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 97+55.7% +54.3% 100% +30%
20-40 201+38.9% +44.5% 78.1% +12.9%

80-100 You are here44-13.6% -14.2% 0% -26.5%

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 ≈ 2875.0, at the 98.4th 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

公準以精密模具設計製造、精密機械加工、表面處理、組裝與測試能力為核心,供應高科技製程設備與航太應用之關鍵零組件,商業模式以依客戶圖面、規格與認證要求進行少量多樣、高精度客製化製造為主。2024 年營收結構依年報為:半導體類 61.67%、顯示器設備類 19.68%、航太類 15.78%、能源類 0.14%、其他 2.73%。2025 年前三季法說資料顯示半導體約 59%、顯示器設備約 30%、航太約 10%、其他約 1%,顯示器占比回升而航太受客戶拉貨週期影響下滑。主要產品包括半導體微影製程設備關鍵零組件、良率檢測設備零組件、電子束檢測設備零件、IC 封裝工模夾治具、CVD/PVD/OLED 顯示器設備腔體與零組件、航空伺服閥與致動器相關零組件、起落架致動器零件、發電與微渦輪引擎零組件。公開媒體指出主要合作或客戶包含 ASML、Applied Materials、日月光投控、群創、友達;年報則以甲乙丙丁戊代號揭露主要銷貨客戶,2024 年前五大客戶占比分別約 18.52%、13.66%、22.86%、11.23%、10.19%,客戶集中度偏高。

Outlook 2025–2028

2025 年公司營運受終端設備需求下修與客戶拉貨週期影響,全年營收約 12.57 億元、年減約 4.37%,稅後轉虧,EPS 約 -0.46 元;2026 年初營收已有回升跡象,2026 年 3 至 5 月單月營收分別約 1.43 億、1.15 億、1.20 億元,但獲利仍需觀察毛利率與稼動率恢復。2025 至 2028 年主要成長動能包括:半導體先進製程與先進封裝設備零組件需求,尤其微影、檢測、封裝模具與高精度次組裝產品;與荷商半導體設備大廠、德商光學雷射設備大廠、美國國際大廠合作開發高精度零件;顯示器領域切入新世代 OLED 設備零件;航太方面受惠航空客運復甦、波音與空巴機型零件需求、致動器與伺服閥零組件、衛星系統反應輪與反射鏡等新產品。公司高科廠規劃以半導體與航太產能為主,公開報導稱預計 2026 年第 3 季啟用,若順利量產可支撐 2027 至 2028 年接單與在地化商機。主要風險包括客戶集中度高、半導體設備資本支出循環波動、航太認證與拉貨週期長、OLED 景氣仍低迷、原物料如鈦合金與不鏽鋼價格波動、國際貿易與地緣政治、匯率、擴產時程與新產品良率不確定性。

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.
