NEXT CHECKPOINTS

What to verify next

An event is not a conclusion; it is a set of variables to keep testing.

  1. NEXT

    Check whether today's leadership holds through the next completed session, rather than one-day rotation.

  2. BREADTH

    See whether the lag in Oil & Gas Exploration is a one-session structure or a broader risk split.

  3. VIX

    Volatility is recorded at the close; the next session should confirm whether it moves with the tape.
