AIQ vs Wall Street
The model and the Street disagree here: AIQ favors POWI, analyst targets favor ONTO. That disagreement is the most useful thing on this page.
| Measure | ONTO | POWI | Note |
|---|---|---|---|
| Implied upside to target | +71.2% | +67.2% | ONTO has more room |
| Target dispersion | +31.6% | +22.3% | Lower is tighter analyst agreement |
| Consensus | Buy | Buy | Context, not a primary driver |
| Analysts covering | 9 | 3 | 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 / 2 bearish / 1 neutral, conflicted
Only ONTO
- Golden Cross Active — bullish, trend, long horizon (8.67%)
- Keltner Channel Breakdown — bearish, volatility, short horizon
- RSI Oversold - Potential Bounce — bullish, momentum, short horizon
0 bullish / 3 bearish / 1 neutral
Only POWI
- Death Cross Active — bearish, trend, long horizon (12.60%)
- Downtrend Structure Active — bearish, trend, long horizon
Both carry 2 more signals that do not separate them: ATR Expansion - Breakout Mode, MACD Bearish Crossover.
ONTO 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 +1.15%, AIQ 0 points).
Price and the AIQ Score both moved up over the latest session (price +2.73%, 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.
- 1ONTO closes the Momentum gap — currently 20 points behind, the largest single contributor to POWI's edge.
- 2ONTO's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it.
- 3POWI starts generating bearish momentum or trend signals.
- 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, ONTO or POWI?
POWI on the Momentum factor, by 20 points. 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.

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.
