Tech stocks slump 3.6% to a near three-month low EU banks only sector to rise Euro zone investor morale inches up Atos plunges on profit warning Jan 10 (Reuters) - European shares posted their biggest one-day drop since late November on Monday as rising bond yields weighed on the heavyweight technology sector, while the rapid spread of the Omicron COVID-19 variant also dented sentiment. The pan-European STOXX 600 (.STOXX) closed 1.5% lower, with technology stocks (.SX8P) tumbling 3.6% to a near three-month low. Losses were spread out across most European sectors. Rising bond yields in Europe and the United States were the main driver behind the stock rout, as investors awaited an end to pandemic-era liquidity measures in the wake of surging inflation. "Inflation is concentrating minds of investors in Europe... which is piling the pressure on the ECB (European Central Bank) to tighten monetary policy," said Susannah Streeter, senior investment and markets analyst at Hargreaves Lansdown. December inflation rose to a record high of 5% for the currency bloc, data showed last week. read more On Monday U.S. 10-year yields hit a two-year high, while Germany"s 10-year yields briefly hit their highest since May 2019.

Credit Suisse (CSGN.S) rose 1.3% after traders cited media speculation about a possible sale or merger of the embattled Swiss bank.

But a survey showed on Monday that investor morale in the euro zone had risen this month as momentum is not expected to slow despite the new variant.
