Aline Nuñes, a junior analyst, works in the derivatives research division of an international securities firm. Nuñes’s supervisor, Cátia Pereira, asks her to conduct an analysis of various option trading strategies relating to shares of three companies: IZD, QWY, and XDF. On 1 February, Nuñes gathers selected option premium data on the companies, presented in Exhibit 1.
Nuñes considers the following option strategies relating to IZD:
Strategy 1: Constructing a synthetic long put position in IZD
Strategy 2: Buying 100 shares of IZD and writing the April €95.00 strike call option on IZD
Strategy 3: Implementing a covered call position in IZD using the April €97.50 strike option
Strategy 1 would require Nuñes to buy:
选项：
A.shares of IZD.
B.a put option on IZD.
C.a call option on IZD.
解释：
C is correct.
To construct a synthetic long put position, Nuñes would buy a call option on IZD. Of course, she would also need to sell (short) IZD shares to complete the synthetic long put position.
