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.

What does 三洋實業 do? Company profile

建材營造業／營建工程業 上市（台灣證券交易所）

Overview

三洋實業股份有限公司，前身為三洋紡織纖維股份有限公司，成立於1968年10月7日，股票於2000年9月11日上市，2021年前後由紡織業轉型為營建工程業。公司總部位於高雄市大社區嘉保路360號，董事長為蔣玉蓮，總經理兼發言人為徐正哲。公司官網及股市資料顯示實收資本額為524,880,820元，已發行普通股52,488,082股。113年度年報揭露，主要關係企業包括100%持有之上鋌營造股份有限公司與Tri Ocean Textile (Thailand) Co., LTD；上鋌營造實收資本額1,500,000仟元，主要從事綜合營造業，是集團承攬政府工程標案的重要主體。主要股東方面，年報揭露114年3月30日前十大股東包括鴻鋌企業股份有限公司持股30.94%、順鎂興業股份有限公司持股21.58%、董事長蔣玉蓮本人持股3.81%且配偶及未成年子女另持股4.89%、洪鴻章持股4.89%、永駿投資股份有限公司持股2.09%、大員尚青股份有限公司持股2.04%、陳芳卉持股2.08%、黃俊銘持股1.80%、張凱菁持股1.77%、黃朝助持股1.60%。員工規模在可讀來源中未能可靠確認。

Business

公司目前為營運公司且屬普通股，主業已由紡織轉為營建工程。113年度年報顯示，營業收入淨額2,335,467仟元，產品項目為營建工程，營業比重100%，銷售地區為內銷100%。主要服務包括住宅工程、商辦大樓、公共工程、廠房及其他特殊工程；用途涵蓋政府國宅、宿舍、辦公大樓、醫院、學校、捷運工程、公路、土木橋樑、廠房工程等。商業模式以透過母公司與100%子公司上鋌營造之甲級營造廠資格，參與公部門公共工程投標、社會住宅統包工程、機場與港務工程、運動場館、污水與水利工程、太陽光電及基礎設施工程，依工程進度認列營收。年報列示仍有效或近期到期的重要契約客戶包括屏東縣政府、高雄市政府工務局新建工程處、高雄市政府水利局、台南市政府工務局、國家住宅及都市更新中心、交通部民用航空局與高雄國際航空站、臺灣港務股份有限公司高雄港務分公司與花蓮港務分公司、屏東縣海洋及漁業事務管理所、內政部國土管理署等。公司揭露主要承攬公共工程，業主多為政府機關，無銷貨集中風險；工程發包視工程性質委由適合之下包承攬商，進貨對象分散，無進貨集中風險。

Outlook 2025–2028

2025至2028年展望以公共工程、社會住宅、機場港務建設、產業園區與綠電相關工程為核心。公司113年報指出，114年度營業計畫將維持爭取高附加價值工程標案，主要營收動能鎖定公共工程營造與社會住宅案源；短期計畫重點為工程進度、品質驗收、成本管理、工安與內部流程改善，長期計畫為積極參與公共工程投標，並配合政府新能源政策投標太陽能、風能及其他綠電相關工程。產業面，公司年報引用之判斷為2025年公共建設預算提升、高科技業者建廠計畫持續推進，有利整體工程量能，但成長可能較2024年趨緩，且存在政策面與供給面執行不確定性。技術面，公司投入BIM、移動式CCTV、緊急廣播通報、人臉辨識、智慧工地管理、機械手臂噴漆與外牆打底粉刷，以及預鑄構件自動化澆築、振動成型、智慧養護等方向；112年與趙建銘建築師事務所成立營建自動化小組，並與逢甲建築學院ROSOCOOP實驗室合作。2026年2月公司公告與麗明營造共同取得高雄市白埔產業園區133億元開發標案，公司占比50%，開發時程預計2026至2030年，依進度認列營收，屬2026至2028年乃至2030年的重要成長來源；同一公司新聞稿並稱2025年全年合併營收36.43億元、創年度新高，並指出既有公共工程、太陽能工程、社會住宅、水利工程等業務延續。主要風險包括營造業缺工、人工與建材價格維持高檔、綠色工法增加成本、金融體系對營建業融資態度偏保守、國際大型營造業進入國內市場、公共工程執行進度與政策預算變動、工安與品質管理風險、資訊安全風險，以及長工期工程之成本估算與請款時程風險。

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.
