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)
0-20 385-10.9% -22.1% 20% -13%

80-100 You are here217+70.5% +55.6% 93.5% +47.3%

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 ≈ 97.5, at the 96.3th 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

台達化為苯乙烯系塑膠與玻璃棉材料製造商,主要產品包括 EPS 發泡級聚苯乙烯、ABS 樹脂、GPS 通用級聚苯乙烯、SAN/AS 樹脂、HIPS 耐衝擊聚苯乙烯與玻璃棉。2025 年產品別收入依公司 2026 年法說會:EPS 中山約新台幣 43.35 億元、占 30%;ABS 約 40.85 億元、占 28%;GPS 約 33.29 億元、占 23%;EPS 台灣約 21.79 億元、占 15%;玻璃棉約 5.58 億元、占 4%。114 年年報所列營業比重為 EPS 44.97%、ABS 28.20%、GPS 22.94%、玻璃棉 3.85%、IPS 0.04%。營運據點與產能:林園廠 ABS/SAN 年產能 12 萬噸;前鎮廠 GPS/IPS 年產能 10 萬噸、EPS 年產能 6 萬噸;中國中山廠 EPS 年產能 18 萬噸;頭份玻璃棉年產能約 1 萬噸。商業模式為採購 SM、AN、BD、石油醚、矽砂等原料,透過聚合、混煉造粒、發泡聚合與玻璃棉熔融成型製程生產材料,銷售予塑膠加工、包裝、家電、3C、建材、冷鏈、漁箱、食品容器、隔熱隔音與工業保溫保冷等客戶。公司揭露下游客戶以中小型加工企業為主,2025 年合併公司無銷售額占整體銷售額 10% 以上之單一客戶,因此客戶集中度不高。終端應用包括家電外殼與包裝、3C 配件、導光板、食品容器與包裝盒、建築保溫外牆、安全帽緩衝、空調風管、金屬屋頂與牆壁斷熱、地板隔音、乾式隔間填充、石化與機械設備保溫保冷等。

Outlook 2025–2028

2025 年公司面臨全球需求低迷、美國關稅政策不確定、地緣政治與中國大陸 ABS/PS/EPS 產能外溢競爭;年報指出 ABS 受印度 BIS 撤銷衝擊,2025 年銷售量較 2024 年減少約 5%,GPS 銷售量小幅衰退約 2%,EPS 受中國出口量增加與低價搶單影響,台灣前鎮與中山 EPS 毛利壓力較大。2026 年法說會表示 Q1 受中東地緣衝突帶動原油、苯乙烯等原料價格上漲,ABS/GPS/EPS 價格反彈,但趨勢仍高度跟隨原料波動;2026 年中國預估新增產能仍包括 ABS 約 197 萬噸、EPS 約 120 萬噸,供需失衡與價格競爭仍是核心壓力。成長動能方面,公司策略為維持產銷極大化、降低單一海外市場依賴、開發大陸及香港以外市場,ABS 主要開發印度、東南亞、巴基斯坦等,GPS 主要開發非洲、東南亞、中南美等;2025 年非大陸/香港市場占比已揭露 ABS 約 88%、GPS 約 95%。產品與技術方面,公司計畫推動 TAIECOR PIR ABS ESG 環保材料、高值化 SAN 水材應用、ABS 光澤度改善、PS 飲用水材產品應用、快速成型 EPS、包覆式玻璃棉、AI 製程/研發/工安環保解決方案、低碳與高值化產品。2027-2028 年展望屬推估:若中國新增產能放緩、老舊產能淘汰、東南亞/印度/中東/非洲/中南美需求承接出口,台達化可望以新市場、客製化產品、NOVA 製程 GPS 低殘留單體優勢、EPS 防火級/抗靜電級與玻璃棉隔熱隔音應用支撐稼動率;但若中國 ABS/PS/EPS 供給過剩延續、原油與 SM/AN/BD 價格劇烈波動、海運費與匯率不利、禁塑政策擴大、印度/各國認證或關稅壁壘加嚴、台灣電價與天然氣成本上升,則毛利率與銷量仍可能承壓。

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.
