Report

Introduction

In mid-2021, a phenomenon occurred where failing stocks such as Gamestop, AMC, and Bed Bath and Beyond saw a dramatic demand that pushed the price of these stocks upwards. The financial markets sought an explanation, finding one from one of the most obscure places: Reddit. On the social media platform Reddit, people were discussing on the subreddit “WallStreetBets” which stocks they should hedge their bets on to make money. Using positive phrases such as “[stock prices will] rise to the moon!”, “guaranteed winner” and “buy every chance I get” propelled people to invest in these stocks, which explained the drastic fluctuation in stock prices. Furthermore, our curiosity spanned analyzing stock data from the blue-chip technology stocks Meta (formerly Facebook), Amazon, Apple, Netflix, and Google.  Inspired by the WallStreetBets phenomenon and yearning to analyze MAANG stock data, we aimed to analyze Reddit Sentiment Data to capitalize on Redditor’s sentiments for profit.

 

Approach

-Our project focused on using the subreddit with the most popular pages related to the MAANG company.
-Our methodology was to get the most amount of information relevant to what people (everyday Redditors who consume the technology the MAANG companies provide) thought of the company compared to the information relevant to MAANG stock data.

-We also used Yahoo Finance and focused on collecting data from MAANG stocks to implement a complete stock analysis.

-Once we found the data relevant to the project, we scraped the data using the YFinance API and the Python Reddit API Wrapper (PRAW).

-Included in our analysis was Wordclouds to differentiate and visualize sentiments towards the MAANG companies and the Stock Price X Vader Sentiment Model to help predict stock price changes with sentiment data.

Experiments:

Google Colab with our Data:  https://colab.research.google.com/drive/1nWm6_bOOACaBu42Me8hBpBJclUjl9lFw?usp=sharing

-Investigating Reddit, the team took the incentive to actively seek the most recently active subreddits related to each MAANG company.  

-The first step was scraping the data using the YFinance API and the Python Reddit API Wrapper (PRAW). 

-Afterward, we used the Natural Language Toolkit (NLTK) library module VADER (Valence Aware Dictionary and sEntiment Reasoner) to analyze our Reddit data.

-The two most relevant data visualizations were i) Word Cloud Visualization to Sentiments and ii) our created VADER X Stock Price Model.

-By normalizing the stock and Vader compound data, we were able to accurately analyze the relationship between sentiments and the stock price, which correlates the stock price with the trend of the sentiment.
