The central trade-off
SMTC (Semtech Corporation): the stronger current systematic profile, led by quality and momentum.
STM (STMicroelectronics N.V.): the counter-case, on risk resilience, value, valuation.
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 SMTC, analyst targets favor STM. That disagreement is the most useful thing on this page.
| Measure | SMTC | STM | Note |
|---|---|---|---|
| Implied upside to target | +26.7% | +39.8% | STM has more room |
| Target dispersion | +106.7% | +71.2% | Lower is tighter analyst agreement |
| Consensus | Buy | Buy | Context, not a primary driver |
| Analysts covering | 14 | 8 | 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.

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.
- 1STM closes the Quality gap — currently 23 points behind, the largest single contributor to SMTC's edge.
- 2STM's ATR Expansion - Breakout Mode turns directional — it is neutral today and would confirm a change in trend.
- 3SMTC's Golden Cross Active breaks down — it is the strongest rule currently supporting the verdict.
- 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.
