I'm a dangerous man
After I first left Schwab to go back to business school in June 1994, the stock performed exceptionally well. In fact, until October 1999, when I rejoined the firm after a few years in consulting, SCH was the second highest performing stock in the entire market behind Microsoft.
Of course, over the next five years, when I left again in October 2004, the stock nosedived. The highest price the stock ever was during that period was literally the day I started and had my stock options priced. Not so great.
Since I did leave, the stock has definitely performed okay. Or so I had thought - in fact, it's performed VERY well - up more than 100% in those two years. The S&P and NASDAQ are up, in contrast, about one tenth as much - around 10% or so each.
So, if I ever do return to SCH (now SCHW) to work, it might be time to short the stock.
