Penelitian, contoh, dan desain strategi hedging saat ini

Hingga saat ini, hedging futures umumnya dirancang untuk mendeteksi perbedaan, dan jika sesuai dengan perbedaan, makan hedging tunggal. Apakah itu dapat dirancang sebagai hedging pegangan?

Pikiran Hedging

Pasar yang berbeda untuk barang yang sama atau dengan harga yang sama, peluang untuk hedging muncul ketika dua pasar memiliki perbedaan besar antara pesanan jual beli. Biasanya kita akan memakan pesanan jual beli yang memenuhi perbedaan harga dan memegang posisi hedging. Jadi tujuan hedging adalah dua, pertama untuk hedging pemegang pesanan, kedua untuk memastikan sejauh mungkin bahwa selisih pembelian dan penjualan sesuai dengan harapan kita.

Kemudian kita merancang ide perdagangan untuk menggantung order beli di pasar A, dan jual di pasar B. Kemudian kita mendeteksi order akun kita, dan transaksi yang dideteksi akan diproses selanjutnya. Misalnya, mendeteksi perubahan dalam order gantung akan segera menyeimbangkan posisi hedging di masa neraca, untuk posisi yang berlebih di saham berjangka, atau melakukan operasi perampingan.
