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)
0-20 212+0.3% -7.5% 21.7% -16%

80-100 You are here358-10.7% -19.7% 19.3% -23.8%

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 ≈ 100.71, at the 88.0th percentile of its own history (80-100 band).

Valuation × momentum historical grid

What does 海光 do? Company profile

鋼鐵工業 台灣證券交易所上市

Overview

海光企業股份有限公司為台灣上市普通股,股票代號2038,產業別為鋼鐵工業。公司成立於1969年3月21日,總部與主要地址為高雄市小港區沿海二路12號,2008年12月30日於台灣證券交易所掛牌上市。董事長為黃韋翰,總經理/執行長為黃燦明,發言人為楊建璋。實收資本額為新台幣1,941,343,030元,已發行普通股194,134,303股。公開徵才資料顯示員工約500人;Goodinfo揭露2025年全體員工平均薪資為71.5萬元/人。公司官網自述願景為區域性專業建築鋼料領導品牌。主要股東與董監持股方面,公開資訊可見海明投資、佑明投資、玉展投資及董事長黃韋翰等關係人/法人持股;鉅亨網資料顯示全體董事、監察人、經理人及持股10%以上股東合計持股約32.62%,但截至本研究未取得完整最新前十大股東名冊。公司歷史沿革包括1970年代建立電弧爐煉鋼與連鑄設備、1993年嘉興廠量產、2007年登錄興櫃、2008年上市、2015年嘉興廠成立鋼筋加工成型部門、2016年設立証統環保科技子公司。

Business

海光為南部專業電爐煉鋼與軋鋼廠,主要從事鋼胚、鋼筋之製造、加工、銷售與買賣,主要產品包括竹節鋼筋、小鋼胚,並延伸至鋼筋裁剪加工、黑鐵絲/炖線等相關產品。鋼胚為軋製鋼筋及線材的半成品,鋼筋主要用於土木建築、公共工程、住宅與廠房建設。MoneyDJ資料指出2024年產品結構中鋼胚與鋼筋製造買賣占約97%。公司生產據點位於高雄,包含小港廠與嘉興廠;小港廠有煉鋼與軋鋼設備,嘉興廠為軋鋼及加工相關據點。商業模式以採購廢鋼等原料,透過電爐煉鋼、連鑄、軋延與加工,銷售鋼筋/鋼胚給國內盤商、營造商、建設公司及公共工程相關需求端。MoneyDJ資料指出鋼筋銷售以台灣市場為主,客戶約8至9成為盤商,1至2成為直接客戶如營造商等;2024年鋼筋銷售及裁剪加工服務100%為國內市場,台灣鋼筋產銷市占率約8%至9%。2025年公司營業收入約89.23億元,較2024年減少;官網財務資料列示114年度營業收入8,923,105千元、營業毛利117,580千元、營業淨利為負77,677千元、稅前淨利為負126,861千元。

Outlook 2025–2028

2025年實際營運受國際鋼價震盪走跌與國內鋼筋需求轉弱影響,鋼筋銷售量約48.56萬噸、年減0.79%,營業收入淨額約87.63億元、年減8.37%,營業淨利0.48億元、年減67.78%,稅前轉為虧損。主要壓力來自中國房地產低迷與鋼材出口維持高檔、東南亞需求疲弱、國內央行信用管制與打炒房政策使建商推案及新屋開工趨緩,以及電價、天然氣、碳費等成本負擔。2026至2028年未查得公司發布明確量化財測或產能目標,因此僅能以產業與公司公開營運方針推估:成長動能包括社會住宅、公共工程、工業與科技廠房建設需求、公司與直接客戶合作參與公共工程、鋼筋加工成型服務提升附加價值、更新供氧/集塵/連鑄/入料/軋機/冷卻床等設備以提升效率並降低能源與物料耗用,以及ERP、AI、IoT、雲端技術導入以推動自動化與數位化。子公司或關係業務方面,公司年報文字提到擴大表面處理客群、提高特殊螺絲業務比重、推動廢水處理業務,可能成為非鋼筋主業的補充成長來源。主要風險包括亞洲鋼品供過於求、鋼筋售價跌幅大於廢鋼成本降幅造成毛利壓縮、房市管制延續導致民間建案需求不振、公共工程施工進度延宕、存貨跌價損失、能源價格與碳費增加、電爐設備折舊與維修成本、同業競價、進口鋼材價格壓力及景氣循環波動。

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.
