Generally speaking long term investing is the way to go. But along the way some stocks are going to perform badly. For example, after five long years the Aisino Co.Ltd. (SHSE:600271) share price is a whole 68% lower. That's an unpleasant experience for long term holders. And some of the more recent buyers are probably worried, too, with the stock falling 42% in the last year. More recently, the share price has dropped a further 13% in a month.

After losing 6.3% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

Looking back five years, both AisinoLtd's share price and EPS declined; the latter at a rate of 1.6% per year. This reduction in EPS is less than the 21% annual reduction in the share price. This implies that the market is more cautious about the business these days.

It is of course excellent to see how AisinoLtd has grown profits over the years, but the future is more important for shareholders. If you are thinking of buying or selling AisinoLtd stock, you should check out this FREE detailed 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for AisinoLtd the TSR over the last 5 years was -66%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

We regret to report that AisinoLtd shareholders are down 42% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 17%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 11% over the last half decade. 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with AisinoLtd , and understanding them should be part of your investment process.
