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.

  • Golden Cross Active bullish, trend, long horizon (11.92%)
  • Uptrend Structure Active bullish, trend, long horizon
  • MACD Bullish Crossover bullish, momentum, short horizon

2 bullish / 2 bearish, conflicted

  • Golden Cross Active bullish, trend, long horizon (12.70%)
  • Keltner Channel Breakdown bearish, volatility, short horizon
  • EMA Ribbon Expansion Bullish bullish, trend, medium horizon

Price vs model alignment

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

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. 1PAYX closes the Momentum gap — currently 43 points behind, the largest single contributor to KEYS's edge.
  2. 2PAYX's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it.
  3. 3KEYS's Golden Cross Active breaks down — it is the strongest rule currently supporting the verdict.
  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.
