Generally speaking, investors are inspired to be stock pickers by the potential to find the big winners. Mistakes are inevitable, but a single top stock pick can cover any losses, and so much more. One bright shining star stock has been Perfect Shape Medical Limited (HKG:1830), which is 373% higher than three years ago. Unfortunately, though, the stock has dropped 5.3% over a week. This could be related to the recent financial results, released recently -- you can catch up on the most recent data by reading our company report.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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.

During three years of share price growth, Perfect Shape Medical achieved compound earnings per share growth of 64% per year. We note that the 68% yearly (average) share price gain isn't too far from the EPS growth rate. Coincidence? Probably not. This observation indicates that the market's attitude to the business hasn't changed all that much. Quite to the contrary, the share price has arguably reflected the EPS growth.

You can see how EPS has changed over time in the image below (click on the chart to see the exact values).

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

What about the Total Shareholder Return (TSR)?

We've already covered Perfect Shape Medical's share price action, but we should also mention its 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. Its history of dividend payouts mean that Perfect Shape Medical's TSR of 621% over the last 3 years is better than the share price return.

A Different Perspective

It's nice to see that Perfect Shape Medical shareholders have received a total shareholder return of 48% over the last year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 22% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time.
