Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Fundamental Large Cap Core Fund (Class A/TAGRX) returned 37.14% (excluding sales charges) for the year ended October 31, 2024. A resilient U.S. economy, lower interest rates, strong corporate earnings and investor enthusiasm for artificial intelligence (AI) helped propel U.S. equities sharply higher, with large-cap growth stocks taking the lead.
TOP PERFORMANCE CONTRIBUTORS
Information technology | The fund’s holdings in the sector notably boosted its absolute return. Consumer electronics leader Apple, Inc., a top holding, stood out, helped by strong demand for its smartphones and a rally in mega-cap technology stocks.
Financials | The fund’s financial holdings produced a steep gain, led by private equity company KKR & Company, Inc., which benefited from strong execution by management, growing interest in alternative investments and lower interest rates.
Consumer discretionary | This sector was another standout, thanks to positions in e-commerce giant Amazon.com, Inc. and home builder Lennar Corp.
TOP PERFORMANCE DETRACTORS
Utilities and materials | The fund’s lack of exposure to utilities and small stake in materials did little to aid performance.
Weakness from specific holdings | Notable individual detractors included a new position this period in Israel-based Mobileye Global, Inc., which makes advanced driver assist systems, as well as investments in biopharmaceuticals stock Moderna, Inc., media conglomerate Warner Brothers Discovery, Inc. and recreational vehicle company Polaris, Inc.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Fundamental Large Cap Core Fund (Class R4/JLCFX) returned 37.30% for the year ended October 31, 2024. A resilient U.S. economy, lower interest rates, strong corporate earnings and investor enthusiasm for artificial intelligence (AI) helped propel U.S. equities sharply higher, with large-cap growth stocks taking the lead.
TOP PERFORMANCE CONTRIBUTORS
Information technology | The fund’s holdings in the sector notably boosted its absolute return. Consumer electronics leader Apple, Inc., a top holding, stood out, helped by strong demand for its smartphones and a rally in mega-cap technology stocks.
Financials | The fund’s financial holdings produced a steep gain, led by private equity company KKR & Company, Inc., which benefited from strong execution by management, growing interest in alternative investments and lower interest rates.
Consumer discretionary | This sector was another standout, thanks to positions in e-commerce giant Amazon.com, Inc. and home builder Lennar Corp.
TOP PERFORMANCE DETRACTORS
Utilities and materials | The fund’s lack of exposure to utilities and small stake in materials did little to aid performance.
Weakness from specific holdings | Notable individual detractors included a new position this period in Israel-based Mobileye Global, Inc., which makes advanced driver assist systems, as well as investments in biopharmaceuticals stock Moderna, Inc., media conglomerate Warner Brothers Discovery, Inc. and recreational vehicle company Polaris, Inc.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Infrastructure Fund (Class A/JEEBX) returned 29.17% (excluding sales charges) for the year ended October 31, 2024. The world equity markets produced strong gains in the annual period, with only brief stretches of volatility interrupting what was otherwise a steady upward move. Investors displayed a robust appetite for risk at a time of positive economic growth, healthy corporate earnings, and interest-rate cuts by developed-market central banks.
TOP PERFORMANCE CONTRIBUTORS
Targa Resources Corp. | The energy infrastructure company announced better-than-expected results, reaffirmed its guidance, and reported the start of two new projects.
Vistra Corp. | The Texas-based electric utility was seen as being a key beneficiary of the growth of artificial intelligence due to the rising electricity demand from data centers. The company also reported better-than-expected results and was added to the S&P 500 Index.
Other single-stock contributors | Aena SME SA, The Williams Companies, Inc., and Constellation Energy Corp. also contributed to absolute performance.
TOP PERFORMANCE DETRACTORS
China Longyuan Power Group, Ltd. | The company missed earnings estimates due to higher operating expenses weighing on its stock price.
Nippon Telegraph & Telephone Corp. | The company reported earnings below consensus estimates and offered weaker-than-expected guidance for 2024.
Other single-stock detractors | RWE AG, Shanghai International Airport Company, Ltd., and E.ON SE also detracted from absolute performance.

SUMMARY OF RESULTS

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Small Cap Core Fund (Class A/JCCAX) returned 28.55% (excluding sales charges) for the year ended October 31, 2024. The most significant factor affecting fund performance during the period was a broad equity market rally, which was driven by decelerating inflation, steady economic growth, increased expectations for interest rate cuts by the U.S. Federal Reserve, and growing interest in artificial intelligence (AI). Small-cap stocks underperformed large-cap shares, while growth stocks outperformed value-oriented issues.
TOP PERFORMANCE CONTRIBUTORS
CommVault Systems, Inc. | The stock benefited from heightened demand for the company’s cloud-based data protection solutions amid increased ransomware attacks.
EMCOR Group, Inc. | The company, which provides electrical and mechanical services to non-residential markets, enjoyed strong demand from data centers fueled by the growth of AI.
Q2 Holdings, Inc. | The electronic banking company experienced strong subscription and booking growth, which led to higher guidance for profitability and revenue growth throughout the year.
TOP PERFORMANCE DETRACTORS
Bumble, Inc. | An unexpected reset of the online dating app company’s strategy led to weaker earnings guidance and a decline in the stock.
Savers Value Village, Inc. | The world’s largest for-profit thrift store operator reported disappointing earnings and reduced future guidance due to lower-than-expected customer demand in Canada.
WideOpenWest, Inc. | The broadband service provider experienced higher-than-expected churn within its existing customer base, which delayed anticipated expansion into new geographic areas.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Small Cap Core Fund (Class NAV) returned 29.07% for the year ended October 31, 2024. The most significant factor affecting fund performance during the period was a broad equity market rally, which was driven by decelerating inflation, steady economic growth, increased expectations for interest rate cuts by the U.S. Federal Reserve, and growing interest in artificial intelligence (AI). Small-cap stocks underperformed large-cap shares, while growth stocks outperformed value-oriented issues.
TOP PERFORMANCE CONTRIBUTORS
CommVault Systems, Inc. | The stock benefited from heightened demand for the company’s cloud-based data protection solutions amid increased ransomware attacks.
EMCOR Group, Inc. | The company, which provides electrical and mechanical services to non-residential markets, enjoyed strong demand from data centers fueled by the growth of AI.
Q2 Holdings, Inc. | The electronic banking company experienced strong subscription and booking growth, which led to higher guidance for profitability and revenue growth throughout the year.
TOP PERFORMANCE DETRACTORS
Bumble, Inc. | An unexpected reset of the online dating app company’s strategy led to weaker earnings guidance and a decline in the stock.
Savers Value Village, Inc. | The world’s largest for-profit thrift store operator reported disappointing earnings and reduced future guidance due to lower-than-expected customer demand in Canada.
WideOpenWest, Inc. | The broadband service provider experienced higher-than-expected churn within its existing customer base, which delayed anticipated expansion into new geographic areas.
