Context

• These sales were sell-to-cover transactions to satisfy tax withholding upon RSU vesting, a common insider liquidity practice and not necessarily a signal about the CEO’s view on the company’s prospects.
• Purchases generally carry more weight as a bullish signal; routine sales for tax obligations are less informative about management sentiment.
