跨式期权该怎么做？

2017-05-21

$Advanced Micro Devices Inc.(AMD)$
AMD目前受到前期12.7阻力，在11.5左右盘整，月线上看没有止跌，日线上涨受压制，我看不清楚未来的走向。
看到书上讲，不能判断变动方向时可以买入相同数量、相同行权价、相同日期的买认购和买认沽期权，可以形成组合式期权，叫买跨式。
又讲该组合的最大损失=买入认购权利金+买入认沽权利金，理论上最大收益无上限，只有当标的证券价格波动超过盈亏平衡点，该策略才会盈利。
请教:
1.买入最大损失为什么是两个权利金的和，怎么理解？
2.理论收益无上限，又怎么理解？一买涨，一买跌，@核桃妈 @A股45度不应该有个平衡点（收益最高点）吗？
3.波动超过盈亏平衡点，该策略才会盈利。还是不理解，请看图片，图中显示该组合有两个平衡点，是低于下平衡点或高于上平衡点，才会盈利吗？
4.AMD目前是否适合买入跨式策略呢？

刚才讲的不太对，我用例子说说，6月2号11.5的call和put分别是0.38和0.48的价格。
先讲到期行权的情况
一.如果你买了以后不操作等到6.2号，股价还是11.5，这就是你的最大亏损，你花钱买了两张废纸
二.不操作直到2号股价12.3或者10.7，你大约盈亏平衡。假设amd2号涨到20块，你的call就翻了好多倍，但是你put就废纸了
- 美游回复hypnus:
  我在BABA财报就是这样想的，但有正股，就没有采取这样方式。
- hypnus回复Tony特别帅:
  😂因为他的提问就是收益为啥没有上限嘛，所以讲极端情况。。这好事有啊。前几天不是第一天涨十几，第二天跌十几吗，情况是有的，只是谁能操作的这么**
- 美游回复Tony特别帅:
  有这样的好事都这样操作啦，稳赚🤣🤣
- 美游:
  大幅波动是基本要求。股价在1块钱左右上下，基本无钱可赚，到期两张废纸
- Tony特别帅回复hypnus:
  理解没错，但平常哪有这样的好事。。😂

举个很粗糙的例子，比如你花0.5块钱买了行权价13元的call，花0.5块买了行权价为13块的put，假如现在股价13元，那至少要上下波动超过1块你才有的赚
- 九格回复长线投资者:
  是的，跨式大概也就适合某些妖股玩财报吧，比如奈飞之前都是10+%的波动，不过这种情况很少
- 长线投资者回复九格:
  没错。我自己略做过估算，振幅5%基本是临界点，以下完全不挣钱；5% -10%赚小钱；10%以上非线性增长，越妖挣钱。具体到amd，股价和期权的相关度弱于牛股，这么玩其实收益很一般，甚至没啥意思。
- 九格回复Tony特别帅:
  是啊，所以跨式对盘整的时候来说是很坑爹的
- Tony特别帅:
  因为你买期权总共花了1块，按13涨到14call至少价值1块，put跌为0基本上，那你算算1÷13是涨了多少，至少7%。。。

不管是否用什么方式进行期权投资都要注意风险，不管怎样的组合都不能保证你有盈利因为你永远不知道股价怎么走你自己又如何能控制情绪调整心态这些纸上谈兵的东西不能保证让你赚钱的
记住期权是很危险的东西，多空都可以双杀，这也是个无底洞，不要轻易补仓，要有止盈止损的规则，除非你认为有很明确的走势。哈哈，都太难了，期权交易者能活下来的不多，我死过两次，交了大比学费！做好亏光的准备吧！

我喜欢给人泼冷水
上周四我买了gap的双向期权最后结果并不好自己总结是无法判断市场走势自己操之过急在上周五的情况让人都很失望有空你去看看这个票子上周五的信息面盘面和期权
所以会买双向期权没用，如何判断在什么时候了结他们才是关键那就判断正骨走势这个就是扯淡的事情了 😂

感谢各位前辈热心指导，使我受益匪浅，尤其是@Tony特别帅 ,@hypnus @蓝天白云，举例说明，我一下子就豁然开朗了。也非常感谢美股论坛中的互相学习，经验交流的氛围，A股中骂娘的环境真是没法比。

最近在看损失模型……… 波动率小的话跨式期权就被波动吃掉了…… AMD我也看了蛮久的…… 以季报为周期看波动其实蛮大的。所以做跨式的话我建议是周期放长些。当然。时间价值就被吃掉了。 😂😂 所以价外期权稍微好些如果你本金有限。当然我还是建议长期的价内期权。
