Armstrong Holdings
ACK · Rubber & Plastics · NYSE · in our data January 2, 1968 to November 4, 2002 (34.8 years)
Our price history begins on January 2, 1968, and Armstrong Holdings was already trading then; how long before that, our data does not say. At its peak, on April 20, 1998, the market valued it at $3.6 billion. It ended in a collapse: the last trade was $1.75, -97.8% from its split-adjusted high. The delisting record says: likely failure.
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 1968.
