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 | UNG | VTI | Why it matters |
|---|---|---|---|
| Expense ratio | 1.17% | 0.03% | Lower is better — it compounds against you every year you hold. |

| Average volume | 15,240,597 | 3,115,564 | Liquidity — matters most if you trade size. |
| Annualized volatility | 58.7% | 13% | Lower is a steadier ride for the same exposure. |
| Max drawdown (1Y) | -43% | -9.2% | The worst peak-to-trough loss over the past year. |
| Sharpe ratio | 0.02 | 0.86 | Return per unit of risk. Higher is better. |
| Beta | -0.69 | 1.02 | 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.
0 bullish / 2 bearish / 1 neutral
Only UNG
- Bollinger Band Squeeze — neutral, volatility, short horizon
- Death Cross Active — bearish, trend, long horizon (7.32%)
2 bullish / 1 bearish / 2 neutral, conflicted
Only VTI
- Golden Cross Active — bullish, trend, long horizon (5.66%)
- ATR Contraction - Coiling — neutral, volatility, short horizon (0.96%)
- EMA Ribbon Compression — neutral, trend, medium horizon
- 52-Week High Proximity — bullish, risk, long horizon (1.7%)
Both carry 1 more signal that do not separate them: MACD Bearish Crossover.
VTI 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.
Price is down while the AIQ Score moved up 6 points over the same session — price and model disagree (price -5.05%, AIQ +6 points).
Price and the AIQ Score both moved up over the latest session (price +0.55%, AIQ +1 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.
- 1UNG closes the Risk Resilience gap — currently 44 points behind, the largest single contributor to VTI's edge.
- 2UNG'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.
- 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.
