Semis alone dropped ~4% — why did the indexes hold?

On the 24th (local time), a semiconductor sell-off (SOXX -4.4%) pulled the Nasdaq -0.6%, while the S&P 500 +0.1% and Dow +0.5% closed higher — a chip-contained pullback, not a broad decline.

• Intel -7.9%, Marvell -7.2%, Micron -7.0% fell together as STMicro's guidance miss in Europe soured chip sentiment

• Volatility index VIX 18.58 (-0.6%) eased — a sector-level move, not a broad exit from risk assets

• 10-year Treasury yield -2.4bp and oil -1.9% also cooled

• After the AI rally's run-up, positioning was trimmed ahead of earnings — Citi calls the pullback a buying opportunity

• More a valuation give-back than a demand-damage signal; direction rests on the individual prints
