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.

  • Some positive holding weight did not have a reliable security identity.
  • Some positive holding weight did not have a reliable security identity.
  • Holding tables show the highest-weight rows; calculations use every resolved holding.
  • The two ETF holdings snapshots have different FMP update times.

What this SMH and SOXX 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.

This is not a performance comparison

The page does not compare fees, liquidity, tracking error, taxes, or historical returns. Use those factors in a separate fund review before making an investment decision.

ETF overlap questions

A next step after overlap

Put the duplicate exposure in research context

ETF overlap explains portfolio composition. Finance Agent can help you inspect the funds, sectors, and holdings behind the result. It does not turn overlap into a buy or sell recommendation.

Pineify ETF Overlap is an information tool, not investment advice. The analysis does not compare fees, liquidity, past performance, or expected returns, and it does not recommend one ETF over another. Data can be incomplete or delayed. No tool or AI system can predict ETF prices or guarantee a return.
