Thinkorswim Group Inc

SWIM · Education · NASDAQ · in our data December 9, 2003 to June 11, 2009 (5.5 years)

The first trading day in our data for Thinkorswim Group Inc is December 9, 2003 (its first day in our records, which may be later than its listing and is not its founding). At its peak, on December 26, 2007, the market valued it at $1.2 billion. It left the market when it was bought or merged, last trading at $10.45, -42.4% from its split-adjusted high. Holders got whatever the deal paid, which is not in our price data.

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 2003.
