We continue the series by replicating using as much data and code as provided in the source material. We create a three-state Gaussian Mixture Model and fit it so S&P500 data. I examine the output and give feedback about my coding replication and data sourcing along the way. Then I try to apply a proxy for adding economic data as a feature—previous posts Part 1 and Part 2.
I was continuing from the last post. I will explain why I picked the paper I did, answer the questions from the previous post, and show my note-taking and thought process. After reading hundreds if not thousands of whitepapers, blogs, or articles, this is my distilled version of how I approach it. I will document this for the first time. It may be different from how others approach it. Over time you will get your own approach. So let’s hit the stacks.
The internet is teeming with resources for potential alpha. How do you separate the wheat from the chaff? In this series of blog posts, I will explain my process for identifying sources worth diving deeper into and extracting some kind of benefit to a portfolio or strategy. This will be a side-by-side view of my workflow as an individual. As of now, I have no idea what even to research or how I will go about doing it. So let us begin.
