The Earnings Yield is a simple but powerful tool for measuring a company's stock performance. It refers to the earnings per share for the most recent 12-month period divided by the current market price per share. This number tells you how much profit a company is making on each dollar you invest in its stock.A high earnings yield means that the company is generating a lot of profits compared to its market value, while a low one means that it's not generating as much profit. This can be helpful for investors who want to find companies with good value - those whose stock prices may not reflect all of their underlying profits.Keep in mind, though, that an earnings yield doesn't tell the whole story. It's important to also look at things like how fast the company is growing and how risky its business model is before making any decisions about investing in it
