问题如下：
How is a protective put created? Why would a trader create such a position?
解释：
A protective put is created from a long position in both an asset and a put option on the asset. The motivation is setting up protection against downward movements of the asset price while anticipating profit generated by upward asset price movement.
能不能麻烦老师帮忙总结一下protective put和call的构成啊
