Context Sell-to-cover transactions are common when restricted stock units vest and are generally administrative in nature to meet tax obligations; they do not necessarily reflect the insider's view of the company. For retail investors, routine tax-withholding sales like this are less informative than open-market purchases or large discretionary sales.
