Relevance
10/10
Highly relevant. The paper directly addresses the core problem of statistical arbitrage: the trade-off between the time required to statistically validate a signal and the decay of the alpha opportunity. It provides explicit formulas for the 'Alpha Survival Frontier' and the economic value of sequential testing versus fixed-time testing.
Implementation Complexity
8/10
High complexity. Requires understanding of stochastic calculus (Girsanov theorem, Brownian motion), optimal stopping theory, and information theory. Implementing the optimal stopping rules and calculating the sharp constants requires advanced numerical methods, though code is provided.
Reproducibility
5/5
The paper provides a versioned software archive on Zenodo (DOI: 10.5281/zenodo.23070742) containing numerical routines, synthetic examples, tests, and reproduction code. Installation and reproduction commands are explicitly provided.
