Jan 21 (Reuters) - London's FTSE 100 slipped on Thursday,
weighed down by falls in energy stocks as oil prices slid after
a surprise increase in U.S. crude inventories, while IG Group
tumbled on plans to buy U.S. trading platform tastytrade for $1
billion.
The blue-chip FTSE 100 index .FTSE lost 0.4%, while the
domestically focussed mid-cap FTSE 250 index .FTMC also slid
0.4%.
Energy majors BP BP.L and Royal Dutch Shell RDSa.L fell
3.2% and 2.5%, respectively, and were the biggest drags on the
FTSE-100 index. O/R
"What is holding back the UK is a lack of tech stocks to
capture the 'rotation' back into tech seen since Netflix
results," said Chris Beauchamp, chief market analyst at IG.
"Stock markets overall are much quieter today, looking so
far in vain for a new catalyst for further upside."
The FTSE 100 shed 14.3% in value last year, its worst
performance since a 31% plunge in 2008 and underperforming its
European peers by a wide margin, as pandemic-driven lockdowns
battered the economy and led to mass layoffs.
British Prime Minister Boris Johnson said it was too early
to say when the national coronavirus lockdown in England would
end, as daily deaths from COVID-19 reach new highs and hospitals
become increasingly stretched. IG Group IGG.L tumbled 8.5% after announcing plans to buy
tastytrade, venturing into North America after a stellar year
for the new breed of retail investment brokerages. Ibstock IBST.L jumped 7.3% to the top of the FTSE 250
after the company said fourth-quarter activity benefited from
better-than-expected demand for new houses and repairs.
Pets at Home Group Plc PETSP.L rose 2.2% after reporting
an 18% jump in third-quarter revenue, boosted by higher demand
for its accessories and veterinary services as more people
adopted pets during lockdowns.
