Index funds, for starters.
I don’t even have access to a NASDAQ fund in my 401K. You have to go out of your way to buy the NASDAQ 100, QQQ and /NQ or /MNQ futures are the most popular instruments for getting exposure.
I have a tiny minute slice of SPCX from owning VTI total market ETF but my 401K holds no SpaceX.
Contrary to (apparently) popular opinion, index funds are not people.
