同学,上午好。statement中,+call是long call,而+put是short put(buy five contracts of June 120 calls. Alternatively, she notes that Patel write five June 115 put contracts. )
Statement 1:long stock+long call,组合delta=1+0.439=1.439,只要delta>0,就是看涨(此处股价变动1元,组合价格变动1.439);long stock+ short put,组合delta=1-(-0.399)=1.399,也是看涨。同时,long stock+long call看涨的更加强烈。所以1中描述是错的
