AIQ vs Wall Street
The model and the Street disagree here: AIQ favors AIG, analyst targets favor AON. That disagreement is the most useful thing on this page.
| Measure | AIG | AON | Note |
|---|---|---|---|
| Implied upside to target | +15.3% | +28.5% | AON has more room |
| Target dispersion | +20.7% | +24.7% | Lower is tighter analyst agreement |
| Consensus | Hold | Buy | Context, not a primary driver |
| Analysts covering | 8 | 10 | 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 (0.68%)
- Bollinger Band Squeeze — neutral, volatility, short horizon
- MACD Bearish Crossover — bearish, momentum, short horizon
2 bullish / 3 bearish, conflicted
- Golden Cross Active — bullish, trend, long horizon (4.53%)
- Keltner Channel Breakdown — bearish, volatility, short horizon
- RSI Oversold - Potential Bounce — bullish, momentum, short horizon
AIG leads the comparison while carrying a conflicted signal state, which is one reason the stability rating is not higher.

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.
- 1AON closes the Value gap — currently 29 points behind, the largest single contributor to AIG's edge.
- 2AON's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it.
- 3AIG's conflicting signal state resolves bearish — it currently carries 1 bullish and 1 bearish rules at once.
- 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.
