There should be a branch of academic finance which studies the dynamics of index funds when the index returns is dominated by a small percentage of assets.
The ivory coast vs Ecuador game was packed full of yellow jerseys, the Congo vs Portugal was packed full of red jerseys. I starting to see a pattern on who gets to attend those games and who does not.
I've come across one or two papers on this over the years but seems like it's not considered a major problem. A bunch of indices have a bunch of mandates which control their rebalancing dynamics, transaction cost and other things I know nothing about
Who on here is watching the world cup? I saw Germans in town yesterday for their game against Curaçao. People made it to the world cup but affluence is not as expected downtown was empty despite a big game like that.
what I love and hate about ai is that this is basically a sort of complicated autoencoder/nonlinear pca except it's a foundation model:
You can't be serious.
So what happens when a bunch of ponzi assets start dominating the index?

1/ Everyone is thinking in trillions. Some numbers to put $1T in context. One trillion dollars roughly buys:
50 days of the US federal government
1 year of US federal interest on the debt
90 days of Chinese government spending
5 months of gov spending in Germany
6 months of gov spending in France
