持有过财报,MU教给我的事

投资者摘要看多

分享应对MU隐含波动率暴跌的期权策略,基于客户220亿美元预付款对其长期基本面保持看多。

看多要点
  • 长期基本面极其强劲,客户为长期合同预付了220亿美元现金,释放了强烈的看好信号。
  • 财务业绩达到历史级别,营收达414.6亿美元,指引中值为84.9亿美元,展现出强劲的业务动能。
  • 股票动能强劲,年初至今上涨325%,表明市场对公司发展轨迹充满信心。
看空要点
  • 散户在信息获取上相比机构处于显著劣势,仅靠猜测财报超预期几乎不可能战胜机构。
  • 财报前极端的隐含波动率(IV超过180%)意味着市场已消化了巨大涨幅预期,导致财报后出现严重的IV暴跌。
  • 财报前的高估值和已被消化的预期限制了裸看涨期权的上涨空间,正如盘前剧烈震荡所显示的那样。
MU财报季半导体
帖子正文
高质量模型翻译结果

美光(MU)昨日盘后公布了财报。收盘上涨15.74%,盘中一度冲高至+18%。但盘前15分钟的K线从+18%一路回落至+8%,随后又迅速反弹至+13%。如果你在周四收盘时持有裸露的看涨期权,这10%的盘前波动就足以让你被强制平仓。

这是我第三次交易MU期权。2023年,当MU公布58亿美元亏损时,我买入了看涨期权,当时大家都觉得我是个傻子。到了2025年,面对同样的58亿美元亏损,我又买入了看涨期权,大家还是觉得我傻。而这次,营收达到373亿美元,我反而卖出了看跌期权,结果被说太保守了。本轮操作中,我持有一个1150行权价的跨式价差组合(calendar spread),没有做任何裸多头。为什么?因为财报公布前一天,MU的隐含波动率飙升至180%以上。这种水平的IV意味着市场已经定价了一个8%到12%的大幅波动。果然,实际数据——414.6亿美元营收、84.95亿美元利润,以及373亿美元的中值指引——每项都创下历史纪录。但市场早已提前消化了这些信息。

MU今年至今已上涨325%。此时你的优势并不在于猜测财报是否超预期。在如此严重的信息不对称下,散户永远不可能比机构反应更快。真正的优势在于次日开盘后的伽马衰减和IV骤降。一旦财报发布后市场开盘,虚值看涨期权的隐含波动率会从180%暴跌至60%或70%。这种衰减速度远超大多数人的预期。

我的策略框架:如果你必须持仓过财报,避免使用裸期权。建议采用跨式价差组合,卖出近月合约,买入远月合约,以对冲IV骤降带来的损失;或者直接使用价差组合(debit spread),将最大亏损控制在可接受范围内。还有一条我用血的教训学到的经验:不要在财报公布后立即重新建仓。至少等待30到45分钟,让伽马和IV完成重定价。之后看到的支撑与阻力位才是真实的市场共识,而非开盘时的情绪冲动。

我对MU的基本面长期看好。其长期客户SCA合同已提前支付220亿美元现金。这个信号比任何分析师的目标价都更有说服力。但基本面是一回事,仓位管理又是另一回事。还有谁在财报前后持有了MU?你们是怎么对冲的?

Not trying to be insulting, but this is not a repeatable predictive lesson, it's the pattern seeking superstitious type reasoning you see with people who win at slot machines.

I think the worst part about this thread is they made it after the earnings. After they survived. MU tanks post earnings this thread doesnt get created.

All the traders who read this are gonna be mad

I am holding MU and RAM. I got in late, so i won't make as much money as some other earlier people, but i am still making a lot of money. Good enough.

u/Live-Past4287 5· 2 天前

That’s the healthy way to look at it. Late entries just change the risk profile, not the validity of the trade.

u/turnleftorrightblock 3· 2 天前

Yeah, only kids whine "i want a pie as big as that guy or no pie at all, i am gonna look for some other big pie". That is a manchild mentality. I am making huge percentages cumulatively even at late entry.

u/Live-Past4287 4· 2 天前

The more relevant question is whether the remaining expected move justifies the risk at this entry point. Percentages don’t matter much if the distribution of outcomes shifts.

u/AngronTheDestroyer 3· 2 天前

Isn’t it risky to hold ram since it is x2 leverage considering days like this when it is down significantly?

This is my third cycle trading MU options. Back in 2023, when MU posted a 5.8Bloss,IboughtcallsandpeoplethoughtIwasanidiot.In2025,with5.8Bloss,IboughtcallsandpeoplethoughtIwasanidiot

Saddled with Korean stocks up 200% ytd and 300% ytd yes

the real edge here isn’t predicting MU, it’s surviving IV expansion and crush cycles

u/Live-Past4287 4· 2 天前

Everyone talks about direction, but MU is mostly a volatility regime trade. Surviving IV expansion and crush is basically the actual skill.

DRAM all the way

u/AngronTheDestroyer 3· 2 天前

How do you feel about dram considering it has somewhat dropped the last couple days and plateau’d? Correction or signs of the non stop rise is unsustainable?
