    There are three massive mathematical assumptions to determine the “value” of the stock market:

    • The price of a stock of a company times the number of stocks of that company is the “value” of that company
    • The price of all stocks of a company is equal to the price for which a stock of the company was last traded, a simple linear extrapolation
    • The “value” of a company is measured in currency units.

    It seems clear to me that some of even all of those are in fact wrong and do not represent reality.

    In other words, the whole thing is bullshit.

    Certainly it would explain why stock markets are far more about faith and things like momentum than they are about fundamentals.

    You buy 10 copies of a specific collectible card for $5 each. Everybody is willing to pay $5 for each card you own, so you theoretically have $50 in the form of trading cards.

    But then people want that card a lot for whatever reason. They want it so much you could sell yours for $8 each. So now, without having done anything, you have $80 in the form of trading cards.

    But then people decide your cards are actually lame and don’t want to buy tgrm any more. If you were to sell them, you’d only get $1 each, so you only have $10 worth of trading cards. Thus, your cards are worth $70 less than they were, even though all the actual money is still out there and you have all the trading cards you originally bought.

    To rephrase, the value of your investment fell by $70.

    This is how stocks work. When the media reports that some money was wiped off the stock market, all the money still exists. It’s just that people decided some stocks are lame and not worth buying, which means the owners of those stocks can’t sell them for as much as they could have the previous day.

      The point you’re missing is that the loss is real for the investors holding those assets.

      If you bought ten cards for $5 each, you invested $50. When their market value rises to $80, you have an investment worth $80. If that value subsequently falls to $10, you’ve lost $70 in investment value. You can no longer sell those cards for what you could have sold them for yesterday.

      And if you were someone who bought those ten cards at $8 each, you’ve now lost $70 of your original $80 investment. That isn’t hypothetical money. That’s money you actually spent and can no longer recover by selling your cards.

      The money is not “still there”, the money transferred hands and you (or your retirement account) are holding the empty bag.

        The thing is though you haven’t actually lost money or gained money until you sell the shares and until you do sell, you still have those shares so you could always get your money back if the stock goes back up. The only time you will lose money when holding stock is if the company goes out of buisiness

          If you believe the capitalist assertion that stock always go up, sure. If you’re not close to retirement and aren’t counting on those funds anytime soon, sure.

          I believe the AI circular financing bubble isn’t meaningfully going to turn a corner and become profitable enough to pay the debts already accumulated, and once it truly pops that money will never come back to the average investor trusting the financial bros to put all their eggs into that overinflated basket.

    Money isn’t real. It’s something imaginary we agree on.

    I told my child this (about 7 yo at the time, too young probably). He said “how is it imaginary if it’s green paper?”

    Honestly that’s the best follow up.

    It is green paper. It’s just that it’s only something other than that if we agree on it’s value.

    Functionally, to the people who shorted stocks or sold while it was still high. But more accurately, it goes nowhere; the “market value” isn’t an actual number, it’s just a shorthand for “how much all the people currently playing the stock market are willing to spend on stocks.” They count up all the shares of every stock currently issued, multiply it by the amount people are willing to pay for those shares, and that’s the market value. When it goes down, that money doesn’t “go anywhere,” because it never actually existed to begin with; it was just describing how much confidence people had in the market.

    The people who short stock or who sell high are the ones who have played the game so as to benefit when that confidence drops, so they get some actual money out of the deal; but they didn’t “make” $1.8T yesterday. That’s just how much less confident investors in the American stock market are.

    Financial advisers at Chase were suggesting sitting in cash for the week of the election. Funny thing was the guy we were talking to was referring to a memo he got and didn’t even realize what the 3rd of November was this year. Or at least he pretended not to know.

    Shit might get crazy, but I’m sure the same assholes will profit no matter what.

    It never existed.

    If you make two beautiful paintings, and sell one for $1000, then decide to sell the other, but nobody wants it for more than $500, you didn’t “lose” the $500 difference.

    Maybe you even told people you had another $1000 painting, then only got $500 in cash for it, so your reported net wealth dropped by $500.

    At worst, you actually paid $1000, then sold for $500, but even then, the difference didn’t disappear, you just transferred it to the original owner by overpaying, or to the new owner by undercharging if the price goes back up.

      Indeed, if they’re talking about market capitalization then “wiped out” doesn’t make sense. It’s just simply a measure of the dollar cost of shares, much more important is liquidity and real volume.

        It only makes sense in the scenario where someone paid the $1,000 price, and then could only sell it for $500 later. They just lost $500 for their efforts.

        A lot of people though bought the other $500 painting, heard it was worth more but held on to it a bit longer to see what happens. Later they are told- no it’s still only worth $500. It’s only “opportunity cost” at that point.

        P/E ratio, price to earnings, is key to judging intrinsic wealth, although earnings can be a bit squishy of a metric. 15/1, 13/1, and thereabouts depending on sector is traditional. Tesla is trading at like 552 price to one earning. Other tech companies are also most overpriced but much of the market is also to a lesser degree.

          The market is mostly irrational, there are no ways to judge intrinsic wealth in a late stage capitalist stock market where we don’t have free markets and protectionism through tariffs.

            Idk about that, no perfect metric, but a company that earns 1 billion a year, and is likely to continue to do so, is worth about 15 billion in stock price. (edited to correct 1 to 15 from 15 to 1.)

            Obviously tech especially is out of whack. The entire market is out of whack, partly because the last two big downturns had the government bailing them out to make more than if the market didn’t crash at all.

            But the lack of enforcements of regulations or consequences, is another big factor, and there are others.

            That said, I don’t think late stage capitalism even captures where we are right now. It’s an oligarchy, a partial fascist one, a police state. Plus the government is taking stock in companies now. Intel, now this Venezuela oil deal, (a joke, they can’t get any more oil to speak of, not even in the 25 years their contract is for, that’s why the oil majors declined, but that’s another story, other than the government gets to buy at production cost, and gets like 25 percent of the company.)

            It’s oligarchic repression, sliding into authoritarianism. But my argument is admittedly just semantic and not well fleshed out perhaps.

      Who sold the stock off early? If everyone wanted to devest from a specific company and we all sold our stock at the same time and nobody wanted to buy it… huh

          Someone bargaining to buy a melon at a market can negotiate a price with the seller. Then the next buyer may negotiate a better price. You could record that the price of melons has fallen. However, all of the melons and all of the currency in the transactions is accounted for. Nothing has been lost.

        The value of a stock IS what it was previously sold for. If it sells for $100, and there are 100 shares issued, the company has a total worth of +$10,000 from stocks.

        If the stock sells for 90 bucks, then the “wealth from stocks” goes down to +9,000 total since every share is now “worth” 90 dollars.

          There don’t have to be actual sales for the price to move in an orderbook based system though, the price could collapse just from all the buy orders at the top of the range being cancelled.

          Thanks. I’m seeing two conflicting stories in my mind.

          I’d the company is worth $10,000 and there are 100 shares. And if I sold 10 for $100 each the company is still worth $10,000?

          But who gets to calculate when the value goes down? Is it when someone offers me $90 and I accept? Why can’t I just pretend to be two people and sell myself stock at $10 to artificially tank the price so I can buy the dip? Or do the reverse and pump the price up?

          Or maybe the first 10% to sell gets the best deal and the price auto-magically goes down because of ‘market trend’ and each next 10% gets increasingly screwed until the company is worthless?

            Stock markets like NYSE are supposed to prevent certain types of manipulation if detected. Wash trades (trading with yourself) is one of the generally illegal methods to move prices.

            That second example is kinda true with stock classes and new share issuance (voting shares and non voting shares, among others). It’s absolutely possible to give different types of investors more favorable terms.

            https://en.wikipedia.org/wiki/Share_class
            https://en.wikipedia.org/wiki/Stock_dilution
            https://en.wikipedia.org/wiki/Preferred_stock

            But on open stock markets, what you have is simply the order book of bids on purchases versus bids on sales. When the two don’t meet no sales happen (no volume), when a lot of people want to buy and sell you’ll see a lot of jumps up and down as sellers go down a bit to meet buyers and buyers go up a bit to meet sellers, and this represents the volume. If sellers are more eager to sell in total then they’ll push price down as a net effect, or vice versa pushing it up for buyers competing to buy.

            Current price is simply latest sale price. Total valuation is simply total shares multiplied by sale price. Yes, this isn’t accurate at all in a basic mathematical sense as it doesn’t capture nearly enough information on actual value in any sensible way.

    There are 10 Charizard Pokémon cards in existence (# of outstanding stock)

    Each card is worth $100 today, $1,000 total value

    Tomorrow the price falls to $90, $900 total value

    $100 was “wiped”

    If the charizard card is worth $80, $90, $100, or $110 will continue to play out.

    If it did the opposite and price of each card went to $110 then you could say $100 was “injected” into the market.
