When we invest, we're generally looking for stocks that outperform the market average. And while active stock picking involves risks (and requires diversification) it can also provide excess returns. For example, long term Sonic Healthcare Limited (ASX:SHL) shareholders have enjoyed a 34% share price rise over the last half decade, well in excess of the market return of around 12% (not including dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 4.9% , including dividends .

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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, Sonic Healthcare achieved compound earnings per share (EPS) growth of 14% per year. The EPS growth is more impressive than the yearly share price gain of 6% over the same period. So one could conclude that the broader market has become more cautious towards the stock.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Sonic Healthcare the TSR over the last 5 years was 55%, 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

Sonic Healthcare shareholders gained a total return of 4.9% during the year. But that return falls short of the market. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 9% over five years. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. 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.
