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. For example, long term Gaona Aero Material Co., Ltd. (SZSE:300034) shareholders have enjoyed a 59% share price rise over the last half decade, well in excess of the market return of around 15% (not including dividends).

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Over half a decade, Gaona Aero Material managed to grow its earnings per share at 12% a year. The EPS growth is more impressive than the yearly share price gain of 10% over the same period. So one could conclude that the broader market has become more cautious towards the stock.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Gaona Aero Material the TSR over the last 5 years was 63%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Gaona Aero Material shareholders are down 23% for the year (even including dividends), but the market itself is up 14%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 10%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
