US stocks close higher: Dow +2.21%, Nasdaq +3.33%, S&P 500 +2.32%; AMD jumps 13.61%

The breadth of the rally matters more than the index levels: gains spanned mega-cap tech, semiconductors and industrials names like AMD, Micron and Tesla together, which points to a broad risk-on session rather than a single-sector move. AMD's outsized jump stands apart from the rest of the leaderboard, suggesting company-specific news or positioning drove it rather than the tape alone. The open question is whether this breadth holds or narrows back to a handful of chip names.
