Investors in Centrica (LON:CNA) have seen massive returns of 303% over the past five years

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 Centrica plc (LON:CNA) which saw its share price drive 268% higher over five years. We note the stock price is up 1.3% in the last seven days.

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

Centrica wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. When a company doesn't make profits, we'd generally hope to see good revenue growth. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

In the last 5 years Centrica saw its revenue grow at 13% per year. That's a pretty good long term growth rate. We'd argue this growth has been reflected in the share price which has climbed at a rate of 30% per year over in that time. It's well worth monitoring the growth trend in revenue, because if growth accelerates, that might signal an opportunity. Accelerating growth can be a sign of an inflection point - and could indicate profits lie ahead. Worth watching 100%

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business. So it makes a lot of sense to check out what analysts think Centrica will earn in the future (free profit forecasts).

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Centrica the TSR over the last 5 years was 303%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Centrica shareholders have received a total shareholder return of 38% over one year. Of course, that includes the dividend. That's better than the annualised return of 32% over half a decade, implying that the company is doing better recently. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. It's always interesting to track share price performance over the longer term. But to understand Centrica better, we need to consider many other factors.
