Grid search, random search, or Bayesian optimization are applied until the “best” set of hyperparameters is found. But in financial ML, this approach is dangerous. Financial data is noisy, non-stationary, and limited. Aggressive hyperparameter tuning amplifies overfitting, tailoring the model too closely to historical quirks that won’t repeat. The result: strat
