While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

China Unicom (Hong Kong) was able to grow its EPS at 9.7% per year over three years, sending the share price higher. This EPS growth is lower than the 35% average annual increase in the share price. This indicates that the market is feeling more optimistic on the stock, after the last few years of progress.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, China Unicom (Hong Kong)'s TSR for the last 3 years was 195%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

China Unicom (Hong Kong) provided a TSR of 34% over the year (including dividends). That's fairly close to the broader market return. Most would be happy with a gain, and it helps that the year's return is actually better than the average return over five years, which was 19%. Even if the share price growth slows down from here, there's a good chance that this is business worth watching in the long term. 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.
