Open-market purchases and sales from Forms 4 (SEC), one row per trade - grants, option exercises, tax withholding and gifts left out; a trade filed by several owners (a fund and its partner on the board) counted once; purchases in an IPO or a financing kept apart from open-market buys; sales under a 10b5-1 plan marked as planned. What happened next is measured from the first trading day after the filing. These are historical data points, not buy or sell signals.
