Nikkei leads Asian stocks higher as investors cheer Yellen news
Japan led Asian stocks higher on Wednesday as investors cheered news that President Obama will announce Janet Yellen as the next chair of the Federal Reserve.
Yellen is widely perceived as being more dovish on monetary policy and investors expect her to take a slower path towards a reduction of the Fed's bond-buying program. The announcement is scheduled for 3pm ET on Wednesday.

"The main thing is that Yellen is seen as having policies in line with [current Fed Chairman Ben] Bernanke," said Stan Shamu market strategist at trading firm IG. "The news might temporarily take traders' minds off the budget stalemate and debt ceiling - certainly it does look like it will give markets a kicker today."

At a press conference on Tuesday, President Obama repeated that negotiations on spending could only begin once Republicans raise the debt limit with no conditions.
Following the comments, the Dow and S&P 500 hit one-month lows while the CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, rose 5 percent to its highest level in seven weeks.
