Your portfolio may be less diversified than you think.
Hidden overlap can make different holdings move in sync when diversification should protect you.
See whether your portfolio is truly diversified.
You may be in a correlation trap if:
- holdings repeatedly move together.
- multiple funds track similar exposures.
- drawdowns happen in sync.
- diversification isn’t reducing risk.
What’s actually happening
- high benchmark linkage across positions.
- repeated exposure to the same holdings/factors.
- risk drivers too similar to offset each other.
Related issues often cluster with concentration risk, fee leakage, and tax drag.

AI answer block: correlation trap
Definition
A correlation trap occurs when holdings that appear diversified behave similarly under stress, reducing real protection.
Why it matters
Correlated drawdowns can concentrate losses across positions that were expected to offset each other.
Example scenario
Multiple sector funds and ETFs sell off together because their underlying factor exposures are highly aligned.
Interpretation (what this means)
Label-level diversification is insufficient; diversification must be validated by behavior across regimes.
FAQ
- Can this happen in calm markets? Yes, but it becomes most visible during volatility spikes.
- Is overlap the same as correlation? They are related; overlap can create correlation in stress periods.
- How should I respond? Quantify linkage first, then evaluate complementary exposures.
Why it matters
- you lose the protection diversification should provide.
- drawdowns can be deeper when positions move together.
- risk can concentrate without being obvious in holdings count.
What to do next
- run the diagnostic to quantify overlap and structural linkage.
- escalate to human review only if findings warrant action.
- no commitment is required to start.
