Feb 15 (Reuters) - British stocks rose on Monday, as mining
and energy stocks tracked strong gains in commodity prices and
investors were hopeful global vaccine rollouts would quicken the
economic recovery this year.
The commodity-heavy FTSE 100 .FTSE was up 2.5%, clocking
its best day in over a month, boosted by miners Anglo American
AAL.L , Rio Tinto RIO.L and BHP Group BHPB.L and oil
producers BP BP.L and Royal Dutch Shell RDSa.L .
"Government attempts to manage expectations on COVID-19
better are helpful to the market which is now probably
pleasantly surprised at just how quickly the UK has vaccinated
the most vulnerable sections of its population," said Russ
Mould, investment director at AJ Bell.
"This is making it easier for investors to look through to a
reopening of the economy even if the pace at which restrictions
are eased remains a topic of fierce debate."
The FTSE 100 has recovered nearly 34% from its March 2020
lows, led by a raft of stimulus measures, but a surge in
infections and recent widespread lockdowns have slowed economic
growth. The index has also lagged its U.S. and European peers.
England's new COVID-19 hotel quarantine system for arrivals
from high-risk countries is running smoothly after it was
introduced earlier in the day, the health minister said.
British Prime Minister Boris Johnson said he would plot a
"cautious but irreversible" path out of the COVID-19 lockdown,
after the vaccination of 15 million people so far in Britain.
The mid-cap FTSE 250 index .FTMC added 1.8%, reaching over
11 month high, with travel group TUI AG TUIT.L gaining the
most.The wider travel and leisure sub-index .FTNMX5750 gained
4.3%.
Britain's housebuilding sector .FTNMX3720 gained 2.1% as a
survey showed asking prices for homes unexpectedly rose in
January and early February. In company news, Rolls-Royce RR.L rose 3.5% after
appointing Panos Kakoullis, the former head of Deloitte's audit
and assurance practice, as its new chief financial officer.
Pub operator Mitchells & Butlers MAB.L jumped 7.9%, after
plans to raise 350 million pounds ($486.05 million) through an
open offer of shares.
