摘要: | 本篇論文提出一個在市場有漲跌幅限制下的選擇權避險策略。將利用漲跌幅限制模型中的選擇權價格封閉解去作delta動態避險,並加入vega調整項以修正其波動度的微笑曲線所帶來的避險誤差。同樣的修正也會應用在Black-Scholes模型下的避險,並以此作基準比較改善效果。研究結果顯示,以台灣市場股票為標的物的前20大交易量的選擇權,在各種價性及各種到期日,其平均絕對避險誤差及避險誤差的標準差皆有改善。尤其是短天期的選擇權,其改善效果更是顯著。 This paper implements a vega adjustment to the price limit model and examines the effect on the performance of standard delta hedging of vanilla options on the stocks of TSE. The vega adjustment has been a widely important practical application. The same adjustment to the Black-Scholes model is used as a benchmark. Our empirical findings apply to delta hedging and they are robust to varying the moneyness. |
