Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in [1].

Pseudocode Yes Algorithm 1 Orthogonal Bandit Portfolio
Open Source Code No The paper does not provide concrete access to source code for the methodology described.
Open Datasets Yes The first benchmarks are the Fama and French (FF) datasets [Fama and French, 1992]. With the raw data from the US stock market, the FF benchmarks construct the portfolios for different financial segments.
Dataset Splits No Following the rolling-horizon settings in [Shen et al., 2014], we use sliding windows with the size of τ = 120 months/weeks of training data to construct portfolios for the subsequent month/week.
Hardware Specification No The paper does not provide any specific hardware details used for running its experiments.
Software Dependencies No The paper does not provide specific ancillary software details with version numbers.
Experiment Setup Yes Following the rolling-horizon settings in [Shen et al., 2014], we use sliding windows with the size of τ = 120 months/weeks of training data to construct portfolios for the subsequent month/week. ... we set the EW portfolio as the benchmark with 1000 bootstrap resamples, 95% significance level, and a block with the size of 5.
