This is a small collection of research papers on long-term investing. They are written as Python Notebooks so they can be easily modified and run again.
There is a YouTube video for each research paper.
- Forecasting Long-Term Stock Returns (Notebook) (Google Colab)
- Comparing Stock Indices (Notebook) (Google Colab)
The Python Notebooks use source-code located in different files to allow for easy re-use across multiple Notebooks. It is therefore recommended that you download the whole repository from GitHub, instead of just downloading the individual Python Notebooks.
The easiest way to download and install this is by using git from the command-line:
git clone https://github.com/Hvass-Labs/FinanceOps.git
This creates the directory FinanceOps and downloads all the files to it.
This also makes it easy to update the files, simply by executing this command inside that directory:
git pull
You can also download the contents of the GitHub repository as a Zip-file and extract it manually.
If you want to edit and run the Notebooks on your own computer, then it is
suggested that you use the Anaconda
distribution of Python 3.6 (or later) because it has all the required packages
already installed. Once you have installed Anaconda, you run the following
command from the FinanceOps directory to view and edit the Notebooks:
jupyter notebook
If you want to edit the other source-code then you may use the free version of PyCharm.
If you do not want to install anything on your own computer, then the Notebooks can be viewed, edited and run entirely on the internet by using Google Colab. You can click the "Google Colab"-link next to the research papers listed above. You can view the Notebook on Colab but in order to run it you need to login using your Google account. Then you need to execute the following commands at the top of the Notebook, which clones FinanceOps to your work-directory on Colab.
import os
work_dir = "/content/FinanceOps/"
if os.getcwd() != work_dir:
!git clone https://github.com/Hvass-Labs/FinanceOps.git
os.chdir(work_dir)
