Apple's (AAPL) fiscal third quarter earnings are due out Tuesday, July 21, and once again the Street is focused on the big numbers -- revenues, earnings and units sold for the Mac, iPhone and iPod.
But savvy analysts will be paying closer attention to the number that is the best measure of a firm's profitibilty: gross margin, expressed as the ratio of profits to revenues. Or
(Revenue - Cost of sales) / Revenue
Apple's gross margins, which have averaged 34.8% over the past eight quarters, are the envy of the industry. Dell's (DELL) first quarter GM, by contrast, was 17.6% and the company warned Wall Street last week that it is expecting a "modest decline" next quarter.
In its April earnings call, Apple low-balled its guidance numbers as usual, forecasting a sharp drop in gross margins over the next 6 months. Specifically, it warned analysts to expect no better than 33% in Q3 and "about 30%" in Q4.
But Turley Muller, for one, doesn't buy those numbers, and he should know.
