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.
2 bullish / 4 bearish / 1 neutral, conflicted
- Death Cross Active — bearish, trend, long horizon (6.63%)
- Bollinger Band Squeeze — neutral, volatility, short horizon
- BB Lower Band Breach — bullish, volatility, short horizon
2 bullish / 2 bearish, conflicted
- Golden Cross Active — bullish, trend, long horizon (6.60%)
- Keltner Channel Breakdown — bearish, volatility, short horizon
- RSI Oversold - Potential Bounce — bullish, momentum, short horizon
AOS 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.
Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +1.2%, AIQ 0 points).
Price is up while the AIQ Score moved down 2 points over the same session — price and model disagree (price +0.86%, AIQ -2 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.
- 1AYI closes the Momentum gap — currently 7 points behind, the largest single contributor to AOS's edge.
- 2AYI's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it.
- 3AOS's conflicting signal state resolves bearish — it currently carries 2 bullish and 4 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 is better, AOS or AYI?
On the Algovestiq AIQ Score, AOS is the stronger of the two as of Sep 11, 2026, scoring 56 against AYI's 53. The edge comes from momentum and quality. This is a systematic score, not a recommendation: it ranks the two on the same evidence, it does not know your holding period or tax position.
Is AOS or AYI the better buy right now?
AOS carries the stronger systematic profile as of Sep 11, 2026, and the comparison is rated Fragile — 1 of 6 covered evidence groups agree. A Fragile rating means the conclusion is sensitive: the AIQ gap is narrow at 3 points. Treat the lead as provisional.
Why does the AIQ Score favor AOS over AYI?
The composite weights Quality, Value, Momentum and Risk Resilience. AOS leads Momentum by 7 points; AOS leads Quality by 4 points. Where the two split, the factor with the larger weight carries the result.
Which has more analyst upside, AOS or AYI?
Analyst price targets imply +28.7% upside for AOS and +26.8% for AYI, so the Street currently favors AOS. The model and the Street agree here, which is a broader base of evidence than either alone. Analyst targets are expectations, not predictions, and dispersion matters as much as the midpoint.
Which is better value, AOS or AYI?
Neither name separates on the peer-relative Value factor. The two are level on Value. The Value factor reads valuation relative to sector peers and to the company's own fundamental quality, so it is not the same as simply having the lower multiple.
Which has stronger growth, AOS or AYI?
AYI on combined revenue and EPS growth. Growth here is measured on reported revenue and earnings, not on forward estimates — it describes what the businesses have delivered, not what the Street expects next.
Which has stronger momentum, AOS or AYI?
AOS on the Momentum factor, by 7 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, AOS or AYI?
AYI is the more resilient of the two, so the other name carries the higher downside risk. AYI carries the lower 1-month annualized volatility. Risk Resilience is a weighted factor in the composite; position sizing usually responds to it more usefully than the buy/avoid decision does.
Is AOS more profitable than AYI?
The profitability evidence is mixed: gross margin 38.6% vs 49.3%; operating margin 17.6% vs 14.5%; ttm roe 27% vs 16.9%. AOS leads on two measures and AYI on one measure, and there is no single profitability composite that resolves the split — which of the two reads as "more profitable" depends on whether you weight pricing power or operating leverage.
Is AOS's lead over AYI getting stronger or weaker?
AOS lead: Stable — the AIQ differential has held near 3 points over 30 sessions. This is measured from 119 daily comparison snapshots between 2026-05-04 and 2026-09-10. The lead has changed hands 8 times in that window, most recently on 2026-08-19, when AOS moved ahead of AYI.
What would change the AOS vs AYI verdict?
The result is a state, not a forecast, so it changes when the underlying evidence changes. Concretely: AYI closes the Momentum gap — currently 7 points behind, the largest single contributor to AOS's edge; AYI's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it; AOS's conflicting signal state resolves bearish — it currently carries 2 bullish and 4 bearish rules at once; a 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.
What do the current signals say about AOS and AYI?
AOS: 2 bullish / 4 bearish / 1 neutral, conflicted. AYI: 2 bullish / 2 bearish, 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. The most decision-relevant rule on AOS is Death Cross Active (bearish, long horizon). On AYI it is Golden Cross Active (bullish, long horizon).

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.
