Microwave Filter Co (OTCPK:MFCO) Net Margin % Explanation
Although Net Income and Earnings-per-Share (EPS) are the most widely used parameter in measuring a company's profitability and valuation, it is the least reliable. The reason is that reported earnings can be manipulated easily by adjusting any numbers such as Depreciation, Depletion and Amotorization and non-recurring items.
But the long term trend of the net margin is a good indicator of the competitiveness and health of the business.
