Cumulative regret
Methodology: Sharpe is the annualized mean excess return divided by its standard deviation. Alpha and beta come from a covariance-based single-factor regression against the benchmark series. Suboptimality loss at each period is the best return available (including the one chosen) minus the return actually realized — so it is always ≥ 0 — and total regret is its running sum. This is a reference implementation of the general zero-instrumentation approach; see the linked paper for the full published methodology.
