Part 1 of 2 — the intuition. Part 2 covers the methodological remedies. Every systematic researcher has lived this moment. The baseline equity curve is decent but unexciting: Sharpe 0.8, a few uncomfortable drawdowns. Then the idea arrives. What if I filtered out entries when volatility is too high? You add the filter, rerun the […]

The example track record is synthetic and fully specified, so every number is reproducible; Search for “Monte Carlo simulation trading strategy” and you will find, with remarkable consistency, the same recipe: take the list of […]
In the quantitative analysis of financial markets, the leap from univariate to multivariate time series analysis is not just a statistical exercise — it is a necessity dictated by the inherently interconnected nature of global markets. In this article I revisit and expand my Module 6 project for the Certificate in Quantitative Finance (CQF). We […]

Luigi Piva — ALGOSWORKSAI LTD This is the complete, honest account of a week of testing on a simple question: can you use a statistical measure of market stress to improve an equity portfolio, exiting into turbulence and re-entering into calm? The short answer is “yes, but.” The long answer — with the dead ends, […]
Luigi Piva — ALGOSWORKSAI LTD This article is the complete, technical version of an idea I introduced elsewhere: how to measure market stress with the Mahalanobis distance, how to implement it in Python without fooling yourself, and what to expect when you use it. It contains working code and the methodological discipline that separates a […]
