Unfortunately that fund holds around 40% of its capital in TSLA alone and only ~5% in SpaceX, so not a very good choice for investment. It also uses leverage. Great choice if you believe in Elon, not so great choice if you have any semblance of risk management.
Presumably someone could take other positions to hedge away all of the other holdings in the fund so that (to a first order approximation) their only exposure is SpaceX, right?
