價格限制下--認購權證價格衡量之分析

廖國佑 Unknown Date (has links)
本篇論文主要是探討一個受到價格限制之下認股權證的價值。由於台灣股市有每天百分之七的價格限制,且認權證將於今年年中開放交易。而就筆者所知,目前尚無文獻探討一個當標的物受到特殊的價格限制時,認購權證公式解評價的問題。故本文嘗試利用蒙地卡羅模擬來估算此種特殊的認購權證價值。本文發現,模擬值將大於事後標準差所得到的Black-Scholes模型值。所以若以過去觀察股價來估算報酬標準差求算傳統Black-Scholes模型值,將使得認購權證的價值偏低。

白銀期貨的價格限制-以馬可夫鏈蒙地卡羅方法分析 / price limits in the silver futures market: a MCMC approach

鄭仲均 Unknown Date (has links)
在這篇論文中,我們運用馬可夫鏈蒙地卡羅(MCMC)方法來估計沒有價格限制下的白銀期貨價格。接著我們採用FIGARCH模型來計算VaR值,以進而評估估計成果。在本文中我們分別對三種不同分配下的FIGARCH模型計算VaR值,而實證結果顯示出在沒有價格限制下,白銀期貨有較好的估計結果。 / In this paper, we try to implement the MCMC method to simulate the price of the silver futures without price limits. Then we compute the VaR by using the FIGARCH model because of the long memory properties in our data. There are three distributions we use to estimate model and compute VaR. The empirical results show that the silver futures without price limits performs better in computing in-sample VaR.
