Is it redundant to hold both SMH and RSP?
Out of every $100 split evenly between them, about $4 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 6 names only in SMH, 485 only in RSP. Half in each behaves like 48 equally weighted stocks, against 13 for SMH alone and 497 for RSP alone. Whether that duplication is a problem depends on the mix you want; 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 Invesco 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.
