Micron(MU)核心投資邏輯

核心看點

HBM 是最大護城河之一:AI GPU/ASIC 對 HBM 需求高速增長,目前主要由 SK hynix、Samsung、Micron 三大廠供應,先進 HBM 技術、良率及客戶認證門檻高。

供需仍偏緊:Micron FY2026 營收 $133.2B、Non-GAAP EPS $75.52;FY2027 Q1 指引營收 $61.5B ±$1.5B、EPS $38.15 ±$1,公司預期 FY2027–28 記憶體供應仍偏緊。

AI 不只是 HBM:AI Server 同時帶動 DRAM、HBM、SSD,HBM 又會消耗 DRAM wafer capacity,有助維持整體記憶體價格。

最大長期風險:2028–30 年新產能大量開出,若 AI 需求增速放慢,可能重新出現「供過於求→ASP下降→毛利率下降→EPS下跌」的記憶體週期。

中國是中長期變數:CXMT 正逐步進入 HBM,但目前在先進製程、良率及規模上仍有差距;若 2029–30 年中國 HBM 大量量產,可能削弱三大廠的供應集中度。

目標價

邏輯

🔴 Bear

$700–900

記憶體週期反轉、ASP下降

🟡 Base

$1,100–1,500

HBM/DRAM維持高需求

🟢 Bull

$1,600–2,200

AI需求持續+供應緊張

🚀 Extreme Bull

$2,500–3,000+

HBM長期供不應求+估值重估

目前 MU 約 $1,088;市場近期目標價分歧很大,例如 Morgan Stanley $1,200、Mizuho $1,400、RBC $1,500、TD Cowen $1,600、Cantor $2,000,而 DA Davidson 最新大幅上調至 $3,000。

我的核心結論: MU 現階段最大的優勢是「AI+HBM+DRAM供應緊張」,最大的風險不是 AI 不需要記憶體,而是 2028–30 年產能擴張速度超過需求增長。

    我算咗下,照Q1指引年化接近250B,市場仲未完全定價呢個斜率

    真要看風險 我更盯三星海力士擴產節奏,三大廠先內卷都唔奇
