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)
0-20 242+27.5% +41.7% 68.6% +17.9%
20-40 85-23.2% -22.7% 0% -19.3%

80-100 115+12.5% +11.8% 71.3% -35.5%

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 ≈ 45.76, at the 58.1th percentile of its own history (40-60 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 三晃 do? Company profile

化學工業 台灣證券交易所上市

Overview

三晃股份有限公司為台灣上市普通股,股票代號1721,產業別為化學工業。公司前身為三晃油墨股份有限公司,成立於1974/12/31,1995年更名為三晃股份有限公司,1996/05/16於台灣證券交易所掛牌上市。總公司位於台中市西區中興街229號5樓,並有大里、平鎮、大甲、全興、南崗及竹南園區分公司等據點。依2026年4月法人說明會,公司主要產品為植物保護用藥、特用化學品、高分子塑膠粒、合成樹脂;員工人數425人,資本額新台幣18.49億元,2025年合併營收新台幣17.75億元。Goodinfo資料顯示董事長為黃亭棣、總經理為張俊彬,發行股數約184,884,092股。主要股東方面,公司2023年年報揭露截至2024/04/14前十大中持股較高者包括美璽投資16,838,191股、凱棣股份有限公司10,801,010股、翹麗投資6,503,902股、黃沂榮5,988,685股、林玉萍3,146,718股、莊宏德1,928,809股;此主要股東資料為較舊官方年報資料,未找到2026年6月同口徑完整更新資料。

Business

三晃以化學品製造與銷售為核心,早期從油墨、油漆、人造皮革原料起家,事業版圖擴及高分子彈性體、特用化學品、環境與植物保護用藥、化妝品原料、原料藥與專業代工製造。產品包含TPU、TPV、PU樹脂、植物保護用藥、電子化學品、抗氧化劑、成核劑、交聯劑、阻燃劑等。依2026年4月法說會,2025年度銷售組合為:植物保護用藥4.739億元、27%;交聯劑3.759億元、21%;抗氧化劑2.671億元、15%;高分子2.286億元、13%;電子化學品1.897億元、11%;阻燃劑1.412億元、8%;其他0.807億元、4%;成核劑0.177億元、1%。商業模式以自有製程與配方開發、量產供應、依客戶規格客製化材料、共同開發與代工為主;終端應用包括農業殺蟲劑原體、橡塑膠安定劑、聚烯烴與工程塑料添加劑、高爾夫球芯交聯助劑、PCB黑化製程還原劑、銅箔基板及電路板阻燃材料、鞋材、紡織、管材、汽車與建築密封材料、生醫與軟管部件、運動用品、防水材料、接著劑與合成皮革表面處理劑。2025年營收較2024年22.87億元下滑至17.75億元,主因為中國石化產能過剩與低價輸出,使抗氧化劑、阻燃劑、成核劑等塑料添加劑售價承壓,高分子產品亦受終端需求疲弱與中國TPU低價競爭影響。

Outlook 2025–2028

2025至2028年的核心觀察是傳統石化添加劑壓力與高值化電子材料轉型並存。短期至2026年,公司法說會明確指出塑料添加劑供過於求未改善、售價疲軟,且上游原油與石腦油運輸或價格波動可能推升基礎原料成本;2025年公司毛利率為-7.30%、EPS為-1.84元,顯示轉型尚未完全反映在獲利。成長動能方面,公司未來發展聚焦Triazine抗UV劑、電子業化學品、新型含磷阻燃劑、磷酸酯阻燃劑、DOPO衍生物、BMI、PPE、半導體化學品、高分子SCF-TPU鞋材、不黃變TPU、易染色TPV、微米級解碎、化學品共同開發與代工,以及低環境成本製程。2025年11月法說會提到AI伺服器與通訊需求推升PCB、CCL材料規格,BMI品質已驗證合格並預計2026年量產推廣;改質PPE處於原廠品質驗證中並預計2026年量產;新型含磷阻燃劑已取得10公斤級訂單供客戶試做新一代基板;Triazine系列抗UV劑送樣驗證中。2026至2028年若上述產品順利通過客戶認證並放量,產品組合有機會由低毛利泛用塑料添加劑轉向較高技術門檻的電子材料與專業代工;但目前多數新品仍處驗證、試做或初期量產推廣階段,營收與毛利貢獻仍需逐季驗證。主要風險包括中國同業削價與產能外溢、石化原料價格與匯率波動、產線稼動率下降造成單位成本上升、庫存跌價損失、新產品認證時程不確定、AI/PCB/CCL終端需求波動、美國關稅對高爾夫球相關交聯劑客戶採購決策的影響,以及環保、碳費與ESG要求提高營運成本。

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.
