IVV and RSP: what people ask

questions4 answered

How much do IVV and RSP overlap?

44% by weight, as of October 14, 2026: moderate overlap. 503 companies appear in both funds; they make up 100% of IVV and 100% of RSP.

Which stocks do IVV and RSP both hold?

The largest shared positions are CRWD, PLTR, TJX, ABBV and META. Ranked by the smaller of the two weights, which is the part you would own twice.

Is it redundant to hold both IVV and RSP?

Out of every $100 split evenly between them, about $44 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 1 names only in IVV, 2 only in RSP. Half in each behaves like 139 equally weighted stocks, against 44 for IVV alone and 498 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 iShares 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.
