Traders didn't have a lot to get excited about after the close Friday, until WorldCom ( WCOM) upset the rather quiet mood with a revenue warning.

Following the close of regular trading, WorldCom lowered its revenue guidance for 2002 and cut its capital spending plan. The stock was lately down 13.5% to $5.17, making it the biggest percentage loser on the Instinet platform after the close.

Credit card issuer Metris ( MXT) was ticking up 0.1% to $13.13, and a handful of other non-tech companies were making their way onto the volume leader board. Tyco International ( TYC) was active, but unchanged at $29.89.
