If you had invested $1000 at the beginning of the bull market in 1988 and got out right before the dot-com bubble burst in 2000, your portfolio would have been worth approximately $14,500. The bull market of the late 1980s and early 1990s was one of the longest and most profitable in U.S. history, with stock prices more than tripling during this period. Had you stayed invested in the market, your portfolio could have been worth significantly more, but the dot-com bubble burst in 2000, leading to a recession that saw stock prices fall from the highs of the bull market.
