american lookback option

Journal of International Money … Lookback option is a well-known path-dependent option where its payoff depends on the historical extremum prices. The mathematical technique of analyzing the exercise boundary curves of lookback options at infinitesimally small asset value is also applied to a similar analysis in the American two-asset minimum-put option model. By the asymptotic analysis introduced in Fouque et al. ²pA{>* An option that allows the buyer to choose as the option strike price any price of the underlying asset that has occurred during the life of the option. Lookback Option. KEYWORDS: United States North America District of Columbia Virginia INDUSTRY KEYWORDS: LookBack Options, also known as Hindsight Options or Mocatta Options, are exotic options which allows the holder to "Look Back" at the price action of the underlying asset during expiration to decide the optimal price at which to exercise the Lookbacks Options. To compute the value of a floating-strike lookback option, Strike must be specified as NaN . Using the similar techniques, the optimal exercise boundary can be given by the following corollary. In this paper, we study the lookback option of the American style suggested in Dai (Journal of Computational Finance 4(2):63–68, 2000), and Dai and Kwok (SIAM Journal on Applied Mathematics 66(1):206–227, 2005) under stochastic volatility. Our approach is more efficient than the tree methods because recalculating the option prices is much quicker. This option will always be … An option contract where the holder is permitted to choose the strike price. A number of researchers have suggested an interesting and instructive approach to valuing lookback options.2Consider an American-style lookback put. We study a default problem with the bankruptcy time being defined as the first passage time of the underlying asset price. Fixed Strike. Lookback Call Option A call option giving the holder the right (but not the obligation) to buy the underlying asset on or by the expiration date at its lowest price that occurred between the start of the option and the time it is exercised. To compute the value of a floating-strike lookback option, Strike must be specified as NaN. The initial stock price is 50, the stock price volatility is 40%, the risk-free interest rate is 10% and the life of the option is 3 months. An “American” option can be exercised in any day before a specified date in the future. Lookback option. We examine the early exercise policies of the floating strike and fixed strike American lookback options, while the realized extrmum of the asset price can be monitored continuously or discretely, The characterizations of the optimal exercise prices of American lookback options are also discussed. That is, the buyer of a lookback call may choose a low strike price and the buyer of a lookback put may choose a high one. options monte-carlo derivatives option-pricing quantitative-finance american-options jump-diffusion stochastic-volatility-models black-scholes fourier-transform sabr european-options levy-processes heston-model asian-option bermudan-option swing-option lookback-option variance-swap barrier-option (2001). I get a call option price as minus 4.24$ i.e a negative number , any explanations please. texts, e.g. Applying the quadratic approximation, we obtain the following general form for the approximate solution of American lookback rate call option: (3.10) C 1 b (t, S, S min) = c 1 b (t, S, S min) + A 1 S min (S S min) γ 1 + A 2 S min (S S min) γ 2, where γ 1 and γ 2 are given by .
