Global shares held firm on Tuesday, with a solid foundation in place to extend their bull run to a 12th consecutive session as optimism about the global economic recovery and expectations of low interest rates drove investments into riskier assets. MSCI’s broadest index of Asia-Pacific shares outside Japan ticked up 0.1% while Japan’s Nikkei rose 0.4% to a 30-year high. S&P500 futures traded 0.5% higher to a record level. The mainland Chinese markets will remain closed for Lunar New Year through Wednesday while Wall Street was also closed on Monday. In the oil markets, prices soared to a 13-month high as a deep freeze due to a severe snow storm in the United States not only boosted power demand but also threatened oil production in Texas.
