In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But the main game is to find enough winners to more than offset the losers So we wouldn't blame long term Hengan International Group Company Limited (HKG:1044) shareholders for doubting their decision to hold, with the stock down 59% over a half decade. And it's not just long term holders hurting, because the stock is down 36% in the last year. More recently, the share price has dropped a further 12% in a month.

Since Hengan International Group has shed HK$1.5b from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

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.

Looking back five years, both Hengan International Group's share price and EPS declined; the latter at a rate of 13% per year. This reduction in EPS is less than the 16% annual reduction in the share price. This implies that the market was previously too optimistic about the stock.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Hengan International Group, it has a TSR of -48% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market lost about 19% in the twelve months, Hengan International Group shareholders did even worse, losing 33% (even including dividends). 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 8% 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. 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.
