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)
0-20 854+19.2% +4.1% 63.9% +2.7%

80-100 You are here1083+6.3% -1.2% 47.2% -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 ≈ 33.56, at the 93.0th 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.

Business

南帝主要從事合成橡膠乳液、丁腈橡膠、精煉膠與熱可塑性橡膠之製造與銷售。官方主要營業概況列示產能與用途:NBR/SBR合成橡膠乳液產能林園253,000噸/年、鎮江15,000噸/年,應用於檢驗手套、醫療手套、銅版紙與白紙板塗布、地毯背膠、鞋中底、不織布含浸、接著劑、塑膠改質、建材與人工皮革底材;丁腈橡膠NBR產能林園15,000噸/年、鎮江52,000噸/年,應用於油封、墊圈、耐油膠管、鞋底、汽車零件、保溫器材、運動器材、滾輪與電子零件;TPE產能7,000噸/年,應用於汽機車部品、建築工程、食品工業、運動器材、生活用品、工業製品、3C與醫療器材;精煉膠產能2,000噸/年,應用於油封、墊圈、膠管、鞋底與汽車零件。2026年第一季合併收入細分為乳膠類約6.781億元、橡膠類約11.921億元、有機無機材料約7.241億元、其他業務約0.014億元,合計25.957億元;部門外部收入為南帝本體8.732億元、英泰美及鎮江體系9.976億元、南美特7.249億元。2025年法說與市場摘要指出產品比重約為乳膠25.7%至28.1%、橡膠44.2%至46.05%、其他約27.7%至28.28%,乳膠以手套用NBR Latex、紙張塗布、地毯背膠等為主,橡膠以汽車部品、耐油橡膠製品、運動鞋底等為主;南美特則提供CVD/ALD電子化學材料、奈米陶瓷金屬塗料、防鏽扣件封口劑及電鍍、封口加工服務。商業模式屬石化衍生單體採購後聚合、配方研發、量產銷售與技術服務,收入受丁二烯、丙烯腈、苯乙烯等原料價格、手套與工業橡膠需求、稼動率及產品利差影響。

Outlook 2025–2028

2025年為景氣修正年:公司公告2025年度合併營收95.464億元、營業毛利21.325億元、營業利益7.041億元、稅前淨利10.003億元、歸屬母公司淨利4.105億元、EPS約0.83元;較2024年營收約113.64億元反彈後再度下滑,主因可歸納為手套用乳膠需求與售價疲弱、同業競爭激烈、原料成本轉嫁不易。2026年初資料顯示短期營運已有回溫跡象:2026年第一季合併營收25.957億元,年增約14.3%,稅前淨利4.002億元;2026年4月合併營收13.10億元、年增47.3%,前4月累計約39.06億元、年增23.57%;2026年5月合併營收10.85億元、年增15.92%。2025至2028年主要成長動能包括:醫療與檢驗手套庫存去化後需求正常化,馬來西亞、泰國等東南亞手套產能利用率回升;美國對中國醫療手套或相關產品關稅與供應鏈重組,可能提升非中國手套供應鏈與上游NBR乳膠需求;南帝持續發展高值化合成橡膠、醫材、車用、科技應用材料,並借重南美特在半導體電子化學材料與表面處理材料之成長;鎮江南帝可服務中國內需NBR市場,林園廠則支援外銷與高階產品。2025至2028年主要風險包括:中國及全球NBR乳膠過剩產能壓力、醫療手套價格紅海、丁二烯與丙烯腈價格波動、客戶成本轉嫁能力不足、匯率波動、環保與工安成本、地緣政治及中國市場需求不確定性。2027至2028之具體量化展望未見公司公開財測,故此期間僅能以產業趨勢與已揭露策略推估,信心低於已公告財務數字。

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.
