The story
On Nov 4, 2026, the STOXX 600 was up nearly 1% by 3:27 AM CT (Central Time) after its futures fell as much as 1.4% early, per Reuters. European markets trade while US futures are still in their overnight session, so they're the first big market after Asia to react to US news.
Why markets watch it
It's the broadest single gauge of European stocks.
