This project is meant to be an example of how to organize a data analytics case study/project. It is not meant to provide insights for stock data or stock trading. It also does not build on any finance literature (e.g. regarding risk factors such as size, growth, or momentum).
The returns generated may also be different from the returns of, say, the S&P 500 index, as the universe of stocks/data used may be biased (e.g. survivorship bias).
