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.

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 ≈ 78.65, at the 90.7th 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

3167 對應證券為大量科技股份有限公司，為台灣證券交易所上市普通股。公司成立於1980年12月26日，總部位於桃園市八德區豐田路68號，前身為大量工業股份有限公司，2000年8月更名為大量科技股份有限公司，2004年4月19日登錄興櫃，2013年10月21日轉上市。董事長為王作京，總經理為簡禎祈，發言人為林德錚。實收資本額約新台幣8.85億元，已發行普通股約8,850.5萬股。官方主要股東資料揭露日為113年5月30日，前十大或持股逾5%股東包含山林投資股份有限公司、鄭天薌、王作京、李在為、李秀香、李宜軒、李宜珊、能華維國際股份有限公司、陳賜義、陳秋葵；另鉅亨網較近期董監事經理人持股頁面顯示王作京、鄭天薌仍為主要自然人持股者。員工總人數未在本次可查證來源中取得明確最新數字；Goodinfo揭露2025年全體員工平均薪資約73.8萬元，但此不等同員工規模。

Business

大量科技為專業設備製造商，核心業務包括PCB設備、CNC彫銑機械、半導體量測與檢測設備。公司官網說明其提供晶片/晶圓檢查、PCB成型、PCB鑽孔、薄板切割、玻璃面板加工等專用機械，並具備機械設計開發、製造組裝、品檢測試、銷售服務能力。PCB設備包含PCB成型機、PCB鑽孔機、CCD深控/背鑽相關機種、電路板內層深度量測機、自動化單軸鑽孔機等；產品特點包含PC-Based控制器、自行開發控制軟體、多軸高速運動控制、CCD影像定位、盲鑽、深度補正、即時斷刀偵測、MES通訊與設備監控等。半導體設備包含CMP Pad即時量測監控、SOH量測、Bonding Wafer Edge量測、Molding厚度量測、Wafer Step Height量測、面板級封裝翹曲/厚度量測、AOI與自動化系列等，用於晶圓、晶片、封裝製程量測與外觀缺陷檢查。MoneyDJ整理之2024年營收結構為PCB/半導體設備約94%、其他約6%；銷售地區為台灣約17%、亞洲約83%。公司商業模式以客製化與標準化設備銷售、售後服務、控制器與製程應用軟體能力形成設備差異化，主要終端應用涵蓋AI伺服器高階PCB、高頻高速通訊板、光模組、mini LED、BGA載板、3D IC與先進封裝等。

Outlook 2025–2028

2025至2028年展望核心在AI伺服器、高速網通、光通訊與先進封裝帶動的高階設備升級。2025年公司營收與獲利已顯著跳升；鉅亨網報導2025年營收50.78億元、毛利率39.17%、稅後純益7.16億元、EPS 8.13元，擬配發現金股利4元。成長動能包括AI伺服器PCB層數、厚度、訊號完整性要求提升，使背鑽、深控、內層深度量測、高精度成型與鑽孔設備需求增加；高階設備占比由10%至20%提升至約30%。產能方面，報導指出公司在桃園八德、大陸南京、漣水等據點生產，南京廠擴充後含外包之每月PCB鑽孔機最大產能約350台，目標再推升至約400台，以因應PCB廠擴產。2026年能見度方面，鉅亨網與富果法說整理均指出訂單強勁，部分資料稱排程可見至2026年9至10月或更長；此部分屬公司法說與媒體轉述，需持續以公司公告驗證。半導體端，公司積極發展CMP、3D IC、面板級封裝、先進封裝量測與AOI設備；市場報導亦提及半導體事業規劃分割至大量先進智能，分割後仍為100%持股子公司，未來可能利於專注研發、募資與人才激勵。2027至2028年若AI伺服器、1.6T/3.2T光通訊、CoWoS/FOPLP/玻璃基板等高階封裝與高速PCB投資延續，設備需求具延續性；但風險包括PCB資本支出循環反轉、客戶驗證與交機遞延、中國與海外設備商價格競爭、關稅與地緣政治、匯率、零組件供應、半導體設備驗證週期長、股價已高度反映成長預期，以及媒體報導客戶/訂單能見度未必等同確定收入。

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.
