Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. Buying under-rated businesses is one path to excess returns. To wit, the Jiangsu Huahong Technology share price has climbed 99% in five years, easily topping the market return of 32% (ignoring dividends).

Since the stock has added CN¥378m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

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 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.

Over half a decade, Jiangsu Huahong Technology managed to grow its earnings per share at 2.4% a year. This EPS growth is lower than the 15% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

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 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Jiangsu Huahong Technology, it has a TSR of 109% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

While the broader market lost about 7.7% in the twelve months, Jiangsu Huahong Technology shareholders did even worse, losing 25% (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 16%, 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. It's always interesting to track share price performance over the longer term. But to understand Jiangsu Huahong Technology better, we need to consider many other factors.
