Overview
- Nvidia, which reports Wednesday, now carries 9% of the S&P 500’s weight and has driven 20% of the index’s return this year, with options pricing an outsized post‑earnings move.
- Treasury yields have climbed to roughly 4.45%–4.5% after hotter inflation data, a jump that tends to compress valuations of fast‑growing tech stocks tied to AI.
- Samsung and its union extended talks Sunday as a threatened 18‑day strike from May 21 could disrupt high‑bandwidth memory and DRAM supplies that feed AI data centers.
- Market leadership is unusually narrow, with nine of the top ten U.S. stock gainers tied to AI, as Jefferies argues the run is earnings‑driven while other strategists warn of bubble‑like euphoria.
- Investors will also parse Google I/O on May 19–20 for AI product direction, and they expect Nvidia to update on demand for Blackwell and Rubin platforms, margins, and any supply constraints.
