Holdings overlap
Weighted overlap is the sum, over the securities both funds hold, of the smaller of the two weights. 0% means no shared holdings; 100% means identical portfolios.

How overlap is measured
Each fund's latest public Form N-PORT report lists its positions with the percent of net assets each one makes up. For every security both funds hold, the smaller of its two weights is counted, and those are added up. If fund A holds a stock at 6% and fund B at 4%, that stock adds 4 percentage points.
Securities are matched by ISIN first, then by CUSIP (a US or Canadian ISIN contains the CUSIP), and only as a last resort by issuer name, for non-debt holdings where one fund gives no identifier. Repeated lines of the same security in one fund are added together, and each security is matched once.
Cash funds, repurchase agreements, derivative contracts and short positions are left out because their reported value is not comparable exposure. For funds with more than 2,000 positions only the largest 2,000 are stored, so the result is a lower bound and the possible extra is shown. Reports can be for different month ends, and funds trade between reports.
The count-based shares show how many of one fund's holdings the other also holds, which can be high even when overlap by weight is low. Read more in where the ETF data comes from.
