|---|---|---|---|
| Expense ratio | 0.04% | 0.03% | Lower is better — it compounds against you every year you hold. |

| Sharpe ratio | -3.34 | 0.86 | Return per unit of risk. Higher is better. |

What would flip this result

- 1SPSB closes the Risk Resilience gap — currently 13 points behind, the largest single contributor to VTI's edge.
- 2SPSB's Death Cross Active resolves — a bearish trend rule currently active against it.
- 3VTI's conflicting signal state resolves bearish — it currently carries 2 bullish and 1 bearish rules at once.
- 4The narrowing continues — the lead has already given back 5 points over 30 sessions, and a further 7-point move would eliminate VTI'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.
