Aon (NYSE:AON) sheds 4.8% this week, as yearly returns fall more in line with earnings growth

When we invest, we're generally looking for stocks that outperform the market average. Buying under-rated businesses is one path to excess returns. For example, the Aon plc (NYSE:AON) share price is up 96% in the last 5 years, clearly besting the market return of around 78% (ignoring dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 19%, including dividends.

While the stock has fallen 4.8% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During five years of share price growth, Aon achieved compound earnings per share (EPS) growth of 14% per year. That makes the EPS growth particularly close to the yearly share price growth of 14%. This indicates that investor sentiment towards the company has not changed a great deal. Rather, the share price has approximately tracked EPS growth.

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?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Aon the TSR over the last 5 years was 104%, 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

It's good to see that Aon has rewarded shareholders with a total shareholder return of 19% in the last twelve months. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 15% 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.
