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)
0-20 393-3.4% -10.2% 23.9% -13.8%
20-40 514+38% +3.5% 59.1% +15.9%

80-100 You are here577+2.5% +0.3% 50.6% -10%

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 ≈ 92.0, 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.

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.

What does 亞聚 do? Company profile

塑膠工業/聚乙烯樹脂(LDPE、EVA) 台灣證券交易所上市

Overview

1308 對應亞洲聚合股份有限公司,簡稱亞聚,英文名 Asia Polymer Corporation,為台灣證券交易所上市普通股,產業別為塑膠工業。公司成立於 1977-01-25,1986-06-20 於台灣證券交易所上市;總公司位於高雄市林園區工業一路 3 號,台北營運總部位於台北市內湖區基湖路 37 號 12 樓,林園廠負責研發、製造與出貨,台北總部負責銷售業務。董事長為吳亦圭,總經理為吳培基。2024 年永續報告書揭露資本額新台幣 59.37 億元、員工 234 人、2024 年營收 60.31 億元、總產量 131,105 公噸、年產能約 14.5 萬公噸。主要股東包含聯聚國際投資股份有限公司 214,245,822 股、持股 36.08%,臺聯國際投資股份有限公司 14,311,014 股、持股 2.41%,全球人壽保險 13,552,000 股、持股 2.28%,中華郵政 7,934,820 股、持股 1.34% 等;聯聚國際投資為台聚 1304 之 100% 持股子公司,故亞聚屬台聚集團關係企業。公司沿革包括 1984 年第三條生產線興建與投產、2011 年第四條 EVA 生產線完工商轉、2017 年福建古雷投資案動工、2023 年古雷煉化一體化項目全部建成投產、2024 年高雄港區洲際二期乙烯地下管線工程完工並通過 ISO 14021 驗證。

Business

亞聚主要業務為低密度聚乙烯樹脂(LDPE)與乙烯醋酸乙烯酯共聚合樹脂(EVA)的開發、製造與銷售,採高壓製程於林園廠生產塑膠粒,依市場價格、利差與需求在 LDPE/EVA 之間調整產品組合。LDPE 產品分薄膜級、射出級、淋膜級與特用級,應用於包裝膜、軟管、家庭塑膠用品、發泡水果網袋、超細纖維、食品/飲料包裝材與離型紙等;2024 年 LDPE 產量 43,479 公噸、銷售量 45,248 公噸。EVA 產品分發泡級、光伏級、淋膜級與熱熔膠級,應用於中底鞋材、運動器材、電線電纜、太陽能電池模組封裝膜、BOPP/PET 預塗膜與護卡膜、熱熔膠等;2024 年 EVA 產量 87,626 公噸、銷售量 87,656 公噸。2025 年法說資料顯示,2025 年前三季 LDPE 銷量約 36,179 公噸、EVA 銷量約 64,973 公噸;EVA 應用占比約為 Lami-EVA 44%、發泡低 VA 20%、發泡高 VA 21%、PV 光伏膜 15%,而 2024 年前三季占比為 Lami-EVA 41%、發泡低 VA 23%、發泡高 VA 27%、PV 9%。商業模式為採購乙烯與醋酸乙烯酯等石化原料,經高壓聚合製成 LDPE/EVA 樹脂粒,銷售給塑膠加工、鞋材、包裝膜、印刷包材、光伏封裝膜、電線電纜與熱熔膠等下游加工廠;公司具客製化、產品切換與台聚集團原料/銷售協同優勢。具名主要客戶未在公開資料中明確揭露,僅能確認下游以加工廠與終端應用產業為主。

Outlook 2025–2028

2025 至 2028 年展望以產品組合調整、差異化與供需循環為核心。成長動能方面,亞聚持續拓展 Lami-EVA、塗覆級 LDPE、液包塗覆、超纖、高端發泡、熱熔膠、電線電纜、再生塑料與低碳材料 APGREN 等利基產品,並降低對光伏級 EVA 的依賴;2024 年已開發 9 支再生塑料產品並取得 ISO 14021 Pre-Consumer Recycled 材質認證,2025 年起購買綠電轉供,並規劃自發自用太陽能案場,對 ESG 材料與客戶減碳要求有正面助益。產業趨勢方面,EVA 仍受太陽能封裝膜、鞋材發泡、塗覆與熱熔膠需求影響,但中國大陸及韓國 EVA 新產能持續開出,2025 年法說指出韓國 30 萬噸 EVA 新線試車、2025 年底中國大陸仍有 54 萬噸 EVA 新產能,2026 年新聞報導亦指出中國大陸 EVA 新增產能約 140 至 155 萬噸、光伏新增裝機成長放緩,EVA 供過於求壓力可能較 2025 年更重。公司因應策略為持續拓展 Lami-EVA 市場、差異化產品與中國大陸以外市場(東南亞、南亞/印度等),並將部分產能轉向供應相對較少、競爭較緩和的 LDPE 塗覆與特用市場。中長期機會來自古雷煉化一體化項目與高雄港洲際二期乙烯儲運/地下管線工程,可改善原料調度、運輸成本與垂直整合能力。主要風險包括乙烯與 VAM 原料價格波動、油價與匯率波動、EVA 新產能造成報價承壓、太陽能需求放緩、鞋材與包材景氣循環、中國大陸低價競爭、碳費與環保法規成本、客戶去庫存,以及高壓製程石化廠的工安與停工風險。2027-2028 年的具體財務或產能數字公開資料不足,以上為依公司策略、法說與產業供需資料所作之研究推估。

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.
