Nov 25 (Reuters) - Britain's FTSE 100 rose on Monday on
renewed hopes an initial Sino-U.S. trade deal may be clinched
this year while further signs the Conservatives are set to win
an election next month drove mid-caps to their highest since
September 2018.
The main index .FTSE climbed 1%, boosted by miners
.FTNMX1770 and Asia-focused financial stocks HSBC HSBA.L and
Prudential PRU.L after the U.S. national security adviser said
a preliminary trade deal was possible this year. The index, which jumped more than 1% in the previous
session, was also supported by a 3% gain in Burberry BRBY.L
after rival LVMH LVMH.PA agreed to buy U.S. jeweller Tiffany
TIF.N for $16.2 billion. The more domestically-focussed FTSE 250 .FTMC rose 1.1%,
in tandem with sterling after opinion polls showed the
Conservatives were still favourites to win the Dec. 12 election,
raising the likelihood of Brexit happening. The mid-cap index has gained 2.5% since Oct. 29, when
parliament approved Prime Minister Boris Johnson's call for an
election, and hit its highest since Sept. 4, 2018.
Blue-chip housebuilders such as Berkeley BKGH.L , Barratt
BDEV.L and Persimmon PSN.L climbed about 1.5% each while
UK-exposed banks such as Lloyds LLOY.L , Barclays BARC.L and
RBS RBS.L advanced nearly 2%.
JP Morgan's basket of London-listed firms .JPDEUKDM that
make their cash at home rallied 1.4% to its highest since April.
However, shares of Restaurant Group RTN.L slumped nearly
9% after the owner of Frankie & Benny's reported slowing
like-for-like sales growth at its Wagamama business in Britain.
Hochschild Mining HOCM.L , which fell 9% on Friday after a
lacklustre production outlook for 2020, also underperformed,
losing another 7% and hitting its lowest in almost six
months. Despite a firmer pound, the exporter-heavy FTSE posted gains
as Sino-U.S. trade sentiment was boosted by China's assurance of
stronger protections for intellectual property, which analysts
have identified as a key factor in trade talks. "The move suggests that key concessions are being made in
order to increase the prospects of a partial U.S.-China deal,
which is giving investors another opportunity to capitalise on
risk-on trading activity," FXTM analyst Han Tan said.
IAG ICAG.L rose 2% after British Airways and its pilots
union BALPA reached a preliminary agreement to end the pay
dispute that resulted in the first walkout by pilots in the
airline's history.
