* Undoes trades from 2:40-2:50 pm moving more than 60 pct
* Decision cannot be appealed
NEW YORK, May 6 (Reuters) - Stock exchange operator Nasdaq OMX Group Inc (NDAQ.O) issued the names of hundreds of stocks for which it is canceling trades following Thursday’s sudden stock market plunge.
Soon after 2:30 p.m. ET (1830 GMT), the Dow Jones Industrial Average fell nearly 1,000 points in its largest ever intraday points drop, which may have involved a trading error. [ID:nN06244510]
Nasdaq said it is canceling all trades executed between 2:40 p.m. and 2:50 p.m. when the quote deviated more than 60 percent away from the consolidated last print in that security at about 2:40 p.m.
Nasdaq said its decision was made in conjunction with other exchanges and said it could not be appealed.
