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)
0-20 356+58.5% +55% 100% +40.1%
20-40 301+59.5% +55.1% 100% +38%

80-100 You are here905+48.8% +49.3% 80.2% +28%

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 ≈ 49.68, at the 95.8th 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.

光電業;特用化學材料、半導體材料、顯示器材料 上市

Overview

達興材料股份有限公司為普通股上市公司,股票代號5234,主要經營半導體產業及光電產業用化學材料之研究、設計、開發、製造及銷售。公司成立於2006年7月12日,由友達光電及長興材料合資成立,總部位於台中市西屯區中部科學園區科園一路15號,上市日期為2012年7月16日,實收資本額新台幣10.27159110億元。公司官網揭露董事長為林正一博士,2025年報揭露郭宗鑫於2026年2月24日轉任副董事長、莊鋒域於同日升任總經理;員工人數截至2026年1月約439人,研發人員占比超過50%,2025年報截至2026年2月28日員工合計438人。主要法人股東/董事席次相關持股包含長興材料工業股份有限公司約22.40%、康利投資股份有限公司約18.61%;康利投資為友達光電100%持有。林正一個人持股約2.24%。

Business

達興材料定位為特用化學材料研發、設計與製造公司,核心產品分為半導體材料、顯示器材料、關鍵原材料三大類。2025年度合併營收為新台幣46.29779億元,年增約12.4%。依2025年報營業比重,半導體材料營收7.73353億元、占16.70%,主要產品包含有機離型層、高純度溶劑、光阻剝離液、特用保護膠材、高選擇比銅蝕刻液、底部抗反射層剝離液及高純度高分子等,用於晶圓製程及封裝製程之直接永久材料及製程間接材料;顯示器材料營收37.50428億元、占81.01%,主要產品包含光阻材料、配向膜、銅蝕刻液、介電絕緣保護層、熱固化平坦保護層及濕式化學品等,用於LCD Array、Cell、Color Filter之直接永久材料及製程間接材料;關鍵原材料及其他營收1.05998億元、占2.29%,包含特用單體、鋰電池矽負極材料及原物料等,用於顯示器、半導體、綠能及化學相關應用產業之上游關鍵原材料。商業模式以自主研發、客製化材料設計、與國際材料大廠合作、與國際半導體大廠共同開發並進;顯示器端主要配合面板客戶技術升級與產品結構優化,半導體端切入先進製程、成熟製程與先進封裝,法說會揭露2025年半導體相關產品共25項,其中12項量產、13項驗證。2025年主要銷貨客戶中,友達光電銷貨金額20.27665億元、占全年銷貨淨額43.80%,其餘客戶合計56.20%;半導體客戶多以國際半導體客戶、國際材料大廠描述,公司未公開逐名揭露。

Outlook 2025–2028

2025年為公司半導體材料放量年,2025年報與2026年2月法說會均指出半導體材料營收7.73億元、占比16.7%,較2024年約3.72億元成長約108%,帶動毛利率與獲利提升;2025年合併營收46.30億元,毛利率40.6%,EPS 7.37元,現金股利6.5元。2026年公司展望為營運穩健擴張、成長動能加速,半導體及關鍵原材料將以自主研發、與國際材料大廠合作、與國際半導體大廠共同開發三種模式縮短新產品導入時程,2026年目標新增導入3至5項半導體產品;半導體產品方向涵蓋先進封裝Fan-out、2.5D、3DIC、WLP、PLP、CPO,以及晶圓前段/後段製程材料,並加速二奈米以下先進製程及先進封裝材料送樣驗證。顯示器材料方面,公司聚焦液晶配向膜PI、PSA PI、高感度/高塗速材料、低溫製程材料、Cu Stripper、FFS液晶配向膜PI與膽固醇液晶配向膜,策略為提升市占、維持品質穩定、優化成本與提高原料自製比例。2027至2028年可觀察的中期動能包括AI/HPC/資料中心帶動先進製程與先進封裝材料需求、半導體供應鏈在地化、國際客戶JDP共同開發模式擴大、Low Dk/Low Df低介電低損耗樹脂切入AI伺服器、低軌衛星與6G通訊應用,以及顯示器材料朝高解析、AR/VR、低溫節能與ESG材料升級。主要風險包含:顯示器材料仍占營收八成以上且面板產業景氣循環明顯;友達仍為單一最大客戶,2025年占銷貨43.80%,存在銷貨集中風險;半導體新材料驗證與量產時程具不確定性;國際大型化工/材料廠競爭激烈;匯率、原料價格、供應鏈穩定性與客戶製程變更均可能影響營收及毛利率。2027至2028具體財務數字公司未公開指引,本欄中期展望屬依公司2025年報、2026年法說與產業趨勢所作之研究判斷。

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.
