International Consolidated Airlines Group's (LON:IAG) investors will be pleased with their enviable 316% return over the last five years

Long term investing can be life changing when you buy and hold the truly great businesses. And highest quality companies can see their share prices grow by huge amounts. For example, the International Consolidated Airlines Group S.A. (LON:IAG) share price is up a whopping 304% in the last half decade, a handsome return for long term holders. And this is just one example of the epic gains achieved by some long term investors. On top of that, the share price is up 15% in about a quarter.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, International Consolidated Airlines 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.

It is of course excellent to see how International Consolidated Airlines Group has grown profits over the years, but the future is more important for shareholders. It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for International Consolidated Airlines Group the TSR over the last 5 years was 316%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

We're pleased to report that International Consolidated Airlines Group shareholders have received a total shareholder return of 90% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 33% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
