AIQ vs Wall Street
The model and the Street disagree here: AIQ favors FORM, analyst targets favor DIOD. That disagreement is the most useful thing on this page.
| Measure | DIOD | FORM | Note |
|---|---|---|---|
| Implied upside to target | +64.2% | +31.5% | DIOD has more room |
| Target dispersion | +46.2% | +37.7% | Lower is tighter analyst agreement |
| Consensus | Buy | Buy | Context, not a primary driver |
| Analysts covering | 1 | 6 | 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 / 1 bearish / 1 neutral, conflicted
- Golden Cross Active — bullish, trend, long horizon (14.97%)
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (5.52%)
- MACD Bearish Crossover — bearish, momentum, short horizon
3 bullish / 0 bearish / 1 neutral
- Golden Cross Active — bullish, trend, long horizon (8.85%)
- Uptrend Structure Active — bullish, trend, long horizon
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (6.87%)
DIOD is conflicted, so the timing case there is weaker than the score alone suggests.
Price vs model alignment
Whether the latest session's price move confirms what the model did over the same session, or contradicts it.
Price and the AIQ Score both moved up over the latest session (price +3.65%, AIQ +2 points).
Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +2.52%, 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.
- 1DIOD closes the Quality gap — currently 13 points behind, the largest single contributor to FORM's edge.
- 2DIOD's MACD Bearish Crossover resolves — a bearish momentum rule currently active against it.
- 3FORM'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.
