AIQ Signal Divergence

Only the signals that bear on the head-to-head. A conflicted name is carrying bullish and bearish rules at the same time — the technical evidence is not pointing one way.

BILConflicted

2 bullish / 3 bearish / 2 neutral, conflicted

  • Golden Cross Active bullish, trend, long horizon (0.02%)
  • Keltner Channel Breakdown bearish, volatility, short horizon
  • 52-Week High Proximity bullish, risk, long horizon (0.4%)
IEF

0 bullish / 4 bearish / 2 neutral

  • Death Cross Active bearish, trend, long horizon (1.87%)
  • Bollinger Band Squeeze neutral, volatility, short horizon
  • 52-Week Low Proximity bearish, risk, long horizon (0.3%)

BIL is conflicted, so the timing case there is weaker than the score alone suggests.

Price vs model alignment

Whether the latest session's price move confirms what the model did over the same session, or contradicts it.

BILNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.03%, AIQ 0 points).

IEFNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price -0.03%, AIQ +1 points).

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. 1BIL closes the Risk Resilience gap — currently 23 points behind, the largest single contributor to IEF's edge.
  2. 2BIL's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it.
  3. 3IEF starts generating bearish momentum or trend signals.
  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.
