The simplest way to invest in stocks is to buy exchange traded funds. But the truth is, you can make significant gains if you buy good quality businesses at the right price. For example, the CBRE Group, Inc. (NYSE:CBRE) share price is up 92% in the last five years, slightly above the market return. We're also happy to report the stock is up a healthy 39% in the last year.

Since the stock has added US$1.1b to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Over half a decade, CBRE Group managed to grow its earnings per share at 0.9% a year. This EPS growth is lower than the 14% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

You can see how EPS has changed over time in the image below (click on the chart to see the exact values).

A Different Perspective

It's nice to see that CBRE Group shareholders have received a total shareholder return of 39% over the last year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 14% 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. Take risks, for example - CBRE Group has 2 warning signs we think you should be aware of.
