22章不是讲的an option on 100 shares stock

NO.PZ2020011901000080

问题如下:

A trader thinks that the price of a stock currently priced at USD 70 will increase. The trader is trying to choose between buying 100 shares and buying European call options on 1,000 shares. The options cost USD 7 per option and have a strike price of USD 70 with a maturity of six months.

What is the breakeven stock price for which the two strategies give the same result? (Ignore the impact of discounting.)

选项:

解释:

We require

100(ST - 70) = 1,000(ST - 70) - 7,000

or

900ST = 70,000

The breakeven stock price is therefore 70,000/900 or 77.78.

22章不是讲的an option on 100 shares stock,那不是应该买了10份option?

嗨,从没放弃的小努力你好:


同学你好,

题目说了一个option对应100股就按100股,如果题目没说,那就默认是对应1个。
