Long term investing works well, but it doesn't always work for each individual stock. We really hate to see fellow investors lose their hard-earned money. For example, we sympathize with anyone who was caught holding Cadiz Inc. (NASDAQ:CDZI) during the five years that saw its share price drop a whopping 75%.

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.

Given that Cadiz didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. When a company doesn't make profits, we'd generally hope to see good revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

Over five years, Cadiz grew its revenue at 43% per year. That's better than most loss-making companies. So it's not at all clear to us why the share price sunk 12% throughout that time. It could be that the stock was over-hyped before. While there might be an opportunity here, you'd want to take a close look at the balance sheet strength.

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. So we recommend checking out this free report showing consensus forecasts

A Different Perspective

Investors in Cadiz had a tough year, with a total loss of 14%, against a market gain of about 26%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. However, the loss over the last year isn't as bad as the 12% per annum loss investors have suffered over the last half decade. 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. To that end, you should learn about the 3 warning signs we've spotted with Cadiz (including 1 which is significant) .
