[CME System Outage May Cause Volatility at U.S. Market Open] Scope Markets analyst Saul Knapps stated that due to the CME system outage, the U.S. stock market might face turbulence when it reopens after the Thanksgiving holiday. Futures trading for indices such as the S&P 500 and Nasdaq 100 were frozen, leading to a backlog of unfulfilled orders, which could result in a surge of concentrated orders when trading resumes. He noted that the suspension of futures trading temporarily deprived the market of a critical price reference tool. Prior to the system outage, U.S. stock index futures were performing positively, with Nasdaq futures frozen at a 0.2% increase, while Dow Jones Industrial Average and S&P 500 futures both rose by 0.1%.
