Assume a European chooser option where stock price is $10, strike price is $10, volatility is 20%, dividend yield is 0%, and risk-free rate is 4%. The choice can be made within the next six months (T1 = 0.5 years) and the option will expire in one year (T2 = 1.0 year). What is a synthetic (portfolio) equivalent to the chooser option?
答案是:A call option with strike price 10 and maturity 1 year and a put option with strike price 9.8 and maturity 0.5 year.
理解不能,求各位大牛解释一下。。。谢谢谢谢,万分感谢!!
