My name is Matthew Schwartz and I'm the developer and sole owner of SocialSentiment.io. What started as an experiment in machine learning (ML), natural language processing (NLP), and sentiment analysis turned into the site you see here. It's a fun project to work on and I hope you find it useful.

Can social sentiment be used to predict stock price?

SocialSentiment.io grew out of an experiment. I was curious what information I could gather from sentiment analysis of tweets related to stocks. Do tweets affect stock price? Can we predict stock price movement from public sentiment on social media? Does sentiment change before, during, or after stock price swings?

Machine Learning: Staying on Topic

I started SocialSentiment.io with a somewhat simplistic machine learning algorithm. I defined a recurrent neural network to perform sentiment analysis of short texts from social media. Its purpose, and therefore its training set, is focused on the topic of stocks, companies, and their products. It returned only one floating point value representing a single prediction for each string. I quickly fell into a common ML natural language processing trap: new text which is off-topic returns unpredictable and unhelpful results. Worse yet, the results don't directly indicate the text it analyzed is off-topic.

When we started SocialSentiment.io we focused entirely on sentiment for our social media post analysis. Using thousands of real posts as training inputs to our neural networks we got back predictions as floating point numbers between 0 and 1. Each post was calculated to be leaning negative (toward 0) or positive (toward 1) by our machine learning model. We also trained with neutral posts leading to predictions around 0.5. These predictions are aggregated along with post popularity to calculate social sentiment scores for publicly traded stocks.

Love it or hate it, people are talking about the Tesla Cybertruck. Tesla kept it a well guarded secret, bringing much anticipation and speculation. Here we'll give an overview of the general public's reaction and compare that with stock price movement.

Artificial intelligence is a broad term which fundamentally refers to getting computers to emulate thinking similar to a human. While there are many categories of problems which can be addressed by AI, I have found sentiment analysis to be particularly interesting. Through training and automation, computers can monitor social media and provide insights into how people talk about companies and their products. From this analysis investors can judge public perception and decide if it has any impact on stock value.
