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)
0-20 931+36.3% +34.9% 81.8% +17.4%
20-40 You are here430+31.2% +34% 78.8% +2.9%

80-100 453-10.5% -18.5% 21.2% -29%

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 ≈ 13.7, at the 36.5th percentile of its own history (20-40 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.

What does 金益鼎 do? Company profile

綠能環保、電子廢棄物處理、貴金屬與銅資源回收 上櫃

Overview

金益鼎企業股份有限公司,股票代號8390,為櫃買中心上櫃普通股。公司成立於1997年4月10日,總部位於新竹市香山區西濱路六段599號,另有高雄分公司。2008年5月21日於證券櫃檯買賣中心掛牌上櫃。董事長為莊清旗,總經理為莊瑞元,發言人為莊瑞瑾。實收資本額為新台幣961,161,280元,已發行普通股96,116,128股。104人力銀行公司頁揭露員工數約160人。主要股東截至2025年4月20日包括:鎰鼎股份有限公司持股12.20%、莊瑞元5.54%、莊瑞瑾4.19%、元龍投資有限公司3.83%、合瑞投資股份有限公司3.50%、莊清旗1.93%、黃日東1.46%、東皇投資股份有限公司1.46%、彭慧琪0.98%、李依錦0.93%。2025年度合併營收新台幣46.35億元,EPS 6.60元,2025年度現金股利每股3.8元。公司取得甲級廢棄物清除及處理許可,定位為電子廢棄物專業回收處理與城市採礦業者。

Business

金益鼎主要處理半導體、PCB、電腦零組件、光電、被動元件、通訊與其他含有價金屬之事業廢棄物,透過分類拆解、粉碎分選、電析、貴金屬精鍊、半導體元件洗淨等流程,從廢電子零件、廢積體電路、廢印刷電路板、貴金屬廢液、鍍鍋與蒸鍍機耗材、廢電鍍液等料源中回收金、銀、鈀、鉑、銅、錫、鎳、鋁等金屬,並銷售4N金、4N銀、4N鈀、4N鉑、電解銅、光亮銅、銅米、銅粉及含貴金屬資源物。公司亦提供貴金屬廢液現場回收、代工精鍊、半導體檔板元件洗淨、廢棄物清除處理與一般性資源回收服務。2025年度產品組合為銅約44.7%、金及含金混合貴金屬約39.4%、其他約15.9%;公司年報文字亦揭露金及含金混合貴金屬約39%、銅約45%、其他約16%。商業模式兼具處理服務收入、回收金屬銷售與代工精鍊,獲利受回收量、處理效率、金銅等金屬價格、料源穩定度及環保法規影響。公司網站稱已獲國際電子大廠認可,並在美國、日本、比利時及香港有長期合作夥伴,可銷售所產製之貴金屬;具名客戶多未公開,財訊快報2020年報導曾指其服務客戶超過260家、逾80%為上市櫃公司,並提及台積電與NVIDIA相關業務,但該資訊年代較久,需以後續公司公告驗證。

Outlook 2025–2028

2025至2028年展望重點包括:(1) AI、資料中心、高階電子與半導體產業擴張帶動電子廢棄物、含金固料、PCB與製程廢液處理需求,金、銅等回收金屬價格若維持高檔,將有利回收品銷售價值與毛利,但也提高存貨與價格波動風險。(2) 太陽能板退役潮為新成長動能,公司已取得新竹西濱新廠廢太陽能板完全處理製程許可,並稱取得台灣、日本、美國、澳洲等多國專利;西濱新廠2026年1月全面商轉,預期2026下半年起承接退役太陽能板處理商機,2027至2030年前後可能受惠第二波電子金屬與太陽能板退役需求。(3) 海外布局方面,泰國廠位於北柳府Gateway City工業區,2025年11月動土並取得泰國BOI重大投資優惠,目標服務東南亞台商電子製造業與PCB供應鏈;美國廠針對美國清潔競爭法案與在地化供應鏈需求建置回收處理基地,MoneyDJ 2026年6月報導稱美國廠已在營運中;香港廠2025年營收約占整體18%、獲利約占13%,為全球品牌客戶提供廢棄物處理服務。(4) 技術面,公司近年研發方向包括提高金屬回收率、減少化學藥劑使用、廢電池有價金屬鈷回收、含銠廢液回收、磁性物料稀土釹與鐠回收、永磁材料回收、太陽能板專利破碎與物理分選技術及技術授權。(5) 主要風險為國際金、銅、鈀、鉑價格大幅波動,料源競爭,環保許可與跨國法規合規成本,泰國與美國新廠建置進度、良率與產能利用率不如預期,匯率變動,客戶集中或大型電子客戶稽核要求,及同業擴產導致處理價格競爭。

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.
