Asian stocks fell on Thursday as disappointing earnings forecasts from Facebook parent Meta Platforms hammered tech shares, while the yen's slump past 155 per dollar for the first time since 1990 raised the spectre of intervention from Tokyo. The predictable hit to Asian tech stocks took MSCI's broadest index of Asia-Pacific shares outside Japan down 0.7%. Japan's Nikkei slid 1.3%, while China stocks also fell, with the blue-chip CSI300 index down 0.3% and Hong Kong's Hang Seng Index 0.5% lower.
