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)
0-20 632+2.2% +0.4% 52.2% -8.8%
20-40 You are here654+10.5% +11% 68.7% -7.9%

80-100 365-9.7% -10.4% 41.6% -18.4%

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 ≈ 16.28, at the 28.7th percentile of its own history (20-40 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

正文為網通設備與無線寬頻解決方案廠,長期從事無線區域網路、寬頻接取、5G/FWA、小型基地台、Wi-Fi 家居、IoT 模組、光收發模組與 JDM/ODM 設計製造。公司官方說明其產品範圍涵蓋無線網路卡、無線網路基地台/路由器、IP STB、LTE/5G 通訊系統、雲端與物聯網應用。依 114 年度年報彙整,2025 年營收產品組合為無線網路匣道器 11,943,867.76 千元、佔 72.42%;無線網路卡 1,799,424.16 千元、佔 10.91%;無線通訊模組 120,302.45 千元、佔 0.73%;其他 2,627,993.48 千元、佔 15.94%。商業模式上,公司正由傳統品牌商代工與間接供貨,逐步轉向直接供貨電信營運商,目標是提升毛利率、縮短與終端營運商的需求回饋鏈,並用軟硬體整合與客製化解決方案提高附加價值。終端應用包含家用寬頻 CPE、PON/ONU/閘道器、Wi-Fi AP/Router/Mesh、5G FWA、企業與電信級網通設備、AI 邊緣運算 SoM/Edge AI Box、光纖接取、電信網路與 AI 資料中心光連接。

Outlook 2025–2028

2025 年是正文轉型陣痛年:114 年度合併營收約 164.93 億元,全年合併稅後淨損約 1.06 億元、每股虧損約 0.23 元;但公司指出直供電信營運商模式有助毛利率與競爭力,並將八至九成產量移往越南以降低地緣政治與關稅風險。2026 至 2028 年主要成長動能包括:一、電信直供比重提升,整合 XGS-PON、Wi-Fi 7、DOCSIS 3.1/4.0、25GS PON、毫米波 FWA、5G NR R17/RedCap 等產品,爭取北美、歐洲、亞洲與印度電信市場;二、光通訊與資料中心新事業,公司已布局 400G/800G 高速光模組,官方產品頁並宣稱光收發模組涵蓋 Broadband、Telecom、AI Data Center,速率自 1G 至 3.2T,且具 EIC-PIC、封裝、光學組裝、測試驗證到量產交付的垂直整合能力;三、AI 邊緣運算與 SoM,產品規劃包含 MoAI 路由器、Edge AI Box、1 TOP 至 275 TOP 的 System-on-Module,應用於智慧監控、工廠、零售、智慧城市、穿戴與路由器;四、軟體服務與營運商加值服務,Genix APP 與 prplWare/RDK-B 類平台可提供流量管理、資安、行為管控、裝置管理,若採分潤模式,將改善硬體代工波動。主要風險包括:中低階與消費性網通產品價格競爭、產品轉型造成舊訂單流失與營收下滑、新產品量產良率與客戶認證不確定、記憶體與關鍵零組件價格波動、美元匯率造成業外損益、關稅與地緣政治、DOCSIS 4.0 或部分寬頻技術路線需求不如預期,以及光模組進入資料中心市場面臨既有供應商競爭。2026-2028 展望屬中期推估,重點觀察指標為月營收年減幅是否收斂、毛利率能否維持改善、越南產能與湖口光模組產線稼動率、400G/800G 高階光模組量產與客戶導入、印度毫米波 FWA 標準與實際放量。

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.
