David Guerrero first gained exposure to the stock market during the dot-com heyday. While working for an online press release firm that published earnings reports, he heard water-cooler chatter about the money some of the salespeople were making trading Internet stocks.
In early March 2000, he opened up his first brokerage account with $3,500 and bought stocks that were well off their 52-week highs.
“I felt like I was getting a really good price,” he remembers. However, by the middle of March his account was half-gone and by the end of the month it was totally wiped out.
