The central trade-off
ACMR (ACM Research, Inc.): the stronger current systematic profile, led by quality and value.
AAOI (Applied Optoelectronics, Inc.): the counter-case, on analyst expectations — but at materially higher volatility, 109.6% against 61.7%.
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 ACMR, analyst targets favor AAOI. That disagreement is the most useful thing on this page.
| Measure | AAOI | ACMR | Note |
|---|---|---|---|
| Implied upside to target | +60.9% | +49.1% | AAOI has more room |
| Target dispersion | +23% | +55% | Lower is tighter analyst agreement |
| Consensus | Buy | Buy | Context, not a primary driver |
| Analysts covering | 2 | 5 | 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.
2 bullish / 2 bearish / 1 neutral, conflicted
- Golden Cross Active — bullish, trend, long horizon (15.88%)
- RSI Oversold - Potential Bounce — bullish, momentum, short horizon
- Beta Spike Warning — bearish, risk, long horizon
1 bullish / 2 bearish / 1 neutral, conflicted
- Golden Cross Active — bullish, trend, long horizon (35.72%)
- Beta Spike Warning — bearish, risk, long horizon
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (7.27%)
ACMR 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 +5.13%, AIQ 0 points).
Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +7.23%, 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.
- 1AAOI closes the Quality gap — currently 15 points behind, the largest single contributor to ACMR's edge.
- 2AAOI's Beta Spike Warning resolves — a bearish risk rule currently active against it.
- 3ACMR's conflicting signal state resolves bearish — it currently carries 1 bullish and 2 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.

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.
