举例:CLDA March OM Call的IV是135%, Put 的IV是155%。也就是说,Put比Call贵了。于是卖Put买Call不就有钱可赚啦。方法更简单:卖Collar with Stock。有$350,000就一个月拿$6,000的收益,应该不错的,比定存好多了, 甚至好过许多基金,毕竟这是零风险的。
Sell "Collar with Stock": Sell short 10,000 share of CLDA, Sell 100 March 33 Put, Buy 100 March 33 Call. Your position is 100% neutral, i.e., no matter where the stock go, you maitian zero gain or lose, except the premium you cellected from selling put-money you buying calls. You need $330,000 to short 10,000 shares CLDA as Friday's closing price.明白?
