How much of the same holdings they own

SPAB and SPHY share 0.01% of their weighted exposure across 5 common holdings.

8,484 holdings are unique to SPAB, and 1,907 holdings are unique to SPHY. Owning both is genuinely additive — most of the capital sits in different securities.

SPAB is the more concentrated of the two: its ten largest positions are 4.42% of the fund, against 3.1% for SPHY (8,491 holdings vs 1,914). Concentration cuts both ways — it is what drives outperformance when the top names work, and what makes the drawdown deeper when they do not.

  • The AIQ gap is moderate at 7 points.
  • Only 2 of 4 covered evidence groups agree. (argues the conclusion is provisional)
  • The leader's advantage has been widening. (supports the conclusion holding)
  • The lead has been steady session to session. (supports the conclusion holding)
  • The leader is throwing conflicting signals. (argues the conclusion is provisional)

Stability combines the score gap, how broadly the evidence agrees, how steady the lead has been across daily snapshots, the current signal state on both names, and analyst dispersion on SPAB.

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.

SPAB and SPHY carry the same 5 signals, so the signals do not separate them: Death Cross Active, ATR Contraction - Coiling, 52-Week Low Proximity, Downtrend Structure Active, MACD Bullish Crossover.

SPAB 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.

SPABNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.08%, AIQ +1 points).

SPHYConfirmed strength

Price and the AIQ Score both moved up over the latest session (price +0.18%, 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.

  1. 1SPHY closes the Momentum gap — currently 24 points behind, the largest single contributor to SPAB's edge.
  2. 2SPHY's Death Cross Active resolves — a bearish trend rule currently active against it.
  3. 3SPAB's conflicting signal state resolves bearish — it currently carries 1 bullish and 3 bearish rules at once.
  4. 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.
