The more an asset price swings around from day to day, the more volatile the asset is said.
The answer is research.If the possibility of that something can be foreseen, probability arbitrage is possible.For example expiration dates are currently 12/17/2010 for Friday and saturday when all is settled is 12/18/2010.Black, Merton and Scholes: Their work and its consequences.The Pricing of Options and Corporate Liabilities.In this particular example, the strike price is set to unity.From reading your site, which is fantastic by the way, it seems that this "pricing" tunisia-sat dreambox player and web streamer 6.0.0 beta strategy is mainly used for Euro style options.Although with significant algebra; see, for example, Hong-Yi Chen, Cheng-Few Lee and Weikang Shih (2010).It works fine for.Chicago Board Options Exchange and other options markets around the world.R displaystyle r, the annualized risk-free interest rate, continuously compounded (the force of interest ).The further OTM the option is, the sooner it will have zero value when altering.If one uses spot S instead of forward F, in d displaystyle d_pm instead of the 1 2 2 displaystyle frac 12sigma 2 term there is ( r 1 2 2 ), displaystyle left(rpm frac 12sigma 2right)tau, which can be interpreted as a drift factor."An Equation and its Worlds: Bricolage, Exemplars, Disunity and Performativity in Financial Economics".Also, dividends are indeed incorporated into the Black and Scholes model and form part of the Theoretical Forward price.5 MacKenzie, Donald (2006).Therefore the Black Scholes Model first calculates what the Theoretical Forward price would be at the expiration date.Is this what you are referring to?This is because if you enter Friday's date and then this date is subtracted from today's date the last day is not included in the time calculation.(Vega is not a letter in the Greek alphabet; the name arises from reading the Greek letter (nu) as.) Extensions of the model edit The above model can be extended for variable (but deterministic) rates and volatilities.So, how do you quantify that?
Your work has been very helpful in trying to understand option pricing.
