Oh Veruca. Since you are trying to compare the drop in the DOW across all of US history, you must account for the size of the DOW Jones. In order to make it a more reasonable comparison, you should look at the percent drop when comparing across different time periods. With that in mind let's look at the top 7 largest daily drops by percentage in US history
Oh Veruca, you know how so, but I will explain it because I don't mind embarrassing you. Looking at the total number and comparing across time is a misrepresentation because it doesn't take into account the starting point or the overall size of the market during the drop.
To do this right you should look at the one day percentage drop
With that in mind here are the top 7 largest percentage drops in the DOW Jones
1) October 18, 1987 - 22.61% drop Black Monday - global crash
2) October 28, 1929 - 12.82% drop - Start of great depression
3) October 29, 1929 - 11.73% drop - Black Tuesday
4) March 16, 2020 - 12.93% drop - COVID 19 panic selling
5) March 12, 2020 - 9.99% drop - COVID 19 panic selling
6) October 26, 1987 - 8.07% drop - Aftershock of Black Monday
7) March 9, 2020 - Start of COVID 19 related selloff
So when you look at these honestly, the 7 biggest percentage drops centered around three distinct events. The start of the Great Depression, COVID 19 and Black Monday
Now this would have been an honest portrayal of the data if one is an honest broker. So the question then becomes. Are you ignorant of how to honestly present data or were you purposefully being dishonest? Which is it Veruca?
