AIQ Decision Stability

Fragile

The conclusion is sensitive to small changes. Treat the lead as provisional and watch the flip conditions below.

  • The AIQ gap is moderate at 8 points.
  • Only 2 of 4 covered evidence groups agree. (argues the conclusion is provisional)
  • The lead has already changed hands inside the comparison window. (argues the conclusion is provisional)
  • The lead has been steady session to session. (supports the conclusion holding)
  • The leader is throwing conflicting signals. (argues the conclusion is provisional)
  • Signal direction runs against the verdict: the leader is net-bearish while the laggard is net-bullish. (argues the conclusion is provisional)

Stability combines the score gap, how broadly the evidence agrees, how steady the lead has been across daily snapshots, the current signal state on both names, and analyst dispersion on MBB.

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.

MBBConflicted

1 bullish / 3 bearish / 2 neutral, conflicted

  • Bollinger Band Squeeze — neutral, volatility, short horizon
  • Death Cross Active — bearish, trend, long horizon (2.68%)

Only MINT

  • Golden Cross Active — bullish, trend, long horizon (0.01%)

  • 52-Week High Proximity — bullish, risk, long horizon (0.3%)

Both carry 3 more signals that do not separate them: ATR Contraction - Coiling, 52-Week Low Proximity, MACD Bullish Crossover.

MBB leads the comparison while carrying a conflicted signal state, which is one reason the stability rating is not higher.

Price vs model alignment

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

MBBNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.06%, AIQ +1 points).

MINTNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.04%, 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. 1MINT closes the Risk Resilience gap — currently 21 points behind, the largest single contributor to MBB's edge.
  2. 2MINT's 52-Week Low Proximity resolves — a bearish risk rule currently active against it.
  3. 3MBB's conflicting signal state resolves bearish — it currently carries 1 bullish and 3 bearish rules at once.
  4. 4A regime shift changes factor weighting — Quality and Value carry the heaviest weights in the composite, so a rotation toward either would move the result most.

How this comparison is scored

The Algovestiq AIQ Score composites four factors — Quality, Value, Momentum and Risk, each carrying a fixed weight. Sentiment is reported separately as SentimentPulse and is not folded into the composite. Scores refresh every trading day, and this page regenerates from the latest snapshot rather than being written once.

The verdict names a leader, states how broadly six independent evidence groups agree, and rates how durable that conclusion is given the score gap, its recent trajectory and the current signal state on both names.
