Topic: Interesting Readings

Today I spent some time challenging our workflow, and one of the layers we usually go through is the academic, specialist, and institutional best-practice layer.

Here, for good readers only :-) — meaning time and patience required — are some interesting readings in the context of trading strategy selection, statistical relevance, correlations, and a few other related topics.

They might be interesting for anyone who likes to look beyond single backtests and think more deeply about how trading strategies should be evaluated.

The Adaptive Markets Hypothesis (Andrew Lo).
https://www.researchgate.net/publicatio … erspective

Concept: Explains why trading edges are perishable. It justifies our high-turnover replacement model and the 3-month median lifespan of promoted strategies.

• ...and the Cross-Section of Expected Returns (Harvey, Liu, & Zhu).
https://www.researchgate.net/publicatio … ed_Returns

Concept: Addresses the "Data Mining" problem. It supports our 6-KPI "Filter Stack" as a necessary barrier against the thousands of "lucky" backtests generated by automated tools.

The Deflated Sharpe Ratio (Marcos López de Prado)
https://www.researchgate.net/publicatio … -Normality

Concept: Corrects for "Selection Bias." It validates our rigorous incubation process before capital allocation.

Does Academic Research Destroy Predictability? (McLean & Pontiff)
https://www.semanticscholar.org/paper/2 … d0a2582415

Concept: Proves that alpha decays post-discovery. This supports our "Strict Thresholds" policy—treating mature strategies with the same skepticism as new ones.

Portfolio Selection (Harry Markowitz)
https://www.researchgate.net/publicatio … _Selection

Concept: The mathematical root of our 0.80 Correlation Cap. It proves that portfolio risk is driven more by the link between strategies than by individual performance.

Honey, I Shrunk the Covariance Matrix (Ledoit & Wolf)
https://www.researchgate.net/publicatio … _Selection

Concept: Addresses the instability of live correlations. It is the theoretical backbone for our dynamic monitoring of "Regime Lock" in the Master accounts.

Stepwise Multiple Testing (Romano & Wolf)
https://ideas.repec.org/p/bge/wpaper/17.html

Concept: (Stable Institutional Mirror) Supports our Hysteresis Loops (PwL/OgI) by proving that consistent performance across multiple stages is the only reliable signal of a lasting edge.

Sequential Analysis (Abraham Wald)
https://projecteuclid.org/journals/anna … 30491.full

Concept: (Project Euclid Stable Link) Validates our rule by providing a framework for making continuous "Keep/Prune" decisions as new data arrives.

The 7 Sins of Quantitative Investing (López de Prado)
https://portfoliooptimizationbook.com/b … -sins.html

Concept: A roadmap for avoiding common pitfalls like survivorship and look-ahead bias, supporting our "Lifetime String" data fusion.

Crowded Trades and Tail Risk (Pedersen & Stein)
https://www.researchgate.net/publicatio … _Tail_Risk

Concept: Discusses how crowded strategies lead to liquidity holes. It justifies our 10% Global Kill-Switch as a safeguard against systemic events.
