估值迷思:Nvidia 現價真係平咗?

作為早期買入 Nvidia(NASDAQ:NVDA)股票的投資者,我自問都幾自豪。不過,雖然帳面上賺咗唔少,但實際利潤波動極大,因為 Nvidia 同好多美國科網股一樣,最近股價變得極之波動,壓力多數向下。

正因如此,好多投資者(包括我)都開始質疑:Nvidia 依家係咪被低估?不如用數據睇清楚啲。

Nvidia 依家用最簡單的過去市盈率(P/E)計,已經跌到 33.6 倍,係過去五年最低位。雖然歷史平均數唔代表一切,但呢個指標值得留意。

不過,單靠過去市盈率唔夠全面,更重要係預測市盈率(forward P/E),依家大約 21 倍,顯示公司盈利預計會持續增長。

事實上,市場估計 Nvidia 中期平均盈利增長有 35%。計埋增長後嘅市盈率(PEG ratio),只有 0.62。雖然市盈率比行業平均高,但 PEG 反而比行業平均平咗 53%。

但呢度就有風險。如果公司未來增長未如預期,股價隨時會大跌。另一方面,Nvidia 自從 AI 熱潮開始後,佢嘅市銷率(price-to-sales ratio)都未試過咁平。

會唔會一沉百踩?

Nvidia 依家係 AI 晶片市場絕對霸主,佔有 70% 至 95% 市場份額,全靠佢先進 GPU 同 CUDA 軟件生態圈。不過,2025 年開始,形勢有變。

中國新勢力 DeepSeek 冒起,佢哋開發咗新 AI 訓練方法,可能減低對 Nvidia 專用晶片同 CUDA 嘅依賴。長遠嚟講,如果 AI 模型變得更高效,對 Nvidia 晶片需求可能會減少。

再加上地緣政治風險。特朗普總統對關稅政策朝令夕改,令科技板塊波動加劇,特別係晶片零件同豁免問題。雖然 Nvidia 宣佈會將部分生產線搬返美國,以減低關稅風險,但全球供應鏈始終受政策變動同出口限制影響。

同時,AMD 等競爭對手亦虎視眈眈,能否分一杯羹仍有待觀察。

總括而言,Nvidia 面對多重挑戰,但現時盈利預測同 PEG ratio 又顯示股價被低估。形勢複雜矛盾。我自己都心郁郁想加碼,但股價實在太波動,暫時都係觀望一下。

編輯評論:Nvidia「平」價背後的兩難

Nvidia 依家無論用傳統市盈率,定係增長調整後市盈率(PEG),都顯示相對「平」。但「平」唔一定等於「抵買」,因為佢背後係市場對未來增長的極高預期。AI 熱潮將 Nvidia 推上神壇,但市場一旦對增長失望,股價隨時暴跌。

值得注意嘅係,Nvidia 依家最大風險唔止來自競爭對手,而係技術范式轉移同地緣政治。中國新玩家可以繞過 CUDA 生態圈,令 Nvidia 的護城河變窄。特朗普式貿易戰亦可能令供應鏈成本大增,影響盈利。

而且,AI 晶片需求會唔會長期保持高速增長?定係只係一時熱潮?如果 AI 模型效能提升,對硬件需求反而減少,Nvidia 會唔會變成下個 Intel?這些都是值得深思的問題。

總結:Nvidia 依家或許「平」,但其實係未來增長的賭注。對於香港投資者而言,買入前要諗清楚自己係咪真係睇好 AI 長線發展,同時要預備承受極大波動。與其盲目追捧,不如考慮分散投資,減低單一風險。Nvidia 係唔係你 portfolio 的必選,未必有標準答案,但至少要知道,依家入場,已經唔再係無風險的「穩賺」遊戲。

Two playful cats, one sleek black and one fluffy ginger, are joyfully interacting on a bustling Hong Kong street at sunset. They leap and tumble among vivid neon signs, glowing red lanterns, and traditional market stalls. The scene is bustling with locals and dotted with elements of Hong Kong architecture, such as narrow alleyways, decorative shopfronts, and overhead laundry lines. Warm golden light reflects off the wet cobblestone street, casting dramatic shadows. The atmosphere is lively yet whimsical, capturing the vibrant urban spirit and blending realistic feline anatomy with a touch of enchanting artistry. Rendered in hyper-detailed, cinematic style with rich colors and dynamic composition. Use the original face exactly as it is, without changing a details. A striking, high-fashion editorial portrait of a white -skinned model, captured outdoors with a bright, sunny, slightly hazy ambiance reminiscent of the late 1980s or early 1990s.
