Be Aware

Compared with a company's EBITDA margin, Operating Margin can be manipulated by adjusting the rate of depreciation, depletion and amortization (DDA).

If a company is facing competition, its Operating Margin may decline. Often the Operating Margin declines well before the company's revenue or even profit decline. Therefore, Operating Margin is a very important indicator of whether the company is facing problems.

For instance, by 2012, Nokia (NOK)'s problems were well known and its stock had lost more than 90% of its market value since 2007. But Nokia's Operating Margin had already been in decline since 2002, although its earnings per share were still rising. Investors who paid attention to Operating Margin would have avoided this huge loss. The same can be said for Research-in-Motion (RIMM).

Therefore, Operating Margin is a very important screening filter for GuruFocus. GuruFocus's Buffett-Munger screener requires that the profit margin is either consistent or expanding. The Model Portfolio of the Buffett-Munger screener has outperformed the market every year since inception in 2009.
