Some fun facts:
-The longest run of positive returns is 9 years.
-9 year positive return runs happened 3 times, 1894-1902, 1991-1999, and 2009-2017.
-That means if 2018 is a positive return year, this would be the first 10 year positive return run ever in the 146 history of the S&P 500.
-The average and median length of positive return runs is 3.6 years and 2 years, respectively.
-The longest run of negative returns is 4 years, this happened once from 1929-1932.
-The average and median length of negative return runs is 1.3 years and 1 year, respectively.
-The best ever annual return is 56.8% in 1933.
-The worst every annual return is -44.2% in 1931. 2008 was second worse at -37.2%. But from 2000-2002 there was a 3 year run of negative returns totaling -43.4% (-9.1%, -12.0%, -22.3%).
-The average positive and negative annual returns are 19.1% and -12.3%, respectively.
-The average and median annual return for the entire 146 history of the S&P 500 is 10.8% and 11%, respectively.
These numbers really gave me a sense of appreciation for the power of and confidence in the free market capitalist system and index investing. This growth represents wealth generation in the economy driven by competition and the desire to improve our lives.
10.8% return per year, 3.6 year positive return runs and only 1.3 year negative return runs, passively, I’ll take that deal all day long. All I have to do is buy the S&P 500 and sit back and reap the benefits. If only we could figure out a sustainable way to operate it.
