问题如下:

Arnie Burr is CEO and chief investment officer of Princeton Capital, a registered investment advisory firm. He is working with Tom Jeffinsin, head trader, and Jim Madisox, a new analyst. They meet to discuss option valuation methodologies in the context of the firm’s use of derivatives to manage client portfolios.

Burr begins the discussion by stating that the Black–Scholes–Merton (BSM) model is a relatively straightforward tool for valuing options despite its rigorous computational components. Burr writes the BSM model on the firm’s whiteboard, presented as Exhibit 1.

Exhibit 1: BSM Model for Options on Non-Dividend Paying Stocks

Burr wants to assess Madisox’s comprehension of the components of the BSM. Madisox states that a call option can be viewed as a leveraged position in the underlying stock. To replicate a call option, the appropriate strategy is to purchase N(d1) shares and simultaneously borrow an amount erTXN(–d2).

Madisox’s statement about the BSM model is least likely correct with respect to:

选项:

A.

purchasing N(d1) shares.

B.

the leveraged position in a stock.

C.

borrowing an amount e–rTXN(–d2).

解释:

With respect to a call option, Madisox is incorrect with respect to his comment to simultaneously borrow an amount e–rTXN(–d2). To create a leveraged position in a stock, the correct components are to purchase N(d1) shares by borrowing an amount e–rTXN(d2). The term e–rTXN(–d2) represents the amount lent when purchasing a put option.

N(d1) is probability.


不是因该买h shares, 不是买 N(d1) shares。

嗨,爱思考的PZer你好:


N(d1)就是看涨期权的Delta, 也就是hedge ratio。可以去看一下BSM公式,call option的价格对股票价格求一阶偏导数就是N(d1)。
