It's easy to match the overall market return by buying an index fund. Active investors aim to buy stocks that vastly outperform the market - but in the process, they risk under-performance. For example, the APA Group (ASX:APA) share price is down 20% in the last year. That falls noticeably short of the market return of around 8.4%. Looking at the longer term, the stock is down 18% over three years.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Even though the APA Group share price is down over the year, its EPS actually improved. It's quite possible that growth expectations may have been unreasonable in the past.

It's fair to say that the share price does not seem to be reflecting the EPS growth. So it's easy to justify a look at some other metrics.

We don't see any weakness in the APA Group's dividend so the steady payout can't really explain the share price drop. The revenue trend doesn't seem to explain why the share price is down. Of course, it could simply be that it simply fell short of the market consensus expectations.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for APA Group the TSR over the last 1 year was -15%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

APA Group shareholders are down 15% for the year (even including dividends), but the market itself is up 8.4%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 1.8% 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. 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.
