As soon as the United States took a hit from the COVID-19 pandemic, so did the economy on a macro level. Businesses were, well, losing business, so unemployment was higher than ever. International travel and trade sank, causing gross domestic product (GDP) and inflation to take a dive. After experiencing these catastrophes, the Federal Reserve not only abundantly increased federal stimulus to businesses and individuals but also decreased interest rates, and thereby, the 10-year treasury yield. 

At that same time, the S&P 500, a major index of the stock market, was giving investors a scare with a 9.5% drop on March 12, 2020, and an 11% drop 4 days after that. However, that was the worst of it as the low rates, stimulus pouring in and bond buying largely helped the stock market recover back to pre-pandemic levels in August 2021.

Read this edition of Benzinga Reports for an in-depth look at how the S&P 500 has been related to the economy on a macro level for the last 50 years. Discover how economic trends are reciprocated across all indicators, such as inflation and the 10-year treasury yield, in addition to whether S&P 500 returns and earnings are always related.
