In the last year, many Iridium Communications Inc. (NASDAQ:IRDM) insiders sold a substantial stake in the company which may have sparked shareholders' attention. When analyzing insider transactions, it is usually more valuable to know whether insiders are buying versus knowing if they are selling, as the latter sends an ambiguous message. However, shareholders should take a deeper look if several insiders are selling stock over a specific time period.

Although we don't think shareholders should simply follow insider transactions, we would consider it foolish to ignore insider transactions altogether.
