None. SMH and XLI have no holding in common.
Is it redundant to hold both SMH and XLI?
No. Out of every $100 split evenly between them, none buys the same company. Half in each gives you 108 different holdings that behave like 39 equally weighted stocks, against 13 for SMH alone and 41 for XLI alone. Whether that mix suits you depends on what you want to own; this is a description, not advice.
How is ETF overlap calculated here?
For every company held by both funds we take the smaller of its two weights and add them up. The weights come from the full holdings files VanEck and SPDR publish, not a top-10 sample, and companies are matched by their ISIN so share classes stay apart. Sector overlap applies the same rule to the issuers' sector labels; "behaves like N equally weighted stocks" is one over the sum of the squared weights.
Weights come from each issuer's published holdings file and are matched company by company on their ISIN. Cash, futures and currency positions are left out. This page describes what the funds hold; it is not investment advice.
