What would flip this result

A state, not a forecast. These are the specific, observable changes that would reverse the verdict — not a price prediction.

  1. 1SLG closes the Momentum gap — currently 13 points behind, the largest single contributor to PDM's edge.
  2. 2SLG's Bollinger Band Squeeze turns directional — it is neutral today and would confirm a change in trend.
  3. 3PDM's conflicting signal state resolves bearish — it currently carries 3 bullish and 1 bearish rules at once.
  4. 4A regime shift changes factor weighting — the composite weights Quality and Value at 30% each, so a rotation toward either would move the result most.
