LONDON, Oct 29 (Reuters) - World stocks fell on Friday and the dollar slid towards its 1995 record low versus the yen as investors braced for U.S. growth data to assess the likely scale of fresh Federal Reserve monetary easing.
Third-quarter growth data for the world's biggest economy due out on Friday will be a key factor for the Fed, which is expected to decide next week on the scale of its bond buying as part of a quantitative easing programme.
In the past week investors have become nervous that the Fed may disappoint the markets with the scale of fresh easing. Most leading economists expect the Fed to say it will buy $80 billion to $100 billion worth of assets per month. [
]"There is uncertainty ahead of the Fed statement for sure," said Bernard McAlinden, investment strategist at NCB Stockbrokers in Dublin.
"There's a feeling the market maybe has over-priced in QE. You've had half-decent data in the United States. I think the Fed will announce QE. It's a question of how much and the nature of what they do." MSCI world equity index <.MIWD00000PUS> fell 0.4 percent. moving away from a two-year high set earlier this week. The index is still up 5 percent since January.

Data from fund tracker EPFR shows flows into emerging market funds slowed significantly in the fourth week of October as investors awaited the Fed outcome.
The emerging market equity and bond funds tracked by EPFR took in a combined $3.4 billion, slowing from the $5.8 billion they took in the previous week. [

Bund futures <FGBLc1> rose 33 ticks.
GUESSING GAME
The dollar fell as low as 80.54 yen <JPY=>, within a yen of a record low of 79.75 set in 1995.
The dollar <.DXY> rose 0.5 percent against a basket of major currencies. The dollar has shed about 7 percent in the past two months, and some analysts say it is due for a rally once the Fed reveals its easing plans.
Market expectations have centred on an initial commitment to buy at least $500 billion in Treasury debt over five months to spur lending and support an economic recovery that is too weak to tame high unemployment.
Further muddying the outlook, Fed officials have offered conflicting signals on their policy predilections in recent weeks, with some pushing for very aggressive stimulus and others highly sceptical of any additional accommodation.
"The second-guessing continues, with some suggesting the Fed will try to avoid a major disappointment and thus will deliver whatever the market is looking for," BNP Paribas said in a note to clients.
"We concur, favouring a slow-release $500 billion over six months, albeit perhaps with an open-ended promise of more to come if warranted. This should be dollar-supportive." (Editing by Hugh Lawson)
