Hawk, The Barron's article will have little if any effect, IMO. When Barron's reports something new and meaningful, it moves markets. Unfortunately this article lacks substance. As Greg said it is merely "noise." It warms over the opinions of analyst Poyner:Poyner has had a "hold" rating on Dell for more than a year, and so he missed out on much of the stock's increase. But he still believes the move to lower-cost computers and an increasing emphasis on service will start to hurt Dell's bottom line. TRANSLATION: In 1998 year to date, Dell rose 100%. In 1997 Dell was the number-one-performing stock in the S&P 500. During most of that time Poyner was a bear. Yet the Barron's reporter thinks we should nevertheless listen to Poyner, who has been consistently and disastrously wrong? Good show, Barron's. Even more dubious is Barron's use of a 200 day moving average to suggest Dell is overpriced. There is no scientific evidence whatever to support this method of forecasting stock prices. The folks who espouse this and other forms of "technical analysis" are a thoroughly discredited minority on Wall Street. Most of them make their money not by professional money management but by selling their opinions to gullible investors. They pretend that what they do is science. As Paul Levy has pointed out, they often use the language and trappings of statistics, but they don't use the methodology which is hypothesis testing. There are many good books on the failings of TA. Most of the professional literature has concluded that TA falls in the same category as alchemy. Many studies have concluded that stocks prices follow a random walk (or, to be more precise, a random walk with upward drift). If this conclusion is correct, it would not be possible to forecast stock prices using a moving average of past prices, or for that matter any other function of past prices. In other words the past history of stock prices can't be used to predict the future in any meaningful way. It's too bad the Barron's reporter seemed blissfully unaware that any such body of knowledge even exists.
