正股+卖call对冲_老虎社区_美港股上老虎

2018-12-07

正股+卖call对冲疑问。希望给位前辈老师能指导一下，谢谢。

持有7手 $New Age Beverages Corporation(NBEV)$ 的正股均价4.5usd, 昨天看了 @TESLA到碗里来一篇对冲的帖子，卖了7张 1221 5c的Call ，期权价0.3。现在正股收盘价4.78，期权价0.45.

是不是可以这么理解：

1221如果股价刚好到5或以上，被行权，那么收益是 0.3x700+(5-4.5)x700=560，正股被交割?（相当于同时卖出正股和平仓卖call)

1221 如果股价低于5，比如4.9或者4.2，那么收益是 0.3x700=210,正股还留着，也可以操作卖出获得收益或继续持有？

上面2点比较好理解。

现在的疑问是：如果1221之前股价到5或以上了，比如1208，期权价可能是0.5或者0.55，会不会被行权？如果被行权那么我的收益是不是变成

（5-4.5）x 700+(0.3-0.55) x 700=175?.

如果开盘直接6或者以上，是不是直接被行权，也按上面那个公式收益?

最近在看麦克米伦的《期权投资策略》第五版，很多似懂非懂。

我现在就是这个策略，只是我持有的苹果正股，周一卖出周五的call，每周都卖，行权价自己权衡。我觉得你要卖call必须要考虑的就是流动性，我视线内的苹果和qqq期权的流动性都很好，卖call可以止盈也可以降低成本，相应的也可以卖出put来建多仓，卖出call来建空仓。这是我的心得，不知道对不对
- 芸芸树下回复第二菠萝:
  额，跨式期权还不知道怎么操作。其实还不懂，只是刚好有疑问，先弄明白再操作。谢谢您！
- 第二菠萝回复芸芸树下:
  这种经常暴涨暴跌的可以采用跨式期权策略啊，何必买正股卖期权承担那么大风险
- 芸芸树下回复第二菠萝:
  明白了，谢谢您！因为之前观察了好几只股盘前一段时间暴涨，结果开盘后暴跌10月17号的大麻股，11月12日的$阿玛琳(AMRN)$ ，也就是可以利用这个时间差可以收益超过行权价，当然风险也大。
- 第二菠萝回复芸芸树下:
  对啊，相当于在5块建了个空仓，还是看多的话只能开盘平仓
- 芸芸树下回复第二菠萝:
  就是如果利用盘前盘后在行权价以上清空正股，开盘后如果call买方行权，那我的正股就是-700，是不是相当于在5的股价上做空？

股价高于5，多余的收益就和你没关系了，即情况1。至于期权，由于股价上涨，期权的收益会出现浮亏，等收盘交割完股票，就不会了，0.3*700的权利金仍是你的，那个浮亏是临时的。你也有另一个选择，如果股价到5了，想卖了，但又怕期权后面被行权，就可以亏了平仓卖出的期权，再卖出正股，完事了。但这样收益就少了，但避免股价再次下跌的风险，原则上讲，任何对冲都有成本。
- 芸芸树下回复sz大渔:
  谢谢您。
- sz大渔回复芸芸树下:
  没错，👏👏
- 芸芸树下:
  谢谢您，又学到一招。
- 芸芸树下:
  就是说，这票我可以在1221之前不管它了，最少收210的权利金（不考虑正股浮亏浮盈），最多收（5-4.5）x700+210=560。其实正股如果设定的5就卖出止盈，卖5call相当于多挣了210的权利金？

刚起床，没做细分析。送给你一个简单粗暴方式: 再好的对冲也不可能做到0风险。所以不要去在乎这点蝇头小利。不加杠杆做正股，以正股养期权，以求获得更大收益。按你的资资金量初始资金500到就可以。风险很低，但是潜在收益非常客观！
- 芸芸树下:
  谢谢您。正股养期权？不懂怎么操作。

  指数级增长很恐怖！

只看行权日的价格，而不看之前的价格。
- 芸芸树下回复核桃妈后援团团长助理:
  谢谢您，不过还不理解什么是价内、价外，深度价内，先慢慢看书，如果以后有问题请教您还望多指导下。
- 芸芸树下:
  谢谢您。就是卖call的浮亏是不用管，只要不是主动平仓就不会亏损，这个权利金始终是自己的。到行权价了，正股交割。

  每个人的操作方法不同，我一般是操作流通性较好的股，如TSLA，一周一周地卖，一周几百刀入手☺
