台指選擇權短天期契約價差交易績效之探討

本文檢驗台灣期交所於 2012 年11 月14 日推出的週選擇權契約後，選擇權交易量是否會有顯著的影響。進一步探討買進買權、買進賣權、賣出買權、賣出賣權、買權空頭價差、賣權多頭價差、買權多頭價差與賣權空頭價差八種交易策略之最佳運用時機及操作績效。實證結果發現，週選擇權短天期契約推出後，選擇權交易口數顯著的成長，但選擇權總交易量並不顯著。運用八種策略績效實證後發現以賣出賣權策略的績效最穩定，不論從價外四檔至價內四檔各績效都有一定的正成長，其中價平賣權報酬率最高。其他週選擇權交易策略績效並不穩定。期交所推出短天期契約後已使得結算行為變得更為頻繁更為常態，對以往引人垢病的外資操控結算行情的情況應可改善，也讓期貨交易更為自由化、合理化，公平化，進而提升國際競爭力。
