| Measure | SNDK | SPY | Note |
|---|---|---|---|
| Implied upside to target | +21% | — | Level |
| Target dispersion | +122% | — | Lower is tighter analyst agreement |
| Consensus | Buy | — | Context, not a primary driver |

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.
3 bullish / 0 bearish / 1 neutral
- Golden Cross Active — bullish, trend, long horizon (60.39%)
- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (8.73%)
4 bullish / 1 bearish / 1 neutral, conflicted
- Golden Cross Active — bullish, trend, long horizon (6.20%)
- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon
- 52-Week High Proximity — bullish, risk, long horizon (1.9%)
SPY 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.
Price is up while the AIQ Score moved down 1 points over the same session — price and model disagree (price +0.28%, AIQ -1 points).
Price is up while the AIQ Score moved down 2 points over the same session — price and model disagree (price +0.5%, AIQ -2 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.
- 1SPY closes the Momentum gap — currently 26 points behind, the largest single contributor to SNDK's edge.
- 2SPY generates a confirmed bullish trend signal it does not currently carry, such as MACD Bullish Crossover.
- 3SNDK's Golden Cross Active breaks down — it is the strongest rule currently supporting the verdict.
- 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.
