Investors in K3 Capital Group (LON:K3C) have made a impressive return of 178% over the past five years

When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. Long term K3 Capital Group PLC (LON:K3C) shareholders would be well aware of this, since the stock is up 129% in five years. It's also up 13% in about a month.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

Check out our latest analysis for K3 Capital Group

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

During five years of share price growth, K3 Capital Group actually saw its EPS drop 17% per year.

This means it's unlikely the market is judging the company based on earnings growth. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

We note that the dividend is higher than it was previously - always nice to see. Maybe dividend investors have helped support the share price.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, K3 Capital Group's TSR for the last 5 years was 178%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Investors in K3 Capital Group had a tough year, with a total loss of 23% (including dividends), against a market gain of about 1.8%. 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 23% 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.
