There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Asia Optical was able to grow EPS by 149% in the last twelve months. We note that the earnings per share growth isn't far from the share price growth (of 171%). So this implies that investor expectations of the company have remained pretty steady. We don't think its coincidental that the share price is growing at a similar rate to the earnings per share.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Asia Optical, it has a TSR of 178% for the last 1 year. 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

We're pleased to report that Asia Optical shareholders have received a total shareholder return of 178% over one year. And that does include the dividend. That gain is better than the annual TSR over five years, which is 19%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
