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 0Insufficient data
20-40 160-2.3% -3.5% 45.6% -35.9%

80-100 You are here218+52.3% +58.7% 86.7% +8.1%

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 ≈ 322.86, at the 94.3th 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

系統電定位為OEM/ODM與系統整合型電子製造商,核心業務為TPMS胎壓偵測系統、車用/工業電腦、能源系統與BBU電池備援模組。2025年產品營收占比:TPMS 57%、工業電腦23%、能源系統及其他20%;2024年占比則為TPMS 77%、工業電腦14%、能源系統及其他10%,顯示營收結構正由TPMS單一主軸轉向TPMS、IPC與能源系統三足並進。TPMS產品包含RF替換件、藍牙BLE TPMS、OE前裝與後裝市場產品,應用於乘用車、商用車、摩托車、重卡與車隊管理。工業電腦產品包含強固型移動裝置、特殊車輛/農耕機/工程車用電腦、AI邊緣運算裝置與無人機地面控制站。能源產品包含UPS LIB Pack、Data Center BBU、SMR通訊電源電池系統、AMR與輕型電動載具電池包,終端應用包括AI資料中心、半導體與高科技廠、通訊基地台、特殊車輛、無人機與工業自動化。2024年報揭露主要客戶以代號表示,2024年A客戶、B客戶分別占銷貨淨額34.05%、29.45%,公司受契約限制未揭露名稱。

Outlook 2025–2028

2025年公司全年營收33.94億元、年增9.1%,EPS 0.27元,獲利承壓主因包括研發費用、美國廠建置與初期營運投入。2026至2028年展望重點為BBU、強固型工業電腦與無人機三大成長引擎。BBU方面,公司已通過UL 9540A等技術門檻,3kW、5.5kW、11kW產品預計2026年第2至第3季陸續量產,德州Plano廠於2026年第1季逐步啟用全自動化BBU產線,就近供應北美AI伺服器/CSP客戶,目標2028年成為全球前三大BBU製造商之一。IPC方面,特殊車輛與大地量測新品於2025年第3季量產,鎖定高毛利、長生命週期利基專案,管理層目標每年營收年增30%。無人機方面,與Quantum Systems、Vantage Robotics等國際業者合作,布局台灣在地化生產、銷售、維修訓練與GCS地面控制站,GCS預計2026下半年放量。TPMS方面,藍牙TPMS與新車廠客戶導入預期於2026開始小量貢獻、2027至2028放大。公司2026年3月法說設定2028年營收突破新台幣100億元的中期目標,2028目標營收結構為能源系統及其他45-50%、TPMS 25-30%、工業電腦20-25%。主要風險包括:AI伺服器BBU客戶認證與量產爬坡不如預期、TPMS主要客戶庫存調整或車市需求波動、美國廠良率/成本/人力與關稅政策變動、匯率波動、研發與固定費用先行造成短期獲利壓力、主要客戶集中度高且客戶名稱未揭露。

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.
