March 5 (Reuters) - London's FTSE 100 index fell for the
first time this week on Thursday, led by a slate of companies
trading ex-dividend, with sentiment again dampened by concerns
over global economic growth in the wake of the coronavirus
epidemic.
The blue-chip index and the mid-cap index
were both down 1%.
Asia-focussed bank Standard Chartered, housebuilder
Persimmon, and miners BHP Group and Rio Tinto
, which were all trading without dividend entitlement,
dropped between 4.3% and 5.1%.
Britain's stock markets have rebounded since Monday
following their worst week since the 2008 financial crisis, as
early evidence of the economic hit from the outbreak spurred
hopes of monetary stimulus from central banks.
Signs of economic damage continues to pile up, however, with
British regional airline Flybe a high profile casualty on
Thursday as it shut operations just a month after a
publicly-sanctioned rescue.
"There is a certain amount of fear and nervousness in the
market," said Keith Temperton, a trader at Tavira Securities.
A surprise interest rate cut by the U.S. Federal Reserve on
Tuesday pumped yet more money into financial institutions but it
also added to a growing sense of panic among investors coddled
by a decade of constant stock market gains.
The IMF now predicts that global GDP could see its slowest
growth since 2008-2009 this year and Deutsche Bank analysts on
Thursday cut their forecast for British economic growth in 2020
to just 0.5%.
Deutsche's economists outlined a range of expected official
responses to the outbreak, including two cuts in interest rates
by the Bank of England by May.
The market's chief fear index was up 9% at 34.91 on
Thursday.
"Markets might want to push for another Fed rate cut,"
Tavira's Temperton said. "The European Central Bank, on the
other hand, doesn't have a lot of room. Once volatility markets
are trading in the mid-30's, things become very speculative."
Miners, airlines and luxury goods
makers were hit hard last week as the virus spread
deeper in Europe and the United States and crippled supply
chains and travel demand.
Shares in British Airways-owner IAG fell 1.9%,
while EasyJet was flat. The mining index declined 4.2%,
also pressured by a strong pound.
Broadcaster ITV slumped 8.6% and was on course for
its worst day in over three years after it warned of lower ad
revenue in April. UK outsourcer Capita Plc sank as much
as 15% on signs its restructuring drive would require more
capital.
