What is WallStreetBets (WSB)?

WallStreetBets (WSB) or r/wallstreetbets is a subreddit that is part of the Reddit online forum where users discuss stock and options trading strategies. WSB has become notable because of its tendencies toward aggressive trading strategies and profane language, not to mention its role in the Gamestop short squeeze, which resulted in substantial losses on short positions from U.S. firms. These losses topped $70 billion USD in a relatively short period of time in early 2021.
