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.

AOSConflicted

1 bullish / 2 bearish, conflicted

Only AOS

  • Death Cross Active — bearish, trend, long horizon (7.69%)
  • RSI Overbought — bearish, momentum, short horizon
AYI

3 bullish / 0 bearish

Only AYI

  • Golden Cross Active — bullish, trend, long horizon (2.05%)
  • Uptrend Structure Active — bullish, trend, long horizon

Both carry 1 more signal that do not separate them: MACD Bullish Crossover.

AOS is conflicted, so the timing case there is weaker than the score alone suggests.

Price vs model alignment

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

AOSConfirmed weakness

Price and the AIQ Score both moved down over the latest session (price -0.66%, AIQ -1 points).

AYIConfirmed weakness

Price and the AIQ Score both moved down over the latest session (price -2.82%, AIQ -1 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. 1AOS closes the Momentum gap — currently 13 points behind, the largest single contributor to AYI's edge.
  2. 2AOS's Death Cross Active resolves — a bearish trend rule currently active against it.
  3. 3AYI'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.

Straight answers

Each answer is regenerated from the current snapshot, not written once and left to age.

Which is better, AOS or AYI?

On the Algovestiq AIQ Score, AYI is the stronger of the two as of Oct 31, 2026, scoring 70 against AOS's 68. The edge comes from momentum. AOS is not without a case — it holds the better quality profile, which matters more if that is the objective you are optimizing for. 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?

AYI carries the stronger systematic profile as of Oct 31, 2026, and the comparison is rated Fragile — 2 of 6 covered evidence groups agree. A Fragile rating means the conclusion is sensitive: the AIQ gap is narrow at 2 points. Treat the lead as provisional.

Why does the AIQ Score favor AYI over AOS?

The composite weights Quality, Value, Momentum and Risk Resilience. AYI leads Momentum by 13 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 +10.7% upside for AOS and +23.4% for AYI, so the Street currently favors AYI. 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?

AYI on the Momentum factor, by 13 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 AYI's lead over AOS getting stronger or weaker?

AYI lead: Stable — the AIQ differential has held near 2 points over 30 sessions. This is measured from 120 daily comparison snapshots between 2026-06-29 and 2026-10-28. The lead has changed hands 3 times in that window, most recently on 2026-10-23, when AYI moved ahead of AOS.

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: AOS closes the Momentum gap — currently 13 points behind, the largest single contributor to AYI's edge; AOS's Death Cross Active resolves — a bearish trend rule currently active against it; AYI's Golden Cross Active breaks down — it is the strongest rule currently supporting the verdict; 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: 1 bullish / 2 bearish, conflicted. AYI: 3 bullish / 0 bearish. 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.
