Context

"Sell-to-cover" transactions are common when restricted stock units vest; they are used solely to meet tax withholding requirements and generally do not signal an exec's view on the company's prospects. Purchases or open-market acquisitions are typically more informative about insider sentiment than mandatory tax-withholding sales.
