* Emerging markets underperform global stocks
* Polish zloty rises after ratings comment
By Natsuko Waki
LONDON, Sept 16 (Reuters) - Emerging market stocks fell on Thursday after this week's rally brought the index to a 4-1/2 month peak, while the Polish zloty outperformed other currencies after positive comments from a ratings agency.
Central European stocks were slightly lower to steady <.MIEE00000PUS> <.TRXFLDEEPU> while broader emerging market stocks, measured by MSCI <.MSCIEF>, lost half a percent. The benchmark world equity index lost almost 0.2 percent.
"Sentiment has been quite good recently because macroeconomic numbers especially in emerging markets are starting to look better now again. Today it's mixed because people are taking a pause," said Flemming Nielsen, senior emerging market analyst at Danske Bank in Copenhagen.
The Polish zloty rose a quarter percent against the euro to 3.93 <EURPLN=> after ratings agency Moody's said there was upward pressure on ratings in Poland.
Moody's has an A2 rating for Poland with a stable outlook. Poland is battling rising debt and both Moody's and Fitch have said reforms were needed to safeguard the country's rating.
Poland was the only one in the EU that has not suffered a recession during the crisis, with deputy finance minister Ludwik Kotecki saying on Wednesday that third-quarter growth would come in at around 3.5 percent.
POLAND VS HUNGARY
Poland priced its 10-year euro-denominated bond issue worth 1 billion euros at 120-125 basis points above mid-swaps and investor demand for the 10-year paper topped 4 billion euros.
"It's at the right time, prices have been cheapening, and the country has this benign perception. it's the opposite of what we are seeing in Hungary," Elisabeth Gruie, strategist at BNP Paribas.
"We have a decoupling between these two countries. The zloty/forint should go higher."
The Hungarian forint fell a fifth of a percent to 282.40 per euro <EURHUF=>, a day after two leading ratings agencies warned of risks stemming from the country's fiscal deficit.
Moody's said on Wednesday it could downgrade Hungary's sovereign rating if the government fails to present a consistent plan to address fiscal issues.
Standard & Poor's said Hungary's commitment to the European Union's deficit requirements is insufficient to revise its negative ratings outlook.
Hungary plans to sell foreign currency-denominated bonds worth 4 billion euros and forint-denominated bonds worth 1.485 trillion forints in 2011.
"More solid medium term fiscal and economic policy anchors are needed. We struggle to see value in Hungarian government bonds at current levels, especially with the higher planned net issuance for 2011," Societe Generale said in a note to clients.
The Turkish lira fell around 0.3 percent to 1.4906 per dollar <TRY=> after data showed domestic consumer confidence eased again in August, extending a retreat from a June peak following seven months of improvement.
The central bank is expected to leave interest rates on hold at its monthly meeting later.
On Wednesday, S&P forecast Turkish economic growth in excess of 8 percent in 2010, noting the country's strong domestic demand-driven upturn was driving up the current account deficit.
S&P, which rates Turkey two notches below investment grade, reiterated that the "positive outlook" it held on Turkey signalled the likelihood of an upgrade in the next 12-24 months. (Additional reporting by Carolyn Cohn; editing by Chris Pizzey)
