第五本教材equity&fixed-income,第39页:
The put contract holder has the right to sell the underlying to the writer. The holder will benefit if the price of the underlying falls, in which case the price of the put contract will rise.
The holder is long the put contract and has an indirect short position in the underlying instrument. Analysts call the indirect short position short exposure to the underlying. 这里的indirect short position, short exposure这么解释呢?
另外下面这个表具体又是什么意思呢(就是书上39页的表格)?主要是exposure to underlying risk 不明白啊。。。。
type of position option position exposure to underlying risk
call long long
call short short
put long short
put short long
跪求各位大神解答,感激不尽啊~~~~~~~~~~~~~~
