Monitor for follow-up selling or commentary around earnings or capital raises. A C-suite sale combined with a major investor exit may signal profit-taking after a run-up or concerns about valuation. Watch for Form 13F changes or short interest shifts.

- Magnetar Financial LLC sold 179,250 shares at $40 per share for $7,170,000 in an open-market transaction.

- Total open-market selling: $8,262,470 over 7 days.
- Total insider selling represents ~0.019% of $43.6B market cap — modest in relative terms but concentrated and material due to C-suite participation and large single trade.
Financial Impact

Risk Factors
- Insider selling may indicate lack of confidence in near-term valuation or upcoming volatility.
- Magnetar's large sale could reflect a strategic exit, increasing downward pressure on shares if more selling follows.
