Dataset: Stock Market Sentiment on Social Media

During the Gamestop saga of January 2021, the WallStreetBets subreddit successfully short squeezed Gamestop’s stock, leading to a $7B loss for Melvin Capital and memes galore.

Melvin Capital vs. the little guys

Too bad Melvin didn’t have a crack ML team monitoring social media!

To help others explore social media's influence on the stock market — and avoid Melvin Capital's fate — we created a dataset of social media conversations about public stocks, labeled with sentiment.

The Stock Sentiment Analysis Dataset

The dataset contains 1000 social media discussions of publicly traded stocks, with a Positive or Negative sentiment associated with each. Some of the sentiment is unequivocal; others are much trickier for models to classify correctly, since their sentiment is masked by sarcasm and trading-specific language.

Here are some examples. Are you confident that your classifiers can label them appropriately?

For example, can your model detect the sarcasm, and realize that this message is actually Positive towards $SNOW?

Positive towards $SNOW. Can you detect the sarcasm?

How would it classify this tweet? It's overall Positive in sentiment towards Ariose Capital Management 13F, but mentions that they've exited $NVDA. Can your model parse the structure?

Negative towards $NVDA

Many off-the-shelf sentiment analysis classifiers mistakenly classify any profanity (even obscured profanity, like fack) as negative in sentiment. But profanity isn't always a bad sign!

Positive towards $GFAI

How We Labeled the Dataset

As seen from the examples above, labeling the sentiment of a message towards a particular stock can be surprisingly tricky. And often you need domain knowledge: if someone is talking about a buying a put or a short squeeze, is that positive or negative? Unless you’re familiar with these financial terms, you may not know how to label it.

Having data labelers with the right skills is essential to creating quality datasets. For this project we used a team of Surgers with financial backgrounds who are also heavy social media users, who've worked on our other financial categorization and social media data labeling projects.

Here's a peek as well at our labeling UI as well. Our platform makes it easy to create new labeling jobs, whether through our API or our WYSIWYG editor.
