| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? For the twelve months ended November 30, 2024, Class A shares of ClearBridge Large Cap Growth Fund returned 35.39%. The Fund compares its performance to the Russell 1000 Growth Index, which returned 38.04% for the same period. PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Netflix, a popular video streaming service within the communication services sector, stock was boosted by results that consistently outperformed expectations due to strong subscriber growth, success in its enforcement of paid sharing of subscriptions, continued growth in its advertising business and improved new programming. ↑ Eaton, a diversified power company within the industrials sector whose products enable the electrification of the power grid, saw its shares rise as artificial intelligence drove demand for electricity at data centers that are equipped for high electricity use cases. ↑ Intuitive Surgical, a maker of robotic instruments for surgery within the health care sector, had a well-received launch of an innovative new daVinci robot along with improved sales and earnings growth that lifted its stock. Top detractors from performance: ↓ Estee Lauder, a cosmetics and skin care products manufacturer within the consumer staples sector, stock fell sharply due to continued execution challenges, headwinds from China, inventory clearance and share loss within the U.S. The Fund exited the position amid low visibility to profit recovery and executive leadership turnover. ↓ Adobe, a design and marketing software company within the information technology sector, as the software industry had been hurt by a weak economic backdrop, especially among smaller customers, as well as reduced contract renewals. The company struggled due to disappointing results over the period. ↓ Thermo Fisher Scientific, a provider of tools and instruments for medical, scientific and industrial applications within the health care sector, as its revenue growth rates had been negatively affected by weaker biotech spending, R&D rationalization efforts among larger pharmaceutical companies and a weak spending environment in China. | |
