This was followed by equally downbeat results from Wells Fargo ( WFC ), who blamed falling oil prices and its impact on energy companies for a 6% decline in Q1 profit. U.S. stock futures were set to open on Thursday nearly unchanged, though slightly more defensive, after Bank of American ( BAC ) reported lower Q1 profits, and Wall Street braced for the March consumer price index. The U.S.'s second largest bank reported a 13% drop in net income as a result of low interest rates and declining trading revenue.
