  • • The fund maintains a highly concentrated portfolio structure with just 11 stock holdings, reflecting Ackman's conviction-driven approach to capital deployment across mega-cap technology and e-commerce equities.

Summary
Bill Ackman's Pershing Square Capital Management has executed a series of aggressive bets on major technology and e-commerce stocks, deploying billions of dollars across a concentrated portfolio of just 11 holdings. The most significant recent moves include substantial stakes in Amazon and Microsoft valued at approximately $2.4 billion each, with Amazon now ranking as the fund's second-largest position. These deployments were partially funded through the trimming of other holdings, reflecting Ackman's reallocation strategy within the equity markets.

Beyond the MSFT and AMZN positions, Pershing Square has committed $2 billion to Meta, representing approximately 10% of the fund's total capital. This investment reflects Ackman's confidence in the social media and artificial intelligence platform as CEO Mark Zuckerberg refocuses corporate strategy away from metaverse investments toward more capital-efficient initiatives. The Meta position aligns with Ackman's broader bet on large-cap technology companies positioned for sustained growth.

Notably, Ackman has also reinvested in Netflix following a previous loss in the stock, signaling renewed conviction in the streaming entertainment sector after prior drawdowns. This repositioning suggests Ackman views current valuations as attractive entry points for long-term wealth creation across the technology ecosystem. The concentrated portfolio structure—holding just 11 stocks—underscores Ackman's conviction-driven investment philosophy, where capital is deployed selectively into positions where he identifies significant value creation opportunities.

The timing of these moves follows Pershing Square's recent capital raise of over $5 billion for a new closed-end fund vehicle, providing substantial dry powder for opportunistic deployment. This capital raise, combined with the fund's current positioning, positions Ackman to capitalize on market dislocations and pursue large, conviction-based positions in mega-cap equities during periods of market volatility. The strategy reflects confidence in the long-term secular trends benefiting technology and e-commerce platforms.
