Context Sell-to-cover transactions are common when RSUs vest and are generally used to satisfy tax withholding; they do not necessarily indicate the insider's view on the company’s prospects. For retail investors, purchases by insiders can be more informative about confidence, while routine tax-related sales like this are administrative in nature.
