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 instance, the price of Sweco AB (publ) (STO:SWEC B) stock is up an impressive 139% over the last five years. Also pleasing for shareholders was the 20% gain in the last three months. This could be related to the recent financial results, released recently - you can catch up on the most recent data by reading our company report.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

During five years of share price growth, Sweco achieved compound earnings per share (EPS) growth of 20% per year. So the EPS growth rate is rather close to the annualized share price gain of 19% per year. That suggests that the market sentiment around the company hasn't changed much over that time. Indeed, it would appear the share price is reacting to the EPS.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business. It might be well worthwhile taking a look at our free report on Sweco's earnings, revenue and cash flow.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. As it happens, Sweco's TSR for the last 5 years was 183%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that Sweco shareholders have received a total shareholder return of 34% over one year. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 23%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. It is all well and good that insiders have been buying shares, but we suggest you check here to see what price insiders were buying at.
