How much of the same holdings they own

AGG and IEF share 4.92% of their weighted exposure across 16 common holdings.

13,344 holdings are unique to AGG, and every IEF holding is also in AGG. Owning both is genuinely additive — most of the capital sits in different securities.

IEF is the more concentrated of the two: its ten largest positions are 84.78% of the fund, against 3.79% for AGG (18 holdings vs 13,395). Concentration cuts both ways — it is what drives outperformance when the top names work, and what makes the drawdown deeper when they do not.

AIQ Decision Stability

Fragile

The conclusion is sensitive to small changes. Treat the lead as provisional and watch the flip conditions below.

  • The AIQ gap is narrow at 2 points. (argues the conclusion is provisional)
  • Only 1 of 4 covered evidence groups agree. (argues the conclusion is provisional)
  • 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 AGG.

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.

AGG and IEF carry the same 6 signals, so the signals do not separate them: Bollinger Band Squeeze, Death Cross Active, ATR Contraction - Coiling, 52-Week Low Proximity, Downtrend Structure Active, MACD Bullish Crossover.

AGG 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.

AGGNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.03%, AIQ +1 points).

IEFNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price -0.02%, 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. 1IEF closes the Risk Resilience gap — currently 6 points behind, the largest single contributor to AGG's edge.
  2. 2IEF's Death Cross Active resolves — a bearish trend rule currently active against it.
  3. 3AGG'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.
