independence of the auditor and are consistent with the SEC’s rules on auditor independence and permissible non-audit services classified as “all other services” that are routine and recurring services.

(e)(2)

All of the services described in paragraphs (c) through (d) of Item 4 were approved by the Audit Committee.

(f)

The percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees was less than fifty percent.

(g)

The aggregate non-audit fees for Touchstone Strategic Trust (December Funds) and certain entities*, totaled approximately $14,807 and $13,941 for the fiscal years ended December 31, 2017 and 2016, respectively.

* These include the advisors (excluding sub-advisors) and any entity controlling, controlled by or under common control with the advisors that provides ongoing services to the registrant (Funds).

(h)

The registrant's audit committee of the board of directors has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
