Summary
Bill Ackman, founder and CEO of Pershing Square Capital Management, disclosed a significant portfolio restructuring in the fund's Q2 2026 13F filing, marking the hedge fund's most substantial holdings shift in several years. The overhaul introduced six new positions to a notably concentrated portfolio, which maintains only 14 total security holdings worth $19.5 billion. The high degree of portfolio concentration reflects Ackman's conviction-based investment approach and is relatively uncommon among large institutional investors.
Among the most strategically significant additions are positions in Netflix, Visa, and Mastercard. Pershing Square acquired more than $1 billion in Netflix stock, representing approximately 3.1 million shares. This entry into Netflix comes at a time when the streaming platform's valuation has contracted considerably—shares have declined 32% over the prior twelve months as of late August 2026. At a current price-to-earnings ratio of 26, Netflix trades materially below its five-year average P/E of 36, suggesting Ackman identified a valuation opportunity in the widely-held but currently out-of-favor name.
The underlying investment thesis driving these new positions centers on a combination of valuation discipline and quality. Ackman typically pursues a strategy of acquiring market-leading, structurally advantaged businesses at reasonable or depressed valuations, then maintaining conviction through holding periods. Visa and Mastercard, as dominant payment processors, alongside Netflix as the leading streaming entertainment platform, align with his preference for businesses with durable competitive advantages and secular growth tailwinds, particularly when trading at attractive entry points.
Pershing Square's long-term track record supports investor attention to these moves. Since inception in January 2004, the fund has generated cumulative net gains of 2,644% through the end of 2025, translating to an average annual return of approximately 16%—substantially outperforming the broader equity market's 11% average return over the same period. This performance differential has established Ackman as one of the more closely watched hedge fund managers among institutional investors and family offices. Additional new holdings announced alongside Netflix, Visa, and Mastercard include positions in Alcon and Intercontinental Hotels, further diversifying the portfolio's sector exposure while maintaining the concentrated, high-conviction positioning characteristic of Pershing Square's investment philosophy.
