The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, you can make far more than 100% on a really good stock. One great example is 5N Plus Inc. (TSE:VNP) which saw its share price drive 197% higher over five years. On top of that, the share price is up 18% in about a quarter. But this could be related to the strong market, which is up 7.7% in the last three months.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the five years of share price growth, 5N Plus moved from a loss to profitability. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider. It might be well worthwhile taking a look at our free report on 5N Plus' earnings, revenue and cash flow.

A Different Perspective

It's good to see that 5N Plus has rewarded shareholders with a total shareholder return of 106% in the last twelve months. That gain is better than the annual TSR over five years, which is 24%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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. Like risks, for instance. Every company has them, and we've spotted 3 warning signs for 5N Plus (of which 1 is concerning!) you should know about.
