Bill Ackman Said High‑Quality Stocks Are Stupidly Cheap. He’s Right.

Bill Ackman’s launch of Pershing Square USA and his view that high-quality stocks are “stupidly cheap” underpins a bullish take on large-cap tech and could influence retail flows and S&P 500 performance. The article highlights Pershing Square USA’s discounted IPO-like debut (closed-end fund trading near $42) and argues that durable AI leaders remain attractively valued — Alphabet at about 28.9x trailing P/E (after ~129% past-year gains), Microsoft near 21x forward P/E, and Meta around 20x forward P/E. The piece suggests Ackman’s buying and the visibility of his fund may drive retail interest and help narrow the fund’s discount, while renewed investor attention on high-quality AI names could support further gains for the broader S&P 500.
