NEW YORK -- World stock markets rose on Tuesday led by gains in Europe and Asia as signs of progress in curbing the spread of the novel coronavirus fueled investors' appetite for risk, though a steep, late sell-off on Wall Street erased gains in US stocks.

New York state, the US epicenter of COVID-19, is nearing a plateau in number of patients hospitalized, Governor Andrew Cuomo said, a hopeful sign even as deaths in his state and neighboring New Jersey hit single-day highs.
Worldwide, the novel coronavirus has infected more than 1.3 million people and killed over 74,000, and although the numbers are still rising in many highly populated countries, some tentative improvements have given hope.
"The rally is sentimental and a little premature because if we lift these lockdown measures too soon and try to resume economic activity, we're going to get a very severe pandemic rebound," said Indranil Ghosh, chief executive officer of Tiger Hill Capital in London.
The comment echoed that of the World Health Organization, which warned earlier on Tuesday against easing coronavirus measures too early.

With market optimism on the rise, the US dollar dropped and riskier currencies outperformed as risk appetite improved on hopes that lockdowns may be slowing the spread of the coronavirus in some countries.
Action by central banks to ease a scramble for dollars has also helped bring some calm to markets, with massive US stimulus programs and debt issuance seen weighing on the greenback.
"We've got a nice decline in volatility across forex and equity markets," said Kenneth Broux, FX strategist at Societe Generale.
