When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. For example, the Arthur J. Gallagher & Co. (NYSE:AJG) share price has soared 189% in the last half decade. Most would be very happy with that. And in the last month, the share price has gained 10%. We note that Arthur J. Gallagher reported its financial results recently; luckily, you can catch up on the latest revenue and profit numbers in our company report.

There is no denying that markets are sometimes efficient, but prices do not always reflect 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, Arthur J. Gallagher achieved compound earnings per share (EPS) growth of 10% per year. This EPS growth is lower than the 24% 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. This favorable sentiment is reflected in its (fairly optimistic) P/E ratio of 52.77.

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Arthur J. Gallagher's TSR for the last 5 years was 208%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Arthur J. Gallagher has rewarded shareholders with a total shareholder return of 32% in the last twelve months. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 25% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
