This is a great technical point, and in a scenario where a constituent has a lot of obvious correlations it might be relevant, but when you've got something that is effectively a meme stock with erratic leadership and a huge range in possible outcomes from bankrupt to most valuable company ever in the universe [claude tells me I should say 'idiosyncratic returns' instead of this rant], I don't see how you promise to match the performance of an index where it's a significant component except by buying it.
