AIQ vs Wall Street
The model and the Street disagree here: AIQ favors ATO, analyst targets favor CMS. That disagreement is the most useful thing on this page.
| Measure | ATO | CMS | Note |
|---|---|---|---|
| Implied upside to target | +15.3% | +20.6% | CMS has more room |
| Target dispersion | +11.2% | +14.8% | Lower is tighter analyst agreement |
| Consensus | Hold | Buy | Context, not a primary driver |
| Analysts covering | 6 | 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.

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 / 3 bearish / 1 neutral, conflicted
- Death Cross Active — bearish, trend, long horizon (1.76%)
- Bollinger Band Squeeze — neutral, volatility, short horizon

- Death Cross Active — bearish, trend, long horizon (2.32%)
- Bollinger Band Squeeze — neutral, volatility, short horizon
- 52-Week Low Proximity — bearish, risk, long horizon (0.7%)
ATO leads the comparison while carrying a conflicted signal state, which is one reason the stability rating is not higher.
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 -0.98%, AIQ 0 points).
Price is down while the AIQ Score moved up 1 points over the same session — price and model disagree (price -0.78%, AIQ +1 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.
- 1CMS closes the Quality gap — currently 16 points behind, the largest single contributor to ATO's edge.
- 2CMS's Death Cross Active resolves — a bearish trend rule currently active against it.
- 3ATO's conflicting signal state resolves bearish — it currently carries 1 bullish and 3 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.

Which has stronger momentum, ATO or CMS?
The two are level on Momentum. Momentum is one of the four weighted factors in the AIQ composite. It has documented persistence over three- to twelve-month horizons, which makes it a timing input rather than a reason to hold something indefinitely.

What would change the ATO vs CMS verdict?
The result is a state, not a forecast, so it changes when the underlying evidence changes.

What do the current signals say about ATO and CMS?
ATO: 1 bullish / 3 bearish / 1 neutral, conflicted. CMS: 1 bullish / 3 bearish / 1 neutral, conflicted. A conflicted state means bullish and bearish rules are active on the same name at once — the technical evidence is not pointing one way, and a decision taken on it carries more timing risk.

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.
