The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Metals X Limited (ASX:MLX) share price has soared 126% in the last half decade. Most would be very happy with that. But it's down 5.5% in the last week.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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.

During the last half decade, Metals X 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.

The company's earnings per share (over time) is depicted in the image below (click to see the exact numbers).

A Different Perspective

It's good to see that Metals X has rewarded shareholders with a total shareholder return of 59% in the last twelve months. Since the one-year TSR is better than the five-year TSR (the latter coming in at 18% 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. 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.
