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.

MARConflicted

2 bullish / 1 bearish, conflicted

  • Golden Cross Active bullish, trend, long horizon (4.98%)
  • RSI Oversold - Potential Bounce bullish, momentum, short horizon
  • MACD Bearish Crossover bearish, momentum, short horizon

  • Golden Cross Active bullish, trend, long horizon (6.28%)
  • EMA Ribbon Expansion Bullish bullish, trend, medium horizon
  • 52-Week High Proximity bullish, risk, long horizon (0.8%)

SPY 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.

MARNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.13%, AIQ 0 points).

SPYNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price -0.39%, 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. 1MAR closes the Quality gap — currently 45 points behind, the largest single contributor to SPY's edge.
  2. 2MAR's MACD Bearish Crossover resolves — a bearish momentum rule currently active against it.
  3. 3SPY's conflicting signal state resolves bearish — it currently carries 4 bullish and 1 bearish rules at once.
  4. 4The narrowing continues — the lead has already given back 5 points over 30 sessions, and a further 31-point move would eliminate SPY's advantage entirely.

Which has stronger momentum, MAR or SPY?

SPY on the Momentum factor, by 36 points. Momentum carries 25% of the AIQ composite. It has documented persistence over three- to twelve-month horizons, which makes it a timing input rather than a reason to hold something indefinitely.

What would change the MAR vs SPY verdict?

The result is a state, not a forecast, so it changes when the underlying evidence changes.

What do the current signals say about MAR and SPY?

MAR: 2 bullish / 1 bearish, conflicted. SPY: 4 bullish / 1 bearish / 1 neutral, conflicted. A conflicted state means bullish and bearish rules are active on the same name at once — the technical evidence is not pointing one way, and a decision taken on it carries more timing risk.

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.
