美股期权入门,看完这篇全懂了

这是目前根据期权模型计算出的期权价格为58美元,假设目前的95.52的iv(隐含波动率)不变,我们把日期拉到12月20日,股价上涨到650,我们再来推算得出的期权价格为54.08美元,随着到期日的临近,即使股价上涨了11美元,您的期权也会亏损(58-54)*100=400美元,更有很多比较激进的投资者甚至买入距离当前股价较远的价外期权,这样随着到期日临近只会加剧亏损,通过简单的期权定价模型我们很容易看出之前那个人为什么会亏损,所以我们普通投资者在做期权买卖的时候一定要计算好再买入

根据我们之前所讲的,当iv>hv的时候更适合卖put,这时候的特斯拉我们可以选择卖出put期权来获得权利金的收入,这里我就不给大家细算了,看完文章后可以自己使用老虎证券推算一下

通过上面的案例我们反推一下,当iv<hv的时候我们就可以买call,昨天我在我的投资社群已经分享过,有人用2万元买蔚来股票,通过期权一年赚了1300万,当然,期权只是一种投资工具,你会用的同时还需要对这家企业有着强大的基本面分析,如果您对一家公司不够了解的情况下使用期权,这无疑跟赌博没什么区别!

影响期权价格主要三大因素是:到期日、行权价、波动率

到期日理解起来不难,您看涨或者看跌一只股票,需要在这上面加一个时间,期权价格大部分是由时间价值和内在价值组成,在股价不涨不跌的情况下,随着时间的流逝,您的期权一直是有损耗的,所以,时间价值是期权的最大杀手

行权价也很好理解,您看涨或者看跌一只股票,在加上到期日的同时还需要定一个价格,这里我给大家展示下当前纳指QQQ期权链的到期日和行权价,最接近当前股价的行权价是304,如果您要做多大盘,低于304的行权价就是价内期权,高于304行权价的期权是价外期权,如果您要做空大盘,价内和价外期权正好相反。

在这里提示大家一点,无论是做多还是做空,尽可能选择距离当前股价最近的行权价,如果您买的是价外期权,一但股价波动太大,虚值期权的损耗也就会更大

看好一只股票,感觉近期会上涨,但是隐含波动率iv大于hv,买call不划算,应该怎么用期权?

第一种方法上面已经提到过,直接卖put赚权利金,这个方法跟上面讲过的巴菲特卖naked put一个道理,这里我就不详述了

Naked put的风险是一但股价跌穿行权价,您需要买入对应的正股,对于一些资金较少的套利投资者不太友好,在这里老鲁给出第二个套利策略,那就是

bull put spread 牛市垂直价差组合

我们还是以特斯拉为例,我买入一张2020年12月31号到期 试试港美股期权 试试港美股期权 行权价630的put看跌期权 buy TSLA 201231 put 630

然后我再卖出一张2020年12月31号到期 行权价640的put看跌期权sell TSLA 201231 put 640

大家都知道,买put是看跌,卖put是看涨,一个看跌一个看涨,说白了就是锁定超出的收益部分,来弥补亏损部分,组合出来的策略收益是这样的

bull put spread 牛市垂直价差组合它的优点是您只要看准方向,无论是涨还是跌,方向蒙对了,这钱您就算拿到手了

相信讲到这里有朋友会问,如果一只股票iv隐含波动率很低用什么策略呢?

bull call spread ,这个理解起来很简单,波动率过高我们卖put,波动率过低我们买call,这个策略是买一个call的同时再卖出一个call,理论上盈亏图跟上面的是一样的,这里我就不详述了,我相信文章能看到这里的朋友基本可以举一反三了

垂直价差还有bear call spread和bear put spread,这两个是看跌策略,如果您觉得关注的股票要下跌,就可以买入这两种期权组合,同样,如果方向蒙对了,权利金您就能拿到手,价差组合目前是套利者应用最多的期权策略,相比较单纯的买call和买put,胜率都提高了很多
