包子求解答：卖扑的最大损失一问# Stock
w*k
1 楼
看了几个网页，都说卖扑的最大损失是unlimited。比如这里
http://www.theoptionsguide.com/uncovered-put-writing.aspx
这么说
Unlimited Downside risk with Little downside protection
While the premium collected can cushion a slight drop in stock price, loss
resulting from a catastrophic drop in stock price of the underlying can be
huge when implementing the uncovered put write strategy.
The formula for calculating loss is given below:
Maximum Loss = Unlimited
Loss Occurs When Price of Underlying < Strike Price of Short Put - Premium
Received
Loss = Strike Price of Short Put - Price of Underlying - Premium Received +
Commissions Paid
再比如这里，也说是max loss is unlimited

但是我觉得最大损失就是strike price，也就是说股价跌到零，我还是要在strike
price买进股票，每股最大损失就是全部股价。虽然是巨大损失，但无论如何也不是
unlimited的不是？
