Went public: March 2000

The UK-based travel site grew rapidly on the international front and gained a U.S. following during the dotcom boom. Even when it doubled its share price to $6, the company generated a 28 percent gain on its first day. Two weeks later shares plunged and after Travelocity acquired the company in 2005, investors found themselves selling shares back at $2.75 each. Doesn’t take a math whiz to see why this was a massive IPO failure.
