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 You are here344+77.1% +99.3% 75% +56.7%
20-40 632+13% -6.1% 44.8% -5.5%

80-100 451+38.4% -5.4% 37.3% +17%

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 ≈ 12.7, at the 20.0th percentile of its own history (0-20 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

國統是台灣少數同時具備大口徑混凝土管、鋼管、延性鑄鐵管等管材製造與管線承裝能力的水資源工程廠商,商業模式包含管材/管件製造銷售、工程承攬、海水淡化與污水/再生水處理廠興建及營運。2024年營收結構為工程承攬75.29%、商品銷售16.06%、海淡水及污水處理4.87%、其他3.78%;2024年合併營收5,245,526千元,年增26.94%,EPS 3.37元。主要產品與服務包括PCCP鋼襯預力混凝土管、PSCP無鋼襯預力混凝土管、RCCP、RCP、JCP推進用混凝土管、DIP延性鑄鐵管與管件、SP塗覆裝鋼管、WSP大口徑推進鋼管、SPE聚乙烯內外被覆鋼管、可撓管、鋼製接頭、海水淡化、淨水廠、水資源回收中心、污水下水道與管線工程。2024年銷售全為內銷,北區36.71%、中區25.21%、南區38.08%。主要客戶集中在公共水資源建設機關,2024年銷貨占比逾10%的客戶為經濟部水利署南區水資源局33.85%、台灣自來水18.05%、國家科學及技術委員會南部科學園區管理局13.10%、苗栗縣政府11.13%。公司亦透過子公司/關係企業參與海水淡化、自來水配管、污水下水道系統興建營運與投資業務,包括西嶼海水淡化、國洋環境科技、國創工程等。

Outlook 2025–2028

2025至2028年主要成長動能來自政府水資源韌性建設、海水淡化、再生水、污水下水道、區域調度幹管與大型供水改善工程。公司2024年取得臺南海水淡化廠統包工程第一期暨代操作維護案,官方工程資訊顯示決標金額20,964,752千元,2024年6月27日開工、預定2029年4月11日完工,第1期設計產水能力每日10萬立方公尺,並規劃第1期營運產水5年後再增加每日10萬立方公尺;此案可支撐2025至2028工程收入與後續長期維運收入。公司2024年年報指出,2024年集團取得管材及工程標案含委託代操作維護總金額含稅約207億元,且2025年度營運重點包括輸配水管線及水利設施工程、海水淡化廠投資興建營運、鄉鎮都市下水管道、水資源回收中心、DIP及SP管件銷售、再生水廠工程及營運、前瞻基礎建設中的水庫整治與供水改善、淨水廠工程規劃設計施工。產業面,極端氣候、半導體與科學園區用水需求、再生水與海淡廠布建、政府強韌水利/珍珠串相關計畫均有利接案;2026年5月累計營收約27.79億元,年增約19.8%,顯示工程認列仍在推進。主要風險包括公共工程預算與發包時程延後、統包工程工期長且付款條件較嚴、鋼材/水泥/砂石等原物料價格波動、路權與民眾協調、天候影響施工、工程成本估計與毛利率波動、長期維運案的履約與能耗成本、環保法規與職安要求、客戶集中於公部門導致政策與驗收節奏影響營收認列。2027至2028展望屬依既有標案進度與政策延伸的推估,尚無公司逐年財測。

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.
