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.

- Keltner Channel Breakdown — bearish, volatility, short horizon

What would flip this result

- 2PSA's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it.
- 3SELF's conflicting signal state resolves bearish — it currently carries 2 bullish and 1 bearish rules at once.
- 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.

Which has stronger momentum, PSA or SELF?
SELF on the Momentum factor, by 8 points. Momentum is one of the four weighted factors in 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.
Which is riskier, PSA or SELF?
PSA is the more resilient of the two, so the other name carries the higher downside risk. PSA on Risk Resilience, by 8 points. Risk Resilience is a weighted factor in the composite; position sizing usually responds to it more usefully than the buy/avoid decision does.

What would change the PSA vs SELF verdict?
The result is a state, not a forecast, so it changes when the underlying evidence changes.

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.
