It's not possible to invest over long periods without making some bad investments. But you have a problem if you face massive losses more than once in a while. So spare a thought for the long term shareholders of Yihai International Holding Ltd. (HKG:1579); the share price is down a whopping 74% in the last three years. That might cause some serious doubts about the merits of the initial decision to buy the stock, to put it mildly. The more recent news is of little comfort, with the share price down 26% in a year. More recently, the share price has dropped a further 21% in a month.

With the stock having lost 3.3% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

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 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).

Yihai International Holding saw its EPS decline at a compound rate of 0.9% per year, over the last three years. The share price decline of 36% is actually steeper than the EPS slippage. So it seems the market was too confident about the business, in the past.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Yihai International Holding, it has a TSR of -72% for the last 3 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 2.3% in the last year, Yihai International Holding shareholders lost 22% (even including dividends). 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 10% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Consider for instance, the ever-present spectre of investment risk.
