Intraday checkpoints to watch today
Maintain prior strength: confirm whether semiconductor post-processing and test names remain stronger than the theme average after the open.
Leader-laggard gap: check if only the leader rises or if the move broadens to second and third tier names.
News and volume confirmation: movements with volume matter more than lone gap-ups.

Risks
If the theme has already spiked recently, watching whether volume holds during pullbacks is more important than chasing the opening price.
Theme strength can change quickly in early trade, so check index direction, FX, and US futures together.
Watch intraday recovery for names that lagged over the past 5 days, such as ISC (095340) -3.06%.
