Asia equities were mostly higher on Wednesday, mirroring gains of their U.S. peers, while reports of bond purchases by the European Central Bank also lifted sentiment.
On Wall Street, the S&P 500 and the Nasdaq posted a fourth session of gains overnight. Both indices rallied 2 percent while the Dow jumped more than 1 percent after existing home sales in September hit a one-year high.
Reports that the European Central Bank is considering buying corporate bonds were in focus. The move would add to covered bond purchases the bank began this week and may be a step closer to full-blown quantitative easing, said Stan Shamu, market strategist at IG in a note.
"The market would really want to see government bonds and high-quality private debt included in a broad-based asset purchase program," he added.
