TOKYO, Nov 5 (Reuters) - Japan's Nikkei average jumped 3 percent on Friday, led by short-covering and gains in resource shares after the Federal Reserve's plans to buy more Treasuries prompted investors to seek risk elsewhere, prompting rallies in global stocks and commodities.
Japanese stocks built on sharp gains made the day before, with the benchmark Nikkei now poised for a rise of about 4.7 percent on the week. If it books a weekly gain of more than the 4.19 percent hit in mid-September by the close, it would be its best week in a year.
The benchmark Nikkei rose 280.69 points to 9,639.47, while the broader Topix gained 2.5 percent to 836.73. (Reporting by Aiko Hayashi; Editing by Joseph Radford)
