TOKYO (Reuters) - Asian shares advanced on Tuesday, helped by rising optimism on the technology industry and easing concerns over North Korea, while the dollar edged up to one-month high versus the yen.
MSCI's broadest index of Asia-Pacific shares outside Japan was up 0.1 percent, with many of the region's markets reopening after a long holiday weekend.
Japan's Nikkei <.N225> rose 0.3 percent.
On Wall Street, although the Dow Jones Industrial Average fell 0.13 percent on Monday, the S&P 500 gained 0.17 percent and the Nasdaq Composite added 0.73 percent to a record closing high.
Notably, the world's five largest companies by market capitalisation -- Apple , Alphabet , Microsoft , Amazon and Facebook -- all hit intraday or closing highs - or both - on Monday.
"For those large shares to rally to record highs at the same time, you really need a big amount of money flowing in. It is fair to assume the money that was once staying in the bond markets are now going to hi-tech shares on back of their strong earnings," said Norihiro Fujito, senior investment strategist at Mitsubishi UFJ Morgan Stanley Securities.
