    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.

      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.

      Congratulations, you just figured out market manipulation! Some of that isn’t strictly legal, but since when does that affect people’s actions?
