The earnings yield is an indication of how much return shareholders' investment in the company earned over the past 12 months. The higher the earnings yield is, the better.
As of today (2026-06-27), the stock price of Castle Biosciences is $24.21.
Castle Biosciences's Earnings per Share (Diluted) for the trailing twelve months (TTM) ended in Mar. 2026 was $-0.44. Therefore, Castle Biosciences's earnings yield of today is N/A%.
The earnings yield does not consider the growth of the business. A better indicator of the attractiveness of an investment which takes growth into account is the Forward Rate of Return (Yacktman) %. Castle Biosciences's Forward Rate of Return (Yacktman) % for the quarter that ended in Mar. 2026 was 0.00%. The Forward Rate of Return uses the normalized Free Cash Flow of the past five years, and considers growth. The forward rate of return can be thought of as the return that investors buying the stock today can expect from it in the future.
If the P/E ratio is an indication of how many years it takes for the company to earn back the stock price shareholders pay to buy the shares, the earnings yield is an indication of how much return shareholders' investment in the company earned over the past 12 months. The higher the earnings yield is, the better.
If a company loses money, the earnings yield is negative. This gives a more straightforward indication that the company is losing money. This is an advantage of using earnings yield instead of the P/E ratio in valuation. For valuation purposes, the P/B Ratio and the P/S Ratio should be used for companies that are losing money.
Like the P/E ratio, the earnings yield can be used to compare investments in different industries. It can even be used to compare the attractiveness of different asset classes such as bonds and cash. Of course, the earnings yield should not be the only factor in deciding which asset classes to invest.
Also similar to the P/E ratio, the earnings yield does not consider the growth of the business. A growing company with the same earnings yield should be more attractive than a company that has the same earnings yield but does not grow.
Just like the P/E Ratio, non-recurring items such as selling part of the business, selling a previous investment, etc., can affect earnings yield dramatically. The earning yield is also a poor indication for cyclical companies. When a cyclical stock has a high earnings yield it is usually at the peak of its cycle.
Castle Biosciences's Earnings per Share (Diluted) for the trailing twelve months (TTM) ended in Mar. 2026 adds up the quarterly data reported by the company within the most recent 12 months, which was $-0.440 Mil.
