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)
0-20 423-17.2% -18.5% 22.5% -37.8%
20-40 You are here173+25.8% -43.3% 19.7% +16.3%

80-100 364+68.3% -4.8% 45.3% +42.8%

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 ≈ 22.29, at the 36.2th percentile of its own history (20-40 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

敦泰為人機介面解決方案 IC 設計公司,業務為顯示驅動、觸控、指紋等人機介面解決方案之開發及銷售,並包含軟硬體設計、製造、諮詢與服務。2024 年報揭露主要產品銷售以 TDDI/IDC 觸控與顯示驅動整合晶片、外掛式電容觸控 IC、TFT-LCD 驅動 IC、指紋辨識 IC 為主;另有 AMOLED 面板驅動晶片、車載與工控晶片、NB 觸控板、觸控與指紋整合模組及生理監測相關產品。營收結構方面,2024 年人機介面應用晶片為 100%;銷售區域為中國大陸新台幣 119.11265 億元、81.93%,台灣新台幣 23.28160 億元、16.01%,其他地區新台幣 2.99562 億元、2.06%,合計新台幣 145.38987 億元。商業模式屬無晶圓廠 IC 設計,生產製造委外;公司透過經銷商、手機模組廠、面板廠銷售,也供應中國大陸手機市場及日本主要手機品牌。終端應用包含智慧手機、平板、筆記型電腦、穿戴裝置、數位相機、車載顯示、工控、智慧門鎖及生理監測裝置。公司 2024 年 IDC 出貨量超過 2 億顆,年報預期 2025 年 IDC 出貨量與市占率續增;2025 年全年營收公開資料約新台幣 119.52 億元、年減 17.79%,顯示手機與價格競爭壓力仍大。

Outlook 2025–2028

2025 至 2028 年主要觀察軸為產品組合升級與應用市場擴張。成長動能包括:一、IDC/TDDI 在手機、平板與車載顯示導入,敦泰年報稱 2024 年 IDC 出貨超過 2 億顆,並預期 2025 年出貨與市占率持續提升;二、AMOLED 相關觸控與驅動方案,包含剛性 on-cell、柔性 on-cell、中大尺寸 AMOLED 觸控方案、LTPO 動態幀率、Demura、De-Burn In、CUP 等技術;三、車載顯示與智慧座艙,年報指出車內螢幕朝多屏、大尺寸、一字屏及 Pillar-to-Pillar Display 發展,In-Cell 解決方案占比提升,公司開發車用 IDC、串接架構及高可靠度電路;四、筆電與指紋辨識,敦泰 MOC 指紋方案獲 Microsoft 認證,並切入筆電、智慧門鎖與觸控板整合模組;五、生物感測與醫療級生理監測軟硬體可作為長期選擇權。產業趨勢上,5G 手機滲透率、AMOLED 滲透率、車用顯示大尺寸化、AI 強化生物辨識演算法、IoT 與工控觸控需求有利於高整合 IC。主要風險包括中國 IC 設計同業價格競爭、TDDI 與車用 TDDI 降價壓力、智慧手機需求波動、AMOLED 與車用新品認證週期長、客戶導入不確定、委外晶圓代工與封測供應彈性、美元匯率波動、研發費用維持高檔,以及 2025 年虧損後仍配息與庫藏股對資金配置的壓力。2026 至 2028 的數字化財測未見公司正式長期指引,本欄為依年報產品計畫、法說新聞與產業趨勢所作之研究判斷。

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.
