BEIJING (AP) — Asian stock markets gained Monday after coronavirus vaccine maker AstraZeneca agreed to increase supplies to Europe amid rising worries about the disease. Tokyo, Hong Kong and Seoul advanced. Shanghai declined after surveys showed Chinese manufacturing weakened in January. On Friday, Wall Street’s benchmark S&P 500 index lost 1.9% after GameStop, a video game vendor, and some other shares that were expected to decline were sent soaring by day traders. Other investors said hedge funds that bet against those stocks were losing money and selling other shares.
