Setiap perusahaan yang menggunakan valuta asing dalam kegiatan operasionalnya akan terkena dampak foreign exchange exposure. Resiko ini dapat dikelola dengan menggunakan lindung nilai (hedging). Namun dalam melakukan hedging, tidak selamanya perusahaan dapat meminimalkan kerugian atau memaksimalkan keuntungan. Disinilah teknik peramalan berperan agar perusahaan dapat mengambil keputusan kapan harus melakukan hedging. Teknik yang dimaksud adalah autoregressive integrated moving average (ARIMA). Peramalan menggunakan jumlah sampel data kecil menghasilkan mean forecast error terendah dibandingkan jumlah sampel data besar. Perbandingan kebijakan hedging menggunakan forward contract menunjukkan bahwa hasil peramalan ARIMA dapat dijadikan dasar pengambilan keputusan dalam memaksimalkan cash flows perusahaan.

This is where the forecasting technique needed so the company may know when to do hedging. The technique is autoregressive integrated moving average (ARIMA). Smaller sample data amount will generate lower mean forecast error compare to use bigger sample data. Hedging policy comparison using forward contract shows that ARIMA forecast results could be used for decision making to maximize company's cash flows.
