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)
0-20 343+19.3% +6% 68.8% -12.5%
20-40 322+19.1% +6.2% 63.7% -12.6%

60-80 You are here390+8% -1% 48.7% -3.9%
80-100 172+14.4% +9.9% 100% -9.7%

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 ≈ 13.93, at the 79.6th 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

公司為甲級機電工程執照承商,主要業務分為機電系統整合工程與運動場館營運管理。機電工程涵蓋電氣、自來水、消防、監控、空調、無塵室等系統整合,服務範圍包括賣場、量販店、百貨公司、觀光飯店、醫院診所、辦公大樓、集合住宅、高科技廠房、電子業無塵室、公共工程及特殊機電,提供設計規劃、施工管理、測試驗收、教育訓練、保養維護等服務。工程商業模式以公開招標、指定邀標或議價取得專案,經投標前業主信用評估、圖面數量清算、工程成本評估、簽約後採購發包、工程施工、設備驗證測試、完工驗收及保固認列收入;收入會隨大型工程進度集中認列。運動場館營運自2013年投入,透過委外經營管理模式經營國民運動中心、籃球館等場域,收入來源包含政府委辦營運、場館使用、課程、活動與相關服務。2025年前三季依第三方整理,委辦營運收入占比約44.47%,商辦大樓約24.70%,廠房及其他約30.83%;此占比受工程缺工遞延影響,未必代表長期結構。公司2024年年報揭露近兩年無單一供應商進貨占比超過10%,進貨對象分散;2024年銷貨客戶以代號揭露,UL占24.26%、FE占10.12%、TK占10.02%,因契約約定未揭露完整客戶名稱。主要終端應用為商辦、廠辦、物流中心、高科技廠房、百貨商場、運動休閒場館與公共設施。

Outlook 2025–2028

2025年至2028年展望以工程進度恢復、商辦與廠辦需求、物流中心投資、半導體及高科技廠務機會、運動場館智慧化為核心。公司113年年報指出,台商回流、觀光與航空復甦、商辦與廠辦需求增長有助國內機電工程市場,但需留意外部政經與供應鏈成本變動。公司短期策略為爭取廠辦及商辦短期建案、選擇信譽良好的長期合作客戶與優質業主;長期策略為強化系統整合、研發新工法、導入BIM建築資訊模型、培養機電工程人才。運動場館方面,公司短期將參與各縣市國民運動中心及大型複合式體育館OT投標,長期推行大數據、AI、智慧設備、智慧客服、泳池防溺、空氣品質偵測等智慧場館方案,並規劃新型態運動場館。2025年營收下滑主因包括新承攬工程可認列收入較少、營建缺工造成工程進度遞延、板橋運動中心ROT整修影響部分營運;2026年起若聯華食品富岡物流中心、酷澎彰化物流中心、遠東SOGO大巨蛋裝修、遠東國際會議中心等短工期案按期完工,營收認列可望改善;台肥南港C4商辦大樓預計2028年第一季完工,屬較長期工程動能。公司2025年12月通過台積電新建工程合格廠商評鑑並開始參與相關投標,若能取得高科技廠房案,將提高成長彈性,但目前尚不能視為已確定訂單。主要風險包括工程缺工、原物料及設備價格波動、工程低價競爭、專案認列集中導致營收波動、業主信用與驗收時程、公共場館委外標案續約與投標風險、智慧場館投資效益不確定、供應鏈成本受匯率與國際政經影響。

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.
