It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But when you pick a company that is really flourishing, you can make more than 100%. For example, the China National Nuclear Power Co., Ltd. (SHSE:601985) share price has soared 104% in the last three years. That sort of return is as solid as granite. It's also good to see the share price up 16% over the last quarter.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

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

China National Nuclear Power was able to grow its EPS at 11% per year over three years, sending the share price higher. This EPS growth is lower than the 27% 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. It's not unusual to see the market 're-rate' a stock, after a few years of growth.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of China National Nuclear Power, it has a TSR of 119% for the last 3 years. 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

It's nice to see that China National Nuclear Power shareholders have received a total shareholder return of 55% over the last year. That's including the dividend. That gain is better than the annual TSR over five years, which is 17%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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.
