Positive earnings growth hasn't been enough to get Kainos Group (LON:KNOS) shareholders a favorable return over the last three years

Many investors define successful investing as beating the market average over the long term. But if you try your hand at stock picking, you risk returning less than the market. We regret to report that long term Kainos Group plc (LON:KNOS) shareholders have had that experience, with the share price dropping 49% in three years, versus a market return of about 18%. And more recent buyers are having a tough time too, with a drop of 28% in the last year.

The recent uptick of 6.4% could be a positive sign of things to come, so let's take a look at historical fundamentals.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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 the unfortunate three years of share price decline, Kainos Group actually saw its earnings per share (EPS) improve by 8.3% per year. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Alternatively, growth expectations may have been unreasonable in the past.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

Revenue is actually up 11% over the three years, so the share price drop doesn't seem to hinge on revenue, either. This analysis is just perfunctory, but it might be worth researching Kainos Group more closely, as sometimes stocks fall unfairly. This could present an opportunity.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Kainos Group, it has a TSR of -45% for the last 3 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

While the broader market gained around 15% in the last year, Kainos Group shareholders lost 26% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 0.6% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
