Statistically speaking, long term investing is a profitable endeavour. But along the way some stocks are going to perform badly. For example, after five long years the Enerflex Ltd. (TSE:EFX) share price is a whole 64% lower. That's an unpleasant experience for long term holders. Shareholders have had an even rougher run lately, with the share price down 25% in the last 90 days. We note that the company has reported results fairly recently; and the market is hardly delighted. You can check out the latest numbers in our company report.

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

Enerflex isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last half decade, Enerflex saw its revenue increase by 3.4% per year. That's far from impressive given all the money it is losing. This lacklustre growth has no doubt fueled the loss of 10% per year, in that time. We want to see an acceleration of revenue growth (or profits) before showing much interest in this one. However, it's possible too many in the market will ignore it, and there may be an opportunity if it starts to recover down the track.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. If you are thinking of buying or selling Enerflex stock, you should check out this freereport showing analyst profit forecasts.



What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Enerflex the TSR over the last 5 years was -61%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Investors in Enerflex had a tough year, with a total loss of 20% (including dividends), against a market gain of about 1.8%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 10% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. It's always interesting to track share price performance over the longer term. But to understand Enerflex better, we need to consider many other factors.
