AI撐起標普500獲利成長!輝達、美光貢獻34%增幅 成最大推手

FactSet調查顯示,標普500第三季獲利預期年增30%,其中輝達與美光貢獻了約34%的漲幅。

Quick Look

FactSet調查指出,標普500第三季獲利預期年增30%,輝達與美光等10家企業貢獻了三分之二的成長。市場高度依賴AI相關投資,儘管分析師擔憂AI技術回報與投入成本不對稱,但整體市場獲利仍維持成長。

AI-generated summary

Why It Matters

標普500成分股獲利成長主要由少數AI相關企業驅動,引發市場對投資回報與集中風險的討論。

FactSet對分析師的調查顯示,標普500第3季獲利預期年增30%,其中輝達與美光就約貢獻該漲幅34%。這2家人工智慧(AI)晶片製造商,加上博通、Meta等10家企業約佔美企利潤成長3分之2,亦即標普500的獲利成長僅由少數幾家AI巨頭驅動。

華爾街日報報導,儘管這10家企業還包括艾克森美孚、雪佛龍等一些受惠於伊朗衝突引發高能源價格的油氣巨擘,但上述獲利預測表明,美國股市高度依賴幾家與AI交易相關的企業,以及搶建AI基礎設施的行動,儘管相關成本高昂。

以輝達與美光為例,對記憶體以及其他AI晶片的異常需求,大幅推升其利潤,美光上月財報顯示,其季度利潤年增逾10倍、或1078%,而預期輝達躍增90%。

分析師指出,獲利成長高度集中的風險,與更廣泛的AI投資熱潮所導致的風險如出一轍,亦即該技術最終可能無法為投入其中的鉅額資金帶來相稱的回報。

近期美股的震盪反映該風險。上週四Meta公布財報顯示,儘管其營收創史上新高,但同時提高今年資本支出預估區間的下限,以擴大資料中心投資,致使其自由現金流創下上市以來首度轉負,引發那斯達克今年以來最嚴重的一場拋售。

儘管如此,投資人對於獲利成長依賴少數幾家公司推動的局面不太擔心,主因在於整體市場的獲利仍在成長,只是增速放緩。MAI資本管理首席市場策略師格里桑蒂(Chris Grisanti)說,即使排除上述10檔股票,預期第3季標普500其餘成分股的利潤成長年增10%,考慮到這波牛市已進入第4年,這樣的表現已相當不錯。

不過,他也說,其團隊正為獲利成長放緩做準備,從「賣鏟子」類股轉向增持電力供應商,該思維乃是依據:隨著資料中心的建設推進,即使記憶體的供應緊繃局面緩解,電力需求仍將持續升高。

Open Questions

  • AI基礎設施的鉅額投資何時能轉化為穩定回報?
  • 電力供應類股是否能有效對沖AI硬體類股的波動?
