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 You are here0Insufficient data
20-40 147+25.9% +22.8% 100% +10.4%

60-80 155+123.5% +122.5% 98.7% -72.9%
80-100 27Insufficient data

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 ≈ 4.33, at the 2.2th percentile of its own history (0-20 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

三一東林原核心業務為電光源驅動元件,生產、研發與銷售電子式安定器、電子式變壓器、LED電子式驅動器,產品應用於鹵素燈、螢光燈、汞燈、複金屬燈、高壓鈉燈、LED燈、UV燈管電源、智慧照明、軌道燈、高端建築照明、精品店舖、五星級旅館、博物館與照明工程。公司強調調光、低頻閃、節律照明、無線藍牙智能照明、IoT照明、色溫控制與各國安規認證,德國 HEP GmbH負責歐洲銷售服務與研發協作,珠海威森電子為電子驅動器生產工廠。2020年後公司跨入汽車科技事業,代理 BRABUS、STARTECH、TECHART、NOVITEC、ABT、KLASSEN、HOFELE、9FF、MORGAN MOTOR、The Little Car Company、Vossen、Racechip、MATE BIKE等高端汽車/改裝/電輔車品牌,提供改裝零件、成車銷售、安裝、調校、維修、保固與客製化服務;永續報告書稱其部分台灣總代理獨家經銷市場占有率為100%。2024年營收結構為LED電子產品216,773仟元、占55.64%;成車銷售118,149仟元、占30.32%;其他54,708仟元、占14.04%。2024年地區別營收為亞洲226,257仟元、歐洲155,473仟元、其他7,900仟元。商業模式為電子產品研發製造銷售加海外倉儲/服務,以及高端汽車品牌代理、進口、展示、客製化改裝與售後服務。主要終端客戶未逐名揭露,類型包括照明燈具廠、照明工程商、商業/建築空間業主、精品店舖、旅館、博物館、高端車主、收藏家與汽車改裝愛好者。

Outlook 2025–2028

2025至2028年展望可分為三條主線。第一,電子科技事業受惠節能減碳、低碳產品、智慧建築、健康照明、低頻閃、色溫/節律照明、無線控制與IoT照明需求,公司已布局Ultra-dim低調光、CCT/RGB色溫控制、無線智能驅動、AI智慧照明系統與軌道燈具;若歐洲與亞洲照明需求回溫、低碳產品與安規認證優勢轉為訂單,LED驅動器本業有機會改善。第二,汽車科技事業以高端客製化、限量車、BRABUS/MORGAN/ABT等品牌代理、台北亞洲總部與展示服務網絡帶動高資產客戶黏著度;2026年新聞指出公司啟動AI洗車園區、海外不動產、AI照明系統三大成長引擎,並以本業轉盈、營運持續成長為目標。第三,多角化與高端生活平台策略可能帶來高單價但不連續的收入,例如限量經典車/改裝車成交、海外不動產與高端服務。主要風險包括:2024年營收大幅年減且仍虧損,營運轉型成效仍需連續財報驗證;高端車銷售具單筆訂單認列與交車時點波動,營收可見度低;改裝車受景氣、高端消費、匯率、進口法規、排放/噪音/驗車規範影響;LED驅動器面臨價格競爭、客戶拉貨波動、歐洲景氣與中國/台灣電子供應鏈競爭;低碳法規可能提高採購、認證、碳盤查與供應商管理成本;供應鏈若受極端氣候、運輸或零組件交期影響,可能造成生產與交付延誤。2027至2028具體量化財測未見公司公開揭露,本段屬根據公司公開策略、永續報告書與新聞所作之研究推估。

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.
