Without the proposal, you'd have outrage out the other side that it wasn't included (especially if it shoots off like, well, a rocket).
And if they miss out on part of a runup, and the companies later enter the index, what is the long term "harm" if any??
But if they're "right" it makes the competing indices look weak.
We live in an age proving that valuation is just a manipulation.
This whole story is just like the BaM situation: the people with more money feel emboldened to pull every dastardly trick they can to tilt the table towards their pockets, away from the honest participants. SpaceX and the AI IPOs are just the latest and most grand scheme. I’m guessing you were surprised by the collapse of lehman brothers back in the day.
It’s and interesting point. I’ve done a bit of searching and am also empty handed.
I don't know how I could? The indices have already provided their reasoning for these rule changes, but that's just summarily rejected by the conspiracy-minded.
To laymen this appears to be a grand conspiracy. Rules are being changed to accommodate big companies, that's usually bad.
To people in the financial industry, it's fait accompli. The indices exist to reflect the market, these IPOs are going to be big enough that the 90s-era rules will/would result in untenable divergence.
