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.

80-100 You are here759+6% +3.7% 62.5% -14.1%

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 ≈ 48.04, at the 98.9th 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.

Business

長興為材料製造商,核心商業模式為研發、生產與銷售合成樹脂、特用材料與電子材料,並提供部分電子材料設備與精密塗佈相關解決方案。2024年三大事業部門營收占比依公司永續報告為合成樹脂47.71%、電子材料25.53%、特用材料26.31%。合成樹脂為公司歷史最久業務,產品包括塗料樹脂、聚酯多元醇、聚氨酯樹脂、醇酸樹脂、壓克力塗料樹脂、不飽和聚酯樹脂、乙烯基樹脂、阻燃樹脂、結構膠與配方環氧樹脂等,應用於建築塗料、木器塗料、罐裝塗料、汽車修補漆、膠帶、商標、膜材貼合、硬質發泡、鞋用膠、玻纖、風電機艙罩、交通載具、人造大理石與一般工業品。特用材料以光固化材料為主,包括丙烯酸單體、寡聚體、特殊塗料、有機矽材料、光學膠、3D UV材料、鋰離子電池材料、生質或環保型材料等;下游應用包含印刷油墨、膠黏劑、塗料、3C家電、新能源、電動車、3D列印、光學膜與功能性膜材。電子材料包括印刷電路板用負型水溶性乾膜光阻、乾膜防焊光阻、UV硬化文字油墨、薄膜感光型聚醯亞胺光阻材料、覆銅箔基板、平面顯示器與觸控面板材料、液態聚醯亞胺材料、真空壓膜機、精密塗佈代工、親水膜、晶圓級液態封裝材料等,應用於PCB、IC載板、FPC、顯示面板、觸控、半導體先進封裝與光學材料。公開資料稱長興為亞洲大型合成樹脂廠、全球主要乾膜光阻供應商、全球主要UV光固化樹脂供應商之一;2024年銷售地區營收比重約台灣10%、中國大陸58%、其他地區32%。

Outlook 2025–2028

2025至2028年展望以產品組合高值化、海外產能布局、PCB與半導體材料需求、環保低VOC與UV光固化趨勢為主軸。2025年公開法說摘要曾提及公司原先預期營收可成長5%至6%,電子材料因PCB景氣復甦與精密設備回溫而成長率較高,特用材料受路竹與蘇州新增產能開出帶動,合成樹脂則因2024下半年基期較高與中國市場競爭激烈而較保守;但後續2025年前三季摘要顯示合併營收約305億元、毛利率維持約20%,公司估2025全年營收約400至410億元,低於2024年441.91億元,反映中國大陸景氣與競爭壓力。2026年起,公司展望偏正向,主要來自東南亞市場擴張、馬來西亞廠稼動與電子材料塗布線、半導體新材料貢獻、子公司長廣精機精密機械設備成長,以及高毛利產品比重提升。產能方面,公開法說摘要提到特用材料蘇州廠2025年新增約1萬噸產能,路竹廠更新老舊廠區、目標產能由約1.2萬噸提升至2.8萬噸,安徽合成樹脂新廠投資約新台幣30億元並規劃2025年稼動,馬來西亞廠為東南亞成長重點且電子材料塗布線最快2026年下半年投產。中長期至2028年,公司研發方向聚焦生醫材料、先進構裝材料、高頻高速電子材料、綠能儲能材料、風電與鋰電池材料、水性UV、生質材料、晶圓級液態封裝材料等。產業趨勢上,全球減碳、低VOC、節能製程、智慧製造、PCB高階化、AI伺服器與先進封裝均有助特用材料與電子材料需求;風險包括中國市場價格競爭、石化原料價格波動、匯率與關稅、地緣政治造成供應鏈調整、電子業客戶認證週期長、半導體材料開發失敗或量產時程延後、環保法規與安全合規成本上升。2027至2028年具體量化財測未見公司正式公開揭露,本段屬基於公司公開投資方向與產業趨勢的研究推估。

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.
