U.S. stock futures held steady on Wednesday following record-setting highs for both the S&P 500 and Nasdaq Composite in the prior session. In after-hours trading, Paramount Global's shares soared 7% on news of a preliminary merger agreement with Skydance Media. On Tuesday, the S&P 500 and Nasdaq Composite climbed by 0.62% and 0.84%, respectively, with the Dow also rising 0.41%. These gains were fueled by the ongoing surge in mega-cap tech stocks, notably Apple (up 1.6%), Amazon (up 1.4%), and Alphabet (up 1.2%). Tesla experienced a remarkable jump of 10.2% following better-than-expected delivery numbers, while Nvidia dipped by 1.3% due to concerns over the longevity of the AI-driven market rally. Federal Reserve Chairman Jerome Powell acknowledged progress in taming inflation but stressed that it is not yet time to reduce interest rates. On the economic front, the JOLTS report indicated a slight increase in job openings for May compared to the previous month.
