Strategi yang dibawa FMZ Quant adalah strategi Deribit Options Delta Dynamic Hedging, atau pendeknya DDH (Dynamic Delta Hedging).
· Model penetapan harga opsyen, model B-S, harga opsyen ditentukan berdasarkan [harga subjek], [harga kuasa], [masa yang tersisa hingga tamat tempoh], [vokaliti tersirat], dan [ kadar bebas risiko].
· Eksposur opsyen:
-Delta
· Penjelasan prinsip DDH Arahan perdagangan yang netral risiko dicapai dengan menyamakan Delta opsyen dan niaga hadapan. Selepas mengambil kedudukan dalam kontrak opsyen dan menyeimbangkan Delta dengan lindung nilai niaga hadapan, keseluruhan Delta akan menjadi tidak seimbang lagi apabila harga subjek bergerak. Gabungan pilihan dan kedudukan niaga hadapan sedemikian memerlukan lindung nilai dinamik berterusan untuk menyamakan Delta.
· Sebagai contoh: Apabila kita membeli pilihan panggilan, kita memegang kedudukan dalam arah panjang pada ketika ini. Pada masa ini, adalah perlu untuk pergi pendek niaga hadapan untuk lindung nilai Delta pilihan, mencapai keseluruhan Delta neutral (0 atau dekat dengan 0). Mari kita abaikan masa yang tersisa untuk tamat tempoh kontrak opsyen, turun naik dan faktor lain. Skenario 1: Apabila harga subjek naik, Delta pilihan meningkat, dan keseluruhan Delta bergerak ke nombor positif, dan niaga hadapan perlu lindung nilai lagi. (Sebelum menyeimbangkan semula, Delta opsyen adalah besar, manakala masa hadapan adalah agak kecil. Keuntungan marginal opsyen panggilan melebihi kerugian marginal kedudukan kontrak pendek, dan keseluruhan portfolio akan menghasilkan.)
Skenario 2: Apabila harga subjek jatuh, bahagian opsyen Delta menurun dan keseluruhan Delta bergerak ke nombor negatif, menutup sebahagian daripada kedudukan niaga hadapan pendek dan membawa keseluruhan Delta ke keseimbangan semula. (Sebelum menyeimbangkan semula, pada masa ini, Delta opsyen adalah kecil, manakala masa hadapan adalah agak besar. Kerugian marginal opsyen panggilan adalah kurang daripada keuntungan marginal jawatan kontrak pendek, dan keseluruhan portfolio masih akan menghasilkan keuntungan.)
Oleh itu, dalam keadaan ideal, peningkatan dan penurunan subjek akan membawa manfaat selagi pasaran turun naik.
Walau bagaimanapun, terdapat juga faktor yang perlu dipertimbangkan: nilai masa, kos transaksi, dan faktor lain.
Oleh itu, penjelasan hotshot di Zhihu dipetik:
The focus of Gamma Scalping is not on delta, dynamic delta hedging is just a way to avoid underlying price risk in the process.
Gamma Scaling focuses on alpha, which is not the alpha of stock selection. Here, alpha=gamma/theta, that is, how much gamma is exchanged for the time loss of unit Theta.
This is the point of concern. It is possible to construct a portfolio that floats both up and down, but it must be accompanied by time loss, and then the problem lies in the cost effectiveness.
