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 ≈ 260.32, at the 100.0th 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.

Business

雷科早期以SMD表面黏著元件封裝材料與SMT相關設備起家，現已轉向材料與設備雙核心。主要產品包括SMD晶片封裝紙帶、上下膠帶、半導體封裝材料如Emboss cover tape與Embossed carrier tape；SMT雷射雕刻、條碼雕刻、AOI與檢測相關設備；陶瓷基板雷射劃線、鑽孔、切割機；厚膜與薄膜雷射調阻機、Chip Trimmer、Function Trimmer、軟板與硬板切割、FR4/FR5載板切割、晶圓修整、Wafer Marking、雷射除膠、TSV/TGV鑽孔與SiC切割等。2024年營收結構為捲裝材料454,801仟元、占33.41%；自製雷射設備及代理設備898,492仟元、占66.01%；能源及其他7,891仟元、占0.58%。商業模式包含自製Laser Tek品牌雷射設備、代理德國SMT/CoWoS檢測設備、SMD封裝材料加工與銷售、客製化設備開發與售後服務。年報指出2024年內銷營收794,712仟元、占58.38%，外銷566,472仟元、占41.62%；外銷主要在亞洲。主要終端應用涵蓋被動元件、半導體先進封裝、IC載板、PCB/FPC、光電、AR/VR、車用電子、AI伺服器與HPC供應鏈。公司未公開完整客戶名單，年報僅說明自製雷射設備客戶以被動元件、光電、半導體產業為主，對象為台、日系客戶及中國大陸廠商，2024年內銷增加主要來自半導體與光電台廠的SMT代理設備與自製雷射設備出貨增加。

Outlook 2025–2028

2025至2028年展望核心在半導體先進封裝與雷射製程設備滲透率。成長動能包括：AI/HPC晶片推升CoWoS、2.5D/3D先進封裝產能需求；公司代理SMT檢測設備已被運用於CoWoS製程；自製雷射設備布局前段TSV/TGV鑽孔、SiC切割、Wafer Trim、Functional Trim，中後段封裝雷射切割、除膠、檢測等；2024年年報規劃密集孔鑽孔機、高精度複合板切割、Lead Frame EMC二合一雷射加工、AI晶片雷射除膠機等新產品，並預估2025年度研發費用約55,000仟元、約占營收3.5%。近期產業報導指出，2026年半導體設備在手訂單與出貨能見度延續，設備營收占比已逾60%，代理德國Cyber Tech的CoWoS先進封裝檢測設備及自製雷射設備為主要觀察項目。中期至2028年，若AI晶片、先進封裝、玻璃基板、IC載板與車用/光電應用維持投資，雷科有機會受惠於設備認證通過、客戶擴產與產品組合轉佳。不過風險包括：2025年部分CoWoS設備遞延造成營收與獲利波動；2026年第1季EPS僅0.06元，顯示訂單認列節奏與費用吸收仍不穩；SMD封裝材料面臨中國供應商低價競爭；紙帶等部分原材料仰賴日本及中國大陸供應，匯率與供應失調可能影響成本；先進封裝設備需經客戶長期驗證，若認證進度、客戶資本支出或AI需求不如預期，成長假設將下修。2027至2028年的量化營收與獲利目標未見公司正式財測，僅能以產業趨勢與訂單報導作中性推估。
