Techtronic Industries Company Limited (HKG:669) shareholders might be concerned after seeing the share price drop 12% in the last month. But that doesn't change the fact that shareholders have received really good returns over the last five years. We think most investors would be happy with the 115% return, over that period. So while it's never fun to see a share price fall, it's important to look at a longer time horizon. Ultimately business performance will determine whether the stock price continues the positive long term trend. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 44% drop, in the last year.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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. 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.

During five years of share price growth, Techtronic Industries achieved compound earnings per share (EPS) growth of 21% per year. This EPS growth is higher than the 17% average annual increase in the share price. So it seems the market isn't so enthusiastic about the stock these days.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. We note that for Techtronic Industries the TSR over the last 5 years was 133%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We regret to report that Techtronic Industries shareholders are down 43% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 19%. 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 18%, 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 Techtronic Industries better, we need to consider many other factors.
