Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. But if you buy individual stocks, you can do both better or worse than that. Unfortunately the Alliance Pharma plc (LON:APH) share price slid 40% over twelve months. That contrasts poorly with the market decline of 13%. Longer term shareholders haven't suffered as badly, since the stock is down a comparatively less painful 15% in three years. Shareholders have had an even rougher run lately, with the share price down 38% in the last 90 days.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

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...' 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, Alliance Pharma had to report a 33% decline in EPS over the last year. We note that the 40% share price drop is very close to the EPS drop. So it seems that the market sentiment has not changed much, despite the weak results. Rather, the share price has approximately tracked EPS growth.

A Different Perspective

We regret to report that Alliance Pharma shareholders are down 39% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 13%. 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. Longer term investors wouldn't be so upset, since they would have made 3%, each year, over five years. 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.
