A gauge of global stocks hovered near seven-week lows on Monday as Asian stocks plunged on their first trading day after a long break, amid fears the coronavirus epidemic would hit Chinese demand.
Markets elsewhere showed signs of rebounding, however, after a selloff last week that pushed global stocks into negative territory for the year.

"The market seems to have reacted quite reasonably," said Pala Asset Management portfolio manager David Nietlispach.
"There is no panic and no selloff of securities that are unrelated to the coronavirus. The government interventions have been so heavy, though, that you will see an impact on the global economy."
Asian markets more broadly continued to sell off. MSCI's broadest index of Asia-Pacific shares outside Japan was down for an eighth straight day, falling 0.85% at 527.61 points, its lowest since early December.
Japan's Nikkei dropped 1% to the lowest since November and Australia's benchmark index ended down 1.3%.

A total of 361 people have died in China from the coronavirus. The first death outside the mainland was reported on Sunday in the Philippines.
GLOBAL SLOWDOWN

But a raft of global economists, including Citigroup, Nomura and JPMorgan, downgraded their forecasts for China's economic growth.
