What this list is

How the list is built

Each weight is the share of net assets the issuer’s own daily file gives, largest first. Cash and other net assets are in their own row and are not a position. A negative weight is a short or an offsetting contract. Where a source leaves out a ticker, ETFIQ fills it from the same security in another fund’s book; names are set in title case where the source used capitals. How books are read.

Weights are as the source states them, largest first.
