Context

• Sell-to-cover transactions are routine steps to satisfy tax obligations when restricted stock or RSUs vest and generally do not signal a change in an insider’s view of the company.
• For retail investors, purchases or voluntary insider buys tend to be more informative about insider sentiment than mandatory tax-withholding sales.
