- Abstract
- This research aims to examine how much impact social media channels have on stock returns during unusual market events.

The sentiment is derived utilizing two financial dictionary analysis, VADER, a sentiment analysis tool designed specifically for social media, as well as our own constructed dictionary EMOJI, which is created to better analyze the emotions expressed on WSB. We collect the sentiment using Python, a high-level programming language, and empirically examine WSB effective predicting power on individual stock returns using a panel data regression. We come to the conclusion that we do not have enough significant values to draw any conclusions about how WSB influences the stock return. We, on the other hand, are capable of determining that our strategies of extracting the sentiment work differently, where EMOJI appears to be better at capturing the mood on WSB. We believe this strengthens our preconceptions about the tone on WSB and leave it for further research to proceed upon this. (Less)
