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 You are here263+59.5% +56.2% 99.6% +17.2%

80-100 146+28.3% +27.7% 83.6% +7.1%

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 ≈ 9.52, at the 6.5th 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.

What does 洋華 do? Company profile

光電業 台灣證券交易所上市

Overview

3622 對應證券為洋華光電股份有限公司普通股,簡稱洋華,英文簡稱 YFO,為台灣證券交易所上市公司,產業別為光電業。公司登記與投資人關係資料顯示成立日期為 2002 年 7 月 30 日,總部位於桃園市觀音區觀音工業區經建一路31號;董事長為白志強,總經理為許益川,發言人為何逢有。公司於 2008 年 3 月 28 日興櫃、2009 年 3 月 25 日掛牌上市。公開資料顯示實收資本額約新台幣 15.13 億元至 15.16 億元,已發行普通股約 151,327,600 股,無特別股。公司前身為大河隆機電股份有限公司,原本專注超高壓電力電纜附屬器材,2007 年 12 月與洋華光電合併並更名為洋華光電股份有限公司,形成機電與光電雙事業。員工規模方面,112 年度年報揭露員工人數 156 人;較新的 2024 永續報告書可查得揭露期間但本次未能可靠擷取總人數,因此未更新。主要股東依 112 年度年報與公開股權資料包括嵩益實業股份有限公司、合機電線電纜股份有限公司、章苗開發股份有限公司;2026 年 3 月董監持股資料顯示嵩益實業持股約 21.41%,合機電線電纜仍為法人董事與重要持股者。公司網站揭露主要業務為觸控面板與電線電纜器材。

Business

洋華目前為雙主軸營運:一、機電事業,主要產品為高壓交連 PE 電力電纜附屬器材,包括 69kV、161kV 等級電纜終端匣、接續匣、保護裝置等,並與日本古河電工有技術合作歷史;公司自述其超高壓電力電纜附屬器材具自製能力,且為國內少數通過台灣電力公司驗證合格的廠商。該業務主要服務電力電纜廠商與台灣電力公司相關工程需求,近年受惠台電強韌電網計畫、變電站與饋線建設、綠能併網需求,已成為營收與獲利主力。二、光電事業,主要產品包含投射式電容觸控面板、電阻式觸控面板、強化玻璃與表面處理、電子紙顯示器前導光貼合、Monitor/整機組裝與貼合服務。公司產品應用從早期智慧型手機、PND 等消費電子,轉向工控、醫療、車載、軍規、零售、交通、博弈、POS、運動器材、電子紙與顯示器整機等利基市場。營收結構方面,2023 年外部資料顯示電力電纜配件約 76%、觸控面板約 24%;2024 年多家券商與資訊服務資料顯示電線電纜器材約 81.50%、觸控面板約 18.50%;2025 年法說摘要則稱機電事業約 80%、光電事業約 20%。商業模式上,機電業務以通過規範驗證、配合電纜廠與台電標案工程供貨為主,重視可靠度、交期、良率與成本控制;光電業務則以客製化中小尺寸或利基型面板、貼合與模組整合服務為主,近年透過越南產能承接去中國化供應鏈需求。

Outlook 2025–2028

2025 至 2028 年展望可分為穩定基礎與轉型成長兩部分。機電事業是主要支撐:台電強韌電網計畫屬十年期大型投資,公開報導提及總預算約 5,600 億元,其中與洋華相關者為分散與強固工程;2025 年法說報導指出分散工程約 4,379 億元、至 2025 年約執行五成,後續仍有四成多逐年執行,因此 2026 至後續數年機電部門預期維持平穩、接近近年水準。機電產品中,161kV 終端匣與接續匣仍為主力;公司亦朝 345kV 附屬器材產線布局,2024 年報導稱國內 345kV 附屬器材目前多仰賴進口,洋華正與日商合作並嘗試切入關鍵零組件,若未來取得技術合作或驗證,可能提高產品規格與附加價值,但此仍屬中長期機會且量產時程與認證結果未完全確認。光電事業的成長動能來自垂直整合與新品:公司規劃從觸控面板延伸至蓋板玻璃、TFT LCD、電子紙、PMOLED 貼合與整機組裝;2025 年法說與新聞稱 2026 年光電部門因監視器整機組裝與中大尺寸電子紙模組量產,營收可望小幅成長,且越南設廠多年,有利承接中美貿易摩擦與去中國化供應鏈轉單。2025 年前三季公司 EPS 已超過 2024 全年,惟部分獲利來自黃金存摺評價利益等業外收益,不能視為完全可重複。本業風險包括:台電標案進度與預算執行節奏波動、工程驗收與交期、原材料與外包加工成本、345kV 技術移轉或認證不如預期、機電業務客戶集中度偏高、光電觸控面板受 on-cell/in-cell 技術與消費電子需求疲弱壓抑、越南產能利用率與新客戶導入不確定、匯率與關稅政策變動、業外收益波動造成 EPS 品質落差。整體判斷,2025-2028 年機電業務較可能提供穩定現金流,光電則是小幅復甦與轉型選擇權;高成長情境需仰賴 345kV 產品、電子紙/Monitor 組裝與去中國化訂單實際放量。
