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 0Insufficient data
20-40 16Insufficient data

80-100 You are here42+9.7% +8.2% 76.2% -18.7%

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 ≈ 36.68, at the 93.1th 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 意德士科技 do? Company profile

半導體業;半導體前段製程設備關鍵零組件、材料與維修服務 上櫃(櫃買中心 TPEx)

Overview

意德士科技股份有限公司成立於1999/07/15,總部位於台北市中山區民生東路二段170號4樓,股票代號7556,2020/10/30於櫃買中心上櫃掛牌,英文簡稱YEEDEX。公司代表人/董事長為闕聖哲,公開資訊與部分股市資料顯示總經理資料有闕聖哲與李順富不同版本,較新Goodinfo資料列李順富為總經理,故此項標示為需以公開資訊觀測站最新公司基本資料為準。實收資本額約新台幣2.73億元,已發行普通股約2,732萬股。營運主體包含意德士科技本身、100%轉投資製造工廠大鐿先端科技、49%轉投資誼特科技;2025年設立日本子公司TSS株式會社。2024年底意德士及大鐿員工約105人。主要股東/董監持股資料顯示董事長闕聖哲、法人董事毅曄股份有限公司及其代表人為重要持股者;2026年股東結構約為本國個人54%、本國法人42.1%、僑外投資3.58%、本國金融機構0.3%。公司2025年EPS 7.10元,董事會擬配發每股現金股利4.1元與股票股利0.5元;2026年第1季營收約2.13億元、EPS 2.52元,創高資訊來自法說會整理與股市資料。

Business

意德士定位為半導體前段製程設備耗材與精密零組件供應商,主要製造、銷售、維修與提供技術服務於半導體生產製程使用的精密零組件、材料與製程次系統。產品與服務涵蓋薄膜、蝕刻、擴散、黃光與廠務等製程領域;主要產品包括全氟化橡膠密封材/FFKM O-ring、DUPRA品牌全氟密封材代理、自有YEEDEX品牌全氟密封材、精密陶瓷零組件與材料、靜電吸盤與陶瓷加熱器再生製造、真空吸盤、客製化腔體內部零組件、高溫電漿熔射覆膜及製程次系統維修。公司產品強調抗電漿、耐高溫、抗腐蝕、高潔淨度,以提高先進製程設備穩定性與良率。營收結構方面,公開資料未見2026完整分項比例;過往公開說明書與法說資料顯示全氟橡膠密封材為最主要產品,約占營收最高比重,半導體零組件為主要收入來源,維修服務次之。商業模式為自製品牌、代理日本材料品牌、策略聯盟與售後市場並行:自製產品主要供應蝕刻與薄膜等高潔淨製程,代理日本大金DUPRA全氟密封材偏擴散製程;同時透過大鐿、誼特與日本TSS等關係企業支援製造、維修、OEM與海外客戶服務。主要客戶依公司法說會描述為全球最大晶圓代工公司、美商記憶體公司及美商半導體設備公司等,終端應用以先進邏輯製程、記憶體、HBM、AI/HPC、先進封裝與300mm晶圓廠擴產為主。

Outlook 2025–2028

2025至2028年展望偏向成長但受產能與客戶集中風險制約。成長動能包括:1. 先進製程節點推進,公司法說資料顯示YEEDEX全氟橡膠密封材已供貨N5、N3並於2025年開始供貨N2製程設備使用,2奈米與sub-2奈米製程對高潔淨、耐電漿、耐高溫耗材要求提升,有利密封材與腔體零組件需求。2. AI、HPC、HBM、先進邏輯與記憶體投資推升300mm晶圓廠及前段設備支出,公司引用SEMI資料指出2025、2026年全球半導體製造設備及晶圓製造設備市場仍成長,未來三年300mm晶圓廠投資預估持續成長。3. 先進封裝與CoWoS相關密封材開始交貨,AI伺服器相關密封材或模具樣品測試若通過,可能打開非傳統前段設備的新應用。4. 竹東二期新廠與技術中心已於2024年Q3動工,法說資料顯示預計2026年Q4開始投產;2026年法說整理則提到2026年完工、2027年上半年小量生產,若順利將舒緩產能瓶頸並支援美系OEM與海外業務。5. 日本熊本TSS子公司、德鑫半導體控股供應鏈聯盟及海外行銷平台,有助於切入日本、美國與在地化供應鏈需求。主要風險包括:產能滿載與新廠時程延誤、部分客戶與先進製程認證高度集中、半導體設備景氣循環、晶圓廠資本支出遞延、關稅與地緣政治、匯率、原料與日系合作夥伴供應穩定性、轉投資收益波動、可轉債轉換造成EPS稀釋,以及海外擴張初期成本增加。2027至2028的具體財務數字未見公司正式預測,僅能定性判斷為若N2、先進封裝、海外OEM與新廠產能如期放量,營運仍有中期成長空間。

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.
