Dow Jones Stock Market Historical Correlations

Last updated: 2017-10-20

This page is updated every trading day at about 4:30pm EST with historical correlation charts for daily closing prices of the Dow Jones Industrial Average ("DJIA").

When the closing price for the DJIA becomes available, the program will iterate over 32,000+ historical DJIA closing prices (dating back to 1896) to find the historical periods with the highest statistical correlation to recent closing prices for a number of observation lengths.

The three (3) most highly-correlated historical periods for each observation length will be charted (in red, using the right y axis) along with the most recent market activity (in blue, using the left y axis). In addition, the historical periods will be extended by 50%.

I want to stress that historical market correlations do not predict the path of future market moves. My background is primarily in technology, marketing and research, but I do track the "markets" for entertainment value. I developed this tool because I could not find a solution to automating the charting (though I am sure they exist).

Tom McClellan pointed out that Pearson's correlation coefficient is ill-suited for longer time-series data. Yet, I still look at these every now and then.

N.B. Given the large number of charts and data points, it may take a while for this page to load on mobile browsers or slow computers.
