Eric Criscuolo, Market Strategist at the NYSE, covers a volatile week dominated by the Fed's 25bp rate hike, which came alongside hawkish commentary from Chair Warsh that pushed yields sharply higher and briefly knocked the S&P below its 7,600 trading-range floor. Markets also grappled with a fresh AI storyline as Anthropic's CEO called for slowing model development, triggering a selloff in AI hardware and infrastructure names even as software stocks rallied on the rotation. Escalating Middle East tensions kept oil elevated and added further pressure on equities before easing into week's end. Healthcare and Communication Services were the week's standout sectors, while Financials and Industrials lagged on yield-curve flattening and pricing pressures flagged by trucking peers.
