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%. One great example is Melbana Energy Limited (ASX:MAY) which saw its share price drive 230% higher over five years. And in the last month, the share price has gained 50%. This could be related to the recent financial results that were recently released - you could check the most recent data by reading our company report.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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, Melbana Energy 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 probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. This free interactive report on Melbana Energy's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

What About The Total Shareholder Return (TSR)?

We've already covered Melbana Energy's share price action, but we should also mention its total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Melbana Energy hasn't been paying dividends, but its TSR of 234% exceeds its share price return of 230%, implying it has either spun-off a business, or raised capital at a discount; thereby providing additional value to shareholders.

A Different Perspective

While the broader market gained around 21% in the last year, Melbana Energy shareholders lost 52%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 27%, 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. Consider for instance, the ever-present spectre of investment risk. We've identified 3 warning signs with Melbana Energy (at least 2 which are concerning) , and understanding them should be part of your investment process.
