U.S. stock futures are mixed as forecasts at companies including Boeing Co. and Yahoo! Inc. (YHOO) trailed analysts’ projections and Apple (AAPL) exceeded most analysts' wildest fantasies in FQ1 as its net income rocketed 118% to $13.06B, or $13.87 a share, making it one of the most profitable quarters ever for any U.S. company.

AAPL’ revenue surged 73% to $46.3B as Apple sold 37M iPhones, 15.4M iPads, and 5.2M Macs. Apple said earnings could have been higher if it could have kept up with demand, and forecast FQ2 figures that top Street estimates. Apple now has $97.6B in cash and could once again be the U.S.'s most valuable company.
