RECORD HIGH: Nasdaq Hits All-Time Peak as AI Frenzy Overrides Iran War...

The Nasdaq hit an all-time high on September 23, 2026, driven by renewed investor confidence in artificial intelligence profits after months of skepticism about valuations and practical applications. Memory chip makers and e-commerce platforms led the rally, with Monolithic Power Systems surging 8.1 percent and Shopify jumping 7.1 percent, while Meta's new AI assistant Muse sparked broader optimism about consumer-facing AI products. The rally came as US and Iranian officials held talks on the sidelines of the UN General Assembly, easing immediate geopolitical tensions that had pressured markets and oil prices for weeks.
