Tonight's traders remained cautious on tech in the wake of

Cisco Systems's

(CSCO) - Get Report

recent

earnings confession.

Decliners outpaced advancers in both extended trading platforms, and Cisco continued its slide, lately losing 0.3% to $19.07 on Instinet and 0.2% to $19.09 on Island. Overall volume was light as investors took a breather from today's

moderate selloff, but some after-the-bell news inspired tonight's activity.

Go Green!

Storage company

EMC

(EMC)

climbed 2.5% to $42.00 on

Instinet

on news it had its board authorize the repurchase of up to 50 million shares of common stock, or about 2.2% of total shares outstanding. EMC said the stock purchased under the buyback program will be available for various corporate purposes, including employee stock option and employee stock purchase plans.

Also getting a nice verdant shade was

Global Crossing

(GX)

, whose shares climbed 3.6% to $14.30 on Instinet after the telecom carrier said its quarterly loss almost doubled, but that sales rose. The stock finished at $13.80 on the

New York Stock Exchange. The company said the high cost of building its undersea and land-based communications networks offset surging sales of data services.

Nevertheless, investors weren't as bullish on rival

Worldcom

(WCOM)

, which fell 0.2% to $18.25 in tonight's extended session on Instinet.

(RTHM)

rose after the Internet access provider posted its first-quarter earnings results. Shares of the company were the most actively traded shares on

ECN, and lately gained 16.3%% to $0.50. Likewise, Internet Capital Group

(ICGE)

, an e-business holding company, rose 8.0% to $3.37 on Island after reporting its first-quarter results.
