AIQ vs Wall Street
The model and the Street disagree here: AIQ favors KLAC, analyst targets favor ARM. That disagreement is the most useful thing on this page.
| Measure | ARM | KLAC | Note |
|---|---|---|---|
| Implied upside to target | +54.7% | +29.9% | ARM has more room |
| Target dispersion | +119.4% | +69.7% | Lower is tighter analyst agreement |
| Consensus | Buy | Buy | Context, not a primary driver |
| Analysts covering | 12 | 17 | Higher coverage generally improves confidence |
The two are measuring different things. The AIQ Score reads current fundamentals, valuation, trend and risk; analyst targets price forward expectations. A divergence of this kind is either a contrarian opportunity or a sign the model is missing something already priced in — it is worth resolving before acting on either.
Analyst targets are expectations, not predictions. Dispersion matters as much as the midpoint.

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.
1 bullish / 2 bearish / 1 neutral, conflicted
- Golden Cross Active — bullish, trend, long horizon (42.10%)
- Beta Spike Warning — bearish, risk, long horizon
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (7.37%)

- Golden Cross Active — bullish, trend, long horizon (24.46%)
- RSI Oversold - Potential Bounce — bullish, momentum, short horizon
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (5.47%)
KLAC 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 -0.62%, AIQ 0 points).
Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.14%, 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.
- 1ARM closes the Quality gap — currently 12 points behind, the largest single contributor to KLAC's edge.
- 2ARM's Beta Spike Warning resolves — a bearish risk rule currently active against it.
- 3KLAC's conflicting signal state resolves bearish — it currently carries 2 bullish and 1 bearish rules at once.
- 4A regime shift changes factor weighting — the composite weights Quality and Value at 30% each, so a rotation toward either would move the result most.

Which is better, ARM or KLAC?
On the Algovestiq AIQ Score, KLAC is the stronger of the two as of Sep 2, 2026, scoring 47 against ARM's 43. The edge comes from quality and risk resilience. ARM is not without a case — it holds the better momentum 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 ARM or KLAC the better buy right now?
KLAC carries the stronger systematic profile as of Sep 2, 2026, and the comparison is rated Fragile — 3 of 6 covered evidence groups agree. A Fragile rating means the conclusion is sensitive: the AIQ gap is narrow at 4 points. Treat the lead as provisional.
Why does the AIQ Score favor KLAC over ARM?
The composite weights Quality at 30%, Value at 30%, Momentum at 25% and Risk Resilience at 15%. KLAC leads Quality by 12 points; ARM leads Momentum by 6 points; KLAC leads Risk Resilience by 6 points. Where the two split, the factor with the larger weight carries the result.
Which has more analyst upside, ARM or KLAC?
Analyst price targets imply +54.7% upside for ARM and +29.9% for KLAC, so the Street currently favors ARM. That points the opposite way to the AIQ Score, which favors KLAC. The two are measuring different things: the model reads current fundamentals, valuation, trend and risk; the Street is pricing forward expectations. A divergence of this kind is either a contrarian opportunity or a sign the model is missing something the analysts have already priced — it is the single most useful row on this page to investigate. Analyst targets are expectations, not predictions, and dispersion matters as much as the midpoint.
Which is better value, ARM or KLAC?
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, ARM or KLAC?
KLAC 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, ARM or KLAC?
ARM on the Momentum factor, by 6 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.
Which is riskier, ARM or KLAC?
KLAC is the more resilient of the two, so the other name carries the higher downside risk. KLAC on Risk Resilience, by 6 points. The Risk Resilience factor weights 15% of the composite; position sizing usually responds to it more usefully than the buy/avoid decision does.
Is ARM more profitable than KLAC?
The profitability evidence is mixed: gross margin 95.3% vs 61.3%; operating margin 17.3% vs 41.7%; roe 13% vs 85.4%. ARM leads on one measure and KLAC on two measures, 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 KLAC's lead over ARM getting stronger or weaker?
KLAC lead: Strengthening — the AIQ differential moved from 0 to 4 points over 30 sessions. This is measured from 120 daily comparison snapshots between 2026-04-20 and 2026-09-01. The lead has changed hands 6 times in that window, most recently on 2026-08-05, when ARM moved ahead of KLAC.
What would change the ARM vs KLAC verdict?
The result is a state, not a forecast, so it changes when the underlying evidence changes. Concretely: ARM closes the Quality gap — currently 12 points behind, the largest single contributor to KLAC's edge; ARM's Beta Spike Warning resolves — a bearish risk rule currently active against it; KLAC's conflicting signal state resolves bearish — it currently carries 2 bullish and 1 bearish rules at once; a regime shift changes factor weighting — the composite weights Quality and Value at 30% each, so a rotation toward either would move the result most.
What do the current signals say about ARM and KLAC?
ARM: 1 bullish / 2 bearish / 1 neutral, conflicted. KLAC: 2 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. The most decision-relevant rule on ARM is Golden Cross Active (bullish, long horizon). On KLAC it is Golden Cross Active (bullish, long horizon).

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.
