UBS:CTAs持股逼近極限 買入空間有限




UBS指CTAs股市持倉接近極限 買入空間有限

根據瑞銀(UBS)的最新報告,商品交易顧問(CTAs)目前在股票市場的持倉已接近最大長倉水平,未來進一步買入的空間相當有限。

由Nicolas Le Roux領軍的策略團隊指出:「CTAs現時接近股票的最大多頭持倉,短期內傾向維持這個狀態。即使在非常看多的情況下,他們的買入空間也非常有限。相反,他們還有賣出的空間,但由於基數效應強勁,資金流出幅度應會受限。」

瑞銀估計,在一個負向兩標準差的極端情況下,CTAs或會沽出約550億美元的全球股指,該數字相較於歷史上的回調來說仍屬偏低。

瑞銀的模型顯示,CTAs的股票持倉大幅增加,近期資金流入令他們更深陷多頭區域。

短期指數動能仍偏多 多個市場被看好與看淡

瑞銀亦指出,短期交易中,指數動能仍然看好,包括納斯達克100、標普500、瑞典OMX、台灣加權指數(TWSE)及馬來西亞FBMKLCI。

同時,報告亦提出一些逆向交易機會,例如瑞士SMI、巴西Ibovespa、荷蘭AEX及印度Nifty均被看多;而挪威OBX、南非TOP40、德國DAX、墨西哥MEXBOL及香港恒生中國企業指數(HSCEI)則出現看淡信號。

債券方面:美國長倉對歐洲短倉仍為主流策略

在債券市場,CTAs持續建立顯著的「多美國債券、空歐洲債券」的相對價值頭寸。瑞銀稱,CTAs仍偏向支付利率,尤其是在債券曲線的長端,對歐盟、法國、日本及加拿大債券的空頭持倉屬其高信念交易。

外匯及大宗商品動態

外匯方面,7月份美元反彈令CTAs減少美元持倉,但隨後又回補約100億美元。策略師表示:「我們不預期CTAs的外匯資金流會明顯增加,僅見部分G10貨幣(英鎊及日圓)買入,與部分新興市場貨幣的賣出相抵。」

大宗商品市場則因能源價格在區間內波動,令CTAs的交易表現「頗為痛苦」,目前在能源板塊保持中性。貴金屬則仍是「亮點」,CTAs無意減持;策略師建議「或許是時候獲利了結,並開始回補農產品部位」。

評論與洞察

UBS的分析揭示出CTAs在股票市場的多頭持倉已接近極限,這反映出市場對未來股市上升空間的謹慎態度。CTAs作為重要的程式交易者,其持倉狀況往往能反映市場趨勢的強弱,當他們「買入空間有限」時,意味著股市短期內可能缺乏強有力的資金推動,存在調整風險。

同時,CTAs在債券市場持續做多美國、做空歐洲的策略,反映了對美國經濟及貨幣政策的相對看好,與歐洲面臨的經濟挑戰形成鮮明對比。這種跨市場的套利策略,亦突顯了全球資金流向的結構性變化。

在外匯及大宗商品市場,CTAs的動作較為謹慎,尤其是在能源板塊的中性持倉,顯示對未來能源價格波動的不確定性。貴金屬的持續看好,則可能反映避險需求尚存。而農產品的回補信號,可能暗示著供應面或需求面有新的變化值得關注。

整體而言,CTAs的持倉動向提供了一個觀察市場風險偏好及資金流向的重要窗口。投資者應密切留意這些大型交易者的動作,特別是在全球經濟仍存在諸多不確定因素的背景下,CTAs的策略調整可能預示著市場的轉折點。對香港投資者而言,特別要留意港股(如HSCEI)被CTAs看淡的信號,或許暗示本地市場短期面臨較大壓力,需要謹慎部署。

一隻在香港茶餐廳喝奶茶的貓 Create a hyper-realistic 8K close-up body portrait of a male model, using the uploaded photo as the exact facial reference. Maintain 100% accuracy of the facial features — do not alter or modify any aspect of the face. Render the skin texture, lighting, and overall composition with photo-realistic detail, ensuring lifelike color tones and natural depth of field. A man with his original hairstyle, he is standing confidently, hands in his pockets, looking directly at the camera. He is wearing a simple, light beige crew-neck sweater and dark trousers.
He is positioned between two decorated Christmas trees. The tree to his left is adorned with gold and white ornaments and warm lights, with wrapped red and gold gifts visible at its base. The tree to his right is decorated with red and gold ornaments. The background shows a warm, indoor setting, likely a home, with soft lighting, creating a festive and inviting atmosphere. The overall impression is one of relaxed holiday cheer. Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a striking, ultra-sharp black and white studio portrait of a young woman with a powerful, direct gaze. She is seated gracefully on a seamless bright white floor, her legs crossed in a stylized, almost sculptural pose, with one knee raised and her hands clasped firmly over it. Her posture exudes a blend of strength and quiet contemplation. Her long, sleek, dark brown hair is meticulously parted down the middle, falling evenly over her shoulders, framing her face with elegant precision. Her makeup is refined and impactful, featuring intensely defined eyes with dark eyeliner, subtle shading, and prominent, well-groomed eyebrows. Her lips are natural, complementing her smooth, matte complexion. She is dressed in a simple, form-fitting black long-sleeved bodysuit, which accentuates the natural contours of her body without distraction. There are no accessories, maintaining a pure and minimalist aesthetic. *** The lighting is soft, even, and highly diffused, creating subtle, sculptural shadows that define her form and facial features without any harshness. The seamless pure white background provides an expansive, ethereal setting, isolating the subject and enhancing the monochromatic palette. The composition is a perfectly balanced medium full shot, centering the model and emphasizing the strong, symmetrical lines of her pose. The image is rendered with exquisite detail and clarity, from the individual strands of her hair to the subtle textures of her skin. The overall style is minimalist fine art portraiture, blending classic elegance with a contemporary edge, focusing on form, emotional depth, and timeless beauty.
