Let's see if we have this straight: Net stocks rallied Tuesday despite strong economic data, but today the sector was down, despite a friendly economic report?

Well, it's not quite that simple, though that was how it appeared today. After a quick start after a somewhat-benign

Consumer Price Index

report, Net stocks slipped along with the

Nasdaq

. Disappointment with

Oracle's

(ORCL) - Get Report

earnings, along with a setback in Treasury prices due to dollar weakness, contributed to the setback. Oracle was off 3 1/16, or 7%, at 42 3/8 after meeting, but not exceeding, earnings

estimates Tuesday.

TheStreet.com Internet Sector

index was down 7.89, or 1.3%, at 617.67. The DOT reached a high of 635.52 early in the session before sliding back.

Jim Benning, stock trader with

BT Brokerage

, said the market has just had a negative tone lately, and traders are selling into any strength. He said there are still concerns that the

Federal Reserve

will raise interest rates when it meets in October, thus offsetting all three cuts in interest rates from last year.

"It seems every time there's a good piece of news, it's an opportunity to sell rather than buy, and any gains fade out as the day goes on," he said.

Benning said buying on dips remains "a valid strategy." He said the market is heading into a period when it typically does not do well, but once October is over, he expects a good flow of money to be put into the market as the end of the year draws closer.

Price action in the Net bellwethers told today's story well.
