Kali ini, strategi yang dibawa oleh FMZ Quant adalahPerlindungan Delta Dinamik Pilihan Deribit, disingkat sebagai DDH.
Model harga opsyen; model B-S; harga opsyen ditentukan berdasarkan
Eksposur risiko opsyen:
Penjelasan Prinsip DDH Dengan menyeimbangkan delta opsyen dan niaga hadapan, netraliti risiko arah perdagangan dicapai. Selepas memegang kedudukan kontrak opsyen dan menggunakan niaga hadapan untuk lindung nilai dan menyeimbangkan Delta, apabila perubahan harga asas, keseluruhan Delta akan muncul tidak seimbang lagi.
Contohnya: Apabila kita membeli pilihan panggilan, kita mempunyai kedudukan bullish. pada masa ini, adalah perlu untuk masa hadapan pendek untuk lindung nilai pilihan Delta untuk mencapai netraliti keseluruhan Delta (0 atau dekat dengan 0). Mari kita abaikan faktor-faktor, seperti hari-hari sehingga tamat tempoh dan turun naik tersirat kontrak opsyen. Skenario 1: Apabila harga asas meningkat, pilihan Delta meningkat, dan keseluruhan Delta bergerak ke nombor positif. Masa hadapan diperlukan untuk lindung nilai lagi, dan beberapa kedudukan pendek dibuka untuk meneruskan masa hadapan pendek, sehingga keseluruhan Delta seimbang lagi. (Sebelum menyeimbangkan semula, delta opsyen adalah besar, delta niaga hadapan agak kecil, keuntungan marginal opsyen beli melebihi kerugian marginal kontrak pendek, dan keseluruhan portfolio akan menghasilkan keuntungan.) Skenario 2: Apabila harga asas jatuh, delta opsyen menurun, dan keseluruhan delta bergerak ke nombor negatif, dan beberapa kedudukan niaga hadapan pendek ditutup untuk membuat baki delta keseluruhan lagi. (Sebelum menyeimbangkan semula, delta opsyen adalah kecil, delta niaga hadapan agak besar, kerugian marginal opsyen panggilan adalah kurang daripada keuntungan marginal kontrak pendek, dan keseluruhan portfolio masih akan mempunyai keuntungan.)
Oleh itu, secara ideal, kenaikan dan kejatuhan asas kedua-duanya membawa keuntungan, selagi pasaran turun naik.
Walau bagaimanapun, terdapat faktor lain yang perlu dipertimbangkan: nilai masa, kos perdagangan dan lain-lain.
Jadi, saya memetik penjelasan seorang guru dari Zhihu:
Fokus Gamma Scalping bukan delta, lindung nilai delta dinamik hanyalah cara untuk mengelakkan risiko harga yang mendasari dalam proses. Gamma Scalping memberi tumpuan kepada Alpha. Alpha bukan Alpha pemilihan saham. Di sini, Alpha = Gamma / Theta, iaitu berapa banyak Gamma ditukar dengan kemerosotan masa unit Theta. Itulah intinya. Adalah mungkin untuk membina gabungan kenaikan dan kejatuhan dengan keuntungan terapung, pasti disertai dengan kemerosotan masa, dan masalahnya adalah nisbah prestasi kos.
