AIQ vs Wall Street
The model and the Street disagree here: AIQ favors COLB, analyst targets favor EBC. That disagreement is the most useful thing on this page.
| Measure | COLB | EBC | Note |
|---|---|---|---|
| Implied upside to target | +9.8% | +13.9% | EBC has more room |
| Target dispersion | +14.8% | +11.8% | Lower is tighter analyst agreement |
| Consensus | Buy | Buy | Context, not a primary driver |
| Analysts covering | 5 | 5 | 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 (6.39%)
- Bollinger Band Squeeze — neutral, volatility, short horizon
- MACD Bearish Crossover — bearish, momentum, short horizon

- Bollinger Band Squeeze — neutral, volatility, short horizon
- RSI Oversold - Potential Bounce — bullish, momentum, short horizon

- 2EBC's Bollinger Band Squeeze turns directional — it is neutral today and would confirm a change in trend.
- 3COLB's conflicting signal state resolves bearish — it currently carries 1 bullish and 1 bearish rules at once.
- 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.
