FMZ Quantが提案する戦略は Deribit Options Delta Dynamic Hedging (短くDDH (ダイナミック・デルタ・ヘッジ) 戦略) です.
· オプション価格設定モデル,BSモデル オプション価格は [対象価格], [パワー・ワイド価格], [有効期限まで残る時間], [暗黙の波動性],および [リスクフリーレート]に基づいて決定されます.
■ オプションの露出額:
-デルタ
■ DDH 原則の説明 リスクニュートラルな取引方向は,オプションと先物Deltaをマッチすることによって達成される.オプションのDeltaが対象価格の変化に従うため,先物Deltaは変化しない. オプション契約にポジションを設定し,デルタを先物保証でバランスすると,対象物価格の変動に伴い,全体的なデルタは再び不均衡になる.そのようなオプションと先物保証の組み合わせは,デルタを均衡させるために継続的なダイナミックヘッジを必要とします.
■ 例えば: コールオプションを購入すると,この時点で長方向のポジションを保持します.この時点で,オプションのデルタをヘッジするために先物をショートする必要があります. オプション契約の期限まで残った時間,変動等を無視しましょう. シナリオ1: 価格が上昇すると,オプションのデルタが増加し,全体的なデルタは正数に移動し,先物はまたヘッジする必要があります.先物を引き続き短縮するためにいくつかのショートポジションを開いて,全体的なデルタが再びバランスになります. (再バランス前には,オプションのデルタは大きいが,先物取引は比較的小さい.コールオプションの限界利益は,契約ショートポジションの限界損失を上回り,ポートフォリオ全体が収益を上げます.)
シナリオ2: 対象物の価格が下がると,デルタのオプション部分は減少し,全体的なデルタはマイナス数値に移動し,ショートフューチャーポジションの一部を閉鎖し,全体的なデルタを再びバランスにします. (再バランス前,この時点でオプションのデルタは小さいが先物では比較的大きい.コールオプションの限界損失は契約ショートポジションの限界利益よりも小さい.そして,ポートフォリオ全体はまだ利益をもたらすだろう.)
したがって,理想的な状態では,市場が変動する限り,対象物の増加と減少が利益をもたらすでしょう.
しかし,考慮すべき要因もあります. 時間価値,取引コスト,その他.
Zhihuのトップの説明はこう引用されています:
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.
