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.

PE percentile bandSample days240-day avg returnMedianWin rateAvg excess (vs index)
0-20 400-0.7% -1.6% 46% -34%
20-40 277+24.7% +24.7% 56% -3.4%

80-100 You are here295+20.3% +1.6% 50.8% +2.2%

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 ≈ 60.96, at the 86.0th 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.

What does 鼎元 do? Company profile

光電業;LED、感測元件、功率元件與光通訊元件 台灣證券交易所上市

Overview

鼎元光電科技股份有限公司,股票代號2426,為台灣證券交易所上市普通股。公司成立於1987年4月4日,1998年11月25日上櫃,2000年9月11日轉上市;總部及登記地址為新竹科學園區苗栗縣竹南鎮科中路15號。董事長為蘇峯正,總經理為李榮寰,發言人為邱美玲。實收資本額新台幣3,006,222,520元,普通股發行股數300,622,252股,特別股發行股數為0。公司2025年12月法說資料揭露員工約910人,月產能約40億顆晶粒,生產據點包括台灣科中廠、台灣仁愛廠及中國武漢廠;管理系統認證包括ISO 9001、ISO 14001、IATF16949、QC080000、ISO 45001。主要法人股東與董監持股資料顯示富采控股股份有限公司持有約23,799張、約7.9%,並由蘇峰正、李存忠、李榮寰等法人代表參與董事會。公司早期由傅佩文、許敏川等業界人士於1987年集資創立,並與工研院工業材料研究所合作IR9400與LED單晶、磊晶製程放大及建廠計畫,屬台灣早期投入LED與感測光電元件的廠商。

Business

鼎元主要從事砷化鎵、紅外線、發光二極體、雷射二極體、光電晶體、光二極體、單晶、磊晶、晶粒之研發、製造與銷售,並兼營相關進出口貿易及光電系統研發製造銷售。2025年法說資料列示主要產品為:發光元件,包括可見光LED與紅外線LED;感測元件,包括Photo Diode與Photo Transistor;功率元件,包括TVS與Zener;光通訊元件,包括PINPD、MPD、VCSEL與APD。依2025年第3季營收產品結構,Si元件約71.5%、CS化合物半導體發光元件約24.6%、光通訊約3.6%、其他約0.4%;相較2023及2024年,Si元件比重提升、CS比重下滑,顯示營運重心由傳統LED逐步轉向感測、功率與利基光電元件。依客戶地區別,2025年第3季台灣約44%、中國大陸含香港約29%、亞洲其他地區約8%、美洲約14%、歐洲約4%;公司正積極拓展美洲、歐洲及日本市場。依終端應用別,2025年第3季仍以消費性電子為最大宗,約56%,另有工業、車用、醫療及光通訊應用;公司法說指出感測元件主要應用於穿戴及消費性產品,工控產品包括光源發射端與接收端元件,車用產品聚焦新能源車相關保護元件,光通訊則聚焦基礎建設與資料中心高附加價值元件。2025全年合併營收約新台幣23.36億元、年減約2.43%,EPS約-0.25元;2026年第1季營收545,147千元、毛利107,038千元、營業利益16,725千元、稅後淨利16,634千元、EPS 0.06元,顯示短期獲利已有改善但仍需觀察延續性。

Outlook 2025–2028

2025至2028年的核心觀察是產品組合能否由傳統LED與消費性電子,轉向感測、車用、工控及光通訊等毛利較佳且認證週期較長的應用。公司在2025年12月法說提出2026年四大營運重點:第一,感測元件與穿戴裝置維持穩健增長,與既有客戶密切合作並拓展歐美與日本市場;第二,新能源車滲透率提高,將提供更多樣化車載保護元件以因應需求;第三,工控用途光源發射端與接收端元件,隨高壓機種取得客戶承認與導入,預期延續成長並貢獻營收;第四,光通訊聚焦基礎建設與資料中心高附加價值元件,深化與歐美大廠合作。產業面,AI資料中心帶動800G、1.6T高速光模組、CPO與矽光子相關需求,可能使PINPD、APD、VCSEL、MPD、SWIR偵檢元件等光通訊產品比重在2026至2028年逐步上升;公司目前光通訊營收仍僅約個位數百分比,因此若導入成功,對產品組合與毛利率有槓桿效果,但若認證、良率、產能或客戶量產時程不如預期,成長兌現可能延後。主要風險包括:傳統LED與消費性電子價格競爭仍強;2025全年仍虧損,獲利修復尚未穩固;光通訊客戶多未公開具名,市場傳聞需與實際營收及毛利率驗證;中國大陸及台灣仍為主要客戶地區,需留意地緣政治、匯率、終端需求循環與新能源車景氣波動;若光通訊與車用產品擴張,還需投入研發、設備與品質系統,短期費用壓力可能上升。整體而言,2026至2028展望偏向轉型期,關鍵指標為光通訊占比、Si元件毛利率、工控與車用認證進度、歐美日客戶營收占比及單季EPS能否連續轉正。

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.
