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.

Historical evidence

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.

80-100 577+3.4% +6.4% 57.7% -14.5%

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 ≈ 34.44, at the 78.6th percentile of its own history (60-80 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.

Business

雷笛克主要從事二次光學透鏡、車載二次光學透鏡、精密塑膠件與光電模組產品之研發、生產與銷售。二次光學透鏡是搭配 LED 光源調整光型、配光、均勻度與光效的光學控制元件,應用於建築照明、商業照明、路燈、車燈、醫療、舞台、園藝、監視器、戶外看板等。2024年產品營收結構為:透鏡新台幣841,286仟元、占55%;精密塑膠件開發及製造530,367仟元、占34%;其他172,640仟元、占11%;合計1,544,293仟元。2025年12月營收公告顯示2025全年合併營收1,317,924仟元,年減14.66%,主因子公司群宏光電AI散熱產品出貨不如預期;但公司表示母公司專業照明透鏡與車用透鏡兩大產品線仍年增逾10%。法說會揭露2025年前三季車用產品營收464,558仟元,占同期營收48.14%,高於2024年全年車用占比32.00%;累計開發車用模具數至2025年前三季達931套。公司商業模式以客製化光學設計、模具開發、射出成型量產與光機電控整合為核心,具少量多樣、高度客製、驗證期長的特性;前十大客戶營收比重低於30%,最大客戶低於7%,累計客戶數超過5,700家。主要終端應用包括專業照明、車用照明,以及透過品輝、群宏等子公司切入精密塑膠、光電模組、AI/3C/IPC/電競與伺服器散熱相關應用。

Outlook 2025–2028

2025年為營運調整年,全年營收年減14.66%,前三季仍呈淨損,主因包含中美貿易情勢、專業照明與車用市場壓力、中國車用市場價格競爭,以及子公司AI散熱產品出貨不如預期。不過2025年第三季毛利率已由上半年約22%提升至約25%,公司表示自2024年下半年起檢視接單內容、調整產銷結構,提升獲利能力。2026至2028年主要成長動能預估來自車用透鏡放量、高附加價值車燈產品、專業照明客戶結構優化,以及子公司精密塑膠件、光電模組與AI散熱相關業務的客戶拓展。車用方面,LED導入日行燈、尾燈、頭燈、霧燈、邊條燈、氣氛燈等車輛部件,且車燈零件驗證期長、可靠度要求高、供應鏈黏著度高,對已通過品質系統與客戶驗證者較有利;公司目前車用出貨以頭燈與霧燈約60%至65%為主,將持續鎖定高光型要求、高附加價值產品。產能與製程方面,公司近三年擴建揚州二期廠並採購大噸數注塑機,資本支出約1,100萬美元;2025年前三季導入全自動注塑機與無塵室,並調整揚州與東莞產線配置。產業趨勢方面,LED照明滲透率提升、車用LED照明市場成長、節能政策與人因照明需求,均有利於二次光學透鏡需求;年報引用Mordor Intelligence估計全球汽車LED照明市場2025至2030年複合成長率約9.02%。風險與挑戰包括:中國車用價格競爭、客戶拉貨與專案量產時程不確定、AI散熱子公司訂單能見度不足、PC/PMMA等塑膠粒子原料價格波動、匯率與關稅、車用驗證週期長、固定資產與模具投資折舊壓力、以及公司仍需證明營收回升能轉化為穩定獲利。2027至2028展望缺乏公司明確量化財測,以上為依公司法說會、年報與產業趨勢所作之研究推估。

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.
