请教一下,卖call和买put是不是差不多的?另外,如果持有正股,买put对冲岂不是很完美?或者是卖call,持有正股,岂非很完美?

卖call是赚取权利金,买put是看正股下跌,而且卖call是到期结算你才能赚取权利金的,买put只是正常的交易期权,本质上是不一样的。另一个持有正股买put或者再卖call对冲不是完美的方案,毕竟你忘记计算了购买股票和权利金的其他费用,而且不同正股其权利金的溢价也是不一样的,而且对于波动率大的股票其计算意义更小。

裸卖call权力上类似做空正股,收益有限但你的风险是无限大的。买put最大可能亏损就是你为put支付的权力金。 持有正股买put对冲是市场中很常见的行为,但你往往会发现如果一直这种做,那这种行为的成本其实很高,所以一般都是在市场不确定强的时候或者这股在高位的时候才会买put去对冲。要不一直买你股票赚的还不够买put的钱

有道理,谢谢分享

卖call买正股,这叫covered call,在市场交易里也很常见。好处先不说了。但坏处是容易丢失潜在利润,尤其是在行情好的时候。而且如果只做covered call,那账户的收益率不会很高。更合理的还是如果你的股票在很高的价位上,你可以做covered call来锁住一部分利润。如果到价被行权也无妨反正是高位。如果没到价,白赚权益金

二十年前我在赌场奋勇拼搏的时候,对不同的游戏不同的规则设定了不同的应对策略,觉得很完美。有一次转盘我拿黑色一百压一个六,中了,第二次继续一个六,又中了,dealer兴高采烈,因为我三分钟赢了8千加币,我没体现很高兴,因为那个月在转盘我已经输了一万五了。有一次 5 card porker我拿了黑桃A同花顺,赢了二万加币,dealer…我回答到几个月里我已经输了……

有些道理,短期确实投机成份很大。这次教训比较深刻,需要好好总结,以便以后再战。

非也非也,亲身经历,在加拿大有一个华人数学教授能记住Black Jack四副牌出10点的情况和概率,最后上了赌场黑名单。另一个留学生母亲是某大银行扛霸子,儿子在安省赌场输了二栋楼,报纸上都刊登了。短期投机股市类似入赌场,风险巨大。

裸卖call肯定要保证金啊,你下单的时候系统会给你计算多少钱,不同的单子定价都不一样,控制好风险,止损,切记

👌谢谢,如果有正股还需要保证金吗?多少?

持有正股买put对冲是市场中很常见的行为,但你往往会发现如果一直这种做,那这种行为的成本其实很高,所以一般都是在市场不确定强的时候或者这股在高位的时候才会买put去对冲。要不一直买你股票赚的还不够买put的钱
