How much do QQQ and VUG overlap?

The weighted-overlap result uses the smaller portfolio weight for each reliably matched shared holding. Review the data timestamp and coverage states with the percentage.

Is QQQ or VUG more diversified?

Diversification cannot be decided from the shared-holding count alone. Compare unique holdings, concentration, sector, country, and market-cap-style exposure together.

Should I own both QQQ and VUG?

That depends on whether the duplicated exposure is intentional. The 50/50 portfolio view shows how much of a combined allocation is shared, but it is not personalized investment advice.

How many holdings do QQQ and VUG share?

QQQ and VUG share 57 reliably matched holdings in the stored snapshots. Check both provider dates and identified coverage before treating the count as complete.

Can AI predict whether QQQ or VUG will perform better?

No. AI cannot predict whether QQQ or VUG will perform better. This page measures current holdings exposure and does not compare future returns or recommend a winner.

Model your whole-portfolio exposure

Enter each ETF as a share of the whole portfolio. Pineify keeps any remainder unmodeled and does not rescale the inputs.

QQQ allocation (%)VUG allocation (%)

0% remains outside this two-ETF model.

Shared exposure: 76.4%; Combined exposure to holdings present in both ETFs.
Duplicate slice: 31.1%; The smaller scaled position for every shared holding.
Unmodeled remainder: 0.0%; Portfolio weight outside the two entered ETFs.

Method

Weighted overlap is the sum of the smaller holding weight for every matched security.
Pineify retains valid ISIN, CUSIP, and symbol aliases. Matching proceeds in stages and only accepts unique, non-conflicting identities. Names are not fuzzy matched.
Common exposure is calculated separately for each ETF. It is not the same metric as weighted overlap.
Negative weights are reported separately and excluded from the long-only overlap calculation.
Market-cap style uses Pineify methodology v1: small below $2 billion, mid from $2 billion to below $10 billion, and large at $10 billion or more. Market-cap data older than seven days is stale and the affected weight remains unclassified.

What this QQQ and VUG result means

Holding count and weight answer different questions

The shared count shows how many resolved holding identities appear on both sides. Weighted overlap shows how much of the smaller position lines up for each shared security.
