Dumb Money (2023)
Trader's Film Library #52 · GameStop and retail investors. The best feature film about the GameStop saga.


Original title: Dumb Money · Type: film · Created by: Craig Gillespie · Usefulness for traders: ★★★★☆
What it's about
January 2021: Keith Gill (Paul Dano), an analyst known online as Roaring Kitty, publishes his analysis of GameStop. Thousands of retail investors from a Reddit forum buy the shares and options, and the funds betting on a fall suffer huge losses.
What it has to do with markets
The film shows the mechanism of a short squeeze: when many short sellers have to buy back shares at once, the price explodes. It also shows the broker Robinhood's decision to restrict buying at the height of the euphoria.
Lessons for traders
- a short squeeze is a liquidity phenomenon, not proof of a company's value
- crowd euphoria works both ways (herding, Atlas of biases #31)
- Gill's analysis started with fundamentals and ended as a social phenomenon
- remember those who bought at the top (survivorship bias, Atlas of biases #56)
What to watch out for
The film sympathises with retail investors. Many of them lost money buying at the peak of the euphoria.
