Too short sighted.. I own both NIO and WKHS and I'm still buying MOON. It's tracking the S&P Kensho Moonshots Index, which existed before NIO and WKHS.
You're thinking too short term. This ETF will just grab the moonshoots and cycle them out when they're out of juice. NIO and WKHS still have large room for growth, but when they fall out of favor they'll be replaced. I'm not going to always be on top of the next moonshoots, but this index seems to be on top of that so I'll put my trust in it. I've gotten huge gains from NIO and WKHS and doing my on research on them has led me to that. In other words, you're actually making my confidence in MOON stronger contrary to what you believe you're doing. It shows that this ETF already follows the methodology I use for my stock picks, but they'll be better at it since I don't have the time or energy to always pick out the next best thing. I'll give you a moment to take a look at KMOON index and come back with a better understanding of what this ETF is trying to achieve.
