All three major indexes are on track for their worst week since the week ending March 20.

Rising infections in the U.S. and Europe could mean tighter restrictions on economic activity, dealing a blow to a fragile recovery.
Shares of hotels, airlines and other companies sensitive to the pandemic's impact sank.
Major European stock indexes also plunged as data showed the virus making a resurgence there. The sell-off spread to the U.S. market, where investors appear to be paring down their holdings ahead of election day next Tuesday.
Economically sensitive names like Caterpillar, Dow and Visa were among the biggest losers.
Boeing announced further job cuts in anticipation of a continued slump in aircraft demand. Microsoft was also down sharply after issuing a quarterly revenue forecast that missed analyst estimates.
New U.S. COVID-19 cases topped 80,000 last Friday and Saturday, reaching new highs. They remained elevated at the 70,000 level on Tuesday, with notable increases in the Midwest.
