Generally speaking long term investing is the way to go. But that doesn't mean long term investors can avoid big losses. Zooming in on an example, the Hongta Securities Co., Ltd. (SHSE:601236) share price dropped 60% in the last half decade. We certainly feel for shareholders who bought near the top.

Since Hongta Securities has shed CN¥1.4b from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

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 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 Hongta Securities' share price and EPS declined; the latter at a rate of 23% per year. The share price decline of 17% per year isn't as bad as the EPS decline. So the market may previously have expected a drop, or else it expects the situation will improve. With a P/E ratio of 147.82, it's fair to say the market sees a brighter future for the business.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Hongta Securities the TSR over the last 5 years was -53%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We regret to report that Hongta Securities shareholders are down 20% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 16%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 9% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
