The reporter's first two sentences -- "In the 1990s, there was the dot-com boom. Now, there's the Iraq bubble." -- is dated. The bubble for security firms in Iraq was in 2004. That's when ArmorGroup listed in London and the shares took off. When Iraq didn't pan out to be the easy money the anti-mercenary crowd claimed (and still claim it is) the stock crashed.
I bought ArmorGroup stock because it had a strong balance sheet, and its shares traded just under net tangible asset value. Investors sure didn't see easy money coming from Iraq then (and we shouldn't now).
Like any article on security firms in Iraq, you'll read about Tim Spicer of Aegis (a competitor of ArmorGroup). Spicer's autobiography, An Unorthodox Soldier, is mentioned. The book was written in 1999 and in some ways is dated. After all, it's written before the September 11 terrorist attacks and before Spicer launched Aegis. But in the end of the book he proves to be [IMHO] somewhat prescient about future events.
