How do major real-world events shape online conversations?
With Anna Mancini, @giuliocimini.bsky.social @ric-dicle.bsky.social we found that while activity surges, users repeat the same ideas at an accelerating pace, limiting meaningful discussions.

Excited to share our new article published in npj Complexity with @lajello.bsky.social , @giuliocimini.bsky.social, and Laura Alessandretti, where we shed light on the dynamics behind the #GameStop short squeeze.

Exploring events (#BB #AMC #NOK) and why others were overlooked (#NIO).

TL;DR: Users boosted some stocks, ignored others.

Down the road, cool finding: there is a synergistic relationship between Reddit and trading activity (Hurst, DCCA and CCM). Two faces of the same coin (more will come)

“You got nothing. You're nothing but a lot of talk and a badge!"

We estimate the collective investment of #WSB users on #GME amounts at ~1% of the #GME market capitalization.

Social media can anticipate financial trends ✅

Here patterns of coordinated action🚀

We leverage data of social media and financial markets on an HOURLY basis (speed is the key).

Boring result? We prove that Reddit foreshadowed financial markets before the squeeze.

Not-so-boring? Effect emerged abruptly and faded away with Elon Musk tweet about #wallstreetbets

Story so far: In January 2021 financial markets were shaken by a dramatic surge in the #GME price (1600 % in 1w), largely attributed to #Reddit users.

Lots have been written (there is even a movie)...
However, when and to what extent #wallstreetbets played a role is a mystery

🚨New preprint🚨

After three years, it's time to shed light on the dynamics behind the first large-scale financial collective action driven by social media users: the #GameStop short squeeze.
