Billionaire investor Bill Ackman, the founder of Pershing Square, is betting heavily on tech behemoths Meta Platforms Inc. (NASDAQ:META)and Amazon.com Inc. (NASDAQ:AMZN), identifying both companies as “durable compounders.”

According to Ackman, these dominant players possess the cash flow predictability and resilience required to anchor a highly concentrated, long-term portfolio.

Concentrated Bets on High-Quality Tech

Pershing Square focuses on a select few dominant businesses that can survive the test of time and market disruption.

Ackman, during an interview with Money News Network, said that he keeps his investment portfolio famously tight, typically holding only 12 to 15 investments at a time. Rather than chasing the latest artificial intelligence (AI) startups or attempting to make money quickly through speculative options trading, his approach centers entirely on predictability and longevity.
