Management’s Discussion of Fund Performance
SUMMARY OF RESULTS
U.S. Growth Fund (Class A/JSGAX) returned 5.66% (excluding sales charges) for the year ended March 31, 2025. U.S. equities rose during the 12-month period, driven by high-growth, high-momentum artificial intelligence and technology stocks. Early in 2025, positive investor sentiment about domestic equities after the U.S. election reversed, reflecting concerns about the potential imposition of high tariffs, rising geopolitical tension, the potential for higher inflation, and reduced optimism about the prospects for stocks with business tied to AI.
TOP PERFORMANCE CONTRIBUTORS
Information technology | The information technology sector, a contributor to the fund’s absolute performance, was led by consumer electronics company Apple, Inc. and AI-chip developer NVIDIA Corp.
Communication services | In the communication services sector, which added to the fund’s absolute return, video-streaming service Netflix, Inc. was a standout, as the company added record new subscribers.
Financials | Within the financials sector, the fund’s top contributor on an absolute basis was Tradeweb Markets, Inc., a financial technology company.
TOP PERFORMANCE DETRACTORS
Health care | In the health care sector, ICON PLC, a clinical research organization, and managed-care company Molina Healthcare, Inc. meaningfully detracted in absolute terms.
Industrials | The industrials sector hampered results on an absolute basis, most notably due to the fund’s position in Builders FirstSource, Inc., a manufacturer and supplier of building materials.
Microsoft Corp. | Exposure to Microsoft Corp. weighed on the fund’s absolute performance, as the software maker’s shares fell sharply in late January on disappointing revenue.
The views expressed in this report are exclusively those of the portfolio management team at Wellington Management Company LLP, and are subject to change. They are not meant as investment advice.

Management’s Discussion of Fund Performance
SUMMARY OF RESULTS
U.S. Growth Fund (Class R6/JSGTX) returned 6.04% for the year ended March 31, 2025. U.S. equities rose during the 12-month period, driven by high-growth, high-momentum artificial intelligence and technology stocks. Early in 2025, positive investor sentiment about domestic equities after the U.S. election reversed, reflecting concerns about the potential imposition of high tariffs, rising geopolitical tension, the potential for higher inflation, and reduced optimism about the prospects for stocks with business tied to AI.
TOP PERFORMANCE CONTRIBUTORS
Information technology | The information technology sector, a contributor to the fund’s absolute performance, was led by consumer electronics company Apple, Inc. and AI-chip developer NVIDIA Corp.
Communication services | In the communication services sector, which added to the fund’s absolute return, video-streaming service Netflix, Inc. was a standout, as the company added record new subscribers.
Financials | Within the financials sector, the fund’s top contributor on an absolute basis was Tradeweb Markets, Inc., a financial technology company.
TOP PERFORMANCE DETRACTORS
Health care | In the health care sector, ICON PLC, a clinical research organization, and managed-care company Molina Healthcare, Inc. meaningfully detracted in absolute terms.
Industrials | The industrials sector hampered results on an absolute basis, most notably due to the fund’s position in Builders FirstSource, Inc., a manufacturer and supplier of building materials.
Microsoft Corp. | Exposure to Microsoft Corp. weighed on the fund’s absolute performance, as the software maker’s shares fell sharply in late January on disappointing revenue.
