Summary
Bill Ackman, chief executive of Pershing Square, pushed back against comparisons between today's market and the "roaring twenties" that preceded the Great Depression, according to a Seeking Alpha report published November 3, 2026. In an interview with CNBC, Ackman argued that stock valuations remain supported by fundamentals, and he said earnings expectations have supported current price levels. The available text cuts off before he elaborates on those expectations.

The headline also attributes to Ackman the view that AI development cannot be slowed. The available coverage does not provide his specific arguments on AI spending, investment levels, or timelines. A TradingView version of the same story carries an identical headline but no additional content.

Because the source material is limited, further detail on valuation metrics, earnings figures, or specific holdings cannot be confirmed from the reporting available. Readers seeking the full remarks should refer to the complete CNBC interview or the original Seeking Alpha article.
