I've had multiple ppl suggest an S&P ex-SpaceX. Given there are two dozen SpaceX ETFs so far i'm surprised we haven't seen. That said, I bet it would flop. Most of the SpaceX angst is a tiny minority of terminally online ppl. Second, they tried an SPX ex-tech and no one cared. Third, there will be Inverse SpaceX ETFs which one could use to hedge out SpaceX for whatever time period they wanted. Fourth, Tesla went up 65% in first year after IPO, it may turn out to be a good thing.(Eric Balchunas)
