Went public: May 20, 1999
Stock price drop: $84 to $0.09 

With Toys 'R' Us and Amazon dominating the toy market, no one ever saw eToys becoming an overnight success. But through word of mouth it pulled together $166 million for its IPO. The online toy store went public at $20 a share, which surged to $76 by the end of its first day. So how did eToys become such a flop? Failure to keep up with Christmas orders, plus the over-investment of two warehouses and advertising resulted in the company's stock dropping from $84 a share to 9 cents in two years. Bankruptcy followed in 2001.
