In the most recent 13F, Mario Gabelli’s GAMCO Investors made a series of notable reductions across its extensive equity portfolio. Known for his deep value orientation and long-term, research-driven approach, Gabelli appears to have been selectively trimming positions where valuations have risen or catalysts have played out.
Below are the top five reductions by percentage change in common stock holdings:
- 3D Systems Corp (DDD) – ↓82.14% (Technology Hardware)
Gabelli sold 46,000 shares, leaving only 10,000. The sharp reduction reflects a substantial scale-back in exposure to the 3D printing sector, possibly signaling concerns about slowing industry adoption or profitability pressures. - Blue Owl Capital Inc (OWL) – ↓80.12% (Asset Management)
The firm trimmed 222,080 shares, retaining 55,100. The reduction suggests a reassessment of alternative asset managers amid shifting market conditions and competition for fundraising capital. - Diamondback Energy Inc (FANG) – ↓74.74% (Energy)
GAMCO sold 7,549 shares, leaving 2,551. The large cut likely reflects profit-taking after strong energy sector performance and potential repositioning within the oil and gas space. - Illinois Tool Works (ITW) – ↓58.99% (Industrials)
Gabelli trimmed 7,020 shares, holding 4,880 post-sale. The reduction in this industrial conglomerate could indicate concerns about valuation or cyclical demand moderation. - AllianceBernstein Holding LP (AB) – ↓53.89% (Financial Services)
The fund sold 38,800 shares, keeping 33,198. The move may reflect tactical portfolio management amid earnings pressures in asset management and a shift toward higher-growth opportunities elsewhere.
Overall, Gabelli’s latest activity reflects a disciplined pruning of smaller or lower-conviction positions, while maintaining focus on long-term value creation across core holdings.
Exits
Mario Gabelli’s GAMCO Investors also executed several full exits this quarter, signaling a continued streamlining of the portfolio. Among the most notable were Sandy Spring Bancorp ($6.15M), Intra-Cellular Therapies ($5.0M), and Lions Gate Entertainment ($3.6M)—all completely liquidated. Other significant departures included Patterson Companies, Beacon Roofing Supply, and Barrick Gold, each representing full divestments from prior holdings. These exits span financials, healthcare, entertainment, and industrial sectors, underscoring Gabelli’s disciplined approach to realizing gains and reallocating capital toward higher-conviction opportunities.
