Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the U.S. Federal Reserve (the "Fed") and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of AI-related tech and semiconductor companies. And markets continued to be dominated by the so-called "Magnificent Seven", consisting of Alphabet Inc, Amazon.com Inc, Apple Inc, Meta Platforms Inc, Microsoft Corp, NVIDIA Corp and Tesla Inc. Compared to the Russell 1000 Index, which returned 23.88% during the reporting period, the Fund significantly underperformed. The Fund's focus on higher yielding dividend stocks had significant overlap with value stocks, which underperformed growth securities which in turn captured the outperformance of AI-related tech and semiconductor companies, as well as the Magnificent Seven. Because of this, value stocks significantly underperformed. The Fund also tilts towards stocks characterized by the quality and size factors, but while the quality factor slightly outperformed, the size factor underperformed, and the net impact to the Fund was negative.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? During the reporting period, Energy was the best performing sector within the portfolio, followed by Financials and Information Technology. At the same time, Consumer Staples was the worst performing sector, followed by Communication Services and Health Care. From a single stock perspective, NVDIA was the best performing security in the portfolio, followed by Williams-Sonoma Inc and Constellation Energy. The worst performing security was Hertz Global, followed by New York Community Bancorp and ViaSat. When we analyze the performance of the Russell 1000 Momentum Focus Index relative to the market capitalization weighted index, such as the Russell 1000 Index, we can see that the Factor Index underperformed the Russell 1000 over the reporting period. Most of the underperformance can be attributed to under-weight to Information Technology stocks, followed by Communication Services and Industrials. Under-weights to NVDIA Corp, Meta Platforms and Amazon Inc were the main relative detractors. On the positive side, over-weights to Apple Inc and NRG Energy Inc added relative value, while under-weight to Tesla also contributed positively.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? Management fees, cash drag, and cumulative effects of security mis-weights contributed to the difference between the Fund’s performance and that of the Index and were primary drivers of Fund performance during the period. During the reporting period, the Energy sector was the best performing sector for this strategy, followed by Financials and Industrials. At the same time, Consumer Staples was the worst performing sector, followed by Communication Services and Utilities. From a single stock perspective, Williams-Sonoma was the best performing security in the Index, followed by NRG Energy Inc and SL Green Realty Corp. Hertz Global was the worst performing security in the Index, followed by New York Community Bancorp, Inc. and Leggett & Platt Inc. When we analyze the performance for this Strategy relative to a market capitalization weighted index, such as the Russell 1000 Index, we can see that during the reporting period, the Russell 1000 Low Volatility Focus Index trailed the Russell 1000 Index. Most of this underperformance can be explained by the Factor index’s underweight to Information Security stocks, followed by Communication Services and overweight to the Consumer Staples sector. From a single security perspective, the Factor Index did not hold NVDIA Corp., Meta Platforms and Amazon Inc, which are the top 3 detractors from relative performance. Simultaneously, not including Apple Inc, Tesla Inc and Johnson & Johnson contributed positively.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the Fed and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of AI-related tech and semiconductor companies. And markets continued to be dominated by the so-called "Magnificent Seven", consisting of Alphabet Inc, Amazon.com Inc, Apple Inc, Meta Platforms Inc, Microsoft Corp, NVIDIA Corp and Tesla Inc. Compared to the performance of the S&P 500, which returned 24.56% for the reporting period, the Fund significantly underperformed. The Fund's tilt towards value stocks substantially underperformed growth stocks whose returns were characterized by the high returns of the Magnificent Seven and AI-related tech and semiconductor stocks. As a result, the Fund's value tilt strategy was unable to generate competitive returns for the reporting period.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the Fed and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of AI-related tech and semiconductor companies. And markets continued to be dominated by the so-called "Magnificent Seven", consisting of Alphabet Inc, Amazon.com Inc, Apple Inc, Meta Platforms Inc, Microsoft Corp, NVIDIA Corp and Tesla Inc. Compared to the performance of the S&P 500, which returned 24.56% for the reporting period, the Fund significantly outperformed. The Fund's tilt towards high momentum securities captured the returns of the many high-performing AI-related tech and semiconductor stocks. As a result, the Fund's momentum tilt strategy successfully produced strong relative returns for the reporting period.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? As 4Q23 began, markets seemed to teeter on each economic release, and the heightened sensitivity combined with the geopolitical uncertainty introduced by the attacks of October 7th in Israel caused bond market yields to spike and markets to sell-off in October. Concern about rate hikes turned into speculation about rate cuts and the possibility that the Fed might actually orchestrate an economic soft landing. This, combined with continued enthusiasm for semiconductor companies that investors believed would drive the impending A.I. revolution, induced markets to resume their gains in the last two months of the calendar year. As markets wrestled with the Fed’s slight bias towards hawkishness, A.I.-related semiconductor stocks continued to surge, revealing the investor belief that A.I. represented an enormous secular growth opportunity that transcended concerns about the macroeconomy. These and the Magnificent Seven once again pulled the market up with them into the end of the Reporting Period, ultimately producing strong net gains for the year.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the Fed and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And markets continued to be dominated by the so-called "Magnificent Seven", consisting of Alphabet Inc, Amazon.com Inc, Apple Inc, Meta Platforms Inc, Microsoft Corp, NVIDIA Corp and Tesla Inc. Compared to the Russell 2000 Index, which gained 10.06% in the reporting period, the Fund slightly underperformed. Small cap securities that exhibited low volatility characteristics slightly underperformed the broader small cap market. Because the Fund's strategy targeted these securities, relative performance was negatively impacted.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. Economic indicators from the U.S. remained relatively strong over the Q3 2023. While investors began the quarter with hopes that the rate hikes would soon end and cuts would begin, that probability ended by the end of the quarter. U.S. stocks rallied in the Q4 2023, supported by prospects of rate cuts in 2024. October’s economic data had spooked investors. However, things took a turn by November – inflation softened and the U.S. Federal Reserve (“the Fed”) Chair’s supportive comments shored up investor sentiment. U.S. equities rallied for a second straight quarter in the Q1 2024. At 10.4%, the S&P 500 Index posted its biggest first-quarter gain since 2019 and its fifth gain in the last six quarters. The AI theme was a key tailwinds in the Q1 2024. The biggest area of concern during the quarter revolved around sticky core services inflation even as the U.S. economy remained resilient. U.S. equity indices were mixed in the Q2 2024, with a tough start to the quarter in April. The momentum changed in the middle of the month due to a strong jobs report, ending up positive in May and June. The Fed held the interest rates steady and struck a hawkish tone in June, maintaining the current policy rate and projecting only one rate cut in 2024.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the U.S. Federal Reserve (the “Fed”) and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of AI-related tech and semiconductor companies. AI-related semiconductor stocks continued to surge, revealing the investor belief that AI represented an enormous secular growth opportunity that transcended concerns about the macroeconomy. While AI stocks and the Magnificent Seven drove broader market returns higher, many companies outside of this space fell behind, including those specializing in smart mobility. The Fund did not invest in derivatives during the reporting period

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. Economic indicators from the U.S. remained relatively strong over the Q3 2023. U.S. stocks rallied in the Q4 2023, supported by prospects of rate cuts in 2024. U.S. equities rallied for a second straight quarter in the Q1 2024. U.S. equity indices were mixed in the Q2 2024, with a tough start to the quarter in April. The momentum changed in the middle of the month due to a strong jobs report, ending up positive in May and June. The U.S. Federal Reserve (“the Fed”), held the interest rates steady in June, maintaining the current policy rate and projecting only one rate cut in 2024. In terms of Future Security Index, the period started out very eventful on the cybersecurity front as ransomware attacks were carried out in September on Caesars Entertainment and MGM Resorts, among other well-known corporations. The continuous adoption of cloud, hybrid workforce, rapid emergence and use of AI has made security risk management a top priority. The Fund did not invest in derivatives during the reporting period.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. Economic indicators from the U.S. remained relatively strong over the Q3 2023. While investors began the quarter with hopes that the rate hikes would soon end and cuts would begin, that probability ended by the end of the quarter. U.S. stocks rallied in the Q4 2023, supported by prospects of rate cuts in 2024. October’s economic data had spooked investors. However, things took a turn by November – inflation softened and the U.S. Federal Reserve (the “Fed”) Chair’s supportive comments shored up investor sentiment. U.S. equities rallied for a second straight quarter in the Q1 2024. At 10.4%, the S&P 500 Index posted its biggest first-quarter gain since 2019 and its fifth gain in the last six quarters. The AI theme was a key tailwinds in the Q1 2024. The biggest area of concern during the quarter revolved around sticky core services inflation even as the U.S. economy remained resilient. U.S. equity indices were mixed in the Q2 2024, with a tough start to the quarter in April. The momentum changed in the middle of the month due to a strong jobs report, ending up positive in May and June. The Fed held the interest rates steady and struck a hawkish tone in June, maintaining the current policy rate and projecting only one rate cut in 2024.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the U.S. Federal Reserve (the “Fed”) and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of AI-related tech and semiconductor companies. AI-related semiconductor stocks continued to surge, revealing the investor belief that AI represented an enormous secular growth opportunity that transcended concerns about the macroeconomy. While AI stocks and the Magnificent Seven drove broader market returns higher, many companies outside of this space fell behind, including those specializing in clean power.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. Economic indicators from the U.S. remained relatively strong over the Q3 2023. While investors began the quarter with hopes that the rate hikes would soon end and cuts would begin, that probability ended by the end of the quarter. U.S. stocks rallied in Q4 2023, supported by prospects of rate cuts in 2024. U.S. equities rallied for a second straight quarter in Q1 2024. The AI theme was a key tailwinds in Q1 2024. The biggest area of concern during the quarter revolved around sticky core services inflation even as the U.S. economy remained resilient. U.S. equity indices were mixed in Q2 2024, with a tough start to the quarter in April. The momentum changed in the middle of the month due to a strong jobs report, ending up positive in May and June. Despite the strength in AI and increased focus on robotics, Final Frontiers Index overall performance was muted for the reporting period due to concerns over aerospace struggles and manufacturing delays.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the U.S. Federal Reserve (the “Fed”) and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of AI-related tech and semiconductor companies. The reporting period began just after the so-called “Magnificent Seven” stocks began dominating U.S. market returns, thereby earning their catchy moniker. But these seven tech mega-caps—Alphabet Inc, Amazon.com Inc, Apple Inc, Meta Platforms Inc, Microsoft Corp, NVIDIA Corp. and Tesla Inc.—lost some of their shine when in aggregate, they alongside the rest of the market pulled back in the third quarter of 2023. Uncertainty surrounding economic growth, inflation and the Fed’s stance on the direction of rates rattled some investors who feared that the Fed would keep rates higher for longer, cutting into economic growth more than was necessary to curtail inflation. U.S. markets continued to be strong in 2024 as Meta, NVIDIA and Amazon.com had near-record gains in February after strong earnings numbers.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? Management fees, cash drag, and cumulative effects of security mis-weights contributed to the difference between the Fund’s performance and that of the Index and were primary drivers of Fund performance during the period. Over the past year, the S&P 600 ESG Index has outperformed the S&P 600 Index by 2.81%. Most of this outperformance was explained by overweights to Information Technology securities and Industrials. During the Reported Period Financials, Industrials and Materials were the best performing sectors in the fund, while Utilities, Communication Services and Health Care were the bottom performers. From a single security level contribution, Abercrombie and Fitch was the best performing stock in the portfolio, followed by Powell Industries and Hibbett Inc. Forward Air Corporation was the worst performing security, followed by TTEC Holdings and iRobot Corp. The fund did not invest in any derivative during the reported period.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. markets closed the calendar year of 2023 with a rally, supported by prospects of rate cuts in 2024 and encouraging Q3 2023 earnings. This rally continued in to the first calendar quarter of 2024. Communications services fared the best with strong returns by Meta, Walt Disney and Netflix. Information Technology was also a stand out with a strong rally in Nvidia Corp. The AI theme was one of the key tailwinds in Q1 and Q2 of 2024, helping to drive select big tech outperformance. US.. equity markets moved higher in May and June of 2024, posting strong returns as corporate earnings results outweighed fears that the U.S. Federal Reserve (the “Fed”) might delay rate cuts until later in 2024.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the Fed and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. A.I.-related semiconductor stocks continued to surge, revealing the investor belief that A.I. represented an enormous secular growth opportunity that transcended concerns about the macroeconomy. These and the Magnificent Seven once again pulled the market up with them into the end of the reporting period, ultimately producing strong net gains for the year. The Fund used equity index futures in order to equitize cash and accruals during the reporting period. The Fund’s use of futures helped the Fund track the Index.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? Performance was weak during the 1st quarter of the fiscal year as challenging inflation prints contributed to reduced optimism regarding the timing and magnitude of Federal Reserve rate cuts. These rate concerns combined with signs that growth was slowing led to the market’s decline during the 1st quarter. Conversely, the 2nd quarter of the fiscal year was marked by a dramatic change in returns as the S&P 500 gained over 11% during this period. This was driven by better growth, incremental progress on the inflation front and AI related optimism. The second half of the fiscal year continued the strong market returns from the second quarter. Though there were concerns regarding the stickiness of inflation during the early part of the period by the end of the period the market was convinced that real inflation progress was occurring especially in regard to the last mile of inflation. There were other signs most notably in the labor market that perhaps the Federal Reserve was going to pull of the challenging act of a soft landing. This combined with continued earnings growth and even increasing levels of AI related optimism led to the market appreciating by over 15% over the final 2 quarters of the fiscal year.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact on the Fed regarding interest rate decisions. The first quarter of the reporting period started with Investors hope of Fed rate cuts based on positive economic indicators, but those hopes waned quickly as the S&P 600 Index ending up losing 5% in the quarter. In the fourth quarter of 2023, small cap Index gained 15% on the back of growing anticipation of potential policy easing and prospects of rate cuts in 2024. The small cap Index picked up another 2.5% in the following quarter based on macroeconomic data that continued to highlight a strong US economy. In the second quarter of 2024, the Fed held the interest rates steady and struck a hawkish tone in June that resulted in a decline of 3.1% of the S&P 600 Index for the second quarter of 2024. On an individual security level, the top positive contributors to the Fund’s performance on an absolute basis during the reporting period were PHINIA Inc., e.l.f. Beauty, and Onto Innovation Inc. The top negative contributors to the Fund’s performance on an absolute basis during the reporting period were V.F. Corporation, Worthington Steel Inc., and Organon & Co.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. Economic indicators from the U.S. remained relatively strong over the Q3 2023. While investors began the quarter with hopes that the rate hikes would soon end and cuts would begin, that probability ended by the end of the quarter. U.S. stocks rallied in Q4 2023, supported by prospects of rate cuts in 2024. October’s economic data had spooked investors. However, things took a turn by November – inflation softened and the U.S. Federal Reserve (the “Fed”) Chair’s supportive comments shored up investor sentiment. U.S. equities rallied for a second straight quarter in Q1 2024. At 10.4%, the S&P 500 index posted its biggest first-quarter gain since 2019 and its fifth gain in the last six quarters. The AI theme was a key tailwind in Q1 2024. The biggest area of concern during the quarter revolved around sticky core services inflation even as the U.S. economy remained resilient. U.S. equity indices were mixed in Q2 2024, with a tough start to the quarter in April. The momentum changed in the middle of the month due to a strong jobs report, ending up positive in May and June. The Fed held the interest rates steady and struck a hawkish tone in June, maintaining the current policy rate and projecting only one rate cut in 2024.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. Economic indicators from the U.S. remained relatively strong over the Q3 2023. While investors began the quarter with hopes that the rate hikes would soon end and cuts would begin, that probability ended by the end of the quarter. U.S. stocks rallied in Q4 2023, supported by prospects of rate cuts in 2024. October’s economic data had spooked investors. However, things took a turn by November – inflation softened and the U.S. Federal Reserve (the “Fed”) Chair’s supportive comments shored up investor sentiment. U.S. equities rallied for a second straight quarter in Q1 2024. At 10.4%, the S&P 500 index posted its biggest first-quarter gain since 2019 and its fifth gain in the last six quarters. The AI theme was a key tailwind in Q1 2024. The biggest area of concern during the quarter revolved around sticky core services inflation even as the U.S. economy remained resilient. U.S. equity indices were mixed in Q2 2024, with a tough start to the quarter in April. The momentum changed in the middle of the month due to a strong jobs report, ending up positive in May and June. The Fed held the interest rates steady and struck a hawkish tone in June, maintaining the current policy rate and projecting only one rate cut in 2024.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the Fed and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And markets continued to be dominated by the so-called “Magnificent Seven”, consisting of Alphabet Inc, Amazon.com Inc, Apple Inc, Meta Platforms Inc, Microsoft Corp, NVIDIA Corp and Tesla Inc. Compared with the S&P 500, which returned 24.56% during the reporting period, the Fund underperformed. Stocks with high dividend yields usually have substantial overlap with value stocks, and because these value stocks were significantly outperformed by growth stocks which comprised securities such as the A.I.-related tech and semiconductor companies, as well as the Magnificent Seven, their relative performance suffered. As a result, the Fund’s strategy underperformed the broader market during the reporting period.

Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? As 4Q23 began, markets seemed to teeter on each economic release, and the heightened sensitivity combined with the geopolitical uncertainty introduced by the attacks of October 7th in Israel caused bond market yields to spike and markets to sell-off in October. Concern about rate hikes turned into speculation about rate cuts and the possibility that the Fed might actually orchestrate an economic soft landing. This, combined with continued enthusiasm for semiconductor companies that investors believed would drive the impending A.I. revolution, induced markets to resume their gains in the last two months of the calendar year. As markets wrestled with the Fed’s slight bias towards hawkishness, A.I.-related semiconductor stocks continued to surge, revealing the investor belief that A.I. represented an enormous secular growth opportunity that transcended concerns about the macroeconomy. These and the Magnificent Seven once again pulled the market up with them into the end of the reporting period, ultimately producing strong net gains for the year.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. Economic indicators from the U.S. remained relatively strong over the Q3 2023. While investors began the quarter with hopes that the rate hikes would soon end and cuts would begin, that probability ended by the end of the quarter. U.S. stocks rallied in Q4 2023, supported by prospects of rate cuts in 2024. October’s economic data had spooked investors. However, things took a turn by November – inflation softened and the U.S. Federal Reserve (the “Fed”) Chair’s supportive comments shored up investor sentiment. U.S. equities rallied for a second straight quarter in Q1 2024. At 10.4%, the S&P 500 index posted its biggest first-quarter gain since 2019 and its fifth gain in the last six quarters. The AI theme was a key tailwind in Q1 2024. The biggest area of concern during the quarter revolved around sticky core services inflation even as the U.S. economy remained resilient. U.S. equity indices were mixed in Q2 2024, with a tough start to the quarter in April. The momentum changed in the middle of the month due to a strong jobs report, ending up positive in May and June. The Fed held the interest rates steady and struck a hawkish tone in June, maintaining the current policy rate and projecting only one rate cut in 2024.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? In Q3 2023, the S&P Bank Select Industry Index returned 3.4% for the quarter. Global economic growth remained lackluster in the third quarter, with manufacturing activities contracting for the fourth month running and services sector growth also slowing down. Business activity in the United States rose at a weaker pace, signaling broad stagnation in output amid muted demand conditions. Core inflation numbers showed a disinflationary trend, while the labor market continued to be relatively robust across key developed economies. Performance of the Fund during the reporting period was driven by strong labor markets, strong consumer spending, slowing inflation, a pause in interest rate hikes, and concerns over a recession weighted on the minds of many investors. Bank stocks rose for the fiscal year. During the reporting period, the Fund’s use of their current investment strategies did not cause the Fund’s performance to materially deviate from the manager’s expectations considering the uncertainty of the markets.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? U.S. Economic indicators from the U.S. remained relatively strong over the Q3 2023. While investors began the quarter with hopes that the rate hikes would soon end and cuts would begin, that probability ended by the end of the quarter. While larger banks posted higher returns due to rapidly rising interest rates, those higher rates had the opposite effect on regional banks. After the collapses of Silicon Valley Bank, First Republic Bank, and Signature Bank earlier in 2023, customers of local banks were still feeling uneasy about depositing their money for fear of further collapses. U.S. stocks rallied in Q4 2023, supported by prospects of rate cuts in 2024. U.S. equities rallied for a second straight quarter in Q1 2024. The Fed held the interest rates steady and struck a hawkish tone in June, maintaining the current policy rate and projecting only one rate cut in 2024. Luckily, even the hope of possible future rate cuts helped the Regional Banking Industry to finish the reporting period with strong positive returns.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period began with uncertainty around economic growth, inflation and the Fed’s stance on the direction of rates rattled some investors who feared that the Fed would keep rates higher for longer. Despite the geopolitical uncertainty introduced by the attacks of October 7th in Israel, the ongoing trickle of indicators revealed that the economy was gradually beginning to slow, and the Fed managed to soothe investors by tempering its hawkish language. Concern about rate hikes turned into speculation about rate cuts. This, combined with continued enthusiasm for semiconductor companies that investors believed would drive the impending A.I. revolution, induced markets to resume their gains.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? After gaining close to 22% during the prior fiscal year, the Aerospace & Defense Industry continued that trajectory during this most recent fiscal year by adding another 16.21%. Unlike the prior period, however, the Industry lagged the S&P 500 Index (+24.56%) this time around. The more than 8% deficit is even more noteworthy given that the Industry actually beat the broader index by close to 10% during the second fiscal quarter – the only quarter of outperformance throughout the fiscal period. The quarterly outperformance stemmed from business aviation usage hitting 20% above pre-COVID levels (according to data tracker WingX Advance) and the passing of the National Defense Authorization Act (NDAA) that will allocate $886 billion to national security in 2024. Overall, defense stocks paralleled the S&P 500 for the most part while Aerospace stocks played the role of laggard. This was led by Virgin Galactic (-89.14%) who announced the discontinuance of their Unity spacecraft venture. Boeing (-12.63%) also had an unfortunate year that not only saw manufacturing problems interrupting production of both their 737 Max and 787 Dreamliner, but also in-flight malfunctions, whistleblowing, and regulatory scrutiny.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The market environment over the reporting period was largely driven by news about inflation, economic growth and the impact either would have on the Fed and other central banks with regard to interest rate decisions. Elevated mortgage rates, low existing home inventory and robust housing demand were favorable conditions for the homebuilder industry. The overall housing market still faces significant under-supply which has increased the demand for new construction.

Factors Affecting Performance [Text Block]		How did the Fund perform last year and what affected its performance? The reporting period’s market environment was largely driven by news about inflation, economic growth and the impact either would have on the Federal Reserve and other central banks with regard to interest rate decisions. Alongside this macro story was the prospect of a burgeoning artificial intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. A spike in the price of oil driven by higher demand also contributed to a complex economic situation. The higher prices were supported by increased demand for power generation, reduced production in the U.S., and supply disruptions in Norway. Robust liquified natural gas demand from Asia also boosted prices.
