| There is some truth to it. 401ks and pension funds have large amounts of money in index funds. Major indexes like VTI will buy SpaceX after a waiting period as long as it satisfies other rules (and there have been some rule changes in various indexes to make something with low float like SpaceX eligible for inclusion). However, most indexes are float-adjusted, meaning that they will adjust the amount of shares of a company in the index based on their float, not their total shares. So, they will initially pick up small amount of weight/shares around the IPO. The NASDAQ-100 has been bending over backwards to cater to SpaceX, which makes some sense because they want it listed on their exchange. They changed their inclusion rules to include a fast-track for IPOs. This type of mechanism isn't uncommon in other large indexes (VTI has had fast-track rules for a long time) but the timing does make it appear that they changed their rules for SpaceX. Other providers have made changes to float requirements for inclusion. The NASDAQ-100 (QQQ being the popular ETF tracking it) is also not float adjusted and, instead, has some capping rules for low-float securities. I haven't done any projections but it seems that NASDAQ-100/QQQ will pickup more shares than the float-adjusted indexes. |
