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)
0-20 933+8.6% +2% 52.6% -14.5%
20-40 524+22.9% +19.8% 82.6% +9%

80-100 108+6.7% +18.6% 55.6% +7.7%

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 ≈ 19.53, at the 79.4th percentile of its own history (60-80 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.

Business

公司定位為不鏽鋼管配件與潔淨級氣體管路材料供應商,採雙品牌與雙事業部模式,主要產品為潔淨級管配件、廠務服務、不鏽鋼焊接管配件及其他產品服務。2024年合併營收1,404,705千元,營收結構為潔淨級管配件466,057千元、占33.18%;廠務服務450,760千元、占32.09%;不鏽鋼焊接管配件416,158千元、占29.63%;其他71,730千元、占5.10%。潔淨級產品包括Pipe、Fittings、VCR、Micro Fitting、Lok Type Fitting、CGA Fitting、潔淨閥等,主要用於半導體、光電、太陽能、LED與其他高潔淨環境之氣體或流體輸送;年報指出潔淨級管材約九成應用於半導體及光電相關產業。化工級產品包括有縫與無縫不鏽鋼焊接管配件、彎頭、三通、漸縮管、管帽、SU薄壁管件與管節等,應用於石化、化工、造船、食品、造紙、發電、醫療等工業配管。大川研科技提供流體系統工程、檢測、氣體供應系統、TGM/TCGM鋼瓶管理、人力服務、特殊氣體與設備代理等,補強大甲在高科技廠廠務端的整合服務。2024年銷售地區以內銷為70.01%,亞洲外銷13.97%,美洲12.80%,歐洲0.07%,其他3.15%。主要商業模式包括自有品牌製造、工程公司與庫存商供貨、半導體與光電建廠案材料供應、氣體公司與設備商客製零組件、日美市場外銷與部分歐美日管件大廠代工。

Outlook 2025–2028

2025至2028年成長動能主要來自四條線:第一,AI、高效能運算與先進製程推動台積電等半導體廠在台灣、美國、日本、德國持續建廠或擴產,帶動潔淨級管材、微接頭、閥件、VMB/VMP、Gas Box與廠務服務需求。第二,半導體供應鏈國產化與建廠成本壓力提高,有利本土潔淨級管路材料取代部分日系與美系產品;公司具精密加工、電解拋光、潔淨清洗、檢測與完整管、管件、Component產品線,年報稱為國內潔淨級本土龍頭。第三,產品與服務擴張包括潔淨閥、膜片閥、Bellows閥、Regulator、VMB/P與Gas Box組裝、潔淨儲藥鋼瓶、低蒸氣壓前驅物氣化供應系統、數據中心冷卻系統管材、日本氫能儲運特殊管件,以及大川研從材料、配管、檢測延伸到氣體系統設計、設備選購、安裝、測試與維運。第四,美國反傾銷稅不再續課、海運波動因素降低,有助化工級產品拓展美國市場;日本重視品質與穩定供貨,JIS與SU管件認證有助維持長期客戶。主要風險包括:石化與化工級市場成熟、成長趨緩且低價競爭激烈;中國與東南亞產能過剩壓低價格;台灣環保法規與勞力成本提高;不鏽鋼原料價格、匯率與日圓弱勢影響毛利;潔淨級產品客戶驗證期長且高階市場仍受日系品牌主導;半導體、光電與太陽能景氣循環及建廠時程變化會放大訂單波動;中國半導體受美國管制與本土化影響,安徽大甲接單仍具不確定性。2027至2028年具體財務數字公司未公開,以上為依公司年報、法說與公開新聞推估之產業展望。

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.
