The 5.4% return this week takes Bilfinger's (ETR:GBF) shareholders five-year gains to 496%

For many, the main point of investing in the stock market is to achieve spectacular returns. And highest quality companies can see their share prices grow by huge amounts. Don't believe it? Then look at the Bilfinger SE (ETR:GBF) share price. It's 326% higher than it was five years ago. And this is just one example of the epic gains achieved by some long term investors. It's also up 16% in about a month. We note that Bilfinger reported its financial results recently; luckily, you can catch up on the latest revenue and profit numbers in our company report.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

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 the five years of share price growth, Bilfinger moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. Since the company was unprofitable five years ago, but not three years ago, it's worth taking a look at the returns in the last three years, too. Indeed, the Bilfinger share price has gained 282% in three years. Meanwhile, EPS is up 28% per year. Notably, the EPS growth has been slower than the annualised share price gain of 56% over three years. So it's fair to assume the market has a higher opinion of the business than it did three years ago.

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. In the case of Bilfinger, it has a TSR of 496% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Bilfinger shareholders have received a total shareholder return of 140% over one year. Of course, that includes the dividend. That's better than the annualised return of 43% over half a decade, implying that the company is doing better recently. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 1 warning sign with Bilfinger , and understanding them should be part of your investment process.
