The pan-European STOXX 600 index slipped 0.01% by 0707 GMT, with gains in oil & gas stocks offsetting losses in financial services firms. UK’s FTSE 100 rose slightly as oil major BP jumped 2.6% after its first-quarter profit soared due to stronger oil prices and bumper revenue from natural gas trading. Asia-focused lender HSBC gained 0.9% after it reported an upbeat quarterly profit as successful vaccine rollouts in key markets promised a brighter economic outlook. However, UBS fell 3.5% as it took an unexpected $774 million hit from Archegos, taking the shine off a forecast-beating 14% rise in quarterly net profit. Danish freight forwarder DSV Panalpina jumped 7.7% to the top of STOXX 600 after it agreed to buy the logistics division of Kuwait’s Agility Public Warehousing Co in a deal worth $4.1 billion.
