Context
Sell-to-cover transactions following RSU vesting are common and generally represent a tax-related liquidity event rather than a directional bet on the company’s stock. For retail investors, purchases by insiders can be more informative as a signal of confidence; routine tax-related sales like this are typically neutral from a sentiment standpoint.
