Danceability Index

Joe Rothermich

The stock market and dancing are often based on the same thing: irrational exuberance. It stands to reason that by plotting the “danceability” of music against historical stock market data, one can predict stock market ups and downs based on the degree to which people are getting down. Based on the 84-year-old theory that the length of skirts correlates inversely to the performance of the stock market, the Danceability Index is built on the principle that a preponderance of dance-friendly music in New York City could indicate irrational exuberance on the part of investors. Even weirder, it works.
