What to watch into the next session

Leadership in Semiconductors & Related Devices versus Services Computer Programming, Data Processing, Etc. 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.

KO is a practical barometer for momentum quality, while CAT offers a stress test on the weak side. Keep position sizing adaptive because today's average move sits near -0.44%, 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
