Available in PDF, EPUB and Kindle. Book excerpt: The London stock options market trades both European and American style options on the same underlying asset--the FT- SE 100 stock index. This paper exploits this special feature to provide direct empirical evidence on the value of early exercise in American option prices. Significant early exercise premium is found in both calls and puts. The premium is significantly higher than that predicted analytically by the binomial option valuation model. The magnitude of this premium for in-the-money options is also considerably higher than that documented for the U.S. market on the basis of an imperfect proxy. Consistent with theoretical expectations, the premium of calls increases with the degree to which the option is in the money and with the dividends on the last ex-dividend date before option maturity; and the premium for puts is positively related to the degree to which the option is in the money and to the time to maturity, and negatively related to the dividends on the last ex-dividend date prior to expiration. The early exercise premium for calls is sometimes economically significant even when there is no possibility of dividends before maturity. At the same time, the American option often trades at a discount to its European counterpart greater in magnitude than the median bid-ask spread, though this does not necessarily signal economically significant pricing inefficiency.

Available in PDF, EPUB and Kindle. Book excerpt: This study estimates the value of the early exercise premium in American put option prices using Swedish equity options data. The value of the premium is found as the deviation of the American put price from European put-call parity, and in addition a theoretical estimate of the premium is computed. The empirically found premium is also used in a modified version of the control variate approach to value American puts. The results indicate a substantial value of the early exercise premium, where the premium derived from put-call parity is higher than the theoretical premium. The premium also increases with moneyness and time left to expiration, while the effect of interest rate and volatility depends on the moneyness of the option. The modified control variate technique works reasonably well relative the theoretical models. In particular, for deep in-the-money options, this technique is superior.

This book was released on 2014-10-14 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The early exercise opportunity of an American option makes it challenging to price and an array of approaches have been proposed in the vast literature on this topic. In The Numerical Solution of the American Option Pricing Problem, Carl Chiarella, Boda Kang and Gunter Meyer focus on two numerical approaches that have proved useful for finding all prices, hedge ratios and early exercise boundaries of an American option. One is a finite difference approach which is based on the numerical solution of the partial differential equations with the free boundary problem arising in American option pricing, including the method of lines, the component wise splitting and the finite difference with PSOR. The other approach is the integral transform approach which includes Fourier or Fourier Cosine transforms. Written in a concise and systematic manner, Chiarella, Kang and Meyer explain and demonstrate the advantages and limitations of each of them based on their and their co-workers'' experiences with these approaches over the years.

Download or read book Hints for an Extension of the Early Exercise Premium Formula for American Options written by Hans-Peter Bermin and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The characterization of the American put option price is still an open issue. From the beginning of the nineties there exists a non-closed formula for this price but nontrivial numerical computations are required to solve it. Strong efforts have been made to propose computational efficient methods but few of them have strong mathematical reasoning to ascertain why these methods work well and how important it is to consider a good approximation to the boundary or to the smooth pasting condition. We present an extension of the American put price aiming to catch weaknesses of the numerical methods given in the literature.

Download or read book European Put Call Parity and the Early Exercise Premium for American Currency Options written by Geoffrey Poitras and published by . This book was released on 2016 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European put-call parity condition is used to estimate the early exercise premium for American currency options traded on the Philadelphia Stock Exchange. Using a sample of 331 pairs of call and put options with the same exercise price and time to expiration, evidence is provided for early exercise premiums that average 5.03% for put options and 4.60% for call options. The premiums for both call and put options are strongly related to the interest rate differential and time to expiration. These results have implications for the use of European option pricing models in the valuation of American options.

Available in PDF, EPUB and Kindle. Book excerpt: This paper examines empirically the value of early exercise by testing the ability of two American put valuation models to predict the early exercise premium for the Samp;P 100 American put options. An accuracy test and a quality test are performed on (1) the MacMillan (1986) amp; Barone-Adesi and Whaley (1987) model, and (2) the Carr, Jarrow and Myneni(1992) model. The test results show that early exercise premium is significant regardless of moneyness. Moreover, consistent with the theory, the value of early exercise is significantly negatively related to moneyness and interest rates and significantly positively related to time to maturity and to the volatility of the underlying index. Both American put valuation models examined do not fully capture the value of early exercise embedded in American put prices.

Download or read book Probabilities and Values of Early Exercise written by James N. Bodurtha and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This article analyzes fundamental differences between American spot and futures options. These options differ in their early exercise probabilities and values, and in option buyers' exercise behavior. We find two key results: one theoretical and one empirical. First, unlike spot options, some futures options' early exercise probabilities and values do not correspond. Specifically, increased volatility raises the early exercise premium for in-the-money futures calls, but lowers the associated early exercise probability. Similarly, increasing the domestic interest rate raises the futures put early exercise premium, while lowering the associated early exercise probability. Second, observed early exercise experience of Philadelphia Stock Exchange spot options and Chicago Mercantile Exchange futures options is consistent with optimal early exercise behavior prescribed by a standard American option pricing model. Both types of option exercise events occur at or near the modeled early exercise boundaries.

Download or read book Valuation of Early Exercise Premium on Currency Options written by John Lee and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies on American options have shown that European style models do not reflect early exercise premium (EEP). This project expands on the Poitras, Veld and Zabolotnyuk (2006) paper which applies the put-call parity method to currency options data from American options traded at PHLX for EEP. We define a wider range for in-the moneyness and use a rolling volatility for the volatility parameter. We estimate the early exercise premium as a percentage of option price (REEP) for calls and puts to be 7.329%, 6.122%, respectively. We then regress the REEP against moneyness, interest differentials, and time to maturity and volatility. Our results show that REEP is strongly and positively correlated with interest rate differentials and time to maturity. The effect of moneyness is less apparent. The effect of volatility on REEPs of put options is significantly negative, which coincides with the results of Poitras, Veld and Zabolotnyuk (2006).
