GAMCO Investors’ Investment Philosophy

With respect to value, the company’s investment approach revolves around utilizing fundamental, bottom-up research to spot securities selling below their intrinsic value. Furthermore, the investment firm seeks to identify mispriced companies possessing healthy businesses and the presence of a catalyst that will surface value. The firm’s investment teams use a broad universe in the benchmark-agnostic approach to cover all sectors of the market and check evolving themes and value-based opportunities.

Investment Themes For 2025

The firm’s portfolio managers have shared themes that they believe will shape markets in 2025. As per Co-CIOs Chris Marangi and Kevin Dreyer, a resurgence of M&A activity will take place.  Industry consolidation is one of the favorite catalysts because it could immediately surface PMV (Private Market Value) either as a target or as a company similarly situated to a target.  Notably, increased rates and activist federal agencies depressed M&A activity over the previous 2 years. The new regime in Washington is almost certain to fuel deal activity.

The AI investment returns were largely accrued to companies that are involved in the buildout of computing infrastructure. As a result, investment returns for companies who are creating end user-facing products and services using AI technology have lagged, says John Belton, Co-Portfolio Manager of the Gabelli Growth Innovators ETF (GGRW). This dynamic is expected to reverse over the coming years with GenAI migrating from research labs to user applications and entering a new phase of commercialization.  Next, the rise in geopolitical instability continues to drive more NATO members to prioritize defense and military investments, leading to higher defense budgets throughout Europe and the U.S., says Tony Bancroft, Portfolio Manager of the Gabelli Commercial Aerospace and Defense ETF (GCAD).

Tim Winter, Co-Portfolio Manager of the Gabelli Utilities Fund (GABUX), believes that infrastructure improvements can make utilities attractive. Finally, Chris Mancini, who is the Co-Portfolio Manager of the Gabelli Gold Fund (GOLDX), believes that gold continues to offer a good opportunity for investors who are looking for a haven during uncertain times.
