Asian stocks poked into positive territory on Tuesday, shrugging off early losses as Chinese shares stabilized a day after marking their biggest loss in a month and crude prices took back some lost ground. MSCI’s broadest index of Asia-Pacific shares outside Japan was up 0.1 percent. China’s blue-chip CSI300 index added 0.3 percent, while the Shanghai Composite Index was up 0.2 percent, after both skidded more than 2 percent in the previous session.
