Inuvo Is Latest Stock Halted by Circuit Breakers

Aug. 8 (Bloomberg) -- The following securities have been halted by U.S. circuit breakers since they were implemented in June 2010, according to data compiled by Bloomberg.

The curbs were created after the 20-minute rout on May 6, 2010, erased $862 billion from the value of U.S. shares before prices rebounded. The pause lasts five minutes for Standard & Poor’s 500 Index and Russell 1000 Index companies as well as more than 300 exchange-traded funds when they rise or fall at least 10 percent within five minutes.

New rules proposed by exchanges on April 5, 2011, would shift the market to a limit-up/limit-down system that prevents shares from moving more than a certain amount.
