本研究目的是以推論二項式選擇權評價模式為理論基礎,針對臺灣指數選擇權進行合理價位評估或預測,建立買權與賣權之買賣決策行為,並作各種模擬之本益分析供投資組合參考,以期供給學術研究及投資人作為投資理財工具的參考。 本研究以二○○三年臺灣股價加權指數,逐一作一分析,定出股價平均上昇、下跌機率及股價上昇、下跌次數機率。並以股價指數、履約價、存續期間、無風險利率作為參數估算,依據歐式買權與賣權作為模擬上之推論,美式選擇權則以假設性資料佐證之。研究結果顯示,在模擬投資效益上分析,均有獲利,短期模擬獲利百分之四,在投資上較佳;而對買權、賣權依評價後,以價位評估較佳再做投資,能減少投資風險,提高獲利率。
The purpose of this study is to develop the determinative behaviors of call and put options by evaluating the Taiwan index options. Based on the Binomial Option Pricing Model, the 2003 Taiwan stock exchange data sets were used to estimate the averages and frequencies of probabilities of rising and descending of stock price. Moreover, the stock index, strike price, time to maturity, market rate. European style options and American style options were all considered in the procedures of parametric estimation. The research found that there is a positive profit rate in the simulated investment analysis. Results of this study could provide significant findings for researchers in the related fields and the future investors.
