Branch inventory reconstruction

Accumulating holders Branches that accumulated shares during the window and still hold positive inventory; they are the absorbing side.

Distributing sellers Branches that built inventory earlier and have been selling it down; the remaining number estimates what has not cleared.

Net-short desks Trading-desk branches with negative inventory or net selling, often hedge, offsetting, or short-term flow. It is not automatically a bearish view.

Business

群光核心業務為電腦週邊與消費性視訊影像產品之研發、製造與銷售，集團產品主軸為鍵盤應用、影像相關產品、電源供應器與智慧家庭/網通相關產品。官方 ESG 公司介紹稱四大產品線為輸入裝置產品、攜帶式鍵盤模組、視訊影像產品、相機鏡頭模組；年報另將子公司群光電能之 PC/NB/伺服器/衛星及通訊電源、子公司展達通訊之網通產品納入集團營運脈絡。MoneyDJ 整理之 2024 年產品營收比重為鍵盤輸入裝置約 35%、電源供應器約 34%、影像產品約 26%、其他約 6%。主要產品包括 NB/DT/平板外接鍵盤、LED 背光鍵盤、觸控板與輸入裝置、網路攝影機、NB/AIO/TV/車用相機模組、運動攝影機、AI 視訊會議攝影機、智慧安防攝影機、PC/NB/遊戲機/印表機/伺服器/通訊/低軌衛星電源、LED 背光與車用照明模組、智慧建築與能源管理系統。商業模式以 ODM/OEM 製造、共同研發、全球即時交貨倉庫、VMI 與 One Stop Shopping 為主；主要市場為美洲、歐洲、亞洲與台灣，配銷方式包含內銷、外銷與間接外銷。年報揭露主要客戶為全球前十大電腦廠及其指定組裝廠、國內外知名電腦與系統廠；2024 年單一匿名甲客戶占合併銷貨 11.68%，公司未公開具名。群光自稱在 NB 鍵盤、影像模組及電源供應器等產品具全球領導地位。

Outlook 2025–2028

2025-2028 展望重點分四條主線。第一，AI PC 與商用換機潮：Windows 10 停止支援、Intel/AMD/NVIDIA 推動 AI PC 與新 GPU、企業端換機需求，將推升高階 NB、商用機種、電競機種及 LED 背光鍵盤、Copilot 鍵、觸控板與高畫素/多感測器相機模組滲透率，帶動 ASP 與毛利結構改善。年報引述 AI PC 出貨由 2024 年 4,400 萬台成長至 2025 年 1.03 億台，並提及 2027 年 AI PC 占整體 PC 比重可望達 60%；此類數字屬研究機構與公司引用之產業預估。第二，Edge AI 影像與智慧安防/視訊會議：2026 年新聞指出群光將擴大 Edge AI Vision Solution，結合 Edge AI 與視覺語言模型，應用於智慧安防、車隊管理、智慧工廠、智慧醫療、戶外休閒與視訊會議，影像產品經產品組合調整後被公司視為 2026 年成長引擎。第三，電源與 AI 基礎建設：子公司群光電能受惠大瓦特數 NB 電源、AI 伺服器/HPC 電源、衛星與通訊電源、智慧低碳整合平台；年報稱 3KW 到 5KW AI 伺服器單顆或系統級產品線已到位，AI 伺服器電源與高階通訊電源將是 2025-2028 的重要成長方向。第四，產能與地緣政治：公司製造基地由中國延伸至泰國，2024 年泰國廠營收占集團約 20% 以上，新聞稱 2025 年規劃提升至 25%-30%，可降低關稅與地緣政治風險並提供客戶彈性製造。主要風險包括 PC/NB 終端需求不如預期、記憶體漲價與缺料壓抑出貨、價格競爭與陸商技術追趕、匯率與原物料波動、單一匿名大客戶占比接近 12%、AI PC/Edge AI/AI 伺服器滲透速度低於預期、泰國擴產效率與成本、關稅與供應鏈重組不確定性。2026 年公開新聞指出 2025 年營收年減約 5.7%，法人預期 2026 年營收高個位數成長、挑戰重返千億元；此為法人或媒體預估，非公司保證財測。

Excess return is measured against the TAIEX total-return index (dividends included).
Valuation regime and percentile stats use an expanding own-history window (no future data).
Revenue-signal event dates align to the first trading day after the filing deadline, avoiding look-ahead.
Event samples may overlap in time; stats describe historical distribution only and are less reliable when samples are few.
