Mario Gabelli, the chief GAMCO Investors, remains one of the most consistent voices in value investing. In recent years, his focus has sharpened on the re-industrialization of America and the unlocking of value in legacy media and sports franchises. Gabelli’s primary methodology continues to guide his firm’s $10 billion 13F portfolio, which currently favors industrial infrastructure, aerospace, and unique trophy assets. In a recent appearance on news platform CNBC, Gabelli discussed the “re-industrialization of America,” the consolidation of the media landscape, and his outlook for the US economy. Gabelli opened by discussing the “confidence factor” among US business leaders. He argued that the current economic environment was more certain than many skeptics believed. He stated that business sentiment was “materially different” today compared to late 2025 and CEOs were now more willing to commit to long-term capital expenditures because they had clearer visibility into policy and interest rate trajectories.

He balanced his optimism with a warning about the federal deficit, noting that the “math” of the government spending seven trillion while only collecting five trillion is a long-term risk that must be addressed through growth. Gabelli also discussed the bidding war for Warner Bros. Discovery assets between Paramount Skydance and other players. Gabelli reiterated his belief that the “intrinsic value of libraries”—specifically film and television catalogs—was being ignored by the public market. He noted that he was “highly likely” to tender his clients’ WBD shares to the Paramount Skydance offer, as he believed their plan for theatrical and streaming distribution provided the most significant long-term upside for shareholders. He argued that in an AI-driven distribution world, the content creators who owned the IP held all the cards.

Mario Gabelli Stock Portfolio: Top Stock Picks
10. Textron Inc. (NYSE:TXT)
GAMCO Investors’ Stake: $120 Million
Textron Inc. (NYSE:TXT) has been a consistent feature in the 13F portfolio of GAMCO Investors since the third quarter of 2012. Back then, this position comprised just under a million shares. By the third quarter of 2013, Mario Gabelli had increased this holding to more than 1.5 million shares. His fund continued to add to this stake in the coming quarters, growing it to more than 2.1 million shares by the end of the third quarter of 2014. A period of stability followed during which the fund did not make drastic changes to this stake. In late 2017 and early 2018, the fund started buying the stock again, growing the position to around 2.7 million shares. In the coming months, the GAMCO started trimming the holding. Filings for the fourth quarter of 2025 show that the fund owned close to 1.4 million shares in the firm.
Textron Inc. (NYSE:TXT) is turning heads on Wall Street due to a combination of strong performance in the aviation sector, major defense contract execution, and aggressive capital return programs. A primary driver for institutional interest is Textron Aviation. Recent data indicates this division has seen accelerating growth, with sales climbing as much as 36% in late 2025. The strong demand for business jets and the FAA certification of new models like the Beechcraft Denali provide a clear revenue runway. Hedge funds often favor the aviation segment for its ability to generate recurring revenue through parts and maintenance, which offers better margins than one-off sales.
