US stocks are expected to face opening volatility due to a CME system outage.

On November 28th (UTC+8), the unfulfilled orders caused by the freeze in futures trading, including the S&P 500 index and the Nasdaq 100 index, will lead to a surge of orders when trading resumes.

"Because futures trading was forced to pause, the market temporarily lost a major tool for judging where prices should be," Knapp said.
