It hasn't been the best quarter for Kainos Group plc (LON:KNOS) shareholders, since the share price has fallen 16% in that time. But that doesn't change the fact that shareholders have received really good returns over the last five years. In fact, the share price is 185% higher today. We think it's more important to dwell on the long term returns than the short term returns. The more important question is whether the stock is too cheap or too expensive today.

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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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, Kainos Group managed to grow its earnings per share at 27% a year. So the EPS growth rate is rather close to the annualized share price gain of 23% per year. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. In fact, the share price seems to largely reflect the EPS growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. As it happens, Kainos Group's TSR for the last 5 years was 209%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!



A Different Perspective

Kainos Group shareholders are down 9.3% for the year (even including dividends), but the market itself is up 5.6%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 25% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. Investors who like to make money usually check up on insider purchases, such as the price paid, and total amount bought.
