SPYis sp500 is it not? Why would they include it?

For others like qqq it has no bearing to be frank. It follows the nasdaq 100. Maybe an argument that the extra few months would have allowed more price discovery but I am not so sure.

float adjustment results in any CRSP tracking fund/etf having a $10,000 investment being approximately $17 worth of SpaceX. This isn't a real problem the media is trying to push it as.

CRSP is float-weighted!
