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. That downside risk was realized by Ampol Limited (ASX:ALD) shareholders over the last year, as the share price declined 47%. That's well below the market decline of 3.8%. Notably, shareholders had a tough run over the longer term, too, with a drop of 32% in the last three years. Furthermore, it's down 27% in about a quarter. That's not much fun for holders. However, one could argue that the price has been influenced by the general market, which is down 12% in the same timeframe.

With the stock having lost 8.5% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

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.

Unhappily, Ampol had to report a 78% decline in EPS over the last year. The share price fall of 47% isn't as bad as the reduction in earnings per share. So despite the weak per-share profits, some investors are probably relieved the situation wasn't more difficult.

A Different Perspective

While the broader market lost about 3.8% in the twelve months, Ampol shareholders did even worse, losing 46% (even including dividends). However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. On the bright side, long term shareholders have made money, with a gain of 2% 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.
