This year's activity coincided with a surge of rookie investors who joined the world of stock trading to ride the historic market rebound. Remote work, stimulus checksandhigher personal savings levels,as well as social media chatrooms only accelerated the boom in retail trading.
The meme stock saga started just days into 2021 when retail traders teamed up on Reddit's WallStreetBets' forum, aiming to bid up $GameStop(GME.US)$'s shares, which were heavily shorted by hedge funds. The retail buying triggered massive short covering among hedge funds that fueled the rally even further.
Trading volume for GameStop and meme stock favorite $AMC Entertainment(AMC.US)$ has faded. About 2.5 million shares of GameStop are changing hands daily based on a 30-day average as of Dec. 22, a fifth of that in January.

Reddit traders also appear less focused on GameStop and AMC, which were the two most-mentioned tickers on WallStreetBets this year.

WallStreetBets mentions for both peaked on Jan. 28 at about 267,000 for GameStop and 47,000 for AMC, but typical days for each over the past few months see hundreds, not thousands, of mentions.
