Fund facts, side by side
Two funds tracking overlapping universes are separated by cost and risk far more than by holdings. Those lead here.
| Measure | SDY | VOO | Why it matters |
|---|---|---|---|
| Expense ratio | 0.35% | 0.03% | Lower is better — it compounds against you every year you hold. |
| Holdings | 158 | 508 | More holdings means broader diversification, not better returns. |
| Average volume | 208,470 | 7,814,237 | Liquidity — matters most if you trade size. |
| Annualized volatility | 10.8% | 12.8% | Lower is a steadier ride for the same exposure. |
| Max drawdown (1Y) | -8% | -9.2% | The worst peak-to-trough loss over the past year. |
| Sharpe ratio | 0.75 | 0.91 | Return per unit of risk. Higher is better. |
| Beta | 0.23 | 1.00 | Sensitivity to the broad market. Neither direction is better — it depends on the role in your portfolio. |

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 -0.07%, AIQ 0 points).
Price and the AIQ Score both moved up over the latest session (price +0.55%, AIQ +4 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.
- 1SDY closes the Quality gap — currently 23 points behind, the largest single contributor to VOO's edge.
- 2SDY's BB Upper Band Breach resolves — a bearish volatility rule currently active against it.
- 3VOO's conflicting signal state resolves bearish — it currently carries 4 bullish and 1 bearish rules at once.
- 4The narrowing continues — the lead has already given back 14 points over 30 sessions, and a further 1-point move would eliminate VOO's advantage entirely.

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.
