  text: In January 2021, the GameStop stock was the epicenter of the first case of
    predatory trading initiated by retail investors. We use brokerage accounts to
    study who participated in this GameStop frenzy and how they performed. We investigate
    the extent to which investors’ personal and trading characteristics differ from
    the general population of retail investors. GameStop traders had a history of
    investing in speculative instruments, including stocks with lottery-like features.
    They were also more likely to close their positions before the peak of the bubble.
    At the onset of the frenzy, numerous retail investors also shorted GameStop. Overall,
    our results indicate that the GameStop frenzy was not a pure digital protest against
    Wall Street but speculative trading by a group of retail investors, in line with
    their prior high-risk trading behavior.

  text: In early 2021, the finance world was taken by storm by the dramatic price
    surge of the GameStop Corp. stock. This rise is being, at least in part, attributed
    to a group of Redditors belonging to the now-famous r/wallstreetbets (WSB) subreddit
    group. In this work, we set out to address if user activity on the WSB subreddit
    is associated with the trading volume of the GME stock. Leveraging a unique dataset
    containing more than 4.9 million WSB posts and comments, we assert that user activity
    is associated with the trading volume of the GameStop stock. We further show that
    posts have a significantly higher predictive power than comments and are especially
    helpful for predicting unusually high trading volume. Lastly, as recent events
    have shown, we believe that these findings have implications for retail and institutional
    investors, trading platforms, and policymakers, as these can have disruptive potential.
