The new stocks are still going in, they're just going in after a year (the normal rules), rather than 5 or 15 days. The outrage here wasn't that the stocks were going into the indexes at all, it's that they were going in before price discovery, several quarters of earnings, more float, and expiration of insider lock-up periods, which seemed especially sketchy because of the (correct or not) perception that these IPO valuations are inflated and unrealistic. It seemed like they were trying to dump the bag on the public.

It seems the general consensus on HN is that they are overvalued and for sure will collapse in value down the road, I could imagine some frustration down the road if these companies actually become, say, 4T by the time they get added to indices.

There are different indices if you want to be exposed to that risk.

What examples have there been in the past of a company which did all its growth in the 1-year period following the IPO, then stopped right when they were added to the index?
