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.

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 ≈ 60.98, at the 95.2th 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 協益 do? Company profile

電腦及週邊設備業 上櫃

Overview

協益電子股份有限公司成立於1969年1月8日，1998年7月20日上櫃，總部位於臺北市中正區館前路49號3樓，統一編號35229109。董事長為林欽淼，總經理為王化立。實收資本額約新台幣10.304億元，已發行普通股103,040,000股。公開資訊與券商資料顯示公司屬上櫃電腦及週邊設備業，股務代理為國票綜合證券，簽證會計師為勤業眾信聯合會計師事務所。員工規模資料來源不一：求職平台揭露約1,200至1,300人，三三企業交流會資料列示約1,186人，Investing.com 則列示3,017人；較保守採用『約1,200至1,300人以上』並在 notes 標示差異。主要股東與董監持股方面，2026年資料顯示董事及內部人持股約6%至8%區間，法人董事包含領航投資開發股份有限公司、台灣領航資產投資等；林欽淼為領航投資開發法人代表。

Business

協益定位為國際專業代工製造廠，能力涵蓋產品設計、電子設計、模具設計與製造、塑膠射出成型、SMT/PCBA 打件、產品加工、組裝、測試與出貨。主要產品包括電腦週邊、其他電子零組件與塑膠製品。2025年12月法說會揭露，2025年前三季產品別營收為：電腦週邊新台幣2,029,465仟元、占79.9%；其他電子零組件366,455仟元、占14.4%；塑膠製品143,567仟元、占5.7%；合計2,539,487仟元。2024年產品結構約為電腦週邊79%、其他電子零組件13%、塑膠製品8%。主要應用包含 AI 雲端運算平台器、高階伺服器用電路板、NAS 網路儲存伺服器、網通產品、車用觸控驅動板、汽車尾門/智慧門鎖與車用零件、魚群探測器、A4 印表機與 A3 影印機多色雷射碳粉匣、手持式掃描槍、警用隨身攝影機與秘錄器、電擊槍半成品、道路車牌辨識器、歐系醫療離心機塑件、釣具捲線器齒輪、精品飯店與郵輪給皂器等。商業模式以品牌客戶或系統廠委託代工為主，透過模具、塑膠射出、電子製造與終端組裝整合提高客製化與交期黏著度。MoneyDJ 資料指出主要客戶類型包括歐系車廠零件、美系印表機大廠、韓系家電大廠、美系網通大廠及台灣系統代工大廠；2017年重大訊息曾明確揭露 Lexmark International Inc. 為主要客戶之一。2024年銷售區域約為大陸35%、瑞士22%、美國16%、台灣11%、其他16%。

Outlook 2025–2028

2025至2028年展望以產品組合升級、供應鏈移轉與新廠布局為核心。公司2025年法說會指出，將持續投入自動化與智慧機械，強化高精密、高附加價值模具，運用數位化模流模擬與機構組立圖縮短產品設計到量產時程；同時與客戶合作投資高階高速 SMT 電路板加工設備，使產品由一般電路板升級至 AI 伺服器用高階電路板。成長動能包括：AI 伺服器與雲端運算帶動高階 PCBA/SMT 需求，NAS、網通、車用電子、警用影像設備、醫療塑件與精密模具延伸應用，及既有事務機/碳粉匣代工能力。供應鏈布局方面，公司表示因應地緣政治與產業競爭，採 China+1 與 Taiwan+1 策略整合各廠區資源，泰國廠已於2025年第2季開始建置，預計2026年正式營運；若順利量產，2026至2028年可望提高非中國產能彈性與接單能力。風險與挑戰包括：主要客戶集中與客戶交易模式變化、印表機耗材成熟市場成長有限、AI 伺服器高階板加工需要設備投資與良率爬坡、匯率波動與業外損益、台幣升值、地緣政治與關稅變動、同業 EMS/ODM 競爭、塑膠粒與電子零組件價格波動、海外新廠建置時程與稼動率不確定。2025年前三季營收年減10.9%，但毛利率由2024年前三季13.4%提升至15.6%，顯示產品組合改善有效；惟稅後淨利受業外損益影響大幅下滑，2025全年董事會通過合併營收3,354,983仟元、年減13.49%，EPS 0.44元，短期獲利仍需觀察泰國廠、AI 伺服器高階板與新客戶貢獻。

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.
