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 here320+32.3% +27.5% 86.6% +16.1%

80-100 425+14.4% +12.3% 87.3% -1.5%

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 ≈ 9.47, at the 19.6th 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

大山為台灣中部地區大型電線電纜製造商,主要生產電力電纜、通訊電纜、電子線、裸銅線、銅板及其他電線電纜相關產品。TWSE 個股資料列主要經營業務為各項電線電纜配件、絕緣材料、銅線之製造、加工及銷售,相關機械及配件製造加工銷售,以及 E601011 電器承裝業。114年度產品營收分布為:電力電纜4,863,946.99千元、85.05%;通訊電纜212,790.59千元、3.72%;電子線29,167.15千元、0.51%;裸銅線116,006.70千元、2.03%;銅板及其他496,931.25千元、8.69%。商業模式以採購銅材、基本金屬與塑膠/橡膠絕緣材料,透過斗六總公司與虎溪廠等產能製造中低壓與中高壓電力電纜、通訊與電子線材,再銷售給國營機關、公共工程、台電電網工程、水電工程商、建築與都更/危老重建市場、產業園區與一般通路。終端應用包括輸配電、變電與電網工程、建築配線、工廠與產業用電、通訊網路、資訊/家電/機械設備內部配線。公司官網列有總公司、虎溪廠、高雄營業所、桃園營業處;114年股東報告並提及桃園營業處績效逐漸顯現,計畫設立台中營運據點以擴大中部市場。

Outlook 2025–2028

2025年:114年度合併營收淨額5,719,049千元,較113年度衰退3%,稅前淨利1,163,540千元,稅後淨利945,324千元,每股稅後純益4.81元;產品結構仍高度集中於電力電纜。2026年:公司115年度營業計畫主軸為掌握國際原油、基本金屬與匯率波動,穩定原料貨源與存貨週轉,積極爭取台電電網強韌計畫、都更、危老重建、台商回台與公共建設相關電線電纜商機;預估各式電線電纜銷售總量18,000公噸,並推動耐火耐熱電線電纜、網路電纜新技術、遮蔽電纜市場、設備更新與作業無人化。2027至2028年:可確認的長線需求來自台電2022至2032年強化電網韌性建設計畫,總投資規模5,645億元,搭配再生能源併網、AI與高科技產業用電增加、產業園區與公共工程,將持續支撐中高壓與輸變電電纜需求;大山的中高壓電力電纜、69至161kV建設/量產經驗、區域通路擴張與智能化生產,為主要成長動能。2025年媒體與產業資料指出台電釋出逾190億元161kV交連PE電纜及附屬器材標案,大山為主要得標線纜廠之一,此類標案有助未來數年接單能見度,但個別公司可認列金額與時程仍需以公司公告與財報為準。主要風險包括銅價、油價、塑膠與基本金屬價格劇烈波動,匯率波動,原料供應不確定,公共工程標案競爭與毛利壓力,勞動人力短缺,保護主義與地緣政治造成供應鏈波動,以及營收高度依賴電力電纜與國內公共建設需求。

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.
