roller coaster ride

The roller coaster ride for tech stocks grew even wilder today, but in a good, adrenaline-rush kind of way.

The news is mostly all good, with Banc of America Securities issuing a report that boosted semiconductor companies, stating that "a modest inventory build-up has eased".

That's all investors needed to know, as shares of tech stocks rose en masse, with Intel, up 4% after the Banc of America news hit the trading floor, and Apple the big winners.

The tech sector was also buoyed by a JP Morgan analyst report that upgraded Apple's profit forecasts. That shot Apple's stock up 2%.

Overall,...

This week has certainly been a roller-coaster ride for US equities. One day the DJIA is up 400 points, but the next it is down 200 points, and the next it is up 200 points again.

Thursday the DJIA finished up 261 points, but that may just portend another down day for Friday.
