S&P 500, NASDAQ and Dow Jones remain positive: Wall Street ends the week on high as AI stocks bounce back; Luminar Technologies rises over 170%, check top gainers and losers

The US stock market rose on Friday (December 19, 2025), boosted by Oracle. The rise in Wall Street came as the artificial intelligence stocks bounced back after days of volatility. All three major Wall Street indexes witnessed gains.

According to CNBC, the Nasdaq Composite increased 1.31%, closing at 23,307.62. The S&P 500 rose 0.88% to end at 6,834.50, while the Dow Jones Industrial Average climbed 183.04 points, or 0.38%, and settled at 48,134.89. It was the second winning day in a row for all three indexes.

Oracle shares rose 6.6% after TikTok agreed to sell its US operations to a new joint venture. The venture includes the software giant and private equity investor Silver Lake.


The latest rise meant a turnaround for the stock, which came under pressure this week after a report revealed that the cloud infrastructure company lost a crucial backer of one of its data center projects over worries about the company’s debt and AI spending levels.
