What is Earnings Yield?

The earnings yield is the reciprocal of the price-earnings ratio (P/E ratio) and is an indicator of the value of a share. The earnings yield is calculated by dividing earnings (last 12 months) by the current market price per share. As a result, earnings yield can be defined as the percentage of a company's earnings per share. It is possible to determine whether certain stocks are overvalued or undervalued by using earnings yield. A wealth manager may determine the optimal allocation of assets based on earnings yield. Stocks with high earnings yields may be undervalued, while stocks with low earnings yields may be overvalued. It is critical to consider the growth potential of the company, as stocks with a high growth potential often have a higher valuation, and therefore may have a lower earnings yield, although the stock price continues to rise. As part of Magic Formula Investing, which was developed by value investor Joel Greenblatt, earnings yield (EY) is an important metric.

The Calculation of the Earnings Yield

Investors may use the earnings yield to determine whether a stock is a good investment or not. Earnings yield is calculated using the following formula:



Illustration of the formula for calculating the earnings yield in percent.


Consider a share with a current price of CHF 100. The share generated earnings per share of CHF 4 (EPS) in the past financial year. The earnings yield is therefore calculated as follows:

Note: The share has a P/E ratio of 25 (= CHF 100 / CHF 4). In other words, the share is valued at twenty-five times the annual profit.

The Earnings Yield Compared to the Price-Earnings Ratio

Whether earnings yield is superior to the price-to-earnings ratio depends on the individual. When it comes to long-term investing, earnings yield is a popular choice. A price-to-earnings ratio, on the other hand, is a more accurate indicator of the potential for short-term price increases. However, both statements are nearly identical. In the end, both ratios are influenced by the share price and earnings per share, and it merely matters which of the two is in the numerator and which is in the denominator.


It is useful for investors who wish to achieve stable dividend income to assess the earnings yield, as it provides a quick glimpse into the potential yield that a share may be able to produce. As the share price rises (assuming earnings remain unchanged), the earnings yield decreases.


Earnings yields appear to be lower the more valuable/expensive an asset is and vice versa. This conclusion, however, is misleading, since value and price are not the same things. Based on both the earnings yield and the P/E ratio, the only conclusion that can be drawn is the current price (share price) in relation to the current earnings. As a result of these ratios, only limited conclusions can be drawn regarding the value of an investment. Investing in securities with high valuations or high price-to-earnings ratios can provide higher earnings over time, thus lowering the P/E ratio and increasing the earnings yield. This is exactly what growth investors are looking for. This can be seen in the case of Amazon, which initially had low earnings and therefore a high P/E ratio as almost all of its earnings were reinvested in its growth.


In contrast, investments with weak valuations and low P/E ratios, for example due to fundamental issues, can generate lower earnings over time. This, in turn, results in a higher P/E ratio and a lower earnings yield. As an example, Nokia was unable to compete with Apple & Co. in the smartphone market.


It is also possible for a high earnings yield and a low P/E ratio to indicate an undervaluation of a company, while a low earnings yield and a high P/E ratio may indicate an overvaluation. When making investment decisions, earnings yield and P/E ratio should not be viewed in isolation. It is therefore advisable to consult a specialist before investing in a company in order to carry out a comprehensive analysis.

Disadvantages of the Earnings Yield

As with P/E ratios, earnings yields vary greatly by industry, country, and year. When comparing earnings yields between companies, only companies in the same industry should be considered. A further disadvantage of earnings yield is that it is calculated retrospectively. Profits from the past are not necessarily indicative of profits in the future. Furthermore, the price of shares can fluctuate greatly in some cases. As a result, the earnings yield changes according to the selected daily price. It is possible to avoid this by using the average value of the share price. Furthermore, it is possible to distort the net profit (for example, due to one-time events). An experienced wealth manager is aware of the difficulties involved in calculating the earnings yield, as well as the P/E ratio, and can thus assist with these calculations in the best way possible.
