March 26 (Reuters) - A strong bounce on Wall Street helped Britain's stock markets recover from early losses on Thursday, as shocking economic data from across the world due to the coronavirus pandemic fed into expectations of more stimulus actions.
After falling as much as 3% during the midday, the blue-chip FTSE 100 closed 2.2% higher, recording its first three-day gain since the coronavirus crisis started hitting equity markets in February. Midcap stocks rose 3.8%, gaining for the fifth straight session.
Data showed a staggering 3.3 million people filed for U.S. unemployment benefits last week as lockdown brought economic activity to a sudden halt, while British retail sales stagnated in February, even before shops shuttered.
The rest of Europe also saw weak numbers, hit by the pandemic.
However, Wall Street rallied more than 4% as investors hoped for further aid from the U.S. government, including a $2.2 trillion coronavirus relief bill that lawmakers are expected to pass on Friday.
"With the U.S. markets in high spirits, Europe was able to edge into the green," said Connor Campbell, financial analyst at SpreadEx in London.
The Bank of England said on Thursday it was ready to ramp up its bond-buying programme further if needed. Separately, finance minister Rishi Sunak said that self-employed people will receive a taxable grant of 80% of their average monthly profits as part of coronavirus support package.
However, analysts are skeptical about the strength of the stock markets' recovery, with the main FTSE 100 still down about 25% from its January peak.
"Investors should plan for headlines describing large declines in GDP, stark rises in unemployment, and waning confidence numbers," Peter Essele, head of portfolio management for Commonwealth Financial Network, wrote in a client note.
"It's quite possible that this week will be seen as the calm before the storm."
