For many investors, the main point of stock picking is to generate higher returns than the overall market. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. Unfortunately, that's been the case for longer term WashTec AG (ETR:WSU) shareholders, since the share price is down 39% in the last three years, falling well short of the market decline of around 12%. But it's up 6.4% in the last week.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Although the share price is down over three years, WashTec actually managed to grow EPS by 7.8% per year in that time. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Or else the company was over-hyped in the past, and so its growth has disappointed.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

Given the healthiness of the dividend payments, we doubt that they've concerned the market. It's good to see that WashTec has increased its revenue over the last three years. If the company can keep growing revenue, there may be an opportunity for investors. You might have to dig deeper to understand the recent share price weakness.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of WashTec, it has a TSR of -28% for the last 3 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!
