Electronic Trading Continues After NYSE Outage

Technical issues forced the New York Stock Exchange to halt trading on all symbols today, injecting some jitters into a market that was already grappling with Greece- and China-related volatility.

The trading halt, which began around 11:30 a.m. ET and ended at 3:10 p.m., according to CNBC, only affected floor trading, which typically accounts for a quarter of all volume for NYSE-listed securities. The NYSE's electronic Arca exchange was unaffected, allowing for stocks and ETFs to continue trading.

Likewise, other exchanges—such as Nasdaq—reported no problems, and stocks and the broader market continued to fluctuate as normal for the most part.

Based on the current evidence, the NYSE halt seems to have been a technical outage and nothing more. Of course, that didn't keep some market commentators from throwing around more interesting theories.

Pushing back against such rumors, White House Press Secretary Josh Earnest remarked that the NYSE outage was unlikely the result of a cyberattack, and there were no indications it was linked to the computer problems that grounded United Airline flights earlier in the day.

“There is no indication that there are malicious actors involved,” he said.
