When did the U.S. stock market bull market start?

The U.S. stock market bull market is generally considered to have started in March 2009, following the global financial crisis. After reaching a low point in the aftermath of the crisis, the stock market began to rally and experienced a prolonged period of growth and rising prices. This bull market was characterized by strong investor confidence, increased economic activity, and overall positive market sentiment. The bull market was fueled by a number of factors, including fiscal and monetary policy measures aimed at stimulating economic growth, corporate earnings growth, and low interest rates. Additionally, technological advancements and globalization also played a role in driving stock market performance during this period. The bull market continued for several years, with the S&P 500 and Dow Jones Industrial Average reaching record highs. However, it experienced periods of volatility and corrections along the way, including in 2011, 2015, and 2018. Despite these challenges, the bull market persisted and continued to set new milestones. The bull market came to an end in early 2020, as the COVID-19 pandemic and related economic shutdowns caused a sharp decline in stock prices. This marked the end of the longest bull market in U.S. history, which lasted over a decade. Overall, the U.S. stock market bull market that began in 2009 was a significant period of expansion and prosperity for investors, as well as a reflection of the broader economic recovery following the global financial crisis.
