As coronavirus infections surge in the U.S., fears are rising that the momentum of the nascent economic recovery may be stalling after a sharp initial rebound in May and June.

U.S. equities surged higher last week, closing out one of the strongest market quarters in decades, as U.S. employment data continued to show swift progress in the recovery of the labor market through June.

U.S. equities tumbled lower last week as a surge in new Covid-19 cases in several regions caused some state and local governments to pause or roll-back business reopening plans and implement stricter social distancing measures.

U.S. equities rose higher last week despite reports of spikes in Covid-19 cases in some states and disappointing jobs data as markets were buoyed by the Federal Reserve’s corporate bond purchase program announcement and a stronger than expected rebound in May consumer spending.

Stock markets around the world suffered their worst weekly losses since mid-March last week, ending a three week stretch of strong gains, as investor sentiment was dampened by an acceleration in new Covid-19 cases in more than 20 U.S. states and by a cautionary message from the Federal Reserve at their monthly meeting that highlighted the potential for a more drawn-out, uneven recovery, including a long road back for the labor market.
