晶片股炸上天：Fed 按兵不動撞正 Microsoft 雲端翻叠

先更正一個數字： 原文話原油跌 $0.50 係 -0.50%，計錯。83.96 對上一日收 84.46，跌 $0.50 即係 -0.59%。銀碼啱，百分比唔啱。以下用正確數字。

晶片股炸上天：Fed 按兵不動撞正 Microsoft 雲端翻叠

收市之後，睇好嗰邊贏到出面。SPY 收 742.01，升 1.72% [1]；QQQ 收 685.66，升 3.62% [2]。兩者差 190 個點子，你估下點解？因為成個升市集中喺一條主題度，就係咁簡單。晶片股錄得 2025 年 4 月以嚟最大單日升幅 [3]，Microsoft 更加係 2008 年以嚟最勁嘅一日，靠嘅係 2022 年以嚟最快嘅雲端增長 [4][5]。

呢個分析框架點睇？呢種分化唔係推翻集中風險，而係坐實咗佢。一間 hyperscaler 出一份業績，就搬得郁成個大市——而且市場肯畀嘅價錢係越畀越高，唔係越畀越少。你話係咪咁㗎？

不過同一日入面嘅矛盾更加值得諗。Microsoft 雲端強勁托起全場，但 Meta 向存疑嘅投資者解釋 AI 資本開支之後照樣跌 [6]；Apple 中國同服務業務令人失望 [7]；最講得出嘢嘅，係 Exelon 大幅削減佢嘅 AI 數據中心排隊項目，剔走啲得個講字嘅工程 [8]。

我話你聽，呢單先係重點。電力公司係成個 AI 基建嘅水喉，佢話你知：我當初承接嗰啲需求訊號，唔係樣樣都真。大市當日仲喺度為「無限算力需求」出價，水喉佬同日執走一半訂單——「客戶係邊個都講唔清」呢個問題，係喺水喉度證實咗，唔係喺頭條度。

債市完全唔配合股市呢場煙花。10 年期收 4.663%，30 年期收 5.208% [9][10]，TLT 82.78，跌 0.08% [11]。2 年對 10 年息差 +45 點子 [12]，3 個月對 10 年 +99 點子 [13]。長債 5.21%，聯邦基金利率得 3.63% [14]——即係債市擺明唔認可寬鬆呢回事。再睇埋 PPI 按年 10.11% [15]、CPI 3.73% [16]，上游壓力仲未傳完落嚟，長息仲有排要行。

按兵不動之後，之前創紀錄嘅聯邦基金淡倉（原本係對沖加息）拆咗 [17]。但華爾街嘅判詞夠曬直接：「talk is cheap」[18]；至於暗示要出新通脹路線圖，只係令倉位更加心慌 [19]。

波動率反而最老實。VIX 現貨收 17.09，前月期貨 18.75，正價差 9.71% [20]。呢個係正常市況嘅結構，唔係壓力。IV rank 得 20.6 [21]，現貨又遠高於 52 週低位 13.47 [22]——即係話，市場既唔係大安旨意，亦都未響警號。

但係 put/call 比率 1.116 [23]，喺一個納指升 3.62% 嘅日子出現，就真係有啲怪。升到癲嘅時候對沖需求反而上升？有人喺度畀錢買佢今日根本用唔著嘅保險。你估下佢驚咩？

商品就一邊一半，而避險關係企得好穩。原油收 83.96，跌 $0.50（-0.59%）[24]，USO 跌 1.01% [25]——能源根本冇同你確認「經濟好」呢個故事。黃金就升，GLD 收 376.44，升 1.44% [26]，因為交易員喺度掂量按兵不動之後嘅 Fed 路徑 [27]。

股同金一齊升、油就跌——呢個係貨幣貶值嘅訊號，唔係增長訊號。係咁㗎，唔使諗到咁複雜。

日圓爆升，兩年多以嚟最勁，市傳日本再度干預 [28]，日本首相就要孭埋政治後果 [29]。干預即係逼資金回流，而 carry trade 條水喉，就係喺嗰度。

聽日部署：

QQQ（685.66）：企穩 690 以上就確認晶片買盤；掉頭跌穿 675，今日就只係一份業績嘅一次性事件
30 年期孳息（5.208%）：收市高過 5.25%，唔理業績幾靚都會打斷呢場升市
VIX 正價差（9.71%）：壓縮到 5% 以下代表市況轉緊；一旦倒掛，就係止蝕訊號
黃金／GLD（376.44）：股強金亦強繼續行落去，貶值呢個判讀就企得住

**要留意：**隔夜日本再干預，或者 JGB 波動。日本 10 年期 2.67% [30]，配埋兩年新高嘅日圓走勢，就係 carry trade 拆倉嘅通道——如果東京再出手、JGB 孳息又抽上，被逼平倉嘅力量會先打落美債，美股仲未知發生咗咩事。
