LONDON, May 15 (Reuters) - Britain's top shares index rose by midday on Thursday, as results boosted BT <BT.L> and Cadbury <CBRY.L>, but banks capped gains after Barclays <BARC.L> refused to rule out a rights issue after posting a $2 billion writedown.
BT contributed most points to the index, gaining 3.7 percent after the telecoms operator posted a rise in fourth-quarter underlying core earnings, in line with forecasts, and said it expected to deliver continued growth next year. [
]Cadbury rose 5 percent after the confectionery company said it expected strong first-half performance. The stock also benefited from upbeat broker notes from Numis and Panmure.
By 1109 GMT, the FTSE 100 <
> reversed earlier losses to rise 10.6 points, or 0.2 percent, to 6,226.6 as the broader European stock market traded flat.Leading the losers' list, Barclays <BARC.L> shed 3.4 percent after saying profits fell in the first quarter after it took a 1 billion pound writedown on assets tarnished by the credit crunch, but it did not disclose the extent of its profit fall.
The bank also refused to rule out a rights issue. [
] [ ]HBOS <HBOS.L>, Lloyds TSB <LLOY.L> and Alliance & Leicester <ALLL.L> lost between 1.2 and 2 percent. Royal Bank of Scotland <RBS.L>, trading ex-rights, edged up.
"(The sector's) going to be a bit of a burden for the market for some while. We have to resign ourselves to the fact that that's one sector that we can't expect very much from," Mike Lenhoff, chief strategist at Brewin Dolphin, said.
"We probably aren't going to go anywhere in the very short term," he added. "The market is probably set to trade around this level for a little while."
Elsewhere, Wall Street looked set to rise at the start on Thursday with the focus on earnings from key retailers JC Penney <JCP.N> and Nordstrom <JWN.N> along with tech company Hewlett-Packard <HPQ.N>.
MINERS DRAG
Miners were also standout losers after recent gains and after Indian-focused Vedanta Resources <VED.L> posted a 7.1 percent fall in annual underlying earnings per share despite stronger output, reflecting a share issue and higher minority interests. [
]Vedanta dipped 1 percent, while BHP Billiton <BLT.L>, Rio Tinto <RIO.L> and Antofagasta <ANTO.L> all shed between 0.7 and 1.6 percent. Some stocks in the sector have been trading at record levels this week.
Xstrata <XTA.L> lost 0.9 percent. The miner bid nearly $400 million for Australia's Indophil Resources <IRN.AX>, which rejected the offer and said it did not reflect the value of the company. [
]Oil stocks capped some of the index's losses, however, with BP <BP.L> up 0.7 percent and its rival Royal Dutch Shell <RDSa.L> rising 0.9 percent as U.S. crude oil prices recovered towards $125 a barrel.
Brewer SABMiller <SAB.L> advanced 4.4 percent. The company reported a 19 percent rise in annual earnings but said beer volume growth in its current first-half would be affected by high input costs and comparative figures. [
]ITV <ITV.L> shed 3 percent after the broadcaster said its turnaround plan was on track as it had outperformed the television advertising market and increased audience share. [
]Among mid-caps, DSG International <DSGI.L>, Europe's largest specialist retailer, dropped 9.4 percent after announcing it would slash its dividend and shut stores in an effort to turn around the business. (Additional reporting by Dominic Lau; editing by Sue Thomas)
