We looked at the history of the S&P 500 to find the 5 biggest bull markets, for those interested in tracking the market on their trading platform. The chart compares the length and size of the top 5 bull markets throughout the history of the S&P 500.
The tech boom bull market is the biggest and longest bull market ever recorded in the history of the S&P 500, returning a stunning 582% and lasting a total of 4494 days (12 years and 4 months).
This period of sustained growth started in 1987 and ended dramatically with the dot-com bust. It was fuelled by the end of the Cold War and the beginnings of the internet, which started to see the founding of tech companies. However, in 2000, the bubble burst and many dot-com startups went out of business, causing a fall in technology stocks and a consequent crash in the market.
The post-financial crisis recovery bull market was the second biggest ever and returned 401% over 11 years.
This bull market came off the back of the second biggest crash between 2007 and 2009, also known as the financial crisis caused by subprime mortgage lending, and was part of a long and slow recovery from this crisis when banks had to be bailed out. The period of sustained growth lasted 3999 days and came to a halt at the beginning of the coronavirus pandemic in early 2020.
During the period following World War II, there was another large bull market and the S&P 500 grew 266% as a result of global recovery after the war. This positive period lasted 2607 days, (7 years and 1 month) and is the only bull market on this list that came after a war.
Bull markets are typically seen in periods of global financial recovery, which often follow either market crashes or events that have a negative impact on the global economy.
The Reaganomics bull market saw the S&P 500 increase by 229%. A rapid period of growth occurred due to stark neoliberal economic policy throughout the Reagan era.
This bull market lasted 1839 days (5 years) and ended a few months before Black Monday in 1987, the worst day in the history of the stock market. On Black Monday, the S&P 500 dropped by over 20% in a day.
The mid-1970s to early 1980s bull market followed the oil shocks in the early 1970s and returned 125% by 1980. This period lasted 2247 days, (6 years and 2 months). Interestingly, the Reaganomics bull market was over a year shorter than the 1970s-1980s bull market, whilst returning almost double the amount of growth.
