Commodity Futures Trading Commission Registration. Effective December 31, 2012, the Commodity Futures Trading Commission (“CFTC”) adopted certain regulatory changes that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. The investment adviser has claimed an exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of the Fund. Accordingly, neither the Fund nor the adviser with respect to the operation of the Fund is subject to CFTC regulation. Because of its management of other strategies, the Fund’s adviser is registered with the CFTC as a commodity pool operator. The adviser is also registered as a commodity trading advisor.

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

This report must be preceded or accompanied by a current summary prospectus or prospectus. Before investing in NextShares, investors should consider carefully the investment objectives, risks, charges and expenses. This and other important information is contained in the prospectus and summary prospectus, which can be obtained from a financial advisor. Prospective investors should read the prospectus carefully before investing. For further information, please call 1-800-262-1122.

Past performance is no guarantee of future results. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance is for the stated time period only; due to market volatility, Fund performance may be lower or higher than the quoted return. The Fund’s performance at market price will differ from its results at net asset value (NAV). The market price used to calculate the Market Price return is the midpoint between the highest bid and the lowest offer on the exchange on which the shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. If you trade your shares at another time during the day, your return may differ. Returns are historical and are calculated by determining the percentage change in NAV or market price (as applicable) with all distributions reinvested at NAV or closing market price (as applicable) on the payment date of the distribution, and are net of management fees and other expenses. Performance for periods less than or equal to one year is cumulative. For performance as of the most recent month-end, including historical trading premiums/discounts relative to NAV, please refer to eatonvance.com

Endnotes and Additional Disclosures

¹  Shares of NextShares funds are normally bought and sold in the secondary market through a broker, and may not be individually purchased or redeemed from the fund. In the secondary market, buyers and sellers transact with each other, rather than with the fund. NextShares funds issue and redeem shares only in specified creation unit quantities in transactions by or through Authorized Participants. In such transactions, a fund issues and redeems shares in exchange for the basket of securities, other instruments and/or cash that the fund specifies each business day. By transacting in kind, a NextShares fund can lower its trading costs and enhance fund tax efficiency by avoiding forced sales of securities to meet redemptions. Redemptions may be effected partially or entirely in cash when in-kind delivery is not practicable or deemed not in the best interests of shareholders. A fund’s basket is not intended to be representative of the fund’s current portfolio positions and may vary significantly from current positions. As exchange-traded securities, NextShares can operate with low transfer agency expenses by utilizing the same highly efficient share processing system as used for exchange-listed stocks and exchange-traded funds.

Market trading prices of NextShares are linked to the fund’s next-computed net asset value (NAV) and will vary from NAV by a market-determined premium or discount, which may be zero. Buyers and sellers of NextShares will not know the value of their purchases and sales until after the fund’s NAV is determined at the end of the trading day. Market trading prices may vary significantly from anticipated levels. NextShares do not offer investors the opportunity to buy and sell intraday based on current (versus end- of-day) determinations of fund value. NextShares trade execution prices will fluctuate based on changes in NAV. Although limit orders may be used to control trading costs, they cannot be used to control or limit trade execution prices. As a new type of fund, NextShares have a limited operating history and may initially be available through a limited number of brokers. There can be no guarantee that an active trading market for NextShares will develop or be maintained, or that their listing will continue unchanged. Buying and selling NextShares may require payment of brokerage commissions and expose transacting shareholders to other trading costs. Frequent trading may detract from realized investment returns. The return on a shareholder’s NextShares investment will be reduced if the shareholder sells shares at a greater discount or narrower premium to NAV than he or she acquired the shares.

²  S&P 500^® Index is an unmanaged index of large-cap stocks commonly used as a measure of U.S. stock market performance.

Unless otherwise stated, index returns do not reflect the effect of any applicable sales charges, commissions, expenses, taxes or leverage, as applicable. It is not possible to invest directly in an index. Performance since inception for an index, if presented, is the performance since the Fund’s or oldest share class’ inception, as applicable.

³  The Fund pursues its investment objective by investing in a separate investment fund (the Portfolio). The returns at NAV for periods before the date the Fund commenced operations are for a mutual fund that invests in the Portfolio (the Portfolio Investor). The performance during such period does not represent the performance of the Fund. The prior investment performance of the Portfolio Investor (rather than the Portfolio itself) is shown because it reflects the expenses typically borne by a retail fund investing in the Portfolio. The Portfolio Investor returns are not adjusted to reflect differences between the total net operating expenses of the Fund and the Portfolio Investor during the periods shown. If such an adjustment were made, the performance presented would be higher, because the Fund’s total net operating expenses are lower than those of the Portfolio Investor. Performance is for a share class of the Portfolio Investor offered at net asset value. Performance presented in the Financial Highlights included in the financial statements is not linked.

⁴  Source: Fund prospectus. Net expense ratios reflect a contractual expense reimbursement that continues through 4/30/21. Without the reimbursement, performance would have been lower. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report.

⁵  Fund primarily invests in an affiliated investment company (Portfolio) with substantially the same objective(s) and policies as the Fund and may also invest directly. Unless otherwise noted, references to investments are to the aggregate holdings of the Fund and the Portfolio.

⁶  Excludes cash and cash equivalents.

Fund Expenses

Example:  As a Fund shareholder, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares; and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of Fund investing and to compare these costs with the ongoing costs of investing in other funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (January 1, 2020 – June 30, 2020).

Actual Expenses:  The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, 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 section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes:  The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the actual Fund expense ratio and an assumed rate of return of 5% per year (before expenses), which is not the actual Fund 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 your Fund 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 are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as brokerage commissions on purchases and sales of Fund shares. Therefore, the second section of the table 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 be higher.

	Beginning Account Value (1/1/20)		Ending Account Value (6/30/20)		Expenses Paid During Period* (1/1/20 – 6/30/20)			Annualized Expense Ratio
Actual
	$	1,000.00	$	980.90	$	3.20	**		0.65	%
Hypothetical
(5% return per year before expenses)
	$	1,000.00	$	1,021.60	$	3.27	**		0.65	%

* Expenses are equal to the Fund’s annualized expense ratio, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period). The Example assumes that the $1,000 was invested at the net asset value per share determined at the close of business on December 31, 2019. The Example reflects the expenses of both the Fund and the Portfolio.

** Absent an allocation of certain expenses to an affiliate, expenses would be higher.

Notes to Financial Statements (Unaudited)

1  Significant Accounting Policies

Eaton Vance Stock NextShares (the Fund) is a diversified series of Eaton Vance NextShares Trust (the Trust), a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act). The Fund is an exchange-traded managed fund operating pursuant to an order issued by the SEC granting an exemption from certain provisions of the 1940 Act. Individual shares of the Fund may be purchased and sold only on a national securities exchange or alternative trading system through a broker-dealer that offers NextShares, and may not be directly purchased or redeemed from the Fund. Market trading prices for the Fund are directly linked to the Fund’s next-computed net asset value per share (NAV) and will vary from NAV by a market-determined premium or discount, which may be zero. The Fund invests all of its investable assets in interests in Stock Portfolio (the Portfolio), a Massachusetts business trust having substantially the same investment objective and policies as the Fund. The value of the Fund’s investment in the Portfolio reflects the Fund’s proportionate interest in the net assets of the Portfolio (1.0% at June 30, 2020). The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio, including the portfolio of investments, are included elsewhere in this report and should be read in conjunction with the Fund’s financial statements.

The following is a summary of significant accounting policies of the Fund. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946.

A  Investment Valuation — Valuation of securities by the Portfolio is discussed in Note 1A of the Portfolio’s Notes to Financial Statements, which are included elsewhere in this report.

B  Income — The Fund’s net investment income or loss consists of the Fund’s pro-rata share of the net investment income or loss of the Portfolio, less all actual and accrued expenses of the Fund.

C  Federal Taxes — The Fund’s policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year substantially all of its net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary.

As of June 30, 2020, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Fund files a U.S. federal income tax return annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

D  Expenses — The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated taking into consideration, among other things, the nature and type of expense and the relative size of the funds.

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

F  Indemnifications — Under the Trust’s organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Fund. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Trust) could be deemed to have personal liability for the obligations of the Trust. However, the Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and the By-laws provide that the Trust shall assume, upon request by the shareholder, the defense on behalf of any Fund shareholders. Moreover, the By-laws also provide for indemnification out of Fund property of any shareholder held personally liable solely by reason of being or having been a shareholder for all loss or expense arising from such liability. Additionally, in the normal course of business, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

G  Other — Investment transactions are accounted for on a trade date basis.

H  Interim Financial Statements — The interim financial statements relating to June 30, 2020 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2  Distributions to Shareholders and Income Tax Information

It is the present policy of the Fund to make at least one distribution annually (normally in December) of all or substantially all of its net investment income and to distribute annually all or substantially all of its net realized capital gains. Distributions are paid in cash and cannot be automatically reinvested in additional shares of the Fund. Distributions to shareholders are recorded on the ex-dividend date. Distributions to shareholders are determined in accordance with income tax regulations, which may differ from U.S. GAAP. As required by U.S. GAAP, only distributions in excess of tax basis earnings and profits are reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income.

3  Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Eaton Vance Management (EVM) as compensation for investment advisory services rendered to the Fund. The fee is computed at an annual rate of 0.60% of the Fund’s average daily net assets that are not invested in other investment companies for which EVM or its affiliates serve as investment adviser and receive an advisory fee (“Direct Assets”) up to $500 million and is payable monthly. On Direct Assets of $500 million and over, the annual fee is reduced. For the six months ended June 30, 2020, the Fund incurred no investment adviser fee on Direct Assets. To the extent the Fund’s assets are invested in the Portfolio, the Fund is allocated its share of the Portfolio’s investment adviser fee. The Portfolio has engaged Boston Management and Research (BMR), a subsidiary of EVM, to render investment advisory services. See Note 2 of the Portfolio’s Notes to Financial Statements which are included elsewhere in this report. EVM also serves as the administrator of the Fund, but receives no compensation.

The Trust, on behalf of the Fund, has entered into an operations agreement with EVM pursuant to which EVM provides the Fund with services required for it to operate as a NextShares exchange-traded managed fund in accordance with the exemptive order obtained by EVM and the Trust. Pursuant to the agreement, the Fund pays EVM a monthly fee at an annual rate of 0.05% of the Fund’s average daily net assets provided the average net assets of NextShares funds sponsored by EVM (“Covered Assets”) are less than $10 billion. The annual rate is reduced if Covered Assets are $10 billion and above. For the six months ended June 30, 2020, the operations agreement fee amounted to $1,538 or 0.05% (annualized) of the Fund’s average daily net assets.

EVM has agreed to reimburse the Fund’s expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only) exceed 0.65% of the Fund’s average daily net assets through April 30, 2021. Thereafter, the reimbursement may be changed or terminated at any time. Pursuant to this agreement, EVM was allocated $53,051 of the Fund’s operating expenses for the six months ended June 30, 2020.

Trustees and officers of the Fund who are members of EVM’s or BMR’s organizations receive remuneration for their services to the Fund out of the investment adviser fee. Certain officers and Trustees of the Fund and the Portfolio are officers of the above organizations.

4  Investment Transactions

For the six months ended June 30, 2020, increases and decreases in the Fund’s investment in the Portfolio aggregated $187,087 and $195,421, respectively. In addition, a Portfolio transaction fee is imposed by the Portfolio on the combined daily inflows or outflows of the Fund and the Portfolio’s other investors as more fully described at Note 1H of the Portfolio’s financial statements included herein. Such fee is allocated to the Fund based on its pro-rata interest in the Portfolio. The amount of the Portfolio transaction fee imposed on the Fund, if any, and the allocation of such fee are presented as Other capital on the Statements of Changes in Net Assets.

5  Capital Share Transactions

The Trust may issue an unlimited number of shares of capital stock (no par value per share) in one or more series (such as the Fund). The Fund issues and redeems shares only in blocks of 25,000 shares or multiples thereof (“Creation Units”). The Fund issues and redeems Creation Units in return for the securities, other instruments and/or cash (the “Basket”) that the Fund specifies each business day. Creation Units may be purchased or redeemed only by or through Authorized Participants, which are broker-dealers or institutional investors that have entered into agreements with the Fund’s distributor for this purpose. The Fund imposes a transaction fee on Creation Units issued and redeemed to offset the estimated cost to the Fund of processing the transaction, which is paid by the Authorized Participants directly to a third-party administrator. In addition, Authorized Participants pay the Fund a variable charge for converting the Basket to or from the desired portfolio composition. Such variable charges are reflected as Transaction fees on the Statements of Changes in Net Assets.

At June 30, 2020, EVM owned approximately 96% of the outstanding shares of the Fund.

1  Significant Accounting Policies

Stock Portfolio (the Portfolio) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, open-end management investment company. The Portfolio’s investment objective is to achieve long-term capital appreciation by investing in a diversified portfolio of equity securities. The Declaration of Trust permits the Trustees to issue interests in the Portfolio. At June 30, 2020, Eaton Vance Stock Fund, Eaton Vance Stock NextShares and Eaton Vance Balanced Fund held an interest of 13.9%, 1.0% and 85.0%, respectively, in the Portfolio.

The following is a summary of significant accounting policies of the Portfolio. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Portfolio is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946.

A  Investment Valuation — The following methodologies are used to determine the market value or fair value of investments.

Equity Securities. Equity securities listed on a U.S. securities exchange generally are valued at the last sale or closing price on the day of valuation or, if no sales took place on such date, at the mean between the closing bid and ask prices on the exchange where such securities are principally traded. Equity securities listed on the NASDAQ Global or Global Select Market generally are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and ask prices.

Foreign Securities and Currencies. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rate quotations supplied by a third party pricing service. The pricing service uses a proprietary model to determine the exchange rate. Inputs to the model include reported trades and implied bid/ask spreads. The daily valuation of exchange-traded foreign securities generally is determined as of the close of trading on the principal exchange on which such securities trade. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the New York Stock Exchange. When valuing foreign equity securities that meet certain criteria, the Portfolio’s Trustees have approved the use of a fair value service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that have a strong correlation to the fair-valued securities.

Affiliated Fund. The Portfolio may invest in Eaton Vance Cash Reserves Fund, LLC (Cash Reserves Fund), an affiliated investment company managed by
Eaton Vance Management (EVM). While Cash Reserves Fund is not a registered money market mutual fund, it conducts all of its investment activities in accordance with the requirements of Rule 2a-7 under the 1940 Act. Investments in Cash Reserves Fund are valued at the closing net asset value per unit on the valuation day. Cash Reserves Fund generally values its investment securities based on available market quotations provided by a third party pricing service.

Fair Valuation. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued at fair value using methods determined in good faith by or at the direction of the Trustees of the Portfolio in a manner that most fairly reflects the security’s “fair value”, which is the amount that the Portfolio might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies or entities, quotations or relevant information obtained from broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial statements, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B  Investment Transactions — Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost.

C  Income — Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. However, if the ex-dividend date has passed, certain dividends from foreign securities are recorded as the Portfolio is informed of the ex-dividend date. Withholding taxes on foreign dividends and capital gains have been provided for in accordance with the Portfolio’s understanding of the applicable countries’ tax rules and rates.

D  Federal Taxes — The Portfolio has elected to be treated as a partnership for federal tax purposes. No provision is made by the Portfolio for federal or state taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes on its share of taxable income. Since at least one of the Portfolio’s investors is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the applicable source of income and diversification requirements (under the Internal Revenue Code) in order for its investors to satisfy them. The Portfolio will allocate, at least annually among its investors, each investor’s distributive share of the Portfolio’s net investment income, net realized capital gains and losses and any other items of income, gain, loss, deduction or credit.

As of June 30, 2020, the Portfolio had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Portfolio files a U.S. federal income tax return annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

E  Foreign Currency Translation — Investment valuations, other assets, and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investment securities and income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates in effect on the respective dates of such transactions. Recognized

June 30, 2020

Notes to Financial Statements (Unaudited) — continued

gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net realized gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

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

G  Indemnifications — Under the Portfolio’s organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Portfolio. Under Massachusetts law, if certain conditions prevail, interestholders in the Portfolio could be deemed to have personal liability for the obligations of the Portfolio. However, the Portfolio’s Declaration of Trust contains an express disclaimer of liability on the part of Portfolio interestholders. Additionally, in the normal course of business, the Portfolio enters into agreements with service providers that may contain indemnification clauses. The Portfolio’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Portfolio that have not yet occurred.

H  Capital Transactions — To seek to protect the Portfolio (and, indirectly, other investors in the Portfolio) against the costs of accommodating investor inflows and outflows, the Portfolio imposes a fee (“Portfolio transaction fee”) on inflows and outflows by Portfolio investors. The Portfolio transaction fee is sized to cover the estimated cost to the Portfolio of, in connection with issuing interests, converting the cash and/or other instruments it receives to the desired composition and, in connection with redeeming its interests, converting Portfolio holdings to cash and/or other instruments to be distributed. Such fee, which may vary over time, is limited to amounts that have been authorized by the Board of Trustees and determined by EVM to be appropriate. The maximum Portfolio transaction fee is 2% of the amount of net contributions or withdrawals. The Portfolio transaction fee is recorded as a component of capital transactions on the Statements of Changes in Net Assets.

I  Interim Financial Statements — The interim financial statements relating to June 30, 2020 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Portfolio’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2  Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Boston Management and Research (BMR), a subsidiary of EVM, as compensation for investment advisory services rendered to the Portfolio. Pursuant to the investment advisory agreement and subsequent fee reduction agreement between the Portfolio and BMR, the fee is computed at an annual rate of 0.60% of the Portfolio’s average daily net assets up to $500 million and 0.575% from $500 million but less than $1 billion, and is payable monthly. On net assets of $1 billion or over, the annual fee is reduced. The fee reduction cannot be terminated or reduced without the approval of a majority vote of the Trustees of the Portfolio who are not interested persons of BMR or the Portfolio and by the vote of a majority of the holders of interest in the Portfolio. For the six months ended June 30, 2020, the Portfolio’s investment adviser fee amounted to $1,911,770 or 0.59% (annualized) of the Portfolio’s average daily net assets. The Portfolio invests its cash in Cash Reserves Fund. EVM does not currently receive a fee for advisory services provided to Cash Reserves Fund.

Trustees and officers of the Portfolio who are members of EVM’s or BMR’s organizations receive remuneration for their services to the Portfolio out of the investment adviser fee. Trustees of the Portfolio who are not affiliated with the investment adviser may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended June 30, 2020, no significant amounts have been deferred. Certain officers and Trustees of the Portfolio are officers of the above organizations.

3  Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, aggregated $251,715,258 and $243,218,937, respectively, for the six months ended June 30, 2020

4  Federal Income Tax Basis of Investments

The cost and unrealized appreciation (depreciation) of investments of the Portfolio at June 30, 2020, as determined on a federal income tax basis, were as follows:

Aggregate cost	$	498,175,767
Gross unrealized appreciation	$	176,976,603
Gross unrealized depreciation		(8,711,278	)
Net unrealized appreciation	$	168,265,325

5  Line of Credit

The Portfolio participates with other portfolios and funds managed by EVM and its affiliates in an $800 million unsecured line of credit agreement with a group of banks, which is in effect through October 27, 2020. In connection with the renewal of the agreement on October 29, 2019, funds managed by Calvert Research and Management, an affiliate of EVM, were added as participating funds to the agreement and the borrowing limit was increased from $625 million. Borrowings are made by the Portfolio solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Portfolio based on its borrowings at an amount above either the Eurodollar rate or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. Because the line of credit is not available exclusively to the Portfolio, it may be unable to borrow some or all of its requested amounts at any particular time. The Portfolio did not have any significant borrowings or allocated fees during the six months ended June 30, 2020.

6  Investments in Affiliated Funds

At June 30, 2020, the value of the Portfolio’s investment in affiliated funds was $1,386,725, which represents 0.2% of the Portfolio’s net assets. Transactions in affiliated funds by the Portfolio for the six months ended June 30, 2020 were as follows:

7  Fair Value Measurements

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

• Level 1 – quoted prices in active markets for identical investments

• Level 2 – other significant observable inputs (including quoted prices for similar investments, 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)

In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

8  Risks and Uncertainties

Pandemic Risk

An outbreak of respiratory disease caused by a novel coronavirus that was first detected in China in December 2019 has spread rapidly internationally. This coronavirus has resulted in closing borders, enhanced health screenings, changes to healthcare service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of this outbreak has negatively affected the worldwide economy, as well as the economies of individual countries and individual companies and can affect the market in general in significant and unforeseen ways. Health crises caused by outbreaks, such as the coronavirus outbreak, may exacerbate other pre-existing political, social and economic risks and disrupt normal market conditions and operations. The near-term impact of this coronavirus has resulted in substantial market volatility, which may have an adverse effect on the Portfolio’s investments.

Board of Trustees’ Contract Approval

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended (the “1940 Act”), provides, in substance, that the investment advisory agreement between a fund and its investment adviser will continue in effect from year-to-year only if its continuation is approved on an annual basis by a vote of the fund’s board of trustees, including a majority of the trustees who are not “interested persons” of the fund (“independent trustees”), cast in person at a meeting called for the purpose of considering such approval.

At a meeting held on April 22, 2020 (the “April 2020 Meeting”), the Boards of Trustees/Directors comprised of the same individuals (collectively, the “Board”) that oversees a majority of the registered investment companies advised by Eaton Vance Management or its affiliate, Boston Management and Research (the “Eaton Vance Funds”), including a majority of the independent trustees (the “Independent Trustees”), voted to approve the continuation of existing investment advisory agreements and sub-advisory agreements⁽¹⁾ for each of the Eaton Vance Funds for an additional one-year period. The Board relied upon the affirmative recommendation of its Contract Review Committee, which is a committee exclusively comprised of Independent Trustees. Prior to making its recommendation, the Contract Review Committee reviewed information furnished by the adviser and sub-adviser to each of the Eaton Vance Funds (including information specifically requested by the Board) for a series of formal meetings held between February and April 2020. Members of the Contract Review Committee also considered information received at prior meetings of the Board and its committees, to the extent such information was relevant to the Contract Review Committee’s annual evaluation of the investment advisory agreements and sub-advisory agreements.

In connection with its evaluation of the investment advisory agreements and sub-advisory agreements, the Board considered various information relating to the Eaton Vance Funds. This included information applicable to all or groups of Eaton Vance Funds, which is referenced immediately below, and information applicable to the particular Eaton Vance Fund covered by this report (additional fund-specific information is referenced below under “Results of the Contract Review Process”). (For funds that invest through one or more underlying portfolios, references to “each fund” in this section may include information that was considered at the portfolio-level.)

Information about Fees, Performance and Expenses

• A report from an independent data provider comparing advisory and other fees paid by each fund to such fees paid by comparable funds, as identified by the independent data provider (“comparable funds”);

• A report from an independent data provider comparing each fund’s total expense ratio (and its components) to those of comparable funds;

• A report from an independent data provider comparing the investment performance of each fund (including, as relevant, total return data, income data, Sharpe ratios and information ratios) to the investment performance of comparable funds and, as applicable, benchmark indices, over various time periods;

• In certain instances, data regarding investment performance relative to customized groups of peer funds and blended indices identified by the adviser in consultation with the Portfolio Management Committee of the Board;

• Comparative information concerning the fees charged and services provided by the adviser and sub-adviser to each fund in managing other accounts (which may include other mutual funds, collective investment funds and institutional accounts) using investment strategies and techniques similar to those used in managing such fund(s), if any;

• Profitability analyses with respect to the adviser and sub-adviser to each of the funds;

Information about Portfolio Management and Trading

• Descriptions of the investment management services provided to each fund, as well as each of the funds’ investment strategies and policies;

• The procedures and processes used to determine the fair value of fund assets, when necessary, and actions taken to monitor and test the effectiveness of such procedures and processes;

• Information about the policies and practices of each fund’s adviser and sub-adviser (in the context of a sub-adviser, only those with trading responsibilities) with respect to trading, including their processes for seeking best execution of portfolio transactions;

• Information about the allocation of brokerage transactions and the benefits, if any, received by the adviser and sub-adviser (in the context of a sub-adviser, only those with trading responsibilities) to each fund as a result of brokerage allocation, including, as applicable, information concerning the acquisition of research through client commission arrangements and policies with respect to “soft dollars”;

• Data relating to the portfolio turnover rate of each fund;

Information about each Adviser and Sub-adviser

• Reports detailing the financial results and condition of the adviser and sub-adviser to each fund;

• Information regarding the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and, for portfolio managers and certain other investment professionals, information relating to their responsibilities with respect to managing other mutual funds and investment accounts, as applicable;

⁽¹⁾  Not all Eaton Vance Funds have entered into a sub-advisory agreement with a sub-adviser. Accordingly, references to “sub-adviser” or “sub-advisory agreement” in this “Overview” section may not be applicable to the particular Eaton Vance Fund covered by this report.

• The Code of Ethics of the adviser and its affiliates and the sub-adviser of each fund, together with information relating to compliance with, and the administration of, such codes;

• Policies and procedures relating to proxy voting and the handling of corporate actions and class actions;

• Information concerning the resources devoted to compliance efforts undertaken by the adviser and its affiliates and the sub-adviser of each fund, if any, including descriptions of their various compliance programs and their record of compliance;

• Information concerning the business continuity and disaster recovery plans of the adviser and its affiliates and the sub-adviser of each fund, if any;

• A description of Eaton Vance Management’s and Boston Management and Research’s oversight of sub-advisers, including with respect to regulatory and compliance issues, investment management and other matters;

Other Relevant Information

• Information concerning the nature, cost and character of the administrative and other non-investment advisory services provided by Eaton Vance Management and its affiliates;

• Information concerning oversight of the relationship with the custodian, subcustodians and fund accountants by the adviser and/or administrator to each of the funds;

• For an Eaton Vance Fund structured as an exchange-listed closed-end fund, information concerning the benefits of the closed-end fund structure, as well as, where relevant, the closed-end fund’s market prices, trading volume data, distribution rates and other relevant matters; and

• The terms of each investment advisory agreement and sub-advisory agreement.

During the various meetings of the Board and its committees throughout the twelve months ended April 2020, the Trustees received information from portfolio managers and other investment professionals of the advisers and sub-advisers of the funds regarding investment and performance matters, and considered various investment and trading strategies used in pursuing the funds’ investment objectives. The Trustees also received information regarding risk management techniques employed in connection with the management of the funds. The Board and its committees evaluated issues pertaining to industry and regulatory developments, compliance procedures, fund governance and other issues with respect to the funds, and received and participated in reports and presentations provided by Eaton Vance Management, Boston Management and Research and fund sub-advisers, with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Trustees held regular teleconferences to discuss, among other topics, matters relating to the continuation of investment advisory agreements and sub-advisory agreements.

The Contract Review Committee was advised throughout the contract review process by Goodwin Procter LLP, independent legal counsel for the Independent Trustees. The members of the Contract Review Committee, with the advice of such counsel, exercised their own business judgment in determining the material factors to be considered in evaluating each investment advisory agreement and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each investment advisory agreement and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Contract Review Committee may have placed varying emphasis on particular factors in reaching conclusions with respect to each investment advisory agreement and sub-advisory agreement. In evaluating each investment advisory agreement and sub-advisory agreement, including the fee structures and other terms contained in such agreements, the members of the Contract Review Committee were also informed by multiple years of analysis and discussion with the adviser and sub-adviser to each of the Eaton Vance Funds.

In voting its approval of the continuation of existing investment advisory agreements and sub-advisory agreements at the April 2020 Meeting, the Board relied on an order issued by the Securities and Exchange Commission on March 25, 2020, which provided temporary relief from the in-person voting requirements under Section 15 of the 1940 Act in response to the impacts of the COVID-19 pandemic.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information it deemed relevant, including the factors and conclusions described below, the Contract Review Committee concluded that the continuation of the investment advisory and administrative agreement between Eaton Vance Stock NextShares (the “Fund”) and Eaton Vance Management (“EVM”), as well as the investment advisory agreement between Stock Portfolio (the “Portfolio”), the portfolio in which the Fund invests, and Boston Management and Research (“BMR”) (EVM, with respect to the Fund, and BMR, with respect to the Portfolio, are each referred to herein as the “Adviser”), including their respective fee structures, are in the interests of shareholders and, therefore, recommended to the Board approval of each agreement. Based on the recommendation of the Contract Review Committee, the Board, including a majority of the Independent Trustees, voted to approve continuation of the investment advisory and administrative agreement for the Fund and the investment advisory agreement for the Portfolio (together, the “investment advisory agreements”).

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory agreements for the Fund and the Portfolio, the Board evaluated the nature, extent and quality of services provided to the Fund and the Portfolio by the applicable Adviser.

June 30, 2020

Board of Trustees’ Contract Approval — continued

The Board considered each Adviser’s management capabilities and investment processes in light of the types of investments held by the Fund and the Portfolio, including the education, experience and number of investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Fund and the Portfolio. The Board specifically noted that each Adviser has devoted extensive resources to in-house equity research and also draws upon independent research available from third-party sources. The Board also took into account the resources dedicated to portfolio management and other services, the compensation methods of each Adviser and other factors, including the reputation and resources of the Adviser to recruit and retain highly qualified research, advisory and supervisory investment professionals. In addition, the Board considered the time and attention devoted to the Eaton Vance Funds, including the Fund and the Portfolio, by senior management, as well as the infrastructure, operational capabilities and support staff in place to assist in the portfolio management and operations of the Fund and the Portfolio, including the provision of administrative services. The Board also considered the business-related and other risks to which each Adviser or its affiliates may be subject in managing the Fund and the Portfolio.

The Board considered the special attributes of the Fund relative to a traditional mutual fund and the benefits that are expected to be realized from an investment in the Fund, rather than a traditional mutual fund. The Board also considered the resources devoted by the applicable Adviser and its affiliates in developing and maintaining an infrastructure necessary to support the on-going operations of the Fund.

The Board noted that under the terms of the investment advisory agreement of the Fund, EVM may invest assets of the Fund directly in securities, for which it would receive a fee, or in the Portfolio, for which it receives no separate fee but for which BMR receives an advisory fee from the Portfolio.

The Board considered the compliance programs of each Adviser and relevant affiliates thereof. The Board considered compliance and reporting matters regarding, among other things, personal trading by investment professionals, disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also considered the responses of each Adviser and its affiliates to requests in recent years from regulatory authorities, such as the Securities and Exchange Commission and the Financial Industry Regulatory Authority.

The Board considered other administrative services provided or overseen by Eaton Vance Management and its affiliates, including transfer agency and accounting services. The Board evaluated the benefits to shareholders of investing in a fund that is a part of a large fund complex offering exposure to a variety of asset classes and investment disciplines.

After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by each Adviser, taken as a whole, are appropriate and consistent with the terms of the applicable investment advisory agreement.

Fund Performance

The Board compared the Fund’s investment performance to that of comparable funds identified by an independent data provider (the peer group), as well as an appropriate benchmark index and a customized peer group of similarly managed funds. The Board’s review included comparative performance data with respect to the Fund for the one-, three-, five- and ten-year periods ended September 30, 2019. In this regard, the Board noted that the performance of the Fund was higher than the median performance of the Fund’s peer group and custom peer group for the three-year period. The Board also noted that the performance of the Fund was lower than its benchmark index for the three-year period. The Board concluded that the performance of the Fund was satisfactory.

Management Fees and Expenses

The Board considered contractual fee rates payable by the Fund and by the Portfolio for advisory and administrative services (referred to collectively as “management fees”). As part of its review, the Board considered the Fund’s management fees and total expense ratio for the one-year period ended September 30, 2019, as compared to those of comparable funds, before and after giving effect to any undertaking to waive fees or reimburse expenses. The Board also received and considered information about the services offered and the fee rates charged by the Adviser to other types of accounts with investment objectives and strategies that are substantially similar to and/or managed in a similar investment style as the Fund. In this regard, the Board received information about the differences in the nature and scope of services the Adviser provides to the Fund as compared to other types of accounts and the material differences in compliance, reporting and other legal burdens and risks to the Adviser as between the Fund and other types of accounts. The Board also considered certain factors identified by management in response to inquiries from the Contract Review Committee regarding the Fund’s total expense ratio relative to comparable funds.

After considering the foregoing information, and in light of the nature, extent and quality of the services provided by each Adviser, the Board concluded that the management fees charged for advisory and related services are reasonable.

Profitability and “Fall-Out” Benefits

The Board considered the level of profits realized by each Adviser and relevant affiliates thereof in providing investment advisory and administrative services to the Fund, to the Portfolio and to all Eaton Vance Funds as a group. The Board considered the level of profits realized without regard to marketing support or other payments by each Adviser and its affiliates to third parties in respect of distribution or other services.

June 30, 2020

Board of Trustees’ Contract Approval — continued

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by each Adviser and its affiliates are deemed not to be excessive.

The Board also considered direct or indirect fall-out benefits received by each Adviser and its affiliates in connection with their respective relationships with the Fund and the Portfolio, including the benefits of research services that may be available to each Adviser as a result of securities transactions effected for the Fund and the Portfolio and other investment advisory clients.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the applicable Adviser and its affiliates, on the one hand, and the Fund and the Portfolio, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund and the Portfolio increase. The Board acknowledged the difficulty in accurately measuring the benefits resulting from economies of scale, if any, with respect to the management of any specific fund or group of funds. The Board reviewed data summarizing the increases and decreases in the assets of the Fund and of all Eaton Vance Funds as a group over various time periods, and evaluated the extent to which the total expense ratio of the Fund and the profitability of each Adviser and its affiliates may have been affected by such increases or decreases. Based upon the foregoing, the Board concluded that the Fund currently shares in the benefits from economies of scale, if any, when they are realized by the Adviser. The Board also concluded that the structure of the advisory fees, which include breakpoints at several asset levels, will allow the Fund and the Portfolio to continue to benefit from any economies of scale in the future.

Liquidity Risk Management Program

The Fund has implemented a written liquidity risk management program (Program) and related procedures to manage its liquidity in accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (Liquidity Rule). The Liquidity Rule defines “liquidity risk” as the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of the remaining investors’ interests in the fund. The Fund’s Board of Trustees/Directors has designated the investment adviser to serve as the administrator of the Program and the related procedures. The administrator has established a Liquidity Risk Management Oversight Committee (Committee) to perform the functions necessary to administer the Program. As part of the Program, the administrator is responsible for identifying illiquid investments and categorizing the relative liquidity of the Fund’s investments in accordance with the Liquidity Rule. Under the Program, the administrator assesses, manages, and periodically reviews the Fund’s liquidity risk, and is responsible for making certain reports to the Fund’s Board of Trustees/Directors and the Securities and Exchange Commission (SEC) regarding the liquidity of the Fund’s investments, and to notify the Board of Trustees/Directors and the SEC of certain liquidity events specified in the Liquidity Rule. The liquidity of the Fund’s portfolio investments is determined based on a number of factors including, but not limited to, relevant market, trading and investment-specific considerations under the Program.

At a meeting of the Fund’s Board of Trustees/Directors, the Committee provided a written report to the Fund’s Board of Trustees/Directors pertaining to the operation, adequacy, and effectiveness of implementation of the Program, as well as the operation of the highly liquid investment minimum (if applicable) for the period December 1, 2018 through December 31, 2019 (Review Period). The Program operated effectively during the Review Period, supporting the administrator’s ability to assess, manage and monitor Fund liquidity risk, including during periods of market volatility and net redemptions. During the Review Period, the Fund met redemption requests on a timely basis.

There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.
