Wall Street closes higher in broad rally

Stocks on Wall Street surged on Monday, bouncing back from the longest weekly losing streak in a year for the S&P 500 and the Dow.

All three major U.S. stock indexes ended the trading day higher, with the Dow, S&P and Nasdaq all rising more than 1.5%.

While Monday's gains were broad, the energy and financial sectors were among those with the largest gains. They are the very sectors that suffered the most bruising blows amid coronavirus shutdowns.

Yet despite stocks surging, Hilary Kramer of Kramer Capital Research says investors should be cautious.

"Investors should be extremely careful and one of the hints is that volatility even with this day when the stock market is up, volatility seems to be rising. So there is an expectation the market will see a leg down and there is a lot of concern out there about this week to come. We have employment numbers on Friday. But the big thing is what will happen at the debate on Tuesday night."

Tech giants Apple and Amazon gave the S&P and the Nasdaq the biggest boost Monday.

American Airlines also surged, helping to lift to the broader airline sector, which has suffered tremendously due to the pandemic.

American's rise came after the commercial carrier announced late Friday it had secured a $5.5 billion government loan and might have access to more funding.
