AMR Corporation (NYSE: AMR) has now been halted so many times that there may be a discrepancy from source to source on just how many times the stock has halted. By our count, it was eight times. This is due to the single-stock circuit breakers.
The idea of the single-stock circuit breakers came from the Flash Crash. Many investors believe that the frequency that the price moves 10% is happening too often. This is another one of those examples.
