Sell-to-cover transactions are routine administrative sales done to satisfy tax obligations when restricted stock units vest and generally do not signal insider sentiment about the company. Purchases tend to carry more informational weight for investors; this filing documents a tax-related disposition rather than a voluntary sale.
