"WHAT DOES IT ALL MEAN? The lessons of market history are clear. Styles and fashions in investors' evaluations of securities can and often do play a critical role in the pricing of securities. The stock market at times conforms well to the castle-in-the-air theory. For this reason, the game of investing can be extremely dangerous. Another lesson that cries out for attention is that investors should be very wary of purchasing today's hot "new issue." Most initial public offerings underperform the stock market as a whole. And if you buy the new issue after it begins trading, usually at a higher price, you are even more certain to lose. Investors would be well advised to treat new issues with a healthy dose of skepticism. Certainly investors in the past have built many castles in the air with IPOs. Remember that the major sellers of the stock of IPOs are the managers of the companies themselves. They try to time their sales to coincide with a peak in the prosperity of their companies or with the height of investor enthusiasm for some current fad. In such cases, the urge to get on the bandwagon--even in high-growth industries--produced a profitless prosperity for investors."
