interesting question, and i used the AI for help on this one:

$ value of equity purchased in indices:

- total market cap of those 3: $3.6tn

- index inclusion weights is based on free float, not full market cap

- free floats ~5%

=> 5% * 3.6tn = 180bn of these stocks in MV weight in the index

$ value of index funds: $18tn

$ value of market cap that is tracked by these index funds: $57tn

=> index funds are 18/57 = 31.6% of the market value

=> 180bn * 31.6% = $57bn of stock included in the index funds

so $57bn in sales in other companies => 57bn/18tn = 0.32% of all other stocks sold

Now for the assymmetry here:

- 57bn in sales is about 7% of daily volume for all incumbants combined

- 57bn in purchase is about 15-30 days of volume for typical stocks (hence Elon's eagerness to get them included asap)

If we’re going to have a Great Depression, this will be the trigger.

Every single fund autodumps billions in shares and is forced to buy slop. The dumping triggers the algorithm traders who dump. The dumping triggers manual traders to dump. The crashing causes retail to dump. Everyone dumps their treasuries and gold because they’re both crashing and they want cash.

And there’s no capability to raise money in any western country, because everyone is already loaded up to pay welfare bills.
