      sell put 保证金的计算,重要!

      @食贝者
      最近比较火热的一个话题是裸卖put, 裸卖put确实是一种好的策略,也是巴菲特早年比较推崇的策略之一。顺便说一句,巴菲特现在不做股票期权了,因为他的资金量太大,股票期权无法容纳。如果风险控制得当,sell put这一策略可以获得稳定收益。裸卖put实行的是保证金制度,也就是说,你必须有一定量的现金或股票作为保证金才能开仓,且开仓后需维持一定量的保证金。看到有几个虎友分享了他们卖put的历险经历,跌宕起伏,扣人心弦。由于正股大跌,导致保证金急剧上升,为避免被强制平仓,最后不得不自行割肉某些寸头,或者紧急从别处腾挪资金救急。归根结底,是大家对保证金的计算不了解,不重视。很多人开仓完成后就不太关注保证金的变化,尤其是在涨势中。好像没有太大风险。但是,一旦进入跌势,如果你对保证金的计算不了解,将面临被强制平仓的风险。我们开仓之前,必须对最坏的情况做个估计。比如,我开了这么多的仓位,初始保证金是多少,行权日到达之前,股票价格下跌到行权价附近,此时维持保证金变为多少,当股价大幅低于行权价时,维持保证金又会变为多少。关于保证金的计算,各家券商都有自己的算法,但这些算法的基本构架是相似的。各家在基本构架外再考虑一些别的因子。下面就以盈透证券的算法为例来给大家讲讲sell put的保证金算法。Sell put的保证金分为两部分:1,期权金。所获期权金必须拿出来做为保证金的一部分。这部分在整个期权存续期间不会变化。2,由于sell put最坏的结果是要接股票,所以你必须准备一部分资金(现金或股票),但不必准备100%接股票的钱。这部分钱是这样算的:或者20%股票现价减掉虚值额,或者是10%行权价,二者取大者。这样的描述有点烧脑,还是举个栗子吧。比如你卖了目前股价为50元,行权价为40元的put。20%*50=10,虚值额为50-40=10,二者相减等于0,这种情况就选10%行权价作为保证金的一

      实际上有一些有趣的读物$Sono Group(SEV.US)$电动车1.索诺汽车(Sono Motor)的“锡安”(Sion),将成为第一价格实惠的太阳能电动汽车,21429欧元(不含增值税)2.许可为太阳能提供动力的技术(这将对其他公司有用。例如,为政府、学校和其他公司提供班车的EasyMile将是第一家将这项技术集成到其车辆上的公司3.电力共享功能,通过Sono APP,其中一项功能就是电力共享。(可以用它给其他车充电吗?!我想也可以用在其他用途上。)4.他们曾在柏林IDTechEx展会上荣获“电动汽车最具意义创新奖”这是一家有可预见潜力的公司。为了不同的目的,已经与不同的公司建立了合作伙伴关系;博世、西布罗斯等。虽然还没有实际生产,但他们已经结束了。3.5亿从顾客那里得到了价值不菲的预订。这些只是我遇到的一些东西,相信还有很多其他的东西。https://thedriven.io/2021/01/13/sono-motors-reveals-34000-sion-solar-car-you-can-really-afford/amp/https://www.european-business.com/news/sono-motors-announces-bosch-as-partner-for-car-connectivityhttps://www.prnewswire.com/news-releases/sono-motors-reaches-14-000-reservations-worth-over-350-million-301367552.htmlhttps://www.electricvehiclesresearch.com/articles/11031/idtechex-electric-vehicles-europe-2017-award-winner$

      $苹果(AAPL.US)$Aapl did a good rally yesterday to break 152 resistance as expected and even went up to test 155 resistance.Aapl being a market moving stock it is important to note that if Aapl is in a bull rally which is what we currently have now, likely the market will also rally together. Ndx/QQQ also broke out of bullish wedge yesterday and did not close back below the wedge trend line.Does this mean Aapl will go back up to retest 155 straight and break new high? Maybe. But I feel it may go sideways for abit or even pullback a little due to OpEx this week to eat up time decay and to let options expire worthless. When Aapl breaks the 155 resistance, it is almost clear to say it will break 157 high and create brand new highs at 162 or even 164. So sit tight and let the market do its thing.
