Share prices are adjusted for splits and other share changes, so the high and the last price compare like for like; the peak market value is as it was on the day. The return covers the trading days in our data only: it does not include what holders received, or lost, after the last trade (a merger payout, a bankruptcy), and it does not reach back before 2007.
