Two funds tracking overlapping universes are separated by cost and risk far more than by holdings. Those lead here.
| Measure | SPY | SRLN | Why it matters |
|---|---|---|---|
| Expense ratio | 0.09% | 0.7% | Lower is better — it compounds against you every year you hold. |
| Holdings | 505 | 717 | More holdings means broader diversification, not better returns. |
| Average volume | 46,128,904 | 1,936,474 | Liquidity — matters most if you trade size. |
| Annualized volatility | 12.8% | 3.5% | Lower is a steadier ride for the same exposure. |
| Max drawdown (1Y) | -9.1% | -4.7% | The worst peak-to-trough loss over the past year. |
| Sharpe ratio | 0.91 | -1.99 | Return per unit of risk. Higher is better. |
| Beta | 1.00 | 0.14 | 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.
4 bullish / 1 bearish / 1 neutral, conflicted
Only SPY
- Golden Cross Active — bullish, trend, long horizon (5.84%)
- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon
- 52-Week High Proximity — bullish, risk, long horizon (1.2%)
- Uptrend Structure Active — bullish, trend, long horizon
1 bullish / 5 bearish / 1 neutral, conflicted
Only SRLN
- Death Cross Active — bearish, trend, long horizon (0.00%)
- Keltner Channel Breakdown — bearish, volatility, short horizon
- RSI Oversold - Potential Bounce — bullish, momentum, short horizon
- 52-Week Low Proximity — bearish, risk, long horizon (1.2%)
- Downtrend Structure Active — bearish, trend, long horizon
Both carry 2 more signals that do not separate them: ATR Contraction - Coiling, MACD Bearish Crossover.
SPY 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 and the AIQ Score both moved up over the latest session (price +0.53%, AIQ +4 points).
Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.05%, 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.
- 1SRLN closes the Momentum gap — currently 38 points behind, the largest single contributor to SPY's edge.
- 2SRLN's Death Cross Active resolves — a bearish trend rule currently active against it.
- 3SPY's conflicting signal state resolves bearish — it currently carries 4 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.
