Investing in Swedish Orphan Biovitrum (STO:SOBI) five years ago would have delivered you a 55% gain

If you buy and hold a stock for many years, you'd hope to be making a profit. Better yet, you'd like to see the share price move up more than the market average. Unfortunately for shareholders, while the Swedish Orphan Biovitrum AB (publ) (STO:SOBI) share price is up 48% in the last five years, that's less than the market return. Looking at the last year alone, the stock is up 11%.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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 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, Swedish Orphan Biovitrum actually saw its EPS drop 1.1% per year.

By glancing at these numbers, we'd posit that the decline in earnings per share is not representative of how the business has changed over the years. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

In contrast revenue growth of 13% per year is probably viewed as evidence that Swedish Orphan Biovitrum is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive growth.

What About The Total Shareholder Return (TSR)?

We've already covered Swedish Orphan Biovitrum's share price action, but we should also mention its total shareholder return (TSR). Arguably the TSR is a more complete return calculation because it accounts for the value of dividends (as if they were reinvested), along with the hypothetical value of any discounted capital that have been offered to shareholders. Swedish Orphan Biovitrum hasn't been paying dividends, but its TSR of 55% exceeds its share price return of 48%, implying it has either spun-off a business, or raised capital at a discount; thereby providing additional value to shareholders.

A Different Perspective

We're pleased to report that Swedish Orphan Biovitrum shareholders have received a total shareholder return of 11% over one year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 9% 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.
