Investor (STO:INVE A) shareholders have earned a 21% CAGR over the last five years

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But when you pick a company that is really flourishing, you can make more than 100%. For example, the Investor AB (publ) (STO:INVE A) share price has soared 139% in the last half decade. Most would be very happy with that.

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.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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, Investor achieved compound earnings per share (EPS) growth of 56% per year. This EPS growth is higher than the 19% average annual increase in the share price. Therefore, it seems the market has become relatively pessimistic about the company. The reasonably low P/E ratio of 4.42 also suggests market apprehension.

The company's earnings per share (over time) is depicted in the image below (click to see the exact numbers).

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. This free interactive report on Investor's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

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 is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Investor, it has a TSR of 162% 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 Investor shareholders have received a total shareholder return of 40% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 21% 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. 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 2 warning signs with Investor , and understanding them should be part of your investment process.
