What Could Go Wrong With Eaton Stock?

Eaton's net margin is the number a holder should watch now. That margin, the share of each sales dollar kept as profit, was 12.8% over the last twelve months. It has been shrinking. Yet the stock's price relative to earnings is in the top tenth of its ten-year range. At that level, the price likely assumes profits will widen. Is the squeeze on Eaton's margin a passing one.
