    TLDR The method accurately predicted stock price changes, showing most companies' returns decreased due to BDS actions.
    The study applied the non-seasonal Holt-Winters method to forecast stock price returns of six companies affected by the Boycott, Divestment, and Sanctions (BDS) action. The method yielded accurate results, with a MAPE value of less than 10%. The study found that almost all companies experienced a decrease in stock price returns, except for PT Map Boga Adiperkasa Tbk, which saw an increase. This indicates that BDS actions have a significant impact on these companies. The method is effective for short-term forecasting and can handle data limitations while providing reliable results.
