Generally speaking long term investing is the way to go. But unfortunately, some companies simply don't succeed. For example, after five long years the Costa Group Holdings Limited (ASX:CGC) share price is a whole 67% lower. That's not a lot of fun for true believers. The falls have accelerated recently, with the share price down 10% in the last three months.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

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. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Costa Group Holdings became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics may better explain the share price move.

Revenue is actually up 6.9% over the time period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized 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?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. In the case of Costa Group Holdings, it has a TSR of -60% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Investors in Costa Group Holdings had a tough year, with a total loss of 8.4% (including dividends), against a market gain of about 1.6%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, longer term shareholders are suffering worse, given the loss of 10% doled out over the last five years. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with Costa Group Holdings , and understanding them should be part of your investment process.
