Statistically speaking, long term investing is a profitable endeavour. But that doesn't mean long term investors can avoid big losses. For example the KAP Limited (JSE:KAP) share price dropped 65% over five years. We certainly feel for shareholders who bought near the top. And some of the more recent buyers are probably worried, too, with the stock falling 39% in the last year. The falls have accelerated recently, with the share price down 16% in the last three months.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

View our latest analysis for KAP

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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.

During the unfortunate half decade during which the share price slipped, KAP actually saw its earnings per share (EPS) improve by 2.5% per year. So it doesn't seem like EPS is a great guide to understanding how the market is valuing the stock. Alternatively, growth expectations may have been unreasonable in the past.

By glancing at these numbers, we'd posit that the the market had expectations of much higher growth, five years ago. Looking to other metrics might better explain the share price change.

The steady dividend doesn't really explain why the share price is down. It's not immediately clear to us why the stock price is down but further research might provide some answers.

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, KAP's TSR for the last 5 years was -58%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market gained around 7.5% in the last year, KAP shareholders lost 34% (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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 10% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with KAP (at least 1 which can't be ignored) , and understanding them should be part of your investment process.
