Branch inventory reconstruction

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.

Current PE ≈ 39.78, at the 61.6th percentile of its own history (60-80 band).

Outlook 2025–2028

2025至2028年展望重點在產品升級、產能轉移與客戶結構改善。2025年公司表示將隨新產品導入與越南新廠投產,逐步恢復成長動能;2025年營收約41.90億元,較2024年約35.95億元成長,且通訊產品占比提高至95.53%。成長動能包括Wi-Fi 7 AP/路由器、PON與XGS-PON光纖接取設備、管理型交換器、雲端/地端控制器、SMB全方位企業網路解決方案、SD-WAN、10G交換器、AI強化IP Camera、智慧家庭與邊緣AI應用、衛星通信閘道器與低軌衛星相關產品。公司北越新廠於2024年第四季竣工、2025年投入生產,市場報導指出2025年第二季已投產,且產品線全面移轉至越南,產能為既有產能四倍,有助降低地緣政治與關稅風險並承接新產品與新客戶。2026年展望方面,法說與媒體報導指出公司將全力推進Wi-Fi 7、光纖PON與交換器新產品,客戶新開案多以Wi-Fi 7為主且往中高階產品移動,預估Wi-Fi 7出貨占比提高,法人預期若新產品順利出貨,2026年營收有機會雙位數成長、本業力拚轉盈。2027至2028年可期待Wi-Fi 7滲透率提升、2.5G/5G/10G乙太網路升級、企業雲管網路與SD-WAN普及、低軌衛星與韌性通訊需求帶來新案,但此部分屬產業趨勢推估而非公司正式財測。主要風險包括網通產品價格競爭激烈、客戶集中度偏高、客戶需求波動、產品轉換期毛利壓力、匯率、關稅與地緣政治、越南廠良率與移轉執行風險、Wi-Fi 7普及速度低於預期,以及中國品牌與台灣同業競爭。

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.
