When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on a lighter note, a good company can see its share price rise well over 100%. One great example is Argo Group Limited (LON:ARGO) which saw its share price drive 118% higher over five years. In the last week shares have slid back 2.0%.

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 last half decade, Argo Group became profitable. 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.

A Different Perspective

We're pleased to report that Argo Group shareholders have received a total shareholder return of 38% over one year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 17% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper.
