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.

Valuation regime and subsequent returns

Each day's PE is converted to its own-history percentile (as of that day), then we look at adjusted-close returns over the next 240 trading days by valuation regime.

Percentiles use an expanding own-history window (no look-ahead); forward return is 240 trading days on adjusted close. Sample days overlap; distribution is indicative only.

Current PE ≈ 32.11, at the 99.8th percentile of its own history (80-100 band).

Valuation × momentum historical grid

Every day in its own history is bucketed by valuation tercile (own-history PE) and 60-day momentum sign into six cells; we show adjusted-close returns over the next 120 trading days per cell.

光電業／精密光學元件／手機鏡頭 上市（台灣證券交易所）

Overview

Business

大立光為全球精密光學塑膠鏡頭主要供應商，核心商業模式為以自有光學設計、模具、製程、檢測與自動化能力，向智慧型手機、消費性電子、車用、AR/VR、IoT、醫療、光通訊等客戶供應高精度鏡頭、鏡片、光學元件與相關模組。2024年報揭露業務係各式光學鏡頭模組與光電零組件之研發、設計、生產、銷售及售後技術服務；產品涵蓋筆電、智慧型手機、3D結構光、ToF、屏下光學指紋、空拍機、平板、IP Camera、智慧電視、AR/VR、IoT、穿戴、虹膜辨識、醫療儀器、汽車鏡頭與鏡片等。2024年營收結構中，光學元件新台幣590.52億元、占99.32%，其他4.05億元、占0.68%；銷售地區以亞洲為主，占95.66%，美洲4.32%，歐洲0.02%。2024年報揭露前兩大銷貨客戶以代號呈現，653021於2024年占銷貨30%，632019占12%，2025年第一季653021占36%、632019占14%、643006占10%，顯示客戶集中度高但公司未公開實名。官網產品線除手機鏡頭外，也列示音圈馬達、影像鏡頭模組、睡眠健康監測、車用鏡頭、隱形眼鏡、碳化矽晶體、鈮酸鈦負極材料、光纖雷射及太空通訊、CPO應用；CPO應用產品包含稜鏡微透鏡陣列與1D/2D光纖陣列。

Outlook 2025–2028

2025至2028年展望可分為既有手機鏡頭升級與新光學應用兩條主線。手機鏡頭方面，2024年報指出年度產銷重心仍集中於手機相機鏡頭，研發方向包含汽車用影像鏡頭、醫療用鏡頭、安全監控、大光圈／大廣角、全幅對焦、虹膜辨識、運動相機、空拍機、小pixel size、低Z height、ToF、屏下光學指紋、自由曲面、AR/VR、IoT、可變光圈、筆電窄邊框、模造玻璃與分群folded tele等。2026年1月與4月法說相關報導指出，可變光圈鏡頭預計2026年第三季出貨，折疊機鏡頭則規劃較晚出貨；2026年第一季出貨以1000萬畫素以上產品為主，顯示高階鏡頭規格仍是短中期主軸。新成長動能方面，公司官網已列出CPO應用產品，2026年6月股東會與媒體報導指出大立光正推進FAU／CPO相關自動化試產線，預計2026年9月前完成或亮相，對位精度目標達0.3微米以下，若客戶認證順利，後續小量產可能需半年至一年；此領域若量產成功，2027至2028年有機會成為手機鏡頭以外的新成長曲線。產能與製程方面，公司長期策略包括持續投資自動化設備、擴增產能、降低不良率與生產成本，並以台灣總部作為主控據點。主要風險包括智慧型手機成熟與換機周期拉長、低階鏡頭價格競爭、客戶集中與大客戶議價、手機鏡頭出貨占比過高、半導體與記憶體等零組件成本排擠手機品牌鏡頭升級預算、原物料價格由國際大廠掌控、匯率波動、CPO／FAU新產品驗證與量產良率不確定，以及中國大陸與國際光學同業追趕。

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.
