The S&P 500, Nasdaq 100, and Russell 2000 all post fresh closing highs

The S&P 500, Nasdaq-100, and Russell 2000 all climbed to fresh record closing highs, a feat last performed on September 18. This is the fourth consecutive record close for the S&P 500 and the second consecutive record close for the Russell 2000. The Nasdaq-100 crossed the 25,000 resistance level for the first time.

Gains were led by Advanced Micro Devices on news that the chip designer struck a megadeal with OpenAI that “is expected to deliver tens of billions of dollars in revenue,” which sent Nvidia down but lifted up companies in the AI ecosystem like Oklo, Cipher Mining, Super Micro Computer and IREN.
