(Updates to explain RBS share move)
By Sitaraman Shankar
LONDON, May 19 (Reuters) - European stocks ticked up by midday on Monday as buoyant commodity stocks made up for losses in financials, while bearish brokerage comment punctured British Airways <BAY.L>.
At 1104 GMT, the FTSEurofirst 300 <
> index of top European shares was up 0.13 percent at 1,367.04 points, extending a three-day winning run. The index is up 2 percent so far this month, adding to a 6 percent rise in the index in April.Energy stocks featured prominently among the top weighted gainers, with Total <TOTF.PA> rising 0.9 percent, BG Group <BG.L> 2.1 percent and BP <BP.L> 0.5 percent, as crude traded at $126 a barrel.
Four miners were the top winners among British stocks -- Kazakhmys <KAZ.L>, Vedanta <VED.L>, Anglo American <AAL.L> and Lonmin <LMI.L> gained between 3.3 and 5.7 percent.
"I'm a big believer in the long-term commodity bull run, but we expect a correction at some point as they are very much overbought," Philippe Gijsels, strategist at Fortis in Brussels, said.
"We are neutral but not underweight on the sector as it would be really dangerous to stand in front of a train that's running this fast," he added.
RBS fell 4.3 percent to lead banks lower, with investors citing a technical sell-off related to its rights issues and gloom in the banking sector. Goldman cut its price target on the stock to reflect it going ex-rights.
Other banks were also weaker, with Alliance & Leicester <ALLL.L> falling 2.7 percent, HBOS 2.8 percent and Societe Generale <SOGN.PA> down 1.2 percent.
British mid-cap Bradford & Bingley <BB.L> slid nearly 9 percent on worries over its outlook and a 300 million pound cash call, with some analysts already valuing the firm as if it was no longer writing new business.
Banking stocks have been hit over the past year by fears over the impact of a meltdown in the risky U.S. subprime mortgage market that has forced many banks to unveil massive asset writedowns and emergency capital increases.
The DJ Stoxx banking index <.SX7P>, one of the worst performing sectors in Europe so far this year, has lost 15 percent year to date.
German online mortgage financier Interhyp <IYPGn.DE> surged 37 percent after a unit of Dutch financial services group ING <ING.AS> offered 416 million euros for it.
British Airways <BAY.L> fell 5.3 percent after downgrades to "sell" from ABN AMRO and Deutsche Bank.
BEAR MARKET RALLY
The FTSEurofirst has gained 14 percent since mid-March, when the Federal Reserve helped bail out stricken U.S. bank Bear Stearns <BSC.N>, but is still down 16 percent from a 6-1/2 year peak hit last July.
While a credit market crisis sparked by the collapse in U.S. subprime mortgages has caused a stock bull run to come to a screeching halt, things have looked up for equities in the past couple of months due to U.S. rate cuts and reasonable results from Europe's biggest companies.
But analysts categorise the recovery as a bear-market rally that is sensitive to any bit of negative data.
"Bear market rallies since 1973 last for an average of 35 trading sessions and add 11-12 percent to markets," said Gijsels, pointing out the S&P 500 <.SPX> was around this level now.
"There's a danger that economic figures will disappoint over the next couple of quarters, while corporate figures will also deteriorate," he said.
Among other major movers, German truckmaker MAN AG <MANG.DE> rose 3.5 percent after Goldman Sachs raised its price target on the stock.
Fertiliser maker K+S <SDFG.DE>, which has outperformed the broader market so much in recent months on the back of higher potash prices that it is now a strong candidate to join Frankfurt's blue-chip DAX index <
>, gained 3.4 percent after positive analyst notes from two banks.Around Europe, Germany's DAX index <
> was up 0.4 percent, UK's FTSE 100 index < > up 0.2 percent and France's CAC 40 < > up 0.3 percent. (Editing by Sue Thomas)
