$SMH tagged its 50-day MA yesterday and printed a sketchy candle. Could see a pullback toward the 20-day MA, or deeper if $NVDA earnings on Aug 26 disappoint. Semis are cycle-sensitive — if we're still mid-cycle this is noise, but if we're topping it's rotation time. Watch $NVDA's guidance more than the beat itself. If semis roll, that's your signal to trim exposure or rotate into defensives. Not panicking yet, just marking the level.
