By Joseph AdinolfiMarketWatch Pulse

The nearly four-hour halt in trading on the New York Stock Exchange Wednesday may have been related to a software update from the night before, according to The Wall Street Journal, which cited a person familiar with the events. It took nearly an hour and a half for the exchange to pinpoint the issue, according to WSJ. But the exact cause is still under investigation. Trading was halted on Wednesday at 11:32 a.m. Eastern, and didn't resume until around 3:10 p.m. Eastern.
