A is correct. For an insurance policy, the amount of the loss that the insured is willing to bear is known as the deductible. For a protective put option, this amount is equivalent to the difference between the stock price and the put exercise price. Bochanski’s statement relates to the deductible. B is incorrect because a protective put’s time value and an insurance policy’s premium are considered to be equivalent. Neither of these are related to the protective put/insurance policy deductible. C is incorrect because a protective put’s stock volatility is analogous to the likelihood of loss for an insurance policy. A protective put’s time until expiration is analogous to the term of an insurance policy. None of these are related to the protective put/insurance policy deductible. A我懂, 但是B, C请老师分别解释下, 感谢!~

题目: Bochanski cautions that covered call options are not as effective as protective put positions in protecting the portfolio against any future downturn. He comments, “Protective put positions are analogous to insurance policies.” When implementing protective put positions, Bochanski states that factors he considers are stock price and put exercise price. Upon thinking about Bochanski’s statement, Dan Smith states that he would consider time value and upfront premium. Beauregard adds that she considers stock volatility and time until expiration. Q. In comparing insurance policies to protective put positions, whose statements most likely relate to the amount of loss that the investor is willing to bear? A. Bochanski B. Smith C. Beauregard 字数超限了, 老师请refer to 下一题, 谢谢!
