拆解 MU 财报前后的定价路径,认为市场在财报前已提前消化大部分利好,期权周押注并不划算。

我看到很多散户在 $MU 468 美元附近的财报上慌成一团。 一般来说,股票的重定价会在财报公布之前就发生。 例外只有一种情况:指引出现重大惊喜。 而美光这次的盈利超预期,并不是那种重大惊喜。 我的看法是: - 2026 年 1 月 25 日:公开消息传出,三星把 Q1 NAND 价格翻倍,DRAM 价格也比环比预估高出约 70%(估算当时只有 33-38%)。 机构可能提前几天就从 300 份付费供应商分析里拿到消息,所以 $MU 才会从 300 美元涨到 400 美元。 - 3 月初:又有消息称三星把 Q2 NAND 价格翻倍,这属于重大意外,比一些预期高出 20 倍,也比另一些预期高出 5 倍。 同时还有消息说三星 / SK 海力士准备在下个季度大幅提高 DRAM 价格。 但这又叠加了伊朗战争、以及更广泛的宏观恐慌导致的指数下跌。 尽管大多数标的都在大幅抛售,这些基本面变化仍然让 $MU 跑赢了那些今年跌了 20% 的公司。 在财报前,彭博终端上还有一份报告预测美光会超预期,这又把股价从 400 多美元推到 460 美元。 问题在于: 这次财报超预期的大部分内容,都是提前知道并且在整整一年里被慢慢计价进去的。 如果你读过我的帖子, - 我一直在跟踪 DRAM / NAND 价格,同时估算超大规模云厂商需求; - 也在追踪原油 / LNG / 氦气扰动对半导体供应链的影响,并把任何毛利率冲击建模进去。 这就是你该怎么给存储公司定价。 -> 财报只是证明你在财报前做出的估算是对的。 所以如果你在财报周买期权: 这真的是个很差的主意。 真正能赚到的利润,都在信息被市场知道并计价之前。

英文原文

I see a lot of retail panicking over $MU earnings at $468. In general, re-pricing in stocks happen before earnings are announced. The exception is "unless there's a major surprise with guidance". Micron earnings beat was not a major surprise. Here's my take: - Jan 25th 2026: Public news broke out Samsung was doubling NAND prices Q1, DRAM ~70% compared to Q/Q estimates of 33-38%. Institutions probably got word a few days early from 300 paid vendor analysis, which is why $MU went from $300 -> $400. - Back in early March: News broke out Samsung was doubling NAND prices for Q2, which was a major surprise, beating some estimates by 20 times, while beating others by 5 times. There was also news that Samsung/SK Hynix were planning large DRAM price increases for the next quarter. However, this was coupled with index dropping/broader macro fears from the Ukraine war. While there was a major sell-off in majority of names, these fundamental changes, likely led $MU to outperform names like $MU that dropped 20% YTD. Leading up to earnings, there was a Bloomberg terminal report projecting Micron to beat earnings, which sent the stock from $400's to $460. The thing is: Majority of this earnings beat was known in advanced and priced in throughout the entire year. If you ever read my posts, - I've been trying to track DRAM/NAND prices along with estimating hyperscaler demand: - Tracking to track crude/LNG/Helium disruption on semi supply chains and modeling in any margin impact Which is how you price in memory companies. -> Earnings are just confirmation that your estimates before were right. So if you're buying options on the earnings week: This is a terrible idea. All the profit to be made is before information is known and priced in by the broader market.
