Samsung settled with its union overnight. Korean semis opened up 5% in pre-market. The Philadelphia Semiconductor Index rallied as US markets closed up over 1% with semis leading the tape.

This is a clean supply-chain read-through. The Samsung strike risk had been a background overhang on memory pricing — specifically HBM (high bandwidth memory) for AI applications. With the agreement in place, HBM supply pressure eases and the bull case for MU and SNDK gets cleaner.

The options market is reflecting it. Implied vol on semis names compressed overnight. NVDA's earnings beat plus Samsung's labour resolution removed two near-term uncertainty events simultaneously. When two vol events resolve in the same session, the compression can be fast and sharp.

Watch the VIX (the volatility index) over the next two sessions. NVDA earnings typically set the tone for sector implied vol. A clean beat plus an USD 80 billion buyback tells dealers to reduce hedges, which supports index levels through vanna flows.

The AI infrastructure vs. legacy semis dispersion trade I've been tracking continues to play out. APLD up 7%, Samsung labour resolved, NVDA printing a record quarter. The thesis is intact.
