AIQ vs Wall Street
The model and the Street disagree here: AIQ favors PDM, analyst targets favor SLG. That disagreement is the most useful thing on this page.
| Measure | PDM | SLG | Note |
|---|---|---|---|
| Implied upside to target | +13.5% | +23.9% | SLG has more room |
| Target dispersion | +9.5% | +57.1% | Lower is tighter analyst agreement |
| Consensus | Hold | Buy | Context, not a primary driver |
| Analysts covering | 2 | 9 | 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 / 0 bearish
Only PDM
- MACD Bullish Crossover — bullish, momentum, short horizon
1 bullish / 1 bearish / 2 neutral, conflicted
Only SLG
- Bollinger Band Squeeze — neutral, volatility, short horizon
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (3.79%)
- MACD Bearish Crossover — bearish, momentum, short horizon
Both carry 1 more signal that do not separate them: Golden Cross Active.
SLG 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.
Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price 0%, AIQ +1 points).
Price is down while the AIQ Score moved up 4 points over the same session — price and model disagree (price -0.72%, AIQ +4 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.
- 1SLG closes the Momentum gap — currently 16 points behind, the largest single contributor to PDM's edge.
- 2SLG's Bollinger Band Squeeze turns directional — it is neutral today and would confirm a change in trend.
- 3PDM'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.
