Sino-Platinum Metals Co.,Ltd (SHSE:600459) shareholders should be happy to see the share price up 18% in the last month. But that doesn't change the fact that the returns over the last three years have been less than pleasing. In fact, the share price is down 39% in the last three years, falling well short of the market return.

Since Sino-Platinum MetalsLtd has shed CN¥456m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Sino-Platinum MetalsLtd saw its EPS decline at a compound rate of 0.1% per year, over the last three years. This reduction in EPS is slower than the 15% annual reduction in the share price. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Sino-Platinum MetalsLtd, it has a TSR of -32% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We regret to report that Sino-Platinum MetalsLtd shareholders are down 2.8% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 0.6%. 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. On the bright side, long term shareholders have made money, with a gain of 6% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
