The central trade-off

ARM (Arm Holdings plc American Depositary Shares): the counter-case, on analyst expectations — but at materially higher volatility, 62.8% against 43.4%.

The AIQ Score and Wall Street therefore point in different directions on this pair.

AIQ vs Wall Street

The model and the Street disagree here: AIQ favors MU, analyst targets favor ARM. That disagreement is the most useful thing on this page.

Target dispersion+106.1%+156.1%Lower is tighter analyst agreement
ConsensusBuyBuyContext, not a primary driver

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.

  • Analyst targets on the leader are widely dispersed. (argues the conclusion is provisional)

Stability combines the score gap, how broadly the evidence agrees, how steady the lead has been across daily snapshots, the current signal state on both names, and analyst dispersion on MU.

Price vs model alignment

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

ARMDivergence

Price is up while the AIQ Score moved down 1 points over the same session — price and model disagree (price +2.5%, AIQ -1 points).

MUNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +1.96%, 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. 1ARM closes the Value gap — currently 33 points behind, the largest single contributor to MU's edge.
  2. 2ARM's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it.
  3. 3MU's conflicting signal state resolves bearish — it currently carries 2 bullish and 2 bearish rules at once.
  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.

Which is better, ARM or MU?

On the Algovestiq AIQ Score, MU is the stronger of the two as of Oct 21, 2026, scoring 57 against ARM's 37. The edge comes from value 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 ARM or MU the better buy right now?

MU carries the stronger systematic profile as of Oct 21, 2026, and the comparison is rated Competitive — 4 of 6 covered evidence groups agree. A Competitive rating means the two are close enough that your objective, not the score, should decide.

Why does the AIQ Score favor MU over ARM?

The composite weights Quality, Value, Momentum and Risk Resilience. MU leads Value by 33 points; MU leads Quality by 27 points; MU leads Momentum by 7 points. Where the two split, the factor with the larger weight carries the result.

Which has more analyst upside, ARM or MU?

Analyst price targets imply +62.6% upside for ARM and +58.5% for MU, so the Street currently favors ARM. That points the opposite way to the AIQ Score, which favors MU. 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 MU?

MU is the better-valued of the two on the peer-relative Value factor. MU on the peer-relative Value factor, by 33 points. 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 MU?

MU 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 MU?

MU 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, ARM or MU?

MU is the more resilient of the two, so the other name carries the higher downside risk. MU 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 ARM more profitable than MU?

The profitability evidence is mixed: gross margin 95.3% vs 80.7%; operating margin 17.3% vs 75%; ttm roe 13% vs 91.8%. ARM leads on one measure and MU 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 MU's lead over ARM getting stronger or weaker?

MU lead: Stable — the AIQ differential has held near 20 points over 30 sessions. This is measured from 120 daily comparison snapshots between 2026-06-21 and 2026-10-20. The lead has not changed hands in that window.

What would change the ARM vs MU verdict?

The result is a state, not a forecast, so it changes when the underlying evidence changes. Concretely: ARM closes the Value gap — currently 33 points behind, the largest single contributor to MU's edge; ARM's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it; MU's conflicting signal state resolves bearish — it currently carries 2 bullish and 2 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 ARM and MU?

ARM: 2 bullish / 3 bearish / 1 neutral, conflicted. MU: 2 bullish / 2 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 MU 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.
