(Bloomberg) — U.S. equity-index futures fluctuated while stocks in Europe and Asia dropped on Wednesday as investors fretted over fresh evidence of the widening coronavirus outbreak. Gold advanced and Treasuries were steady.Futures on the three main American equity gauges swung between losses and gains, a day after the S&P 500 Index fell 3% to cap its worst two-day slide since 2015. The Stoxx Europe 600 Index dropped for a fifth straight session, suffering its longest losing streak since July, as companies including Diageo Plc and Danone SA warned the virus outbreak will hit sales in China. Italy and France reported fresh cases, while Spain locked down a resort hotel in the Canary Islands with 1,000 guests and workers inside.South Korean and Australian stocks led declines in Asia, with the won falling back toward its weakest since 2016 as the country emerged as a hot spot for the contagion. Ten-year Treasury yields hovered close to their record-low close set Tuesday, while the dollar edged higher. Risk assets are showing few signs of rebounding as coronavirus cases steadily climb outside the epicenter in China. South Korea said its national total rose to more than 1,000, while American health officials Tuesday warned that they expect the epidemic to spread in the U.S. Traders may be looking out for further signs of policy accommodation after American central bankers said they are closely monitoring the spreading virus, though it’s “still too soon” to say whether it will change the outlook.“The ultimate impact remains entirely unknown at this stage,” said Eleanor Creagh, a Sydney-based strategist at Saxo Capital Markets. “And uncertainty is the enemy of conviction.”Elsewhere, West Texas-grade crude oil slipped below $50 a barrel. Industrial metals and minerals mostly dropped, including copper and iron ore.These are some key events coming up:Earnings keep rolling in from companies including: Baidu Inc., Best Buy Co.
