Apple set for bumper quarter

Apple is set to deliver yet another bumper quarter when it announces its results tomorrow. Analysts expect stronger second-quarter revenue and profit, boosted by the easing of component shortages for the iPad caused by the Japanese tsunami, which could boost gross margins to as high as 41 per cent. The market expects revenues to rise from $15bn (£9.3bn) a year ago to between $25bn and $30bn, with earnings rising by as much as 63 per cent.
