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
