Alpha Buying: 4 Falling Knives Insiders Are Buying

Sep 10, 2026, 4:16 PM UTC · Primary ticker $BSX

This filing highlights significant insider buying in four companies (Boston Scientific, Cardinal Infrastructure Group, GBank Financial Holdings, and Amrize) whose stock prices have fallen substantially. The author interprets these purchases as a strong signal that insiders believe their companies are undervalued and poised for recovery, despite current market skepticism.

The filing details substantial insider purchases at Boston Scientific, Cardinal Infrastructure Group, GBank Financial Holdings, and Amrize, all of which have experienced significant stock price declines. This matters because insider buying, especially by multiple executives and in meaningful amounts, is historically a strong indicator of management's belief in future stock appreciation, particularly for undervalued companies. This could signal a potential short-term bottom and long-term recovery for these stocks, affecting current shareholders and potential investors. The key opportunity for traders lies in identifying whether these insider purchases precede a turnaround, while the risk is that insiders, despite their knowledge, can still be wrong or early.
