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.

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 ≈ 35.12, at the 97.9th percentile of its own history (80-100 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.

Days = trading days in this bucket; returns use adjusted prices, ex-costs. 60-day momentum: direction of this stock's price over the past 60 trading days.

Does this signal hold up across the market

Over the past 242 months, on average ~404 stocks per month met “monthly revenue YoY ≥ 20%”; their adjusted-close return over the next 60 trading days averaged 6.94% (equal-weighted), beating the market by 2.37 points on average, and outperformed the TAIEX total-return index in 64.5% of months.

Each month, equal-weighted 60-day forward adjusted return of all signal-matching stocks, then averaged across months; excess vs the TAIEX total-return index.

What does 中碳 do? Company profile

化學工業/煤化學與碳材料 TWSE

Overview

1723 對應台灣證券交易所上市普通股「中碳」,公司全名為中鋼碳素化學股份有限公司,屬中鋼集團工業材料事業群子公司,為國內唯一煤化學工業公司,並已延伸至精碳材料、鋰電池負極材料與半導體用石墨材料。公司成立於1989年2月3日,1998年11月27日在台灣證券交易所掛牌上市;總部位於高雄市前鎮區成功二路88號25樓,煤化學生產工廠位於高雄小港臨海工業區,碳材料生產工廠位於屏東枋寮屏南工業區。官方與公開資訊顯示實收資本額為2,369,044,800元,普通股約236,904,480股;2025年年報刊印日前資料顯示中碳及子公司員工合計351人,母公司個體員工334人,ESG公司概況頁揭露員工333人,差異主要來自統計口徑與時間點。董事長為黃建智,官方年報內控聲明與Yahoo股市資料顯示總經理為方明達;部分第三方股市資料仍列曾文良,判斷可能為更新時間差。主要股東依2024年9月官方法說簡報截至2024年7月15日:中國鋼鐵29.04%、國際中橡投資控股4.96%、富邦人壽3.93%、景裕國際投資2.01%、志成德投資1.46%。

Business

中碳主要商業模式是向中鋼、中龍等一貫作業煉鋼廠取得煤焦油、粗輕油與細焦炭等煉焦副產品,經脫水、蒸餾、提純、加氫脫硫、篩選加工、碳化、石墨化與相關深加工後,銷售煤焦油系列、輕油系列、焦炭系列與精碳材料系列產品,並從事相關上下游產品貿易。2024年合併營收結構依官方年報:煤焦油及化學品系列53.20%、輕油及油品系列29.03%、焦炭系列6.62%、精碳材料系列9.72%、其他1.43%。主要產品包括軟瀝青、雜酚油、洗油、精萘、苯、甲苯、焦炭粉、介相碳微球、介相石墨碳微球、高比表面積先進碳材、精製瀝青、黏結碳粉、等方性石墨塊材與石墨電極代理銷售。用途方面,煤焦油系列用於鋁電解電極黏著劑、防蝕塗料填充料、染料中間體、防腐材料與碳黑原料;輕油系列用於苯乙烯、己內醯胺、酚、烷基苯與溶劑;焦炭系列用於石灰窯燃料或電爐煉鋼增碳劑;介相碳微球用於鋰離子電池負極材料與石墨塊材;高比表面積先進碳材用於超級電容器與鉛碳電池。2024年煤焦油與輕油產品銷售量分別約214,261噸與80,000噸,精碳產品約7,732噸。年報揭露2024年主要供應商為中鋼64%、中龍29%;主要銷貨客戶為KCMC 17%、林園先進13%、DALIAN 8%、其他62%。公司市場地位上,煤焦油蒸餾產品在國內具唯一供應商優勢,煤瀝青、雜酚油與精萘等國內替代性低;苯產品與石油苯互為替代,國內市占約4%。銷售地區涵蓋台灣、澳洲、中國大陸、日本、韓國、東南亞、南亞與比利時等,產品外銷比率約45%至50%。

Outlook 2025–2028

2025至2028年展望可分為傳統煤化學循環與新碳材料成長兩條主線。傳統煤化學方面,2025年受國際油價與苯價走弱、中國大陸石化與煤焦油深加工產能過剩、下游需求保守、外銷匯率波動影響,煤化學與輕油產品報價承壓;但中碳具中鋼與中龍穩定料源、國內唯一煤焦油蒸餾工廠、銷售通路穩定與連續製程經驗,若油價、苯價、鋼鐵煉焦量與碳黑需求回穩,煤焦油、雜酚油、苯與焦炭產品仍可提供現金流基礎。新材料方面,公司明確以「煤化學及碳材料雙主軸」轉型:鋰電池負極材料中,介相石墨碳微球已應用於24M半固態電池技術,官方法說資料稱為該技術唯一驗證合格負極材料,隨日本與另一主要客戶產線投產,2026年需求量有跳升可能;UF系列負極材料與多孔矽碳材料瞄準高階手機、儲能與車用電池。先進碳材料方面,AI伺服器電力備援系統BBU、超級電容、鋰離子電容器、先進鉛酸電池、智慧電網與UPS是不斷電及高功率放電應用的成長題材;公司2025年2月董事會通過500噸先進碳材料工廠擴建案,第一期預計2027年初完工,第二期預計2030年底完工,若客戶驗證與量產順利,2027至2028年可望逐步拉高精碳材料營收比重與毛利率。等方性石墨塊材方面,產品用於SiC長晶坩堝與工業熱場構件,國內自製供應有限,6吋坩堝已通過多次長晶驗證、8吋由多家廠商驗證中、12吋預計2026年完成開發;240噸等方性石墨塊材工廠預計2027年初完工,受惠中國高純石墨出口管制與非中供應鏈需求,2027至2028年有機會形成半導體材料新收入來源。主要風險包括:中國煤焦油深加工與負極材料產能過剩壓價、碳材料客戶驗證與量產時程遞延、擴廠投資回收不如預期、外銷船期與儲槽限制影響連續生產、台幣升值壓縮營收與毛利、油價與苯價波動、環保與碳排成本、半固態電池與SiC市場滲透速度不確定。2026至2028具體營收與獲利數字未見公司正式長期財測,以上為依公開法說、年報與產業趨勢所做的情境式推估。

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.
