The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For example, the Prestige Consumer Healthcare Inc. (NYSE:PBH) share price has soared 144% in the last half decade. Most would be very happy with that. Also pleasing for shareholders was the 16% gain in the last three months. But this move may well have been assisted by the reasonably buoyant market (up 8.3% in 90 days).

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

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...' 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.

Prestige Consumer Healthcare's earnings per share are down 1.6% per year, despite strong share price performance over five years. This was, in part, due to extraordinary items impacting earning in the last twelve months.

So it's hard to argue that the earnings per share are the best metric to judge the company, as it may not be optimized for profits at this point. Therefore, it's worth taking a look at other metrics to try to understand the share price movements.

On the other hand, Prestige Consumer Healthcare's revenue is growing nicely, at a compound rate of 4.2% over the last five years. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

A Different Perspective

Prestige Consumer Healthcare shareholders are up 15% for the year. But that was short of the market average. 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 20% over five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
