The members of one of Facebook’s largest groups dedicated to the stock market were buzzing about AMC and Robinhood on Friday morning. The mood is a mix of excitement and anger.

“I’m not trying to count my chickens before they hatch, but does anyone have a realistic expectation of how much they think the price of AMC shares might go up if the shorts lose out today?” one user asked. In the next post in the feed, a user complained about hedge fund managers. There’s no diamond hand emojis, no slurs, and no aggressive internet memes, all features of the r/WallStreetBets subreddit, which has been a nexus of day trader activity. On Facebook, it's just a slowly-growing community full of day traders getting increasingly angry at Wall Street.
