The five-year underlying earnings growth at 3SBio (HKG:1530) is promising, but the shareholders are still in the red over that time

In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But even the best stock picker will only win with some selections. At this point some shareholders may be questioning their investment in 3SBio Inc. (HKG:1530), since the last five years saw the share price fall 51%. We also note that the stock has performed poorly over the last year, with the share price down 26%. More recently, the share price has dropped a further 12% in a month. But this could be related to poor market conditions -- stocks are down 5.3% in the same time.

Since 3SBio has shed HK$589m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

See our latest analysis for 3SBio

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.

During the unfortunate half decade during which the share price slipped, 3SBio actually saw its earnings per share (EPS) improve by 11% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

Because of the sharp contrast between the EPS growth rate and the share price growth, we're inclined to look to other metrics to understand the changing market sentiment around the stock.

We note that the dividend has remained healthy, so that wouldn't really explain the share price drop. While it's not completely obvious why the share price is down, a closer look at the company's history might help explain it.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. You can see what analysts are predicting for 3SBio in this interactive graph of future profit estimates.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. As it happens, 3SBio's TSR for the last 5 years was -47%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 15% in the last year, 3SBio shareholders lost 23% (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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 8% over the last half decade. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 1 warning sign with 3SBio , and understanding them should be part of your investment process.
