Factors Affecting Performance [Text Block]

How did the Fund perform?

For the six months ended June 30, 2026, the Gabelli SRI Fund underperformed its benchmarks, the S&P 500 and  MSCI ACWI SRI Indices.  Following a turbulent start to the year, the second quarter marked a return to stability across markets, the economy, and geopolitics. The rebound was supported by improving economic fundamentals, expanding usage of AI technology, and a de-escalatory path for conflicts in the Middle East.  Value stocks widely outperformed for a second consecutive quarter. Contributors to performance included ABB Ltd, Texas Instruments, and Madison Square Garden Sports. Detractors included BellRing Brands, Sony Group, and S&P Global.
