When an insider converts their equity derivatives into common stock.
Definition
An option exercise happens when an insider uses their right to buy shares of the company at a predetermined 'strike price', which is usually lower than the current market price. On a Form 4, this is reported with the transaction code 'M'.
Why it matters for Whale Tracking
Exercising options is often a neutral event, as it's part of executive compensation. However, what happens immediately *after* the exercise is critical. If the executive holds the new shares, it's a sign of confidence. If they immediately sell them (a 'cashless exercise'), it acts as a liquidation event.
Technical Nuance
Option excersises must be analyzed in conjunction with subsequent transactions. A standalone 'M' code doesn't indicate sentiment. However, if an insider exercises options and then files a Form 4 showing an open-market sale of those shares, it suggests they are taking profits rather than accumulating, which can be a bearish signal.

Real-World Example
"An executive exercises options to buy 1,000 shares at $50 when the stock is trading at $150. If they sell immediately, they secure the $100/share profit. Data pipelines must separate 'Code M' transactions from voluntary open-market purchases to avoid false bullish signals."
