Unfortunately, the Wall Street Journal picked Friday to highlight the continuing attractions of technology stocks – unfortunate because a few hours after the piece appeared, technology companies were leading the market down with IBM Corp off $3.125 at $155.375 and Intel Corp down $2.625 at $125.625. They closed at $155.625 and $125.6875 respectively. The reason? Federal Reserve chairman Alan Greenspan warned late Thursday against the markets being affected by irrational exuberance. This pushed the market over the edge and sent shares tumbling. The Dow Jones Industrial Average closed down 55.16 at 6381.95 and the Nasdaq was off 12.44 points at 1287.68. The slide triggered the New York Stock Exchange’s sidecar curbs on electronic trading for the eleventh time this year.
