Dow Jones Makes Market History

The financial media reported the Dow Jones made market history Monday when the Dow moved 1,089 points on an intraday basis from the previous day’s close. After a brutal day, “a new historic record” like that sounds pretty darned impressive. However, this history-making event was largely an inflationary illusion, although the media and most retail investors would never see it that way. Yes, during the 1930s, the Dow Jones never saw an intraday move of a thousand points. Of course not. How could it when at the absolute top of the Roaring 20s bull market, the Dow Jones reached a peak of only 381.17 (03 September 1929)? But can there be any doubt that investors endured worse days during the Great Depression crash than we saw on Monday?

In the past ninety-five years, the Federal Reserve (created by our own Congress), has issued over 300 dollars for each dollar already in circulation in January 1920. In effect, “monetary policy” has eroded 99% of the purchasing power of the 1920 dollar. This horrendous inflation makes historical comparisons in nominal dollars nonsensical. Therefore, comparisons of historical market events separated by decades are best done using percentages.

The following chart shows all the days with a 5% intraday swing (or greater) on the Dow Jones since October 1928. Some of these days the Dow Jones declined, others it advanced, but they are all rare market events. In the past eighty-seven years, there have been only 346 such days. The largest percentage swing occurred on 19 Oct 1987, when the Dow moved from a daily high of 2,164 to a low of 1,677. That was a point swing of only 487 points, less than half of Monday’s 1,089. But when we do the math, it’s apparent that Monday’s 1,089 point swing from its daily high to low resulted in only a 7.08% intraday move, while on 19 October 1987, actual history was made with a 29% percentage intraday swing.
