LONDON, April 1 (Reuters) - Britain's top shares gained 0.7 percent by midday on Thursday, as miners and energy stocks, backed by higher commodity prices, and risk sensitive banks led a broad-based rally ahead of the Easter break.
By 1045 GMT the FTSE 100 <
> was up 40.30 points at 5,719.94 after ending up 7.32 points, or 0.1 percent, on Wednesday, the final session of the first quarter.Trade was light approaching midday, with the blue-chip index having traded around 25 percent of its average 90-day volume.
"We've seen some gentle but fairly broad-based strength this morning, with the resources sector leading the market higher on the first day of the second quarter," said Anthony Grech, market strategist at IG Index.
Miners delivered the bulk of the gains with the sector buoyed by firmer metal prices, which spiked after two surveys showed a climb in orders from China's vast manufacturing sector, pointing to brisk first-quarter GDP growth. [
]Rio Tinto <RIO.L>, Xstrata <XTA.L>, Lonmin <LMI.L>, Anglo American <AAL.L>, Kazakhmys <KAZ.L> and BHP Billiton <BLT.L> added 1.9 to 3.6 percent.
"With trading volumes likely to wind down in the run-up to the Easter break, we may see the market amble, rather than sprint, towards the finish line this afternoon," said Grech, who pointed out that investors will be eyeing the U.S. Challenger job-cut report later in the session, ahead of the non-farm payrolls on Friday.
Analysts forecast a 190,000 increase in U.S. jobs in March after a fall of 36,000 in February, but investors will have to wait until Tuesday to see equity market reaction as equity markets are closed on Friday and Monday.
The FTSE 100 gained 6.1 percent in March, its strongest month since last August, and is up 4.9 percent this year after gaining 22 percent in 2009. It has gained in four consecutive quarters after seeing five quarters of losses prior to that.
RISK RETURNS
As investor confidence grew over the outlook for the global economy, so did their appetite for perceived riskier assets, with energy and banking stocks supporting gains in the FTSE 100.
BG Group <BG.L>, BP <BP.L>, Tullow Oil <TLW.L> and Cairn Energy <CNE.L> added 0.4 to 3.3 percent, with crude heading above $84 per barrel <CLc1>.
Banks Barclays <BARC.L>, HSBC <HSBA.L>, Standard Chartered <STAN.L>, Royal Bank of Scotland <RBS.L> and Lloyds Banking Group <LLOY.L> all gained between 0.5 and 2.2 percent.
Adding to the optimism, British banks expect to strongly increase corporate lending and unsecured lending to households over the next three months, a Bank of England survey showed. [
]British manufacturing activity grew last month at its fastest rate since October 1994, when the economy was also recovering from a deep recession, a survey of purchasing managers showed. [
]On the downside, mobile phone heavyweight Vodafone <VOD.L> shed some recent gains and was the biggest drag on the index, down 1.5 percent after regulator Ofcom proposed cutting the cost operators can charge each other to connect calls on their network. [
