Earlier: Commerce One Gains as Ariba Boosts B2B

LONDON -- Business-to-business stocks could get a boost today on the back of

Ariba's

(ARBA)

narrower than expected third-quarter loss, reported yesterday.

The electronic-commerce software company said it lost 5 cents a share for the period ending June 30, before special charges, which was less than the 8-cent loss that analysts polled by

First Call/Thomson Financial

were expecting.

Other B2B stocks that could see some action today include
