When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. Long term YanKer shop Food Co.,Ltd (SZSE:002847) shareholders would be well aware of this, since the stock is up 202% in five years. It's also good to see the share price up 34% over the last quarter. But this move may well have been assisted by the reasonably buoyant market (up 28% in 90 days).

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Over half a decade, YanKer shop FoodLtd managed to grow its earnings per share at 40% a year. This EPS growth is higher than the 25% average annual increase in the share price. Therefore, it seems the market has become relatively pessimistic about the company.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

It is of course excellent to see how YanKer shop FoodLtd has grown profits over the years, but the future is more important for shareholders. Take a more thorough look at YanKer shop FoodLtd's financial health with this free report on its balance sheet.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, YanKer shop FoodLtd's TSR for the last 5 years was 227%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

YanKer shop FoodLtd shareholders are down 0.7% for the year (even including dividends), but the market itself is up 7.8%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 27% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand YanKer shop FoodLtd better, we need to consider many other factors.
