It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But if you buy shares in a really great company, you can more than double your money. For instance the 3i Group plc (LON:III) share price is 122% higher than it was three years ago. How nice for those who held the stock! On top of that, the share price is up 10% in about a quarter.

So let's assess the underlying fundamentals over the last 3 years and see if they've moved in lock-step with shareholder returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 three years of share price growth, 3i Group achieved compound earnings per share growth of 178% per year. This EPS growth is higher than the 30% average annual increase in the share price. So it seems investors have become more cautious about the company, over time. We'd venture the lowish P/E ratio of 3.94 also reflects the negative sentiment around the stock.

It's good to see that there was some significant insider buying in the last three months. That's 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 3i Group's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for 3i Group the TSR over the last 3 years was 146%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that 3i Group shareholders have received a total shareholder return of 68% over one year. That's including the dividend. That gain is better than the annual TSR over five years, which is 20%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
