Trading Research

What a day! What a week! It’s been a thrilling ride and I would have paid double to be able to participate in all of this.

In fact as a side note I would have but Robinhood blocked my purchase… So I’ll definitely be leaving them as soon as this is all over.

Thank you to the amazing people at r/wallstreetbets for making it all possible.

Brass Tacks

I’ve spent the last 48 hours glued to my phone and laptop attempting to soak up as much knowledge as I can from every source possible to understand what the short squeeze is and how we can expect the next couple of weeks to go. With particular attention to exit strategies.

So far - and I’m far from done - I’ve come to these key points:

  • Hold
  • Buy
  • Don’t sell
  • Also, hold

What follows is just my raw, as-is notes. My hope is to eventually just share out sections of my Roam graph as is appropriate, but the share feature isn’t secure yet. So that’ll have to wait.

I’ll likely put together another post synthesizing this and what I continue to learn in order to try and explain what a gamma squeeze is, how this particular situation was made possible, and what else we might look for in the future as indicators of another possible short-squeeze. Although I don’t see Wall Street making this mistake again.


My notes on stock trading fundamentals. Nothing too exciting or even specific to the current GME situation yet.

    • usually traded over the counter and higher risk
  • over the counter
    • bought directly from the issuer/company
  • market order
    • an order executed at the next available price
    • can be risky if stock is wide spread (the difference between buy and sell offers is wide)
  • limit order
    • sets a maximum price to pay
    • sometimes doesn’t get filled if the market is moving fast (volatile?)
  • stop order
    • a trigger so order only executes at that price


  • understanding investments
    • trading resources (e.g. money or credit) for assets (e.g. stock or real estate)
    • basic expectation that they’ll appreciate or you’ll collect a dividend
    • risk is it could depreciate
  • what is a stock?
    • how they work
      • allow companies to raise money for operation
        • is that only at IPO?
      • shares are bought and sold on an exchange like the New York Stock Exchange (NYSE) or Nasdaq
      • in some cases they can be sold privately
        • why? how? should I care?
      • regulations on how they can be bought/sold/distributed are made by the SEC
      • can trade either common stock or preferred stock
        • example:
          If a company has 100 shares of stock outstanding, and you own 1 share, you own 1% of that company. The value of your shares will represent approximately that percentage (1%) of the company’s market capitalization, or the value of all outstanding shares.
        • why do we think it’s worth 1% of the market cap? Isn’t it only worth the dividends?
          • example: Imagine that you want to own a cupcake shop, but you only have $1,000 to start. In order to buy the necessary supplies (e.g., flour, icing, cupcake tins), you might raise money from friends and family. Let’s pretend that four of your friends each kick in $1,000, so you have $5,000 total and you’re able to get the business off the ground. In exchange for their investment, you might agree to give each of them 20% of the business and its profits. This is kind of how stocks work, except on a much larger level.
        • but do you as the cupcake business get anything when people trade your stock? seems like a great way to raise money once.

    • history of stock
      • romans created “lease holding” which was similar to stock and citizens could buy to fund public projects

        • are contracts based on fluctuation of underlying asset
    • stock, bonds, and other things are traded on the stock market
  • understanding the stock market
    • operate similar to auctions where potential buyers name their highest price (the bid) and potential sellers name their lowest price (the ask)
      • trades are executed when these overlap


This is not financial advice.
I am not a financial advisor, I’m an unemployed data engineer.
I just like the stock. :diamond: :hands:
