SAN FRANCISCO -- Profit-taking late in the day left Internet stocks mixed, with price action in Yahoo! (YHOO) representative of the up-and-down trade seen in the sector.

TheStreet.com Internet Sector

index ended the session up 1 point, or 0.2%, at 665.30, far from its session high of 689.16. Gains in both Yahoo! and

America Online

(AOL)

set a positive tone for the session early, but Yahoo! sold off in the final hour of trading and contributed to the late weakness in the sector.

Yahoo! traded to a high of 189 1/4 in advance of Wednesday's earnings report. But the Net portal gave back its gains and finished the session down 3, or 2%, at 175 1/8. Investors may have been looking to get a jump on the selloff that typically takes place after Yahoo! reports earnings. Yahoo! has reached highs just before its last two earnings reports in April and January, before selling off despite besting estimates both times. It is expected to report earnings of 8 cents a share, according to

(EXDS)

. Exodus has been seen as a prime buyout candidate since

Metromedia Fiber Network

(MFNX)

agreed to buy Internet service provider

last month. Exodus closed up 11 3/4, or 10%, at 130 1/2.

"I think somebody's kicking the tires on this thing," said Steve Harmon, senior investment analyst with

Internet.com

. Harmon said the Baby Bells, international telecommunications companies or

IBM

(IBM) - Get Report

would be potential buyers for Exodus. "It's really their business

telecommunication companies and the future of communications. They're in the business of storing and moving data."
