Oslo Børs looked set for weak gains as the new session approached. Oil worked in the market's favor while the exchange sat closed, with prices rising more than 1.6 percent since Monday afternoon. Brent spot, the benchmark for North Sea crude, traded near 110 dollars a barrel shortly before the opening. Aker shares climbed on rumors of pending agreements, though nothing had been made official. Deal chatter is enough to move a stock, at least until the rumor gets confirmed or dies. The opening tone therefore depends on whether the crude rally and the Aker talk both hold up. Traders had little else to chew on ahead of the bell.
