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 | VOO | SOXX | Why it matters |
|---|---|---|---|
| Expense ratio | 0.03% | 0.33% | Lower is better — it compounds against you every year you hold. |
| Holdings | 508 | 33 | More holdings means broader diversification, not better returns. |
| Average volume | 6,986,663 | 8,795,259 | Liquidity — matters most if you trade size. |
| Annualized volatility | 12.7% | 46.6% | Lower is a steadier ride for the same exposure. |
| Max drawdown (1Y) | -9.2% | -29% | The worst peak-to-trough loss over the past year. |
| Sharpe ratio | 0.68 | 1.31 | Return per unit of risk. Higher is better. |
| Beta | 1.00 | 2.67 | Sensitivity to the broad market. Neither direction is better — it depends on the role in your portfolio. |

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.

Only VOO
- ATR Contraction - Coiling — neutral, volatility, short horizon (0.90%)
- EMA Ribbon Compression — neutral, trend, medium horizon

Only SOXX
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (3.52%)

VOO leads the comparison while carrying a conflicted signal state, which is one reason the stability rating is not higher.
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 -1.77%, AIQ 0 points).
Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price -8.24%, AIQ 0 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.
- 1SOXX closes the Risk Resilience gap — currently 73 points behind, the largest single contributor to VOO's edge.
- 2SOXX's MACD Bearish Crossover resolves — a bearish momentum rule currently active against it.
- 3VOO's conflicting signal state resolves bearish — it currently carries 3 bullish and 1 bearish rules at once.
- 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.
How to use side-by-side comparison →This comparison is informational and educational, not investment advice. AIQ scores update daily; re-check after earnings, guidance or macro data that materially changes either name’s factor profile.
