By Francesco Canepa LONDON, Dec 13 (Reuters) - European stocks are seen opening flat to higher on Thursday as investors balanced a new monetary boost from the U.S. Federal Reserve with lingering concerns that austerity measures could derail the world's largest economy. At 07 23 GMT, futures for the Euro STOXX 50 were up 0.2 percent , contracts on Germany's DAX were flat and futures for France's CAC were up 0.1 percent. The Fed announced a new round of monetary stimulus on Wednesday and indicated interest rates would remain near zero until unemployment falls to 6.5 percent, but chairman Ben Bernanke warned that monetary policy won't be enough to offset damage from a "fiscal cliff" of steep tax hikes and budget cuts scheduled to kick in on Jan. 1. Congressional Republicans and the White House are in talks to avert the 'fiscal cliff' but negotiators warned on Wednesday the showdown could drag on past Christmas as sharp differences remained. The Fed's new stimulus plan had briefly pushed the U.S. S&P 500 to a seven-week high on Wednesday before Bernanke's comments on the 'cliff' dampened investor optimism, sending the index to a flat close. "While these measures clearly show that the Fed is doing everything in their power to give the economy a major boost it still remains questionable just how much if at all these bond really help and if instead they merely raise the prospects of inflation in the future," Markus Huber, a senior trader at ETX Capital, said. "Now with the Fed out of the way, focus will now increasingly shift towards the 'fiscal cliff' with time starting to run out and some major progressed will have to be made soon otherwise markets might just start pricing in the US going over the cliff." Copper and crude prices, which depend on economic activity, fell early on Thursday and concerns about U.S. economic growth was expected to cap gains on European equity indexes after a steep three-week rally. Charts showed the FTSE 100, DAX, CAC 40 and the euro zone's blue chip Euro STOXX 50 heading into 'overbought' territory, with their relative strength index (RSI), a closely-watched momentum indicator, above 70, which could trigger a pause in the recent rally. The Euro STOXX 50 index hit a 16-month high on Wednesday and is up 30 percent since June as asset purchase plans by global central banks drove down bond yields and led investors to chase superior returns among equities. Sentiment surrounding the euro zone, in particular, had improved on the back of a September pledge by the European Central Banks to buy the debt of countries that apply for international aid, driving implied volatility on the region's blue chips, as measured by VSTOXX index to lows not seen in five years. The euro zone made further steps towards closer integration on Thursday as it clinched a deal to give the ECB new powers to supervise banks from 2014. But the region's recession was estimated to have deepened in the last three months and the chances of a recovery faded further into 2013, according to a Reuters poll, clouding the prospects for corporate earnings and making its more difficult for governments to reduce their deficits. Companies in the pan-European STOXX 600 index were expected to report a 9 percent increase in earnings next year, Thomson Reuters StarMine data showed, an estimate that many strategists saw as overly rosy. The index traded at 11.3 times its expected earnings for the next twelve months, its highest valuation multiple since 2010, according to Datastream figures, capping the appeal of European shares. "Earnings expectations are still too high and we do not see much room for higher valuations," Joost van Leenders, asset allocation specialist at BNP Paribas Investment Partners, said. "We do not think that the fiscal crisis in the eurozone is fully under control, so (that) may weigh on markets at some point." He expected European stock indexes to fall between 5 and 10 percent by mid-2013 and rebound in the second half, thanks to a stabilisation in the economy, to end the year between flat and 5 percent down. -------------------------------------------------------------------------------- MARKET SNAPSHOT AT 729 GMT LAST PCT NET CHG CHG S&P 500 1,428 0.04 % 0.64 48 NIKKEI 9,742 1.68 % 161.2 73 MSCI ASIA <.MIASJ0 0.35 % 1.88 EX-JP 00PUS> EUR/USD 1.309 0.14 % 0.001 USD/JPY 83.61 0.43 % 0.360 10-YR US <US10YT= 1.711 -- 0.01 TSY YLD R> 10-YR <EU10YT= 1.357 -- 0.02 BUND YLD R> SPOT GOLD $1,69 -0.81 -$13. .71 % 4 US CRUDE $86.5 -0.25 -0.22 % > Asian shares rise, yen falls after Fed's stimulus steps > Wall St ends almost flat as Bernanke warns on "cliff" > Nikkei touches 8-month high above 9,700, exporters rise > Treasuries drop as Fed unveils new bond-buying program > Dollar broadly weak after Fed, yen also retreats > Gold falls as Fed move raises concern on stimulus scope > LME copper falls after Fed; fiscal cliff worries drag > Crude slips as U.S. stocks rise, fiscal concerns weigh COMPANY NEWS: VOLVO French carmaker Renault said late on Wednesday it would sell its 6.5 percent stake in the world's second biggest truckmaker.
