Dow Falls 262 After Hours-Long Glitch Still no clear explanation for today's halt in trading By Newser Editors and Wire Services Posted Jul 8, 2015 2:12 PM CDT Updated Jul 8, 2015 3:11 PM CDT 15 comments Comments Traders work on the floor at the New York Stock Exchange Wednesday. (AP Photo/Seth Wenig) (Newser) – The Dow closed a strange day down 262 points, reports TheStreet. The close came after the New York Stock Exchange resumed trading at 3:10 in the wake of an unprecedented delay of nearly four hours. The NYSE hasn't fully explained what happened, describing it as an internal technical issue and not some kind of cyberattack. The Dow was down about 170 when trading was halted, and it lost yet more ground upon the NYSE's reopening. Nasdaq finished down 1.75% and the S&P 500 was off 1.65%. During the hiatus, investors were able to buy and sell stocks listed on the NYSE exchange on other venues, notes the Wall Street Journal.
