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)
0-20 257+8.8% +6.3% 79% -19%
20-40 162+20.5% +16.9% 100% -21.2%

80-100 96+11% +7.3% 90.6% +6.9%

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 ≈ 17.74, at the 71.7th 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.

What does 鋼聯 do? Company profile

綠能環保;資源再生;有害事業廢棄物清除、處理與再利用;粗氧化鋅製造銷售 上市

Overview

6581 對應台灣鋼聯股份有限公司,為台灣證券交易所上市普通股,股票簡稱鋼聯。公司成立於1995年5月24日,總部與工廠位於彰化縣伸港鄉彰濱工業區線工北一路36號,2018年1月30日上市,統一編號89528054。主要經營廢棄物清除、處理、資源回收再利用、其他非鐵金屬基本工業、水泥與混凝土製品等業務。董事長為林才翔,總經理為謝宗霖。實收資本額為新台幣1,112,708,870元,已發行普通股111,270,887股。公司2024年永續報告書揭露台灣鋼聯員工總人數109人;求職平台資料另列員工約93人,口徑不同。前十大股東依公司股務資訊資料日2026年3月31日:豐興鋼鐵24.05%、東和鋼鐵22.31%、海光企業8.71%、協勝發鋼鐵廠8.70%、建順煉鋼5.50%、誠創投資3.74%、龍慶鋼鐵3.63%、李衍慶3.55%、聯成鋼鐵3.39%、威致鋼鐵3.01%。公司另100%持有台鋼資源股份有限公司,處理旋轉窯爐碴安定化與再利用。

Business

台灣鋼聯的核心商業模式是收受國內電弧爐煉鋼業產生的有害事業廢棄物集塵灰,以及其他含鋅廢棄物、焚化飛灰、污染土壤等資源物,透過自德國引進的Waelz Kiln旋轉窯高溫冶煉製程,在約1300°C、5至6小時反應下回收鋅、鉛等有價金屬,產出粗氧化鋅與可再利用旋轉窯爐碴。兩座旋轉窯設計年處理量約198,900公噸;粗氧化鋅年產量約5萬至6萬公噸,品質區間公司揭露為Zn約45%至60%,主要作為國外冶煉廠或化工廠原料,經精煉後可製成99.995%鋅錠或高純度氧化鋅,再應用於鍍鋅建材、輪胎、橡膠、陶瓷、化學品、農業、工業製品等。2024年營收結構:氧化鋅銷售新台幣16.19億元、占68%;清除再利用7.13億元、占30%;混凝土銷售0.39億元、占2%;其他約0.08億元。依2024年年報,主要銷售地區含日本37.12%、歐洲11.81%、泰國11.70%、韓國2.90%、氧化鋅內銷4.55%、清除再利用29.96%、其他1.96%。公司指出粗氧化鋅約90%外銷、10%內銷;主要客戶為日本、泰國、比利時及波蘭大型冶煉廠,合計約占粗氧化鋅銷售金額93%,化工廠客戶約占7%,但未公開具名客戶。國內電弧爐集塵灰清運再利用市場,2024年公司處理116,900噸、市占率約92.12%,公司稱其國內集塵灰再利用市場居領導地位。

Outlook 2025–2028

2025年:公司2025年營收為22.11億元,稅後純益6.87億元,EPS 6.17元,年減約17%;主因國內鋼鐵產量下滑,影響集塵灰交量與可銷售氧化鋅數量。支撐因素為國際鋅價上漲、鋅礦供應緊張,以及2025年長約加工費由每噸165美元降至80美元,推升氧化鋅產品價值。公司法說會並指出2025年氧化鋅已完售、供不應求,且持續推動AI資訊系統精準投料、節能減碳、拓展再利用項目、多元化經營。2026年:成長動能主要來自環評變更通過與龍井新廠興建。環差變更重點為擴大含鋅資源物來源與收受量,以及增加國內焚化廠焚化飛灰收受量;公司也取得UL 2809再生材料含量認證,標示產品鋅100%來自廢棄物,有利綠色循環產品銷售。國際鋅價若維持高檔、加工費維持低位,對營收與毛利有正向影響;但國內鋼鐵產量、廢鋼與鋼價、公共工程與營建需求仍會影響集塵灰原料量。2027年:龍井新廠目標2027年底前完工並正式營運,重點為水洗氧化鋅產品,提高產品價值、開拓客源並降低雜質帶來的折價,若準時投產,可能成為2028年前後營收與客戶結構升級的核心。2028年:推估成長將取決於龍井新廠產能爬坡、環評新增收受項目實際放量、焚化飛灰與含鋅污泥等新料源穩定性、國際鋅價與加工費週期、以及國內外對再生鋅與低碳材料的需求。主要風險包括鋼鐵景氣低迷導致集塵灰交量不足、LME鋅價下跌、加工費反彈、環保許可與地方溝通延宕、新廠資本支出與試車風險、匯率波動、主要外銷客戶集中、以及含鋅廢棄物與焚化飛灰成分不穩造成處理成本上升。
