涉及标的： $MU
回到一月份： 我当时用便签式的粗算方法，拿美光的财报毛利率预测和官方指引做了对比。 我的原话是： “如果 $MU 指引 2026 年 Q2 的毛利率为 68.0%，而 NAND 价格从估算的 33-38% 直接上涨 100%， 那毛利率预测就可能被推到 73-75% 以上。” 华尔街当时的共识大概就在 67% 到 69% 左右。 而当 $MU 真正公布财报时？ 74.9% 的毛利率，正好落在我当时预判的 73-75%+ 区间。 这就是为什么信息会在财报前就被提前计价。 所以这根本不是一个“意外结果”，因为连我这种普通人一月份都已经能估出来 / 提前计入定价了。
Back in January: I napkin-math modeled Micron's earnings margin projections vs. their official projections: My quote: "If $MU guided for 68.0% gross margins Q2 2026, and we see a 100% NAND hike from 33-38% est. That could bring gross margin projections over 73-75%." Wall Street consensus was sitting right around 67% to 69%. When $MU reported earnings? Their 74.9% margin landed in that predicted 73-75%+. This is how people price in information early, before the actual earnings. So it's not a "Surprise Result" when even people like myself could estimate it/price it in, back in January.
