Simple tool for analyzing the movements of stock prices around earnings dates for several companies.
This is similar to other offerings from marketchameleon.com or optionslam.com except you don't have to create an account or pay for access to this tool. There is nothing magic here, just rounding up all the historical data for the tickers and seeing how they move in response to earnings.
npm install
npm start
Then browse to http://localhost:8080
You can add a new ticker from the website itself!
