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. 1MDB closes the Risk Resilience gap — currently 40 points behind, the largest single contributor to SPY's edge.
  2. 2MDB generates a confirmed bullish trend signal it does not currently carry, such as MACD Bullish Crossover.
  3. 3SPY's conflicting signal state resolves bearish — it currently carries 4 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.
