Overview

• Deutsche Börse’s ISS Stoxx confirmed that Porsche AG and Sartorius will exit the DAX and move to the MDAX, with GEA and Scout24 joining the blue-chip index on 22 September.
• ETFs that track the DAX must implement the changes on the effective date, likely generating one‑day selling in the leavers and buy flows into the entrants.
• Porsche’s stock has fallen from a €82.50 IPO price and peaks near €120 to about €45, reflecting weaker sales, EV challenges and margin erosion.
• CEO Oliver Blume attributed the exclusion to Porsche’s comparatively low free float of roughly 12% under the index rules and said he aims for a prompt return.
• The reshuffle follows a 2.3% drop in the DAX as investors weigh US tariffs, geopolitical tensions, higher bond yields and uncertainty over central‑bank policy.
