Resolves YES upon an accepted update to the following table on Wikipedia https://en.wikipedia.org/wiki/List_of_largest_daily_changes_in_the_S%26P_500_Index#Largest_percentage_changes with a drop of more than 8%. If no such update is made, resolves NO.

If Wikipedia becomes unreliable during this time (i.e. the article is abandoned, removed, or Wikipedia's reliability as a source comes into serious question), I will resolve this using my own assessment. I do not expect this to happen, and if it does, I do not expect my resolution to be controversial.

According to the aforementioned Wikipedia table, this would have resolved YES for only 7 years in history, i.e. 1929, 1932, 1933, 1937, 1987, 2008, and 2020.

Since I believe that the resolution of this market will be very objective, I may participate in it.

predicted YES

due to the dollar index rising by a huge amount so rapidly, the probability of a black swan event is quite high. Europe energy crisis gets worse, Ukraine war gets worse, fed hikes even further and breaks something else, lots of options for what can happen.

predicted NO

@CalebMoore This is a 7 sigma event.

@MP According to market pricing of the VIX, we should expect daily price moves to have a standard deviation of 2% (and a mean of 0% by the pricing of the S&P itself). i.e an 8% move would be a 4-sigma event.

@NicholasCharette73b6 (although note that the VIX is only measuring implied volatility for the next 30 days, not the whole year.

I guess this market is buying/selling something like put options on the S&P. Should expect the market probability to be higher than the actual prediction, because people pay a premium for insurance.
