AIQ vs Wall Street
The model and the Street disagree here: AIQ favors SLAB, analyst targets favor POWI. That disagreement is the most useful thing on this page.
| Measure | POWI | SLAB | Note |
|---|---|---|---|
| Implied upside to target | +62.6% | +4.8% | POWI has more room |
| Target dispersion | +11.8% | 0% | Lower is tighter analyst agreement |
| Consensus | Buy | Hold | Context, not a primary driver |
| Analysts covering | 2 | 1 | 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.

- 2POWI's ATR Expansion - Breakout Mode turns directional — it is neutral today and would confirm a change in trend.
- 3SLAB's Golden Cross Active breaks down — it is the strongest rule currently supporting the verdict.
- 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.

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.
