Gabelli Q1 2026: A Hyper-Diversified Value Book

Gabelli Funds, the value shop founded by Mario Gabelli, reported a $14.81B U.S. equity book for the quarter ended March 31, 2026 (Form 13F-HR, accession 0001140361-26-021337, filed 2026-05-14). The most striking feature is what the book lacks: concentration. Gabelli's ten largest positions account for only about 13.5% of the portfolio — meaning roughly 86% sits in a long tail of hundreds of smaller holdings. This is the opposite of a high-conviction, few-names book.

The largest position, gold miner Newmont (NEM), is just 1.75% of assets. It is followed by Nvidia (NVDA) at 1.64%, National Fuel Gas (NFG) at 1.61%, Ametek (AME) at 1.46%, and Microsoft (MSFT) at 1.34%. No name dominates — the portfolio is a sprawling collection of value, industrial, utility, and special-situation stocks.

That structure reflects Gabelli's long-standing style: "private market value with a catalyst," applied across a very wide universe, with low turnover and a heavy tilt toward old-economy and event-driven names.

Diversification as a strategy

Beyond the top five come utility NextEra Energy (NEE), Mastercard (MA), Bank of New York Mellon (BK), railcar-leasing company GATX, and Deere (DE).

The lineup is heavy on industrials, energy, utilities, and materials — sectors where Gabelli has historically hunted for undervalued businesses with identifiable catalysts like spinoffs, deals, or asset sales. With the top ten at just 13.5% of the book, no single position can dominate returns; the strategy spreads capital across a vast number of modestly sized value bets.

Low turnover, stable value

Nearly all of Gabelli's largest positions were held roughly flat, with only minor trims to Microsoft, BNY Mellon, and GATX. The reported value has been remarkably stable, holding in a tight $13B-$15B band over two years.

For a deeply diversified value book, that stability is expected — the portfolio's value tracks the broad performance of its many holdings rather than the fortunes of a few. The story here is structural: extreme diversification and a value-and-catalyst discipline, not any single quarterly move.

What it means for 13F readers

Gabelli is a clear example of diversification as an explicit strategy — the structural opposite of a concentrated activist book. With hundreds of small positions across old-economy and special-situation names, individual holdings matter far less than the overall value-and-catalyst approach.
