Equal weighted. Membership is recalculated nightly from end-of-day data: active US common stocks in the Healthcare sector with a market cap of at least USD 1 billion and a 90-day average daily value traded of at least USD 5 million, ranked by market cap, top 20. The published index is equal-weighted, tracking the typical stock; a market-cap-weighted companion line (capped at 20% per stock) is shown for comparison. The gap between the two is a participation gauge, not a forecast.
