Context Insider sales can be routine and have many benign reasons; they are less informative than purchases for gauging insider confidence. Note that the reported share amount includes unvested RSUs, so some of the shares involved may still be subject to restrictions. Retail investors should track patterns of multiple transactions and changes in total ownership over time rather than a single sale.
