Stock pickers are generally looking for stocks that will outperform the broader market. Buying under-rated businesses is one path to excess returns. For example, long term China Sunshine Paper Holdings Company Limited (HKG:2002) shareholders have enjoyed a 77% share price rise over the last half decade, well in excess of the market return of around 10% (not including dividends).

Since the stock has added HK$202m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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.

China Sunshine Paper Holdings' earnings per share are down 9.3% per year, despite strong share price performance over five years.

This means it's unlikely the market is judging the company based on earnings growth. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

In contrast revenue growth of 6.4% per year is probably viewed as evidence that China Sunshine Paper Holdings is growing, a real positive. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for China Sunshine Paper Holdings the TSR over the last 5 years was 96%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

China Sunshine Paper Holdings shareholders are down 12% for the year (even including dividends), but the market itself is up 36%. 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 14%, 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.
