How to Interpret $CRSP Trades
Not every insider transaction in CRISPR Therapeutics AG is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $CRSP shares on the open market. It is crucial to distinguish between scheduled sales (under Rule 10b5-1) and voluntary increases in ownership, which demonstrate management’s true conviction that the stock is undervalued.
