iShares MSCI Switzerland ETF (EWL US) – Portfolio Construction Methodology

The underlying MSCI Switzerland 25/50 Index provides free-float market-cap exposure to Swiss large- and mid-cap equities that collectively target ~85% of the Swiss investable universe by free-float market cap. Constituents come from the MSCI Switzerland Standard universe, which applies investability screens (free float, foreign ownership limits, and liquidity metrics) and maintains non-overlapping size segments. Weights start at free-float market cap and are optimized quarterly (Feb/May/Aug/Nov) to meet 25/50 constraints at the group-entity level: no single group entity >25% and the aggregate of >5% positions ≤50%, with a standard 10% buffer applied at rebalance (i.e., 22.5%/45%). The optimization also limits extreme upweights relative to uncapped weights and seeks to minimize tracking error and turnover; corporate actions flow through consistent with MSCI maintenance policies.
