QQQ gaps higher and gains 2.99% as AMD tops $1 trillion, while late Hormuz diplomacy unfolds

QQQ and SPY opened above their prior closes and extended their gains during regular trading. At the last available prices, carried through the overnight segment, QQQ was up 2.99% and SPY 1.59%, leaving QQQ ahead by 1.39 percentage points. AMD's move above a $1 trillion market value, Meta and Nvidia AI developments, and SpaceX's increased Nasdaq-100 weight framed the technology-led advance. Brent crude falling below $100 was followed later by U.K. support for Saudi defenses, Franco-U.S. coordination on Hormuz navigation, and informal assurances that Yanbu crude loading could resume.

What shaped the session

1

AI and semiconductor leadership

AMD shares rose more than 9% as its market value passed $1 trillion. Meta's Muse reached the top of the U.S. iPhone free-app chart, Nvidia committed $3 billion to SB Energy, and Meta later announced Muse-powered shopping with Shopify.

2

Nasdaq index flows

SpaceX's Nasdaq-100 weight increased to 2.82%, creating the prospect of billions of dollars in passive buying by index-tracking funds.

3

Rates and inflation

Fed President Alberto Musalem said strong demand and commodity-price shocks beyond oil could require further rate increases, adding a restrictive-policy counterweight to the equity rally.

4

Oil and Middle East crosscurrents

Brent crude fell below $100 for the first time since September 9. Later developments included confirmed U.K. defensive support for Saudi Arabia, French and U.S. coordination on Hormuz navigation, and informal Saudi assurances that Yanbu crude loading could resume soon.
