Aon (NYSE:AON) shareholders have earned a 18% CAGR over the last five years

When you buy a stock there is always a possibility that it could drop 100%. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of Aon plc (NYSE:AON) stock is up an impressive 122% over the last five years. And in the last month, the share price has gained 11%. But this could be related to good market conditions -- stocks in its market are up 9.1% in the last month.

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

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. 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 five years of share price growth, Aon achieved compound earnings per share (EPS) growth of 36% per year. This EPS growth is higher than the 17% average annual increase in the share price. So it seems the market isn't so enthusiastic about the stock these days.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Aon the TSR over the last 5 years was 132%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

It's nice to see that Aon shareholders have received a total shareholder return of 5.5% over the last year. Of course, that includes the dividend. Having said that, the five-year TSR of 18% a year, is even better. Potential buyers might understandably feel they've missed the opportunity, but it's always possible business is still firing on all cylinders. 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 Aon (at least 1 which is a bit concerning) , and understanding them should be part of your investment process.
