Tech Shares Lead Sharp Rally

Updated from 4:05 p.m. EDT

Investors went on a buying spree Monday, hoping for some solid second-quarter earnings reports.

The Dow Jones Industrial Average finished up 146.58 points, or 1.6%, at 9216.79, while the S&P 500 gained 18.80 points, or 1.9%, to 1004.50. The Nasdaq rose 57.79 points, or 3.5%, to 1721.25, eclipsing its intraday high of 1718 hit on May 21, 2002. Treasury prices were lower, with the yield on the 10-year note at 3.73%.

"Are they blowing up another bubble? Possibly," said Al Goldman, chief market strategist at A.G. Edwards. "Internals are very positive, and markets could continue moving up from here, but last time I checked, they haven't changed the rules of gravity."

On a technical note, John Bollinger, founder of BollingerBands.com, said, "Breaking the 1000 level for the S&P 500 has strong psychological significance for the market, but the key level investors should be focusing on is 1015. If it holds above that level, it will give people a great deal of confidence to come back to the market. For the Nasdaq, this has already happened at 1685, so breaking above the 1700 level today just confirms it remains the leader [among indices]."

Some big Nasdaq names had a huge day in the absence of any major company-specific news. Applied Materials(AMAT Quote) rose $1.62, or 10.1%, to $17.63; Altera(ALTR Quote) climbed $1.72, or 10%, to $18.94; Linear Technologies(LLTC Quote) advanced $2.50, or 7.5%, to $35.64; Ericsson(ERICY Quote) gained 65 cents, or 6%, to $11.33; RF Micro(RFMD Quote) rose 34 cents, or 5.7%, to $6.23; and Qualcomm(QCOM Quote) rose $2.44, or 6.5%, to $39.90.
