TOKYO, June 22 (Reuters) - U.S. stock futures erased losses and Asian stocks held flat on Monday, trying to shake off worries that rising coronavirus cases in the United States could scupper a quick economic rebound from the massive downturn triggered by the pandemic.
U.S. S&P 500 futures ESc1 rose 0.4%, having erased early losses of 1.05% while Japan's Nikkei .N225 also eked out gains of 0.1%, similarly recovering from early losses.

After a brutal sell-off earlier this year, share prices had risen globally over the past three months, helped by massive stimulus around the world and hopes the worst of the pandemic was over.

"Whether there will be a lockdown may vary depending on region. It will be a tough decision for politicians. But they probably have no other choice if they are running out of hospital beds," he said.
The pandemic is accelerating globally with the World Health Organization (WHO) reporting a record increase in global coronavirus cases on Sunday. market has been pricing in a rapid recovery so I doubt there are much upside gains to be made. We now need to see whether the earnings outlook will meet up with expectations," said Takuya Hozumi, investment strategist at Mitsubishi UFJ Morgan Stanley (NYSE:MS) Securities.
The world's shares are now traded at the most expensive levels since 2002 compared with projected earnings in the coming 12 months.

Kong's Hang Seng .HSI fell 0.3% in early trade, underperforming regional markets.
