04:51 PM EST, 11/09/2026 (MT Newswires) -- (Updates with market moves at the end of the day, and other changes, if any.) US benchmark equity indexes rose Monday, rebounding from last week's sell-off that followed concerns about tougher data center regulation. The Nasdaq Composite rose 2.7% to 25,253.14, while the S&P 500 gained 2.4% to 7,549.94. The Dow Jones Industrial Average increased 2.2% to 52,389.75. All sectors ended in the green, led by industrials. The technology sector rallied 2.9%. Wall Street finished last week in the red amid concerns that the Democratic Party's midterm victory could result in data center restrictions.
