The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, you can make far more than 100% on a really good stock. One great example is 3i Group plc (LON:III) which saw its share price drive 204% higher over five years. It's also good to see the share price up 19% over the last quarter.

The past week has proven to be lucrative for 3i Group investors, so let's see if fundamentals drove the company's five-year performance.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over half a decade, 3i Group managed to grow its earnings per share at 24% a year. That makes the EPS growth particularly close to the yearly share price growth of 25%. That suggests that the market sentiment around the company hasn't changed much over that time. Indeed, it would appear the share price is reacting to the EPS.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for 3i Group the TSR over the last 5 years was 261%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.



A Different Perspective

It's good to see that 3i Group has rewarded shareholders with a total shareholder return of 89% in the last twelve months. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 29% 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. 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.
