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.

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)

80-100 You are here146-0.9% -5.8% 43.2% -16.4%

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 ≈ 32.56, 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.

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.

Does this signal hold up across the market

Over the past 242 months, on average ~404 stocks per month met “monthly revenue YoY ≥ 20%”; their adjusted-close return over the next 60 trading days averaged 6.94% (equal-weighted), beating the market by 2.37 points on average, and outperformed the TAIEX total-return index in 64.5% of months.

Each month, equal-weighted 60-day forward adjusted return of all signal-matching stocks, then averaged across months; excess vs the TAIEX total-return index.

Overview

3357 對應證券為西北臺慶科技股份有限公司，股票簡稱臺慶科，為櫃買中心上櫃普通股，非 ETF、ETN、權證或特別股。公司前身可追溯至 1975 年成立之西北電機，1992 年 11 月 2 日成立臺慶精密電子，2000 年與西北電機合併為西北臺慶科技股份有限公司，2021 年 4 月 27 日掛牌上櫃。總部位於桃園市楊梅區幼獅工業區幼四路 1 號。董事長為謝明諺，總經理為謝明良。公開資訊彙整顯示資本額約新台幣 11.06 億元，已發行普通股約 110,592,565 股，含私募 7,000,000 股；2025 年引進台灣柏恩氏電子股份有限公司/Bourns Electronics 以每股 114.1 元認購私募 700 萬股，估持股約 6% 至近 7%，成為重要策略股東之一。2025 年第三季法說資料列示生產據點為台灣桃園、江蘇昆山、江蘇泗洪與馬來西亞新山；員工約台灣 500 人、中國 1,750 人、馬來西亞約 50 人，合計約 2,300 人左右，另公司簡報頁面以 2,250 人呈現。2024 年營收為新台幣 55.06 億元，2025 年前三季營收 48.18 億元，年增約 20.1%，前三季 EPS 7.84 元；新聞彙整顯示 2025 全年合併營收約 66.25 億元，年增 20.32%，並創歷史新高。主要股東完整前十大持股需以最新年報或股東會資料為準；可確認的重要股東/法人包含經營團隊相關投資公司與 2025 年私募策略股東 Bourns，但未在公開可擷取來源中完整核對最新前十大名單。

Business

臺慶科為磁性材料與電感元件製造商，主要從事被動元件電感之研發、製造與銷售，核心產品包括積層晶片磁珠/電感、共模濾波器、網路濾波器、訊號電感、繞線電感、一體成型功率電感、TLVR/高效能功率電感、網路變壓器等。公司具垂直整合能力，從氧化鐵、合金、陶瓷等材料配方到積層、繞線、一體成型、封膠與組裝製程皆有布局；官方法說資料稱擁有 40 種以上材料配方。2025 年第三季產品營收占比約為電源電感 62.9%、共模/網路濾波器與訊號電感 18.6%、積層晶片電感/磁珠 18.5%；2024 年全年產品占比約為電源電感 62.1%、共模/網路濾波器與訊號電感約 17.9% 至 20.1%、積層晶片電感/磁珠約 20.1%。應用別方面，2025 年第三季公司資料顯示車用電子 38%、PC 相關 24%、AI 相關 10%、通訊 16%、消費性 11%、其他 1%；相較 2024/2023 年，AI 與車用占比提高。商業模式以自有研發、材料配方、製程量產與客製化規格供應為主，透過直接客戶、代理商與 OEM/ODM 供應鏈出貨。終端應用涵蓋車用 ADAS、雷達、鏡頭、車身控制、EV/HV、電池管理、車用乙太網路、AI 伺服器、雲端伺服器、DDR5 記憶體、PC/NB、網通交換機/路由器/5G 基站、IoT 與消費性電子。客戶名稱多未公開；公開報導稱公司為多家全球 Tier 1 車廠與北美雲端服務供應商供應鏈認證廠商之一，並與國內電源大廠合作開發 800V HVDC 相關高功率變壓器與電感元件。生產布局方面，2025 年第三季法說資料列示泗洪產值比重約 73%、台灣約 16%、昆山約 11%，馬來西亞新山廠於 2025 年開始量產，主要產品規劃含共模濾波器、網路變壓器與電源電感，用於分散中國產能與支援車用、AI 及美系客戶需求。

Outlook 2025–2028

2025 至 2028 年主要成長動能包括：一、AI 伺服器與高速運算。公司已切入 GB200/GB300、CSP ASIC 架構 AI 伺服器與 TLVR/高效能功率電感等需求，AI 相關營收占比由 2025 年約 10% 逐步提升，部分報導預期 2026 年可再提高；AI 伺服器功耗提升、電源架構升級、散熱與高速傳輸增加，都有利高電流、高效率、小型化電感用量。二、800V HVDC 與資料中心電源架構。公司表示與國內電源大廠合作開發 800V HVDC 所需高功率變壓器與電感元件，預期 2026 年後逐步發酵；若 AI 資料中心高壓直流配電滲透率提升，單價與規格門檻有機會優於傳統產品。三、車用電子。車用仍為公司最大應用之一，2025 年第三季占比約 38%，涵蓋 ADAS、車用乙太網路、EV/HV、BMS、車身控制、LED 車燈等；IATF 16949 與全球 Tier 1 供應鏈認證有助維持中長期訂單能見度。四、DDR5、AI PC/NB 與高階 PC 換機潮。DDR5 滲透率與 AI PC/NB 換機將提升電感數量與規格，支撐 PC 相關應用。五、馬來西亞廠與非中國產能。新山廠 2025 年量產，市場報導稱已通過美系大廠稽核或朝車規認證推進，可分散地緣政治與關稅風險，並承接美系/車用/AI 客戶非中製造需求。六、價格與轉單。2026 年市場報導指出日系電感廠調漲磁珠、功率電感、RF 電感，銀價與原材料成本上升也推動報價調整；臺慶科可能受惠轉單與產品價格改善。主要風險包括：AI 與 HVDC 專案導入時程不確定、客戶認證與放量節奏可能遞延；銀、銅、氧化物、合金粉末與導電漿價格波動壓縮毛利；日系、美系、台系與中系電感廠競爭激烈；中國生產比重仍高，面臨地緣政治、關稅、客戶非中化要求與匯率風險；車用產品驗證期長且品質責任高；若 AI/PC 換機潮低於預期，估值與庫存循環可能修正。2027 至 2028 年屬中長期推估，公開資料多未提供公司量化財測，需持續追蹤馬來西亞廠稼動率、AI/HVDC 訂單占比、車用認證進度、月營收與毛利率變化。

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.
