Retailers including Walmart Inc WMT.N, Home Depot HD.N and Target Corp TGT.N are due to report their quarterly results this week. China's economic activity cooled sharply in April as widening COVID-19 lockdowns took a heavy toll on consumption, industrial production and employment, adding to fears the economy could shrink in the second quarter. Investors have been worried that aggressive interest rate hikes by the U.S. Federal Reserve to combat decades-high inflation could tip the economy into a recession, with the conflict in Ukraine, supply chain snarls and the pandemic-related lockdowns in China exacerbating the economic troubles.
