The return on equity ratio or ROE is a profitability ratio that measures the ability of a firm to generate profits from its shareholders investments in the company. In other words, the return on equity ratio shows how much profit each dollar of common stockholdersâ equity generates.
Best Answer: Anyone of those ratios can work but there is no single ratio that will show the return you will get out of a stock. The best thing is use those ratios compared to a company's competitors and see how strong the company is. I do like Return on Equity, ROE, but my favorite that if you don't know about you should research is Return on Invested Capital, ROIC. The reason I like it is that companies can borrow large amounts of money and make their ROE go through the roof making it appeal to more peope.
