Yep, there'll be index funds and others needing to add AKE due to the S&P rebalancing. My understanding though, is that most have clauses that allow them to alter holdings within period "X" rather than from or before a specific rebalance date.
Notwithstanding, there should be net buying around now and for the next few weeks to bring AKE into some required funds. Hopefully that aligns with continued strong prices for all lithium based products, supply and customer chains and we can really enjoy a decadent NYE. ;-)
