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 1250+18.1% +3% 53.1% +6%
20-40 764+19.3% +17.4% 68.1% -0.1%

80-100 133+7.2% +7.7% 87.2% -27.3%

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 ≈ 17.24, at the 53.3th percentile of its own history (40-60 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

義隆為人機介面 IC 設計公司,核心產品為觸控螢幕晶片、帶筆功能的觸控螢幕晶片、觸控板模組、指向裝置 Pointing Stick、生物辨識晶片(含指紋與人臉辨識)、微控制器與 AI 影像辨識相關方案。2024 年報揭露 2024 年主要業務及營業比重為:筆電輸入裝置模組新台幣 91.12 億元、占 71.78%;消費性觸控積體電路新台幣 32.19 億元、占 23.16%;其他新台幣 3.65 億元、占 5.06%;合計新台幣 126.96 億元。商業模式以 IC 設計、韌體與模組方案開發為主,製造端採晶圓代工、封裝測試與模組組裝等專業分工,部分產品同時提供模組化解決方案以提升單價與客戶黏著度。應用以筆記型電腦為大宗,涵蓋 Touchpad、Touchscreen、指紋辨識、Copilot Key 整合指紋與導航、Pointing Stick、Chromebook SLOC 觸控、Haptic 觸覺回饋觸控板等;非筆電應用包括電子紙主動筆、車用及工控觸控、車用顯示器 TDDI、Mini LED 區域調光控制、智慧卡指紋辨識、智慧調光玻璃、ADAS Level 1/2+、智慧交通 ITS、無人機物件偵測追蹤與避障等。客戶以全球非蘋筆電品牌、商務筆電與高階機種供應鏈為主,市場文章與產業報導列舉宏碁、華碩、Lenovo、HP、Dell、Samsung、Microsoft、Google 等為合作或終端品牌;公司年報亦強調與重要客戶共同開發 AI PC 市場,但未在年報逐一揭露所有客戶名稱。

Outlook 2025–2028

2025 至 2028 年展望偏向「筆電換機週期加規格升級」與「AI 非筆電應用擴張」雙軸。2025 年公司年報指出,Windows 10 停止更新可能帶動商用筆電換機潮,Omdia 預估 2025 年筆電出貨量年增中至高個位數、達約 1.96 億台;義隆將與客戶開發 AI PC 市場,並推進 AI 及手指/手掌識別強化觸控板、壓感回饋觸控板、Chromebook SLOC、防水手套與主動筆功能、智慧座艙顯示器、ADAS 影像處理、車用觸控驅動整合、智慧卡指紋辨識與 GaN 充電器驅動晶片。2026 年法說相關報導指出,公司預期 AI 產品占比由 2025 年約 5% 提升至雙位數,並朝 15% 至 20% 邁進;筆電相關應用仍逾 85%,商務機種占比提升,Haptic、SLOC、高單價 MOC 指紋、Copilot Key 整合方案等有助 ASP 及產品組合。2026 至 2028 年的合理推論是:AI PC 滲透率提升、商務筆電資安需求、觸控板尺寸放大、Haptic 滲透、SLOC 與主動筆應用、車用及工控觸控、ADAS、智慧交通、無人機與智慧卡等可提供中長期成長來源;竹北新廠預計 2026 年完工,屬綠建築及智慧建築,主要強化營運與研發空間,並非高資本支出的晶圓製造產能。主要風險包括:全球 PC 需求低於預期、品牌提前拉貨後庫存修正、關稅與地緣政治、記憶體或晶圓代工成本波動、客戶導入 AI PC 與非筆電應用時程延後、Synaptics、敦泰、匯頂、神盾等競爭、專利訴訟、匯率及業外評價損益波動、車用與智慧交通專案認證及量產週期較長。2027 至 2028 的數字化營收或獲利目標公司未公開明確指引,本段屬依年報、法說資料與產業趨勢做出的定性推估。

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.
