The fiscal aid includes direct checks to millions of Americans, aid to state and local governments, funding for Covid vaccines and testing, a boost to the minimum wage and enhanced unemployment benefits, among other things.Lindsey Bell, chief investment strategist for Ally Invest, noted any additional stimulus could lead to a surge in inflation.”Right now, watch for signs of inflation as a temporary or more long-term trend. If it’s just a quick shock, we may see some market weakness without any major Fed action,” she noted. “On the other hand, persistently high inflation may force the Fed to consider raising rates and pulling back their market support.” In an inflationary environment, Bell said investors should favor the consumer staples, energy and financials sectors. She added that real estate and gold are among the other assets that can help hedge against inflation.This coming week 13 Dow components and 111 S&P 500 companies are set to report earnings.

Hatzius cited consumers remaining more cautious than expected as well as the evolution of a vaccine-resistant virus strain as potential futures headwinds for the market.Biden’s surgeon general pick said Sunday that the U.S. is racing to keep up as the coronavirus mutates.”The virus is basically telling us that it’s going to continue to change and we’ve got to be ready for it,” Dr. Vivek Murthy told ABC News’ “This Week.””We’ve got to number one, do much better genomic surveillance, so we can identify variants when they arise and that means we’ve got to double down on public health measures like masking and avoiding indoor gatherings,” he added.Subscribe to CNBC PRO for exclusive insights and analysis, and live business day programming from around the world.
