Overview

• Deutsche Börse confirmed on 3 September that Porsche AG and Sartorius will exit the DAX and join the MDax, while GEA and Scout24 enter the blue-chip index effective 22 September.
• Porsche SE, the holding company controlled by the Porsche and Piëch families, remains in the DAX, underscoring the distinction from the operating automaker Porsche AG.
• The reshuffle reflects DAX rules that prioritize free‑float market value and trading turnover, with Porsche's eligibility weakened by a sharp share-price decline since its 2022 IPO.
• Analysts note the stock’s slide has been driven by softer demand in China, electric‑vehicle sales challenges and trade frictions, which have eroded valuation.
• Index‑tracking ETFs and benchmarked funds are expected to rebalance around the effective date, a pattern that can pressure outgoing stocks and spark near‑term volatility.
