| Measure | XBI | XLC | Why it matters |
|---|---|---|---|
| Expense ratio | 0.35% | 0.08% | Lower is better — it compounds against you every year you hold. |
| Holdings | 156 | 27 | More holdings means broader diversification, not better returns. |
| Average volume | 9,003,461 | 5,977,128 | Liquidity — matters most if you trade size. |
| Annualized volatility | 29.1% | 16.3% | Lower is a steadier ride for the same exposure. |
| Max drawdown (1Y) | -14.9% | -14.1% | The worst peak-to-trough loss over the past year. |
| Sharpe ratio | 1.19 | -0.92 | Return per unit of risk. Higher is better. |
| Beta | 1.08 | 0.68 | Sensitivity to the broad market. Neither direction is better — it depends on the role in your portfolio. |

What would flip this result

- 2XLC's Death Cross Active resolves — a bearish trend rule currently active against it.
- 3XBI's Golden Cross Active breaks down — it is the strongest rule currently supporting the verdict.
- 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.

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.
