STOXX 600 rises 0.84% to 641.13 in preliminary close

Broad-based European equity strength, with the euro-zone blue-chip gauge outpacing the wider STOXX 600, points to large-cap leadership rather than a narrow rally. The dispersion between top gainers like Genmab and laggards such as EssilorLuxottica and Santander shows sector and stock-specific rotation is doing much of the work beneath the headline move. Whether this breadth holds—and whether the STOXX 50's outperformance persists relative to the broader index—is the open question worth watching.
