LONDON, Oct 30 (Reuters) - Britain's top share index rose for a third day in a row on Thursday as gains in banks and miners offset weakness in Royal Dutch Shell (RDSa.L), Stagecoach (SGC.L) and British American Tobacco (BATS.L) after their results.

The FTSE 100 .FTSE closed 49.11 points or 1.2 percent higher at 4,291.65 in a choppy session, swinging from a low of 4,200.24 to a high of 4,352.47. The UK benchmark rallied 8 percent on Wednesday, but it is still down 12.5 percent for the month and 33 percent for the year.

More than 1.3 billion shares changed hands, compared with 1.67 billion on Wednesday and last week's average of 1.49 billion.

"Things were very, very oversold last week. This week a lot of the doom and gloom has almost been factored in and people have suddenly thought that at these levels if I am taking a five-year view, it can't go that wrong," said Angus Campbell, head of sales at Capital Spreads.

"Whether it will be maintained is another question. It doesn't mean that sentiment has completely changed."

Banks benefited from the U.S. Federal Reserve's move to cut interest rates by half a percentage point to 1.0 percent on Wednesday to cushion the impact of a global recession.

The U.S. economy shrank at a 0.3 percent annual rate in the third quarter, its sharpest contraction in seven years as consumer cut spending and businesses reduced investment in the face of rising fears that recession was setting in. [ID:nN30534111]

Barclays (BARC.L), Royal Bank of Scotland (RBS.L), HSBC (HSBA.L), HBOS HBOS.L, Lloyds TSB (LLOY.L) and Standard Chartered (STAN.L) put on between 4 and 10 percent.

The sector was also supported after Deutsche Bank (DBKGn.DE) posted results that were not as poor as the market had expected. Deutsche Bank shares gained nearly 18 percent.

China, Norway, Taiwan and Hong Kong also cut interest rates, paving the way for the Bank of England and the European Central Bank to ease policy at their regular meetings next week.

Miners held on to their earlier gains, despite metal prices turning negative in afternoon trade. Vedanta Resources (VED.L) soared 15.8 percent, Xstrata (XTA.L) advanced 8.2 percent, BHP Billiton (BLT.L) added 5 percent, Rio Tinto (RIO.L) put on 3.3 percent and Antofagasta (ANTO.L) climbed 8.8 percent.
