Stock market performance post-pandemic bottom and Yellen's potential action on banks.

Three years after hitting its COVID-19 pandemic low, the S&P 500 has risen nearly 76%, while the Dow Jones Industrial Average is up 72.3% and the Nasdaq Composite has advanced over 70%. The Federal Reserve's support and the quick development of COVID-19 vaccines limited a further downturn in stocks. Energy has been the best-performing sector over the past three years, while First Republic Bank has been the worst performer in the S&P 500 since March 2020. The three major indexes all suffered their worst year since 2008 in 2022 due to rising interest rates, market-moving events, and global tensions.
