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)

80-100 251+29.3% +21.6% 57.8% +2.6%

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 ≈ 79.13, at the 49.2th 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

公司定位為傳動控制與系統科技、機電元件及高精密次系統製造商，核心技術為高階傳動、運動控制、直驅馬達、伺服驅動器、控制器、位置量測與微米/奈米級定位系統。2024年營收結構為：精密運動及控制元件12.26039億元、占54.40%，產品含控制器、驅動器、線性馬達、直驅馬達、真空馬達、力矩馬達、伺服馬達、線性致動器、位置量測系統；微米與奈米級定位系統10.04843億元、占44.59%，產品含單軸、雙軸、龍門、橋式、空氣軸承、多軸及客製化定位平台；其他0.22825億元、占1.01%。2024年合併營收22.53707億元、年增4%，稅後淨利0.90940億元。2025年公司揭露合併營收27.14367億元、較2024年成長20%，稅後淨利2.59924億元。2026年前5月自結累計營收15.32483億元、年增44.82%。商業模式以自製關鍵元件、機電整合、客製化定位平台與售前/售後技術支援提供設備廠一站式解決方案，銷售區域以外銷為主，2024年外銷占84.38%，其中亞洲63.72%、歐洲16.71%、美洲3.62%，內銷15.62%。下游應用包括半導體設備、先進封裝、晶圓檢測、PCB/AOI檢測、FPD設備、SMT設備、雷射加工、工具機、自動化搬送、機器手臂、電動車、太陽能、高階醫療與智慧製造。年報揭露2024年銷貨前兩大客戶以匿名甲客戶與乙客戶呈現，分別占29.13%與25.93%，其中乙客戶為其他關係人。

Outlook 2025–2028

2025年已受惠AI、高速運算、半導體先進製程與先進封裝需求，全年營收年增20%，稅後淨利大幅改善。2026年前5月自結營收年增44.82%，顯示半導體設備、精密定位與高階驅控需求延續。公司展望重點包括：一、半導體CoWoS、FOPLP、玻璃基板封裝、晶圓移載、加工製程、缺陷檢測與關鍵尺寸量測對奈米級定位平台及高響應驅控器需求提高；二、2026年上架多維度定位平台MD-ZT，搭配高階驅控器，訴求高動態特性、奈米級伺服穩定性與模組化降本；三、E系列驅動器支援EtherCAT、Profinet與EtherNet/IP，擴大智慧自動化與全球設備整合相容性；四、公司持續開發多軸驅動模組、奈米精密定位多軸控制器、大推力水冷式線性馬達、超高精度Z軸多自由度定位模組，並提升水冷式馬達、節能減碳型線性馬達、高精度絕對式直驅馬達、高性能E2 400V驅動器、高動態半導體精密定位平台等產品；五、2026至2028年成長動能可望來自AI/HPC帶動的先進封裝資本支出、全球製造業自動化、電動車與新能源設備、高階醫療與智慧物流。主要風險包括全球資本支出循環、半導體設備訂單波動、德日美中品牌競爭與中國同業價格競爭、地緣政治與貿易政策、ECFA或關稅變動、匯率、原物料與電子零組件供應、客戶集中度偏高，以及氣候變遷與淨零要求造成的供應鏈短期波動。2027至2028年未見公司公開量化財測，以上為根據公司公開展望與產業趨勢之推估。

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.

This page is historical statistics for educational purposes and is not investment advice. Investing involves risk; past performance does not indicate future results. Assess and bear the risk yourself before trading.
