James Demmert believes this week's earnings will serve as a barometer for economic health. Companies like Walmart (WMT) and Target (TGT) will highlight whether Americans are willing to buy amid continuing uncertainty. Additionally, James mentions Toll Brothers (TOL) as an indicator to the housing market, the results of which will be watched closely by the Fed. He later talks about Ukrainian president Volodymyr Zelenskyy and other European leaders' visit to D.C. and its impact on international stocks.
