* Adds further detail, analyst comment, company news items PARIS, May 22 (Reuters) - European stocks are seen mixed on Wednesday, with the market's month-long rally taking a breather as investors await clues from U.S. Federal Reserve Chairman Ben Bernanke on the central bank's stimulus measures before increasing their exposure to equities. At 0619 GMT, futures for Euro STOXX 50 were up 0.11 percent, for UK's FTSE 100 up 0.18 percent, for Germany's DAX up 0.08 percent and for France's CAC down 0.1 percent. European shares stalled around multi-year peaks on Tuesday, held back by worries over the outlook for the Fed's bond buyback programme following recent comments from Fed members. After the European close on Tuesday, however, two senior Fed officials played down the chances the central bank will soon signal a readiness to trim its bond buying programme, sparking gains on Wall Street. New York Federal Reserve Bank President William Dudley and St. Louis Fed chief James Bullard, both of whom will vote at the Fed's June 18-19 policy meeting, made clear further economic progress was needed before they would support curtailing bond purchases. "While Dudley's dovish comments weren't that much of a surprise, Bullard's overly dovish tone was, and his robust defence of the merits of QE was taken as a sign that maybe markets are expecting far too much from this afternoon's Fed minutes, as well as Bernanke's testimony to Congress," Michael Hewson, senior market analyst at CMC Markets, wrote in a note. Minutes from the Federal Open Market Committee's April 30-May 1 policy meeting will be released at 1800 GMT. The euro zone's blue chip Euro STOXX 50 index has surged 11 percent since mid-April, reaching a near-two year high, lifted mostly by massive central bank liquidity. In Japan on Wednesday, the country's central bank kept policy steady and upgraded its assessment of the economy, saying it "has started picking up," as Prime Minister Shinzo Abe's programme of aggressive fiscal and monetary stimulus has boosted sentiment while a weaker yen has halted a decline in exports. The sharp month-long rally has propelled the Euro STOXX 50's valuation ratio to levels not seen since early 2010, with the benchmark trading at 11.4 times expected earnings in the next 12 months, above a 10-year average price-to-earnings ratio of 11, data from Thomson Reuters Datastream shows. -------------------------------------------------------------------------------- MARKET SNAPSHOT AT 0620 GMT: LAST PCT CHG NET CHG S&P 500 1,669.16 0.17 % 2.87 NIKKEI 15,627.26 1.6 % 246.24 MSCI ASIA EX-JP 561.71 -0.08 % -0.47 EUR/USD 1.2911 0.05 % 0.0006 USD/JPY 102.57 0.11 % 0.1100 10-YR US TSY YLD 1.933 -- 0.00 10-YR BUND YLD 1.388 -- -0.01 SPOT GOLD $1,377.90 0.18 % $2.46 US CRUDE $95.77 -0.43 % -0.41 > GLOBAL MARKETS-Asian stocks cheered by Fed reassurance > Dow, S&P end at records on Fed officials' reassurance > Nikkei climbs 1.6 pct to 5-1/2-yr high on BOJ optimism, Sony surges > TREASURIES-Bonds supported after dovish Fed comments > Dollar treads water as investors hold breath for Bernanke testimony > PRECIOUS-Gold gains on China demand, hopes of US stimulus continuing > METALS-LME copper near 2-week top on hints Fed stimulus will stay > Brent dips further below $104 on nerves over summer demand COMPANY NEWS: PSA PEUGEOT CITROEN PSA Peugeot Citroen plans to close a research and administrative site near Paris and transfer its 660 workers to other plants as part of the French carmaker's cost-cutting plans, according to an internal document seen by Reuters.
