先说结果，A股本人有一定的盈利，只做现货；美港股现货、期货、期权都做，期权居多，一年半以来，收益基本原地踏步。1500usd入市，现1780usd……一句话总结就是:拿1万块钱在折腾。以下是我的美港股交易结果12.18实时背景：理工科专业毕业，曾经在互联网、VC和二级市场基金都有过工作经历。对于经济和商业运行有一定观察。现货交易胜率在80%以上，偏中长线持股，持股周期在1月-1年。美股账户偏中短线交易，最近一年（2020.11-2021.12）主要做期权。收益率20％总体来说，美股交易上，我经历了三个蜕变阶段：２０２０年夏天７月到２０２０年１１月（看宏观，做现货投资）；２０２０年１１月到２０２１年５月（看宏观，做期权交易）２０２１年５月－２０２１年１２月（宏观微观结合，做期权交易）。开始交易期权的契机，是在去年11月份，当时看到了一个社区朋友，@郭博文2020年年初5万rmb起步，年底做到了400万。他数学系背景，主要做期权。当时真得承认我是羡慕的，于是自学了期权基础知识后，开始交易。去年11月-今年4月，我持仓期权主要是短线交易，持仓3天到一个月之间。然后，收益率就是大幅波动。当时主要做新能源股（蔚来NIO、理想LI、小鹏XPEV、法拉第未来）、石油股（OXY,CPE）、数字矿业（Mara、RIOT)。有一段时间运气超好，连续做对4次蔚来$蔚来(NIO)$短线期权，但第5次折戟了。总体来说，小赚。后来又看了同龄大神@郭博文的交易，反思了一下，开始转型做中线期权，持仓在半个月-3个月。然后仍然
