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 ≈ 38.55, at the 96.5th 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 閎康 do? Company profile

其他電子業;半導體檢測分析服務 上櫃(櫃買中心)

Overview

閎康科技股份有限公司,英文簡稱 MA-tek,成立於 2002/05/14,2009/08/18 上櫃,為普通股營運公司。總部/登記地址為新竹縣竹北市台元街26-2號1F,官網列聯絡地址亦含新竹科學園區力行一路1號1A3。主要營業項目為檢測分析服務。董事長為謝詠芬,公開股市資料顯示總經理為施韋;但 2024 年報董事/經理人章節曾揭露董事長兼總經理安排,管理職稱可能隨年度資料更新而變動。資本額公開股市資料約新台幣6.93億元,Goodinfo 顯示近期資本額約新台幣6.94億元、已發行普通股約6,936.9988萬股;不同資料日股本略有差異。2024 年報揭露 2024 年合併營收新台幣51.10392億元、稅後淨利6.88123億元、EPS 10.39元;2026/04/15 法說簡報揭露 2025 年營收新台幣55.45347億元,創歷史新高。員工規模方面,2024 年報揭露集團員工數 2024 年底為1,525人,2025/03/31 為1,547人。主要法人股東/董事席次相關法人包含亞克技術顧問股份有限公司、翔宣投資有限公司、昕明實業股份有限公司;年報揭露亞克技術顧問主要股東為謝詠芬48.28%、朱映慈17.24%、朱映親17.24%、朱映錫17.24%,翔宣投資主要股東為黃明順80%、張富華20%。集團據點含台灣、中國、日本與美國相關子公司/實驗室,2026 法說簡報稱亞洲有16座實驗室、全球客戶超過8,500家、每月處理超過24,000件檢測服務。

Business

閎康為第三方獨立檢測分析實驗室,主要服務半導體與高科技電子供應鏈的研發、製造、良率改善、品質與失效問題。核心業務包括材料分析(MA,例如試片製備、SEM、TEM、FIB、SIMS、XPS、光學干涉形貌等)、故障/失效分析(FA/EFA/PFA,例如去封裝、層次去除、X-ray、超音波、光子顯微鏡、OBIRCH、電性量測、故障定位)、可靠度分析/測試(RA,例如高低溫、溫濕度、HAST、溫度循環、機械衝擊、振動、鹽霧、壽命與偏壓測試),以及表面分析(SA)、化學分析(CA)、智慧財產權/第三方鑑定、競爭產品分析、逆向工程與技術諮詢。年報指出公司主要協助 IC 設計業分析產品設計問題,並以 IC 材料與結構分析能力服務晶圓製造、封裝測試等中下游產業,以提高良率與品質;產業鏈位置介於 IC 設計、光罩、晶圓製造、封裝、測試與終端產品之間。2025 年區域營收結構依 2026/04/15 法說簡報為:台灣36%(新台幣20.03612億元,年增6%)、中國39%(21.57017億元,年減6%)、日本13%(7.51199億元,年增68%)、美國9%(4.78339億元,年增45%)、其他3%(1.55180億元,年增3%)。2026Q1 區域營收為台灣32%、中國38%、日本18%、美國8%、其他4%,合併營收新台幣14.24420億元、年增15%。年報揭露公司無單一銷貨客戶占銷貨總額10%以上,表示客戶分散;法說簡報稱全球客戶超過8,500家。產品別營收精確占比未在已查證來源中完整揭露;可確認的是材料分析為核心競爭力,故障分析與可靠度分析為成長與垂直整合服務,矽光子相關業務 2025 年約占集團營收3.4%。商業模式主要為以高階儀器、工程師經驗、標準化流程、跨區實驗室與資料保密能力,向半導體、光電、車用、AI/HPC、先進封裝、矽光子等客戶收取檢測分析與專案服務收入。

Outlook 2025–2028

2025-2028 展望重點:一、先進製程與先進封裝。年報與法說均指出 AI/HPC、2奈米/GAA、A16/背面供電、3D IC、CoWoS/EMIB 等結構複雜化,將提高材料分析、故障分析、可靠度驗證需求;法說簡報強調公司具備 2nm、4nm、先進封裝相關實戰經驗。二、海外布局。2025 年日本與美國營收分別年增68%與45%,2026Q1 仍分別年增47%與41%;公司策略為深化日本名古屋、熊本、北海道布局,北海道 FA 實驗室規劃 2026Q3 ready,並以 overseas support by shipping 服務美國先進製程/先進封裝客戶。三、矽光子/CPO。2026 法說簡報揭露 2025 年矽光子營收占比約3.4%,2023-2025 年成長趨勢明顯;2026Q1 矽光子前十大客戶營收約新台幣1.91億元、年增51%,第一大客戶約0.82億元、年增85%;公司宣稱已覆蓋矽光子供應鏈檢測分析服務逾50%。矽光子目前仍處研發/試產階段,法說與市場整理資料均指大規模量產可能落在 2028-2030 年,因此 2025-2028 年主要動能偏向研發驗證、pilot run、良率提升與標準化分析流程,若 2028 開始進入量產前後,FA/RA/量產監控需求可能放大。四、可靠度與車用/功率半導體。年報指出 AI、車用、工業、5G/HPC、化合物半導體與功率元件將帶動可靠度測試與故障分析需求;2024-2025 已開發高電壓氮化鎵、SiC、矽光子模組、晶圓接合品質等分析技術。主要風險與挑戰包括:中國市場競標導致價格侵蝕、海外新實驗室初期固定成本與滲透時間拉長、先進設備資本支出高、人才養成與技術傳承難度、客戶機密與資安要求、矽光子量產時程不確定、地緣政治/出口管制/通膨與總體景氣波動、半導體客戶研發支出循環,以及同業在 MA/FA/RA 與跨國服務能力上的競爭。

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.
