Source: publicly available daily prices. The universe is today's index membership, so names that appreciated over the period are over-represented and the spreads carry survivorship bias.

Monthly issues are published on the first Monday, on data through the prior month-end. Next release: 2 November 2026. The Note closes with its methodology note and document details.

The note is general research of regular circulation. No securities are referenced as opportunities, and nothing in it is tailored to any recipient.
