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.

COST

0 bullish / 3 bearish

  • Death Cross Active bearish, trend, long horizon (1.53%)
  • Downtrend Structure Active bearish, trend, long horizon
  • MACD Bearish Crossover bearish, momentum, short horizon
XLPConflicted

3 bullish / 1 bearish / 2 neutral, conflicted

  • Golden Cross Active bullish, trend, long horizon (2.09%)
  • Bollinger Band Squeeze neutral, volatility, short horizon
  • EMA Ribbon Expansion Bullish bullish, trend, medium horizon

XLP 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.

COSTNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price -1.19%, AIQ 0 points).

XLPNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.68%, AIQ 0 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. 1COST closes the Momentum gap — currently 25 points behind, the largest single contributor to XLP's edge.
  2. 2COST's Death Cross Active resolves — a bearish trend rule currently active against it.
  3. 3XLP'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.

How this comparison is scored

The Algovestiq AIQ Score composites four factors — Quality (30%), Value (30%), Momentum (25%) and Risk (15%). 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.
