Major Hedge Funds Shift Portfolios Toward Tech and Transport Giants in Q1 2026

Wall Street's heavyweight investors executed significant portfolio rotations during the first quarter of 2026, with concentrated bets on cloud computing, artificial intelligence, and mobility platforms. Pershing Square's Bill Ackman initiated a fresh position in Microsoft Corporation while liquidating his Alphabet stake, signaling a strategic pivot between two tech behemoths.

Berkshire Hathaway dramatically increased its Alphabet exposure, tripling its position to 58 million shares worth approximately $16.6 billion. The Omaha-based conglomerate surprised markets by re-entering the airline sector through a $2.65–$3 billion stake in Delta Air Lines, marking a notable reversal from Warren Buffett's 2020 exit from airline investments.

E-commerce giant Amazon saw divergent positioning, with Appaloosa and Pershing Square accumulating shares while Berkshire modestly trimmed its exposure. The mobility sector attracted capital as both Appaloosa and Pershing Square added to Uber positions, building a combined exposure exceeding half a billion dollars.
