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)
0-20 184+25.8% +25.1% 99.5% +3%
20-40 191+30.7% +18.4% 76.4% +8.7%

80-100 You are here851+23.1% -7.7% 40.4% +14%

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 ≈ 931.43, at the 98.3th 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.

Overview

4919 對應證券為新唐科技股份有限公司,為台灣證券交易所上市普通股。公司成立於2008年4月9日,2008年7月由華邦電子邏輯IC事業群分割成立,2009年12月15日公開發行,2010年1月29日登錄興櫃,2010年9月27日上市。總部位於新竹科學園區研新三路4號。董事長為蘇源茂(Yuan-Mou Su,華邦電子代表人),總經理為楊欣龍(Hsin-Lung Yang)。截至2026年3月9日年報資料,普通股已發行419,765,268股,實收資本額約新台幣41.98億元。2025年底員工數3,723人,2026年3月9日為3,713人,其中工程技術人員約2,521人。主要股東為華邦電子股份有限公司持股221,554,635股、52.78%,第二大股東為勤新投資股份有限公司持股5,440,219股、1.30%,其餘前十大多為外資保管帳戶、指數基金、勞退基金與自然人。公司在美國、中國、以色列、印度、韓國、新加坡、日本、德國設有子公司或據點。2025年合併營收約新台幣304.924億元,稅後淨損約16.646億元,每股虧損3.97元,主因包括日本產能投資利用率不如預期、汽車產品受主要客戶庫存調整影響,以及關稅與成本不確定性。

Business

新唐主要從事積體電路研發、設計、銷售與半導體晶圓代工服務,並提供從設計、系統整合、製造到市場導入的客製化完整解決方案。2025年營收結構為IC產品收入新台幣282.407億元、占93%;晶圓代工服務收入16.568億元、占5%;其他收入5.949億元、占2%。主要產品包括MCU/MPU、音訊SoC、音訊強化/轉換/放大晶片、I/O晶片、筆電嵌入式控制器EC、伺服器BMC、TPM可信平台模組、高速傳輸晶片、MOSFET、訊號處理晶片、影像感測器、電池監測IC、馬達驅動/控制IC、NFC Tag晶片與6吋晶圓代工服務。主要市場涵蓋工業控制、車用電子、通訊、消費電子、電腦、資料中心、伺服器、邊緣運算、智慧家電、AIoT、電動車/儲能與智慧終端。2025年銷售地區以亞洲為主,亞洲營收約295.898億元、占97%,歐洲約5.261億元、占2%,美洲約3.765億元、占1%。商業模式上,IC事業以自有設計與平台化解決方案銷售給品牌客戶、系統廠、模組廠、ODM/OEM與區域代理通路;晶圓代工則利用自有6吋廠及特殊製程提供小量多樣、客製化與高壓/功率相關製程服務。公司亦強調與母公司華邦電子記憶體產品搭配MPU方案,以縮短客戶開發時間與降低系統成本。客戶名稱多未公開;年報揭露單一Client V於2025年貢獻約新台幣60.935億元、占營收20%,但未揭露實名。

Outlook 2025–2028

2025年為營運壓力年,全年虧損,主要受到全球總經與關稅不確定性、日本產能利用率偏低、車用客戶庫存調整、一般產品供應鏈成本壓力與成熟製程需求轉移影響。2026至2028年的核心觀察重點包括:一、AI伺服器與資料中心需求推動BMC、SMC、TPM、OpenTitan安全晶片、48V伺服器風扇馬達驅動、伺服器備援電池BBU用BM-IC與電源管理相關產品成長;公司2025年已推出Arbel SiP BMC NPCM8mnx並通過OCP S.A.F.E.認證,48V馬達驅動已量產出貨給台灣主要電源供應商並瞄準全球一線雲端服務商與伺服器品牌。二、端點AI與AIoT推動AI MCU M55M1、NuML Toolkit、音訊AI、語音辨識、工業閘道與智慧家電應用;公司稱新一代AI MCU可提供約110 GOPS算力,並以軟硬體平台與第三方演算法降低開發門檻。三、車用電子方面,第四代Gerda車用HMI顯示晶片已進入量產,可用於電子後視鏡、AR HUD與電子儀表;BMIC已開始對美系車廠量產出貨,並以25通道第四代BMIC支援800V電動車平台;ToF感測器取得ASIL-B功能安全認證,後續受DMS/OMS、Euro NCAP 2026安全規範與座艙數位化趨勢帶動。四、晶圓代工方面,6吋成熟製程面臨8吋/12吋替代與需求弱化,公司策略是轉向高壓、功率元件、馬達驅動、PMIC、工控與車用特殊製程;2026年與Tower Semiconductor策略重組後,新唐取得8吋晶圓廠100%控制權、Tower持有12吋廠,預期有助降低12吋產能負擔並提升車用/工業產品自主產能與製程彈性。五、長期地緣與供應鏈重組下,公司將擴大亞洲市占並深入歐美與東南亞,在德國、美國、印度等地強化在地銷售與技術支援。主要風險包括:AI伺服器題材是否能轉化為可觀營收與毛利、BMC與安全晶片競爭、成熟MCU價格戰、車用導入週期長且受客戶庫存波動影響、6吋廠轉型速度、8吋廠整合與稼動率、原物料與記憶體成本、匯率、利率、關稅政策、地緣政治與中國/歐美半導體政策變化。2027至2028的量化財務預測未由公司正式公告,故不列具體營收或獲利目標。

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.
