(It was a common misconception on this thread: https://news.ycombinator.com/item?id=48364055.)
My prediction is that this will overall end up costing index holders money though. They will ultimately get a worse entry price for SpaceX and the other mega IPOs. Only time will tell.
The misinformation was almost certainly not taken into account, and it shouldn’t have been.
> everyone would be saying I told you so and screaming
Influencers will scream regardless. It’s what they’re paid to do. The NASDAQ 100 made these changes and is doing just fine.
> will overall end up costing index holders money though. They will ultimately get a worse entry price for SpaceX and the other mega IPOs
There are lots of indices. S&P largely targets those built around mature companies. If you want a total-market index, those exist and tend to rapidly incorporate IPOs.
That the rule change was a done deal. The pitch was some shadowy financial cabal forcing everyone’s retirement savings into SpaceX (which would not have been true even if S&P voted to include, but that’s a separate topic).
The top comment and most of its subthreads are run-of-the-mill alarmism.
Worth considering:

And the rules for the NASDAQ 100 were changed, as were MSCI and CRSP:
* https://www.schwab.com/learn/story/some-indexes-accelerate-e...
The doomsaying was around most retirement assets. Which don’t follow any single index. But to the extent they do, follow the S&P 500.
The market wasn’t pricing in any rebalancing. Commenters were screaming bloody murder about it. In the middle, I’m sure some numpties generated trading and management fees by switching target funds.
Sure. Nobody was properly making this distinction in social media, including on HN. Particularly with respect to the differences in scale and purpose between the NASDAQ 100 and S&P 500.
If you’re buying into a tech-marketed fund like the NASDAQ 100 and it doesn’t include a large chunk of the tech market, you’re no longer passively investing in tech. You’re investing in an actively-managed fund.
Historically, companies like SpaceX would have gone public earlier and grown into the index. Recognizing that has changed with multiple $1+ trillion IPO contenders makes sense; as it turns out, I think both NASDAQ and S&P decided correctly.
The preexisting ruleset was used by investors to gauge their portfolio balance.
Now investors have to revaluate their portfolio based on the new ruleset as their fundamental risks have changed.
Public decisionmakers do this sort of thing all the time. They "float an idea", "test the waters", "put up a trial balloon". They see what they can get away with. When the decisionmaker has a strong desire for the change, it may only get rolled back if powerful and widespread public dissent makes itself known, as it did in this case. When they don't really care about the issue, they might cancel it at the first sign that anyone has an issue. We can't know their degree of insistence just based on outcomes in these cases.
It was totally misinformed, came well after the public-comment period had ended and had zero net effect other than maybe generating some commissions and management fees for rando managers.
There is bona fide hatred for these companies and their managers. Influencers twisted the facts to channel that for views.
Great advice.
HN has been speculating on how wealth would be extracted from 401k and IRAs at least since the November elections in 2024.
Far before any influencers even thought this would be a thing.
I thought forced cryptocurrency funds, but it turned out to be something else.
I could kind of agree with the argument that "well these companies stay private longer so they are more mature" but the float exemption with the seemingly arbitrary calculation to figure out weights completely belies that argument.
It depends. Indices aren’t funds. They aren’t meant to balance investor interests. They’re meant to communicate some metric about the market.
The S&P tells you how big companies are doing in an index optimized to balance representation against trading cost. So in 2005, float was taken into account for weighting (versus just market cap). This made sense. Also, since the start, the S&P 500 has been a committee-based index. Not rule based. This has made it successful; if you want stable and unchanging, you never went for the S&P 500.
The rules around index inclusion exist for a reason. Too much control in one person's hands (which SpaceX has), too small a float (so you don't get price discovery), lack of a history of financial performance and minimal trading days just don't give investors confidence and, like it or not, investment decisions are made based on the index. If you want to argue against passive investment, well, good luck with that.
I think a lot of people have this weird idea that what we need is some theoretically unfettered market for "true" price discovery when it's actually regulations like this that create markets. It's like a libertarian brain worm.
I don't think anybody wants these mega-companies out of the index, specifically. They just don't see why rules that exist for a reason should be suspended when the net effect of that is that investors have less information and there is a lot of forced purchasing. If you have confidence in your IPO, let the market decide what it's worth without trying to fix the price because what they seem to want is for insider lock-ups to end about the time we'd otherwise be getting normal price discovery. Kinda weird.
Investor confidence needfs to be managed by creating a stable, regulated market.

Nasdaq clearly did it for the big bucks and getting the listing, why did Russell bend the knee?
Long listen but a very thorough and nuanced discussion by a bunch of smart investment / finance guys in Canada. No click-bait-sky-is-falling content.
This is not misinformation. Misinformation is saying the proposed rule change and their proximity to trillion dollar IPOs introduced no risk. Please do not spread such misinformation.
> That the rule change was a done deal.
What are you talking about? The rule has already been changed in the NASDAQ. That makes it a done deal.
Anything changed can always be undone, but to be clear it has already happened. That makes it a done deal.
Two other indices changed their rules to allow these companies specifically. Pensions and retirement funds rely on these indices to have continual, stable growth. Often the people whose money is being invested don't even have control over its allocation into these funds.
Coupled with the precarious state of the economy due to all the money already flowing through AI, changing the rules to throw retirement fund money into brand new extremely highly valued stocks with P/E ratios in the hundreds seems like a recipe for disaster. It reminds me of subprime mortgages.
One of which is the NASDAQ 100, marketed for decades as a tech-focused index.
> Pensions and retirement funds rely on these indices to have continual, stable growth
Pensions build their own benchmarks. About 10 to 20% of retirement assets follow these indices directly for a variety of purposes. The S&P 500 aims for continuous large-cap growth, but that isn’t true for most indices, which seek to replicate something random.
> changing the rules to throw retirement fund money into brand new extremely highly valued stocks with P/E ratios in the hundreds seems like a recipe for disaster
The NASDAQ 100 has seen practically no net outflows due to this decision. And most retirement assets don’t blindly follow any index, let alone any single one. I opposed the rule changes at S&P. But the catastrophising was made for clicks and views. Not to inform anyone.
Like, anyone who actually acted on that brouhaha changed out of an index that isn’t going include SpaceX, incurring transaction fees and potentially tax hits (for non-retirement accounts) in the process, and probably cycling into a higher-fee fund.
So why change? You're not building a case for why this change is needed. Is there even another Nasdaq 100 company like SpaceX? Probably not because it would be an obvious point of discussion. So now we need to add a new 'thing' to our definition of tech, then change our funds to adopt our new definition. To what end, with this haste?
> The NASDAQ 100 has seen practically no net outflows
Is it a fund or just an index? If an index, what are you monitoring when you cite 'no outflows'?
So you are happy with this outcome, but also so upset at the people that evangelized your preferred policy position that you think HN readers should cut them from the information diet?
Seems most likely that the public outcry actually influenced this outcome, so I don't see why the nuances of alarmism about it should nix an entire information source.
The valuation is insane and the very low float plus short timeframe for actual price discovery just seems built to extract money from index investors.
They can follow the same rules as everyone else.
It seems crazy to me to make a comparison between a company being valued on it's current profit and then to say it's reasonable for another company to have the same market cap because it could eventually have the same profit.
I see others are listening to the Money Stuff podcast ;)
This is a common misconception. The S&P 500 weights allocation by float-adjusted market cap, not by total market cap. In the case of SpaceX, they are planning to offer 4% of the company at IPO, and at a $1.75T valuation that's $70B in floated shares.
Even if SpaceX was added to the index, SpaceX weight would be ~0.125% of the index, not ~2.5% as you imply.
It seems entirely reasonable to say: "if we make a certain decision, we correlate both our reputation and a nontrivial portion of the U.S. economy with the whims of one of the most volatile personalities in industry, and we should likely pay attention to this trial balloon that shows such anticipatory fear of the decision that we might lose our reputation as an index altogether."
As a business, sure. As a committee, it’s still a deeply technical process. I can say with a lot of confidence that optics weren’t considered in any of this, possibly to a fault.
> and a nontrivial portion of the U.S. economy
This vastly overstates the amount of assets tied to the S&P 500. It’s a lot. But it’s a strong minority of equity exposures.
This is a big win for many S&P 500 etf holders
The longer major indexes exclude these companies, the further the index strays from representing the market, and the worse they do their core job of tracking it.
It's not the index's fault that market is pushing out overpriced and unprofitable companies.
So by that metric the very loud people succeeded: these new IPOs will enter the index under the established rules and time-frames.
