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)
0-20 285+24.6% +14.9% 73.3% +8%
20-40 132+27% +28.7% 75.8% +19.9%
40-60 86+61.9% +68.7% 90.7% +51.6%

80-100 701+21% +19.4% 74.5% -5.6%

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 ≈ 34.13, at the 72.9th percentile of its own history (60-80 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

蔚華科定位為半導體設備專業經銷代理商、系統整合與自有檢測設備開發商,扮演上游設備供應商與下游 IC 設計、晶圓製造、封裝測試及其他高科技製造客戶之間的橋樑。公司與子公司營收主要來自半導體和積體電路設計、封裝、測試、檢測分析設備之代理銷售與維修服務,以及相關進出口、代理、報價、投標與經銷業務。2024 年主要產品營收比重為:半導體設備 642,590 仟元、占 95.44%;勞務收入 11,098 仟元、占 1.65%;維修收入 18,609 仟元、占 2.76%;其他營業收入 976 仟元、占 0.15%。銷售區域方面,2024 年國內銷售 224,251 仟元、占 33.31%;國外銷售 449,022 仟元、占 66.69%,國外以中國大陸為主。主要商品與服務包括 IC 測試機、全自動晶圓針測機、Handler、測試介面、探針卡、測試座、繼電器、測試印刷電路板、晶圓材料、封裝製程設備、晶圓級迴焊、電漿清洗、混合鍵合、翹曲校正、熱拆鍵合、AOI 與缺陷檢測設備、失效分析與材料分析設備、板卡維修與客製化軟硬體整合。公司核心事業分為專業經銷服務、整合型服務、自有產品開發與生產製造;商業模式是代理國外原廠設備、提供在地安裝維修與技術支援、替客戶整合硬體與軟體測試方案,並逐步提高自有 SpiroxLTS 雷射斷層掃描、TSV/TGV 非破壞檢測、SiC/GaN 缺陷檢測、矽光子波導檢測等產品占比。終端應用涵蓋電源管理、類比與混合訊號、SoC、RF、微控制器、無線通訊、顯示控制器、功率半導體、化合物半導體、AI/HPC 先進封裝、CoWoS、CPO、矽光子、MicroLED 等。

Outlook 2025–2028

2025 至 2028 年展望以自有檢測技術商業化與先進封裝需求為主軸。公司 2024 年報之 2025 年營業計畫指出,蔚華科已於 2023 年第四季在晶圓代工廠安裝兩套矽光子 WAT 檢測解決方案,2024 至 2025 年持續擴大推向不同 OSAT 與應用端客戶;2025 年初推出 SP8000G 非破壞性雷射改質檢測系統與 SP8000S 非破壞性 TSV 檢測系統,以 SpiroxLTS 雷射斷層掃描與 3D 成像取得晶圓孔徑、孔壁微小缺陷等資訊,目標改善 TGV/TSV 設計與製程、提升 CoWoS 與先進封裝品質和產能。公司也在化合物半導體領域打造 SiC 基板非破壞性缺陷檢測系統,並與 NI/Emerson 相關技術資源合作建置功率半導體動態可靠度驗證實驗室,鎖定車用功率半導體與 SiC/GaN 應用。成長動能包括生成式 AI、HPC、雲端資料服務推升先進封裝和 OSAT 中長期產能需求;玻璃基板、TGV、TSV、HBM、CoWoS、CPO、矽光子、MicroLED、超穎材料等新技術提高檢測與製程驗證門檻;中國大陸、東南亞、歐美市場若能打開,將有助降低對單一區域代理業務的依賴。風險與挑戰包括:2024 年仍處虧損,轉型自有設備能否放量仍需驗證;設備銷售受半導體景氣與客戶資本支出循環影響大;中國大陸半導體供應鏈景氣與地緣政治、關稅、出口管制可能影響接單與交貨;TSV/TGV、玻璃基板、矽光子與功率半導體驗證雖具題材,但量產導入時程、客戶認證、良率改善效益與價格競爭仍存在不確定性;同時公司需面對歐美、日韓原廠設備商與台灣檢測分析服務商的競爭。2026 至 2028 年公開資料未見公司正式量化財測,本段屬依公開年報、公司新聞與產業趨勢所作之中期推估。

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.
