Quarterdeck Corp
3QDEK · Software & Services · NASDAQ · in our data June 11, 1991 to October 15, 1998 (7.3 years)
The first trading day in our data for Quarterdeck Corp is June 11, 1991 (its first day in our records, which may be later than its listing and is not its founding). At its peak, on December 4, 1995, the market valued it at $960 million. It ended in a collapse: the last trade was $0.44, -98.9% from its split-adjusted high. The delisting record says: merged or acquired.
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 1991.
