* Fortis tumbles on funding fears

PARIS, Sept 25 (Reuters) - European stocks ended sharply higher on Thursday, rising for the first time in four sessions as renewed optimism over a U.S. bank rescue plan eclipsed weak economic data and a profit warning by General Electric <GE.N>.
The FTSEurofirst 300 <
> index of top European shares closed 2.2 percent higher at 1,125.46 points.U.S. lawmakers were getting close to an agreement on the $700 billion bailout plan on Thursday with more protections for taxpayers, fuelling hopes that a bipartisan consensus on the plan to rescue the embattled financial sector could be reached in time for a meeting at the White House later in the day.
Banking stocks were among the biggest gainers, with Credit Agricole <CAGR.PA> gaining 6.5 percent and Royal Bank of Scotland <RBS.L> adding 5 percent. UBS <UBSN.VX> soared 5.1 percent, also buoyed by speculation that HSBC <HSBA.L> could bid for the Swiss lender. Both UBS and HSBC declined to comment.
"The very low treasury yields, the huge spike in equity volatility and the current spreads... that is all indicating a very high level of risk aversion," said Arthur van Slooten, strategist at Societe Generale, pointing out it could be a sign that the bottom of the market has been reached.
"We still don't have the hard details about the rescue plan, but if they manage to get a package of this size in just two weeks, that would be an absolute record. Now it all depends on that going through before being able to call it the bottom of the market."
Bucking the trend in the financial sector, Fortis <FOR.BR><FOR.AS> ended 6.3 percent lower after losing as much as 20 percent in intraday trading, hit by persistent worries over its funding, several traders said. A spokeswoman for Fortis denied market talk the Dutch Central Bank had asked Rabobank [
] to support Fortis with liquidity.Insurers were also on the upside, with Munich Re <MUVGn.DE> gaining 4.4 percent, pushed higher by talk that U.S. investor Warren Buffett and Swedish investor Cevian were upping their stakes in the reinsurer.
"We never comment on market rumours. We always said that we welcome every interest in our shares," a Munich Re spokesman said.
BLEAK U.S. DATA
But Thursday's rebound was reined in by General Electric's profit warning as well as bleak U.S. macroeconomic data.
The U.S. industrial conglomerate slashed its earnings forecast, saying the crisis in global credit markets could drive its profit down as much as 12 percent.
"It's not that surprising. The economy is clearly slowing, so it's normal to see GE, heavily involved in the economy as a whole, warning on its outlook," said Philippe Gijsels, senior equity strategist at Fortis Bank, in Brussels.
"I fear that there will be more of the same in the industrial sector in a not too distant future."
Adding to worries over the health of the U.S. economy, data showed sales of newly constructed U.S. single-family homes in August fell to their lowest point in more than 17 years while prices hit four-year lows.
New orders for long-lasting manufactured goods dropped by a sharper-than-expected 4.5 percent in August as demand for transportation equipment and many other costly items sank.
The FTSEurofirst 300 is down 25 percent so far in 2008, hammered by fears over the impact of the crisis in the credit market that has forced banks to unveil massive asset writedowns and prompted Wall Street investment bank Lehman Brothers <LEHMQ.PK> to file for bankruptcy protection.
The benchmark index rallied strongly last week on news Washington was working on a plan to purge banks' balance sheets from bad mortgage-related debt.
Around Europe on Thursday, UK's FTSE 100 index <
> rose 2 percent, Germany's DAX index < > added 2 percent and France's CAC 40 < > gained 2.7 percent.Swedish truck maker Scania <SCVb.ST>, majority-controlled by Germany's Volkswagen <VOWG.DE>, surged 12 percent, on renewed bid rumours. Last year, the company fended off a bid by German rival MAN <MANg.DE>. Scania officials were not immediately available for comment. (Editing by Sue Thomas)
