A ton of ETFs bought SPCX yesterday (esp BlackRock via BIA w/ $450m buy). There were 4 ETF holders on Fri morning but now there are 40. Wild. I remember w META and BABA it took weeks for it to enter ETFs. Back then tho almost everything was passive governed by index rules. Today 60% of the products are active, and they don't have rules, can buy/sell whenever whatever pretty much.(Eric Balchunas)
