Worst U.S. Initial Public Offering

Tremor Video

-60.6%

Shares of Tremor Video (TRMR) dropped by half on Nov. 8 after the company's third quarter report spooked investors. A provider of technology for online video advertising, Tremor said fourth-quarter sales would be lower than expected. Executives blamed the decline in the forecast on shifting dynamics in the ad industry. An investor class-action lawsuit filed Nov. 26 alleges that Tremor should have disclosed before its June IPO that it was losing sales due to "its inferior mobile browsing capabilities." A Tremor spokeswoman declined to comment on a pending lawsuit.

Of 163 U.S. IPOs in 2013 with a market capitalization of at least $250 million, measured from opening price.
