Top tech performers in Japan rose by up to 4%, led by computer giant Fujitsu, chip maker NEC Corporation and semiconductor equipment supplier Adventest. Investors ignored Ministry of Finance data, which showed the real corporate world was still looking grim. Profits of Japanese companies slumped 33% in the three months to the end of September as sales fell 2.6% and capital spending came to a virtual standstill, up 0.5%. Manufacturing profits were worst hit, and fell more than 52% to their lowest since 1975, the ministry reported.
