Several Key PerformanceAnalytics Functions From R Now In Python [QuantStrat TradeR]

So, thanks to my former boss, and head of direct indexing at BNY Mellon, Vijay Vaidyanathan, and his Coursera course, along with the usual assistance from chatGPT (I officially see it as a pseudo programming language), I have some more software for the Python community now released to my github.

Community fav QuantStrat TradeR back posting after almost 2 year hiatus: This function VITAL for portfolio backtesting is now in Python [QuantStrat TradeR]

So, it’s been a little while. But after a couple of years of some grunt work analytics jobs *and* consulting for a $1B AUM fund, I’ve decided that I had a bit more in the tank to share as far as quant content creation–quantent creation (?)–goes. And a function I’ve searched for in Python

Two Different Methods to Apply Some Corey Hoffstein Analysis to your TAA [QuantStrat TradeR]

A Python Investigation of a New Proposed Short Vol ETF - SVIX [QuantStrat TradeR]

This post will be about analyzing SVIX–a proposed new short vol ETF that aims to offer the same short vol exposure as XIV used to–without the downside of, well, blowing up in 20 minutes due to positive feedback loops. As I’m currently enrolled in a Python bootcamp, this was one of my capstone

How You Measure Months Matters — A Lot. A Look At Two Implementations of KDA [QuantStrat TradeR]
