A study comparing an econometric model, ARMA-GARCH, against a deep-learning model, LSTM, for forecasting the Swedish small-cap index OMXSSC — then testing each as an algorithmic trading strategy.
The headline result: ARMA-GARCH beat LSTM on both accuracy and returns, and only ARMA-GARCH produced a strategy that outperformed the index over the study period. A win for classical statistics over the hyped model.
