Well it’s just the S&P. Other big indices may include it eg the Russell 3000. But it’s not quite as big of a deal as it seems because the market cap on which they scale is the float not the whole value of the company.

You'll eventually get exposure to it when it gets added in 12 months. Unless there are better profitability criteria. Ultimately it's all about market returns. If other indexes add it and outperform then eventually money will shift to those funds that do better.
reply
It's not just about returns, it's also about risk. The role of a passive index fund is to be a passive index fund. If the s&p starts chasing returns, that will reduce its utility to the market. You get higher returns by being compensated for risks that passive investors/retirement funds don't want to take. And active investors use the S&P and similar indexes for the specific risks and asset class exposures they provide. You might think the economy is going to do poorly which would be good news for some company that's anti-correlated with the economy but you need to hedge that bet for if the economy does well, so in addition to buying shares of whatever that company is you buy into some market reflectiong mix of stocks bonds etc. The role of that hedge is to have a counterbalancing asset that moves opposite your primary bet to reduce volatility, and the role of the s&p 500 is to broadly reflect the american large cap publicly traded stock component of the market. If the S&P 500 begins behaving unpredictability to chase returns as an index then buying funds that track that index is no longer doing what you need it to do. S&P index loses utility, active investors just use some other index, but passive investors with 401ks locked in to tracking the s&p are suddenly forced to buy whatever bet the index creator is making en masse driving the stock price up. That's not a good outcome for anyone except the company muscling their way in and anyone that was somehow rewarded by that addition

What do you mean "better profitability criteria"? I don't want an index to exclude companies on the basis of profitability. I want it to hold the market.

That's like saying that if Nvidia performs way better than an index fund, then the index fund will shift to consist only of Nvidia.

In any given year, there are plenty of index funds that outperform the S&P 500. They don't freak out over it.

S&P 500 is volatile over 5 years - I'd argue even over 10 years (see the charts at https://blog.nawaz.org/posts/2015/Dec/pay-down-mortgage-or-i...). The whole point of investing in it is for much longer windows.

So yeah, perhaps after 10 years they'll change once they'll see other index funds doing better, and have data to back up that in the long term, early inclusion didn't hurt.

That is what looked like the catalyst but seeing the response made me feel the confirmation from the S&P really was a big factor, particularly because the algorithms must all have been banking on the rapid inclusion for the AI companies which would keep the tech ship afloat at its current valuation.

Yes, very easily, American households alone plop a few hundred billion to over a trillion dollars into the stock market every quarter. Whether investors want to is another question. (The answer, at least to the tune of $75bn for SpaceX, seems to be yes.)

reply
What I mean is that investors don't want to pony up the cash at current market prices. They want a discount. Then they will pony up the cash

Just like creditors demand higher rates on investment grade bonds, investors are demanding a higher risk premium if they're going to be expected to keep piling in cash to this particular sector that's diluting and raising.

There is never a singular reason. But there are negligible reasons. S&P not changing its rules was a negligible reason for today's tanking.

But how can you quantify that? There is no way to prove it, the market cannot say "I wasn't moved by this, I was actually moved by that and this part was actually just negligible."

Isn't it all subjective in the end because nobody really makes their trades with verifiable notes expressing the exact reason. So we can only guess right?

reply
> how can you quantify that?

Precedent and timing. Rates-related news is always going to massively shift the market, and the market shifting right after the jobs report is a pretty clear signal.

Moreover, S&P holding course wasn't new information–there was zero evidence of anyone pre-trading a rebalancing, which means the market didn't expect S&P to materially change its rules.

The strong job numbers too.

On a side note, I find it very sad that strong job numbers make stock plummet.

It really is an indication that the stock market is mostly speculative and not concerned about the actual economy.

reply
> It really is an indication that the stock market is mostly speculative and not concerned about the actual economy

Not really. Strong jobs numbers in the midst of 3+ percent inflation means rates should go up. That, in turn, dilates time on future earnings. So making a company's future earnings more-heavily discounted will be a net drag on valuations even if the jobs numbers indicate those numbers, near term and far, will be higher.

reply
Yep. Job numbers are the “actual economy” – the actual economy is driven by wages and consumption.

Stronger wages → stronger consumption → higher demand-pull inflation.

But higher inflation implying that “rates should go up” is central bank doctrine. It’s not a general law of how economies function.

Central banks intervening with interest rate adjustments is what distorts the prices of equities downward, when inflation rises.

Without central bank intervention, inflation should theoretically push equities higher (a highly-inflated economy driven by rising demand is by definition a well-performing economy!).

Central banks intervene because runaway inflation can be harmful to wage-earners (they save in dollars, not assets).

But I’m not sure if a 2–3% inflation target is ideal. It seems to me that this arbitrarily low inflation target restricts the growth of the economy in ways that might affect wage-earners, defeating the stated purpose of monetary policy, since higher rates also have the effect of curbing job growth as well as raising the cost of servicing mortgages.

reply
Agreed about the 2-3% target. Seems like a crazy low target for a country that has been, historically, a strong exporter. Or at least seems to want to be an exporter. I wonder if one of the reasons behind this low target rate is that inflation will ultimately decide how expensive government debt is, since under normal circumstances people will want their bonds to at least pay out enough to cover inflation.
reply
> But higher inflation implying that “rates should go up” is central bank doctrine. It’s not a general law of how economies function.

Let's put it this way then: the central bank can raise rates or it can crash the economy into a brick wall. In that sense, rates should be raised. We have the least competent regime in history right now though, so they might choose the latter option.

reply
> higher inflation implying that “rates should go up” is central bank doctrine

Uh, no. If you have no central bank, more consumption and more employment means more demand for money. Ceteris paribus, that will raise rates. (Our own history with free banking is more complicated since the only inflationary period was driven by specie introduction from California's gold rush. The predominant problem in antebellum America was deflation and bank collapses.)

You're correct inasmuch as central banks quicken this reaction, and–when done properly–dampen it. But the fundamental engine is emergent, at least for nominal rates.

reply
> not concerned about the actual economy.

Why would it be? Non dividend stocks only have value because other people think they have value (i.e. greater fool theory).

Only dividend stocks have some base value connected to how well the company does. (Higher dividend if it does well, lower if it does poorly.) But they still also have a lot of "greater fool" value.

Beyond dividend, stocks have no intrinsic value. Nowadays you don't even get a piece of paper to wipe your ass with anymore, it's all digital.

reply
> Non dividend stocks only have value because other people think they have value (i.e. greater fool theory)

Alphabet buys back shares equal to the GDP of Uganda every year. There are more ways to return capital than through dividends.

reply
what happens when ALL the stocks have been bought back? what is the natural conclusion? you get extra points if you mention dilution i.e. oops we turned on the ~~money~~ stock printer and your stock is now actually worth less!
reply
> what happens when ALL the stocks have been bought back?

This can't happen in practice. It would require the company's value to fall below the buyback amount, which is itself a fraction of the company's cash and thus value. (Like, yes, I could engineer a weird failing company where this could happen. But that would just be describing a peculiarity of how the company failed. If the company is doing fine, this doesn't occur.)

If you have trouble with a public-market buyback, consider how tenders are done in private markets. You're a shareholder who has the option of selling back your shares. It's a direct way for you to tap the company's treasury as a shareholder. The company's shareholders could vote to distribute all the cash and assets in a buyback. But we have a word for that: liquidation.

reply
> Only dividend stocks have some base value connected to how well the company does.

That's not how it works. If the company has profits they can distribute it in many ways. Dividends is one, but not a great one because it forces you to pay taxes on it this year. Or they can buy back shares which increases the share price, which is better because then you don't have taxable income on that until you decide to sell. Or they can reinvest that money into the business to grow it, which is the ideal option, although not always possible.

reply
Every time I try to explain this to people I feel like I'm talking to a brick wall. Even more frustrating to hear, otherwise reasonable, market analysts say that "dividends don't matter because the stock value goes down on payout". What doesn't matter is how successful a company is if they don't share their profits. You're literally buying a Pokémon card just with a lot of liquidity until the illusion of value bursts, hoping that somebody will buy you out because P/E improves or whatever.
reply
They do have intrinsic value!

Growth stocks trade on a multiple of earnings: earnings have intrinsic value.

reply
To who? There's no immediate benefit of holding a stock that doesn't pay out beyond voting rights, or a fraction of company assets. As parent said, you're just hoping to sell it to somebody down the line for more. It's speculation. The market is liquid, and a lot of people believe these stocks have value, but it's still speculation.
reply
That's just dividend stocks with more shady. We promise to invest the dividend you would have gotten into ourselves to become more valuable bro. But that will only be reflected in "valuations" that don't directly affect your bank account. It is still the greater fool theory.

The worst is growth stocks that are a wrapper around actual dividend stocks. Beyond number going up, what actual concrete utility are you getting? Beyond waiting for the line to go up to eventually sell it to a greater fool, what can you _actually_ do with it? It's not real.

It is only real because enough people believe it is real. And they believe it because they want to believe it, because they are greedy and want easy money.

Once the market tanks and the greed turns into fear, there will be bagholders and the brokers will be laughing. The people who skim fees and percentages will be cozy.

"Now is the time to invest" they will say, because from here the line can only go up! And it will, eventually, because people want to believe, because they are greedy.

The only thing the stock market makes money on is greed. That is the thing that drives stock value. Not the economy.

reply
This take makes sense but isn't really accurate. A lot of companies have stock buy back programs in lieu of dividends; essentially, using their cash flow to manipulate their stock price instead of returning money to every investor. Now this doesn't guarantee a particular price usually, but does help push the price up when they are buying a significant amount from the market.
reply
These companies are capex heavy and need to reach into the capital markets to sustain their growth. The cost of capital is correlated with inflation. Why is this the fault of the stock market? Maybe blame the government for diluting the money supply?
reply
Strong job numbers with rising inflation means potential hikes to the federal funds rate which increases borrowing costs which reduces profitability which means stock prices go down. Strange causality chain, but that’s how Mr. Market thinks.

I suspect if in 12 months these megacaps are still megacaps, they will revisit the profitability rules. It's hard to have an index with 500 of the largest, most significant companies leaving out companies with trillion dollar market caps.

reply
Seasoning and profitability rules are why S&P does not have as steep of a drawdown or as long as a recovery as Nasdaq over the last 30 years of market performance.

The S&P recovered from Dotcom bottom in ~7 years while the Nasdaq-100 took 15 years. Likewise Nasdaq took 3.5 years and the AI hype to recover back to its COVID highs in 2024 while S&P had the same recovery in about 2 years.

This is the downside to Nasdaq having higher returns in tech bull markets.

So the indices have a very different volatility profile by design, we should be happy to have the choice rather than have them all converge to the same product.

"OK, the rule should be you have to be profitable OR have an HQ in a city with two vowels in its name".

Did it really used to require that you own "15 railroads" ?

reply
The commenter is likely referring to the original S&P 90, which mandated a certain number of stocks in different sectors. At the time those numbers were 50 industrials, 20 utilities, and 15 railroads. The breakdown shifted as the economy changed until the 80's when they did away with sector quotas in favor of rules closer to today (basing allocation on market cap).

Regardless, the S&P 500 also excludes a company like Microstrategy (the company that holds Bitcoin) from their index, had excluded Robinhood for a wile due to missing the profit requirements, and so on. It was never "meant" to cover the 500 largest companies by market cap, and has generally resisted pressure to change that.

reply
Thank you for explaining. People talk about the S&P rules like they are written in stone. There's so much emotion around these exact companies and not the structural shifts that may cause the S&P to adjust its rules. For example, for a time they banned dual class share companies, which would have banned Google from entering today (they were grandfathered on). A ban which they reversed 5ish years later.

They have resisted that pressure historically, and remained fairly conservative. But if these companies stay in the 1T+ range, that's an amount of pressure they have not had in the past. You also missed one of the largest exclusions for a time for profit reasons that's also relevant here - TSLA.

Oh! That explanation makes a lot more sense, thanks.
