 Bill Ackman and his entire team just bought $311 million worth of Pershing Square USA shares in one day. Ackman himself personally invested $241 million at $49.18 per share. The CFO, CIO, president, chief compliance officer — all opened new positions. This is not an ordinary purchase. When an entire C-level team synchronously buys into company shares, it is one of the strongest signals in the market. Insiders vote with their money, and their voice is louder than any analyst report. What does this mean for investors? Pershing Square USA is Bill Ackman's closed-end fund trading on Nasdaq. The massive buying by top management indicates that the team sees serious upside. Typically, insider purchases of this scale precede a rise in stock prices. Other notable trades: S&P Global (CEO bought $1 million), Textron, GE HealthCare, Avalyn Pharma. I track insider flows in real time — it provides a picture you won't see in the news.
