Stock rose on Friday following a “cooling issue” at a data center that caused a disruption in assets traded at the Chicago Mercantile Exchange.
The Dow Jones Industrial Average gained 84 points, or 0.2%. The S&P 500 and Nasdaq Composite advanced 0.2% and 0.3%, respectively.
The disruption could cause even more volatility, as Wall Street comes back from the Thanksgiving holiday for a shortened trading session on Friday. Trading volumes the day after Thanksgiving are historically well below average, meaning moves — to the upside and the downside — could be more extreme.
Friday also marks the last trading day of November. A pullback in tech stocks have weighed on the major averages this month, as doubt swirled around the future profitability of AI companies.
Yet some investors are hopeful that this month’s slide will mean a year-end rally is in store for the major averages, as they step into buy stocks that have been unduly punished at more attractive valuations.
The Dow and the S&P 500 were slightly lower on the month, each set to snap six straight months of gains. The Nasdaq fell 2%, on track to end a seven month advance.
Stocks are on pace to wrap up a winning week, following a turnaround in tech names. The Dow is up more than 2% week to date, while the S&P 500 and Nasdaq Composite are higher by 3% and 4%, respectively, in the weekly period.
