What to watch into the next session
Leadership in Software Services versus AIRCRAFT is the cleanest read for follow-through. If participation stays broad while index moves remain orderly, continuation risk/reward improves. If breadth narrows, the setup becomes more tactical and reversal-prone.
ADBE is a practical barometer for momentum quality, while AMD offers a stress test on the weak side. Keep position sizing adaptive because today's average move sits near 1.26%, which can hide sharp single-name swings.
- Track whether breadth expands beyond index heavyweights
- Confirm momentum with sustained volume rather than open-only spikes
- Reduce conviction if leaders fail to hold their opening range
