Every quant has been there. You’re backtesting a strategy, the overall results look good, but something feels off when you dig into the day-by-day breakdown.

If you’re not famliar with Option Alpha, and are serious about trading options, I highly recommend you check them...
This is my implementation of the Reweighted Price Relative Tracking strategy documented in the research paper by Zhao-Rong Lai et al. Shout out to the “Paper-to-Profit” substack for calling my attention to it. The code is not meant to be deployed as-is but serves as an educational template for those interested in modern portfolio optimization techniques based on academic research...
This is a factor optimization strategy, written for Quantconnect LEAN (Python). The attached code demonstrates how to combine technical and fundamental factors in an optimized portfolio, focusing on the most heavily-weighted stocks in SPY. Feel free to re-use this, customize it, make it better and re-share. General Architecture The strategy uses a two-factor model combining...
This is my take on scheduled intraday universe selection, written in Python (LEAN). The attached code is not a tradable strategy, it’s a template for others to use in building their own strategies. Feel free to re-use this, customize it, make it better and re-share. General ArchitectureThere are three universe selection phases: Coarse, Fine and Intraday (scheduled). In the Fine and...

Last night I wasn’t up for a challenge, but I still wanted the...
