Those who invested in Somnigroup International (NYSE:SGI) five years ago are up 304%

The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. One great example is Somnigroup International Inc. (NYSE:SGI) which saw its share price drive 285% higher over five years. It's also good to see the share price up 23% over the last quarter. But this could be related to the strong market, which is up 18% in the last three months.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Over half a decade, Somnigroup International managed to grow its earnings per share at 5.1% a year. This EPS growth is lower than the 31% 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. That's not necessarily surprising considering the five-year track record of earnings growth. This favorable sentiment is reflected in its (fairly optimistic) P/E ratio of 55.34.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Somnigroup International, it has a TSR of 304% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that Somnigroup International shareholders have received a total shareholder return of 51% over one year. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 32% 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. It's always interesting to track share price performance over the longer term. But to understand Somnigroup International better, we need to consider many other factors.
