Kaufman Bros. analyst Shaw Wu has raised his price target for Apple stock from $395 to $415, in spite of Steve Jobs taking a medical leave from the company, and the impending delivery of Q1 financial results. The figure is based on a higher gross margin prediction for the quarter, using different assumptions including new data suggesting "benign" component price trends. Wu is now calling for a margin of 37.5 percent, up from an estimate of 37.2, and Apple's own guidance of 36 percent.
