EU chips stock rally on Marvell forecasts spillover, bullish analyst comments

European semiconductor stocks rise in morning trading, helped by a bullish BofA Global Research note and positive sentiment from a U.S. peer's forecast

Traders flag positive sentiment after U.S. chipmaker Marvell MRVL.O announced an aggressive growth forecast following $3.25 billion Celestial AI acquisition

Among single names, Dutch chip makers and suppliers ASML ASML.AS, ASM International ASMI.AS, BE Semiconductor rise around 3-4%

Their German counterparts Infineon IFXGn.DE, Siltronic WAFGn.DE and Aixtron AIXA.DE, ams Osram AMS2.VI gain 2-3.5%, while Franco-Italian STMicroelectronics STMPA.PA and Soitec SOIT.PA rise 3.2-4.7%

Separately, BofA says three key bear arguments on ASML are poised to turn positive:

• lithography intensity set to reach 26% by 2028 driven by EUV adoption,

• customer concentration risk easing as Samsung 005930.KS regains competitiveness,

• Micron MU.O and Intel INTC.O accelerate EUV adoption,

• China sales normalize to low-to-mid 20%

The stocks follow South Korea's main index KOSPI .KS11 closing 1% higher overnight, with Samsung 005930.KS rising over 1%

Europe's tech index .SX8P gains 1.56%
