Overview

Benchmarking study demonstrates metaheuristic algorithms fail to surpass simple baselines in financial market turbulence forecasting, indicating high validation performance does not generalize.

Key Points

To determine whether nature-inspired multi-objective metaheuristics can jointly optimize feature selection, model calibration, and defensive asset allocation for short-horizon market volatility forecasting.
Evaluated 11 metaheuristics on daily SPY and VIX market data from January 2015 to February 2020 across a seven-objective optimization framework targeting rolling 80th-percentile VIX exceedances within five trading days.
Conducted 30 repeated runs per experiment and benchmarked performance against random search, nine conventional strategies, five rolling origins, and five stress definitions using Friedman tests and Holm-corrected pairwise comparisons.
While gray wolf optimization and ant colony optimization dominated validation hypervolume, holdout balanced accuracy for all metaheuristics converged between 0.66 and 0.70, failing to beat random search.
A baseline ridge-logistic model with a fixed 0.50 threshold matched or outperformed all optimized metaheuristic configurations, while ranking days solely by current VIX achieved an area under the curve of 0.772.
