Today is expiration day, so expect a lot of volume.
Two things happen today: the so-called triple witching, or the quarterly expiration of stock and index options and index futures, and the S & P 500 quarterly rebalancing, where additions and deletions to the S & P are done.
The effect of the triple witching has been greatly reduced due to the tremendous growth of weekly and monthly options that have been big competition for the quarterly expiration.
The S & P rebalancing will see Palo Alto Networks go into the S & P 500, and Dish Network relegated to the small-cap S & P 600.
This is also the day when index funds — such as S & P 500 index funds run by Vanguard, State Street, iShares, etc.
Organizations:
Palo Alto Networks, Dish Network, Vanguard, Apple, ExxonMobil, Meta, Nvidia
Locations:
