Even the best stock pickers will make plenty of bad investments. Unfortunately, shareholders of Iridium Communications Inc. (NASDAQ:IRDM) have suffered share price declines over the last year. The share price has slid 57% in that time. To make matters worse, the returns over three years have also been really disappointing (the share price is 38% lower than three years ago). Furthermore, it's down 33% in about a quarter. That's not much fun for holders.

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.

Given that Iridium Communications only made minimal earnings in the last twelve months, we'll focus on revenue to gauge its business development. Generally speaking, we'd consider a stock like this alongside loss-making companies, simply because the quantum of the profit is so low. For shareholders to have confidence a company will grow profits significantly, it must grow revenue.

In the last twelve months, Iridium Communications increased its revenue by 9.7%. That's not a very high growth rate considering it doesn't make profits. Without profits, and with revenue growth sluggish, you get a 57% loss for shareholders, over the year. We'd want to see evidence that future revenue growth will be stronger before getting too interested. Of course, the market can be too impatient at times. Why not take a closer look at this one so you're ready to pounce if growth does accelerate.

A Different Perspective

Iridium Communications shareholders are down 56% for the year (even including dividends), but the market itself is up 26%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 0.3% per year over five years. 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. 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.
