1. From 12/30/1991 to 1/2/1995, in three years, the Dow Jones index curve is a flat one, bounding within 1,000 points. It basically follow the principle of investment with reasonable P/E value.

2. From Jan., 1995, Dow Jones index starts its climbing. In ten months, it was up more than 1,000 poins, and went upwards rapidly since. I would say start from that time stock market value is risky with a high P/E value. The purpose is to prevent my entering the stock market. (A lesson from Chinese stock market)

3. I bought the stock on 9/23/1998 and 9/25. It was at a periodical trough. I sold the stock on 4/21/1999, that was at the average peak value. I invested not on economical condition but on the opinion that the Feds would push the market up to save its own business.
