Asian stocks edged up on Wednesday as investors were guardedly optimistic about a "Remain" vote in Britain's make-or-break European Union referendum, while Federal Reserve Chair Janet Yellen's cautious tone virtually ruled out a July rate hike. European markets were also poised for a positive start, with financial spreadbetter CMC Markets expecting Britain's FTSE to gain 0.4 percent, France's CAC 0.5 percent and Germany's DAX 0.7 percent. MSCI's broadest index of Asia-Pacific shares outside Japan rose 0.4 percent. Japan's Nikkei trimmed its losses to 0.6 percent. China's CSI 300 index and the Shanghai Composite both advanced about 0.4 percent, while Hong Kong's Hang Seng reversed earlier losses to climb 0.5 percent. On Wall Street, U.S. S&P 500 Index gained 0.27 percent but was still below an 11-month high touched earlier this month. Fed chief Yellen said on Tuesday the central bank's ability to raise interest rates this year may hinge on a rebound in hiring that would convince policymakers the U.S. economy isn't faltering. "A couple of months ago, Yellen was cautiously optimistic. Now she appears cautious while trying to be optimistic," said Tohru Yamamoto, chief fixed income strategist at Daiwa Securities. "Judging from her comments, a rate hike in July is completely off the table. It is questionable whether the Fed can have enough solid economic data to back up a rate hike even by September," he said. The dollar slipped 0.2 percent against the yen to 104.57 yen, after a brief rally to 105.065 overnight as Yellen expressed general optimism about the U.S. economy. Yellen's more circumspect view on the future path of U.S. rates comes as many investors remain on the sidelines ahead of Thursday's British referendum on its European Union membership. Polls in recent days showing rising momentum for the "Remain" camp helped boost risk appetite in global markets and have weighed on safe-haven assets such as German bonds and the Japanese yen since Friday. But many investors are shunning trading as the vote remains too close to call, with an opinion poll published on Tuesday showing the "Remain" campaign's lead had shrunk. "We still have three polls on the U.K. referendum before the vote, and another shift back to Brexit will see risk appetite disappear in a jiffy," Bernard Aw, market strategist at IG in Singapore, wrote in a note. The British pound edged back to $1.4681 after climbing to as high as $1.4788 on Tuesday, its loftiest level since January 4. The implied volatilities of the pound have also pushed up from lows on Tuesday, reflecting investor anxiety over a sharp fall in the currency in the event of Brexit.
