* Yen falls on indications G20 won't target Japan's policies * Wall Street resilient despite drag of Apple, Wal-Mart shares * Oil trims some losses to settle at $117.66 a barrel * Treasury prices also trim decline By Herbert Lash NEW YORK, Feb 15 (Reuters) - The yen fell against the euro and dollar on Friday amid expectations Group of 20 finance leaders this weekend will avoid targeting Japan over policies that have weakened its currency, while oil prices sank on signs of lagging economic activity. Wall Street closed flat, pressured by shares of Apple Inc and Wal-Mart Stores Inc, but the strength of a stock rally that has seen the benchmark S&P 500 index gain 6.6 percent so far this year kept markets from tumbling. The day's data underscored the still-bumpy road to economic recovery. The New York Federal Reserve reported manufacturing in New York state expanded while a survey showed a surprisingly strong rise in U.S. consumer sentiment in February. On the downside, U.S. industrial production unexpectedly dipped in January, spurring concerns about economic activity. Oil prices sank, with Brent futures finishing their first weekly loss since mid-January. The yen tumbled on a draft communique prepared for G20 finance leaders at their meeting that begins later on Friday in Moscow. The draft omits part of this week's Group of Seven statement declaring fiscal and monetary policy may only be used for domestic economic aims, a G20 delegate said. "The yen has reversed early gains and is now the weakest major currency on reports the language of the G20 statement may differ from that of the G7 countries," said Nick Bennenbroek, head of currency strategy at Wells Fargo in New York. "The G20 is expected to urge members to avoid competitive devaluation, but not echo the G7 view that exchange rates should not be a target of policy," he said. The United States is acting in line with the position of the G7 nations by using domestic policy tools to boost growth and reduce unemployment, Federal Reserve Chairman Ben Bernanke said. The euro last traded up 0.77 percent at 125.04 yen, after earlier falling to 122.87 yen, its lowest since Jan. 30. It hit a 34-month high of around 127.71 last week. The yen rallied earlier this week on expectations officials would express disapproval of Japan's policy. On Wall Street, the market hurt by a drop in Wal-Mart shares late in the session on a Bloomberg report quoting a mid-level executive's e-mail that said the world's largest retailer had the worst sales start to a month in seven years in February. Wal-Mart closed down 2.1 percent at 69.30, while Apple fell 1.38 percent to 460.17, the two biggest drags on the S&P 500. The Dow Jones industrial average closed up 8.37 points, or 0.06 percent, at 13,981.76. The Standard & Poor's 500 Index was down 1.59 points, or 0.10 percent, at 1,519.79. The Nasdaq Composite Index was down 6.63 points, or 0.21 percent, at 3,192.03. For the week, the S&P 500 rose 0.1 percent, while the Dow and the Nasdaq fell 0.1 percent each. A rise in U.S. consumer sentiment, according to The Thomson Reuters/University of Michigan index, initially drove gains in U.S. and European markets, before they reversed. The preliminary reading on the overall index of consumer sentiment rose to 76.3 from 73.8 in January, topping economists' forecasts of 74.8. A measure of global equity activity, MSCI's all-country world index, traded down 0.26 percent at 355.40. In Europe the FTSEurofirst 300 closed down 0.2 percent at 1,161.39, levels seen at the start of January. A surge in merger and acquisition activity, with more than $158 billion in deals announced in the first 45 days of the year, had supported the equity market as it indicates healthy valuations and a bright economic outlook. "You don't go into M&A if you don't have a positive outlook," said Art Hogan, managing director of Lazard Capital Markets in New York. In commodities markets, Brent futures for April delivery fell 34 cents to settle at $117.66 a barrel. U.S. crude shed $1.45 to settle at $95.86 a barrel. For the week, it eked out a gain of 14 cents. Industrial production slipped 0.1 percent after a revised 0.4 percent gain in December. Economists had been expecting a modest increase in industrial output in January. "We gave (U.S.) oil many chances to get above $98 and test $100 a barrel. And it becomes a situation where we can't rally, so we sell it," said Richard Ilczyszyn, chief market strategist at iitrader.com LLC in Chicago. The benchmark 10-year U.S. Treasury note fell 4/32 in price to yield 2.0104 percent.
