Asian stocks stumbled to seven-month lows on Monday, while crude oil prices were pinned near a four-year trough as promising trade numbers out of China failed to cheer a market still worried about faltering global growth. MSCI’s broadest index of Asia-Pacific shares outside Japan fell 0.8 percent, extending last week’s 1.1 percent drop. Mainland Chinese stocks skidded 1.1 percent and Hong Kong’s Hang Seng shed 0.7 percent. Tokyo’s Nikkei was spared the pain for now thanks to a public holiday in Japan.
