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)
0-20 163+21.2% +18.9% 98.2% -1.8%

80-100 You are here668+3.8% -14.4% 44% -19.9%

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 ≈ 1057.5, at the 99.9th 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

公司定位為材料科學公司,以高分子、精密塗佈、射出與押出、光學、精密雕刻、捲對捲製程為核心,產品橫跨機能膜、先進電池材料、生醫與織物。2025 年合併營收 178.45985 億元,年減 4%;內銷 53.22535 億元、占 29.8%,外銷 125.23450 億元、占 70.2%,其中亞洲外銷占 63.7%。主要業務之一為顯示材料/機能膜,核心產品為偏光片及機能膜,應用於 LCD、OLED、液晶電視、桌上型顯示器、平板、筆電、手機、穿戴、工控與專業顯示器;公司在偏光片製程涵蓋 PVA 染色、TAC 蝕刻/貼合、保護膜貼合、裁切、磨邊、熟成與包裝等。另一主軸為醫療/護理產品,包含隱形眼鏡、皮膚護理、傷口照護、醫療包材、專業衛材與低溫膜材等;法說與媒體資料顯示醫療事業 2024 至 2025 年占比約三成,2025 年機能膜與醫療產品營收占比約 67% 與 33% 為法人/媒體估計,非年報正式產品別表。年報揭露 2025 年主要銷貨客戶甲占銷貨 27%,且為關係人,但未揭露名稱;主要供應商甲、乙分別占進貨約 20%、10%,名稱亦匿名。

Outlook 2025–2028

2025 年公司營運由盈轉虧,全年營收 178.46 億元、毛利率約 14%、歸屬母公司淨損 3.64 億元、EPS -1.14 元,主因顯示器材料需求走弱、新台幣兌美元升值與毛利壓力;醫療與高附加價值產品仍維持成長但不足以完全抵銷顯示材料衰退。2026Q1 合併營收 45.46 億元,受顯示器材料壓力影響仍虧損,惟虧損較 2025Q4 收斂。2025 至 2028 展望可分為四條主線:第一,顯示器材料由一般偏光片走向高值化,重點在車用顯示、OLED 手機、大尺寸電視、高耐候、薄化、低碳材料與高抗眩低反射產品;車用顯示器因認證與供應鏈黏著度較高,預期相對穩定,但 IT、手機與 TV 終端需求仍受景氣、記憶體成本與面板循環影響。第二,醫療事業是中期主要成長引擎,公司目標 2026 年醫療業務恢復雙位數成長,產品線包括消費性醫療(隱形眼鏡、皮膚護理)與專業醫療(傷口敷料、醫療包材、手術應用材料),市場聚焦台灣、中國、東南亞並逐步拓展歐美;醫療產品認證期長、進入門檻高,一旦導入較不易被替換,但也代表新產品放量節奏較慢。第三,新興材料布局包括半導體製程材料、CMP 製程後清洗刷輪、Micro LED 移轉膠材與防漏光膜材、CPO 光通訊用 FAC 快軸準直透鏡及光學膠材,多數仍屬開發、小量出貨或客戶共同驗證階段,2027 至 2028 是否形成實質營收貢獻仍待觀察。第四,風險包括中國偏光片新增產能與價格競爭、PVA/PET/補償膜等上游寡占材料供應與成本波動、日圓/美元/新台幣匯率、醫療保險價格壓力、高階醫材取證與客戶驗證週期、主要客戶集中、以及總體景氣與關稅不確定性。

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.
