A weak yen also lifted the investor sentiments as it slipped to 94.46 per dollar, its lowest level since May 2010. Earlier, the US Treasury official Lael Brainard praised Japan's efforts to boost growth indicating support for the country's monitory easing policies at the upcoming G20 meeting.

The Dow closed 0.16 percent lower while Nasdaq ended flat in the previous trading session.
