    摘要: 本研究提出選擇權加價利益(Mark-Up Interest)的觀點，此加價利益是選擇權賣方為彌補採取避險組合後仍可能發生的損失而向選擇權買方收取的風險補償。本研究的方法是將選擇權市價拆解成理論公平賭局價格與加價利益，建立包含加價利益、買賣權平價理論、隱含標的價格與猜測波動度的選擇權評價模型，解決隱含波動度微笑(Implied volatility smile)所帶來模型內部不一致的問題。在建立各種情境條件下之加價利益後，可用來評估選擇權市價的合理性，以提升買賣雙方對市價的合理判斷，有利於風險管理者進行選擇權之造市操作與避險。本研究經由對台指選擇權(TXO)的實證結果發現：加價利益受到距到期交易日、價況程度(Moneyness)及猜測波動度的影響。
    The standpoint of this paper is the <||>Mark-Up Interest<||> on Options. The Mark-Up Interest is regarded as the reward on the hedging portfolio to compensate for possible losses. For presenting this, Options market prices are decomposed into the Fair-game Options Prices and the Mark-Up Interests. The Options pricing model formed with the Mark-Up Interest, Put-Call Parity, Implied Underlying Price, and Guessed Volatility is used to solve the internal inconsistence caused by the Implied Volatility Smiles. Therefore, the justness of the options market prices could be estimated with the Mark-Up Interests under different scenarios. The result will help the risk manager to do market making and hedging. The empirical results based on the Options on Taiwan Stock Exchange Weighted Stock Index (TXO) in this paper are as follows: The trading days to expiry, Moneyness, and Guessed Volatility are the factors affecting the Mark-Up Interests.
