The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But if you buy shares in a really great company, you can more than double your money. For example, the BYD Electronic (International) Company Limited (HKG:285) share price has soared 120% in the last three years. Most would be happy with that. On top of that, the share price is up 51% in about a quarter.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

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 three years of share price growth, BYD Electronic (International) achieved compound earnings per share growth of 1.8% per year. In comparison, the 30% per year gain in the share price outpaces the EPS growth. So it's fair to assume the market has a higher opinion of the business than it did three years ago. It's not unusual to see the market 're-rate' a stock, after a few years of growth.

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 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. As it happens, BYD Electronic (International)'s TSR for the last 3 years was 123%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

We regret to report that BYD Electronic (International) shareholders are down 49% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 18%. 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. On the bright side, long term shareholders have made money, with a gain of 8% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
