Sources

Members and weights come from the Xtrackers Switzerland UCITS ETF (SMI) holdings (source), as of 2026-10-26. This is an ETF's holdings file, so the weights are the fund's portfolio weights and can differ slightly from the official index weights.

The official SMI is calculated by SIX. See the methodology for what differs from the official list.
