LONDON, Sept 14 (Reuters) - A fall in economic sentiment in euro zone powerhouse Germany knocked eastern European stocks down half a percent on Tuesday after four days of gains while broader emerging stocks eased to trade just above flat.
The September ZEW survey of business sentiment fell to the lowest since March 2009, signalling that Germany's recent turbo-charged growth recovery may be flagging.
Stocks fell 0.5 percent by 1030 GMT in emerging Europe, which relies heavily on Germany for exports and investment. Czech <
> and Polish < > stocks fell half a percentBut regional markets <.MIEE00000PUS> <.TRXFLDEEPU> are still up 5 percent on the year and close to their highest since end-April. Broader MSCI emerging stocks <.MSCIEF> were flat but remain at 4-1/2 month highs and rose 2 percent on Monday, the biggest one-day gain in over a month.
The weak ZEW comes as a blow after recent data in the United States, China and other emerging economies as well as improved forecasts for euro zone growth, appeared to hint that the world economy may be in better shape than believed.
"We are in an up-and-down kind of environment and markets trading from one piece of data to the next," said Agata Urbanska, emerging markets strategist at ING in London. "It's really too early to be very optimistic about the U.S. recovery."
She said that while the latest ZEW survey had knocked central European assets, ING remains constructive on German growth and the outlook for much of central Europe.
"As long as exports continue to grow, there is still support for labour markets in the region," she added.
On currencies, the zloty and forint slipped a quarter percent to the euro <EURPLN=> <EURHUF=> with the latter failing to benefit from a T-bill auction which saw the Treasury place more paper than expected at a lower yield than last week's sale.
Romania's leu jumped 0.7 percent to the euro <EURRON=>. Five local dealers attributed the move to central bank action to prop up the leu which had weakened to two-month lows last week.
MORE GOOD NEWS IN TURKEY
There was good news in Turkey, one of this year's top emerging markets as forecast-beating data showed economic growth of 10.3 percent in the second-quarter. That helped markets hold gains made after a weekend referendum showed strong support for the ruling AKP party ahead of next year's elections.
The Istanbul index <
> inched to a new record high before easing while the lira slipped 0.4 percent to the dollar <TRY=> in line with weakness in other emerging currencies.Analysts attributed the subdued market reaction to crowded positioning as well as to expectations that interest rates will not be raised off record lows for some time to come.
"A good figure that supports the momentum in Turkish equities. The central bank must be happy with the recovery and we don't see any particular inflationary pressure for the time... We will obviously be raising our whole year forecast closer to the 7 percent year-on-year mark from 6.1 percent, with risk even to the upside," Chevreaux analysts said in a note.
The South African rand eased 0.4 percent but remained close to 2-1/2 month highs <ZAR=>. The currency has risen more than 3 percent this month despite last week's rate cut to 30-year lows as investors have piled into South African bonds.
On bond markets, Argentina outperformed following a ratings upgrade to B on Monday, its portion of JP Morgan's EMBI Plus and EMBI Global indices tightening 12 bps to U.S. Treasuries. Both indices showed flat spreads over Treasuries <11EMJ> <11EML>. Analysts say range trade is likely ahead of U.S. retail sales data. But many appear hopeful on the global recovery.
Indian stocks for instance <
