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

佰鴻主要經營光電零組件，核心產品為 LED 元件與相關產品，分為可見光與不可見光兩大類。可見光產品包括 Lamp、Display、SMD、PLCC、LED Light Bar Assembly、照明燈具；不可見光產品包括 Infrared、Motor Assembly、Sensor Assembly。主要用途涵蓋電腦週邊、通訊、電器、消防、醫美器材、照明、汽車電子、看板、工業自動控制、家電產品、電機產品、安防與遙控器等。2025 年年報揭露 114 年度營業比重為 LED 相關產品銷售 89%、照明專案工程 9%、其他 2%；2025 年合併營收淨額新台幣 1,141,998 千元，較 2024 年 1,177,756 千元減少約 3%，稅後合併淨利 185,854 千元，歸屬母公司稅後淨利 188,618 千元，EPS 1.09 元。2025 年銷售地區為中國含香港 46%、美國 17%、韓國 17%、台灣 14%、其他 6%。商業模式以 LED 封裝、模組、客製化光電元件與照明工程為主，透過上游晶片、支架、PCB 等原料整合與自動化製程，供應消費性電子、3C、家電、安防、工控、車用、航太、照明及工程標案客戶。年報揭露 2025 年曾占銷貨總額 10% 以上客戶包括 AB 18%、K 公司 13%，但未揭露完整客戶名稱；此表示銷售仍有部分關鍵客戶集中但公司年報稱進貨或銷貨集中風險為無此情形。

Outlook 2025–2028

2025 年公司營運大致持平，受全球政經動盪、消費市場景氣不佳、通膨及地緣政治影響，營收年減約 3%，但受惠精實管理、成本控制與高附加價值產品比重提升，毛利與獲利維持穩定。2026 年公司年報揭露營業計畫為既有量產應用產品持續優化，包含智能家居、安防安控、航空及運輸電子、電腦相關、感應感測、照明等，並提供客製化與差異化方案；公司預估 2026 年整體較 2025 年持平並朝 1% 至 5% 小幅回升，但公司亦於重大訊息澄清該敘述取自年報，非最新財務預測。2026 年 1 至 5 月累計營收約新台幣 527,752 千元，年增約 18.9%，短期顯示需求較 2025 年同期回溫。2026 年研發方向包括特殊規格、多顆晶片多波長 LED，應用於醫療、車用與航太；光繼電器 Photo Relay；UV-C LED；ATM 模組；航太新專案樣品認證；LED 搭配 IC、多晶片多波長、Receiver module、RGBW、Photo coupler 等封裝產品；智慧化路燈及智慧系統整合。2027 至 2028 年公司未發布可量化財測，較合理的中期展望是：若客製化不可見光、感測、車用、航太、醫療、智慧照明與工程標案推進順利，營收與毛利率有機會受惠高附加價值產品比重提升；但 LED 封裝產業仍面臨中國廠商低價競爭、客戶認證期長、終端消費電子景氣循環、匯率波動、通膨與生產基地成本上升等風險。公司因應策略為提高自動化比重、製程改善、精實管理、開發差異化與高品質產品，並透過上中下游整合維持原料供應穩定。

Method and limitations

  • All returns use adjusted close (etl:adj_close), already adjusted for dividends and splits.
  • 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.
