Anhui Anfu Battery Technology Co.,Ltd (SHSE:603031) shareholders might be concerned after seeing the share price drop 21% in the last quarter. But that scarcely detracts from the really solid long term returns generated by the company over five years. In fact, the share price is 103% higher today. To some, the recent pullback wouldn't be surprising after such a fast rise. The more important question is whether the stock is too cheap or too expensive today. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 32% drop, in the last year.

Since the long term performance has been good but there's been a recent pullback of 8.4%, let's check if the fundamentals match the share price.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the five years of share price growth, Anhui Anfu Battery TechnologyLtd moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Anhui Anfu Battery TechnologyLtd's TSR for the last 5 years was 105%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market lost about 17% in the twelve months, Anhui Anfu Battery TechnologyLtd shareholders did even worse, losing 31% (even including dividends). Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Longer term investors wouldn't be so upset, since they would have made 15%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
