1929 - 1933: The stock market crash of Oct. 29, 1929, marked the start of the Great Depression and sparked America's most famous bear market. The S&P 500 fell 86.1% in less than three years.
1946 - 1949: Less than a year after the end of World War II, stock prices peaked and began a long slide. As the postwar surge in demand tapered off and Americans poured their money into savings, the economy tipped into a sharp "inventory recession" in 1948. The S&P 500 lost 29.6%
1968 - 1970: Rapid-fire growth ended with a mild recession, accompanied by relatively high inflation of about 6 percent annually. The bear market began just as Richard Nixon was elected president after a tumultuous year of assassinations and riots. The weak economy added to a tense national atmosphere dominated by the growing U.S. involvement in Vietnam. The S&P 500 index lost 36.1%.
1973 - 1974: Israel's Yom Kippur War and the subsequent Arab oil embargo sent energy prices soaring, sparking a lengthy recession. The annual consumer inflation rate topped 10 percent. The Watergate scandal forced President Nixon to resign. The S&P 500 index lost 48%.
1980 - 1983: After nearly a decade of sustained inflation, the Federal Reserve raised interest rates to nearly 20 percent, pushing the economy into recession. A combination of high inflation and slow growth, known as stagflation, took grip. The S&P 500 index lost 27.8%.
August to December 1987: After a prolonged bull run, computerized "program trading" strategies swamped the market and contributed to the Black Monday crash of Oct. 19. The S&P 500 index lost 33.3%.
2000 - 2002: The bursting of the dot-com bubble followed a period of soaring stock prices and exuberant speculation on new Internet companies. Companies with little or no profits had market values that often equaled or exceeded that of established "old-economy" corporate giants. The S&P 500 falls 49.1%.
2007 - 2008: A long-feared bursting of the housing bubble became a reality beginning in 2007, and the rising mortgage delinquency rate quickly spilled over into the credit market. By 2008, Wall Street giants like Bear Stearns and Lehman Bros. were toppling, and the financial crisis erupted into full-fledged panic. The S&P 500 lost 56.4%.
2016 - 2018: The S&P 500 index rose around 36.0% due to Donald Trump's promise on historic corporate tax cuts.
