## Executive Summary
Wall Street is experiencing a volatile shift as a global tech sell-off and AI doubts clash with gains in healthcare and progress in US-Iran talks.

## Intelligence Brief
Major indices including the Dow, S&P 500, and Nasdaq have seen plunges and drops driven by a rout in big tech and semiconductor stocks. This downward trend has extended to Asian markets, impacting the KOSPI and Nikkei, as investors weigh doubts surrounding the AI trade. Simultaneously, oil prices have slid to pre-war lows following progress in US-Iran deal talks.


Coverage from Yahoo Finance, The Guardian, and Bloomberg emphasizes the struggle for tech stocks to find their footing, specifically noting Micron's focus during the rout. Conversely, Barron's and WSJ highlight a surge in healthcare, with Moderna emerging as a top S&P 500 stock after a 15% jump tied to new research on autoimmune disorders and drug pipeline updates. Market observers are monitoring the tension between the tech sell-off and geopolitical developments.


Attention remains on whether the US-Iran deal continues to influence oil and bonds, and how AI chip stocks respond after their recent stumble.
