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.

80-100 You are here1103+18.1% +9.2% 64.7% -3.3%

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 ≈ 305.56, at the 97.0th 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.

Outlook 2025–2028

2025 至 2028 年展望重點在 AI 資料中心高速交換器、Wi-Fi 7、印度 LBR 專網、5G/O-RAN、DOCSIS 4.0/寬頻升級與全球製造布局。2025 年公司持續推動轉型,深化 Data Center 與 AI Data Center 產品技術,推出 1.6T 水冷式交換器,搭載 Broadcom Tomahawk 6 晶片,訴求 64 埠 1.6T、102.4 Tbps 交換容量、ORv3 架構與直接水冷技術,目標應用於 AI/雲端資料中心與 HPC。2026 年公司管理層與媒體報導均指出下半年為成長重點,主要動能包括 400G 交換器放大出貨、800G 送樣並力拚年底放量、1.6T 水冷交換器第二季送樣並力拚年底量產、印度 LBR 解決方案落地、美國加州爾灣製造基地設立以支援在地製造與敏感產品需求,以及 Wi-Fi 7 產品需求成長。2027 年若 800G/1.6T 交換器導入電信與超大規模雲端客戶順利,商用/資料中心交換器比重有機會提升;經濟日報報導提到公司預估 2027 年營運商用交換器占整體交換器比重可望達二成。2028 年較屬中長期推估,AI 資料中心頻寬升級、Wi-Fi 7 裝置滲透、5G 專網、低軌衛星地面設備、智慧家庭與車載通訊仍是可追蹤方向,但明泰尚未公開完整 2028 財務目標。主要風險包含高速交換器驗證期長、AI 資料中心客戶認證與量產時程不確定、Broadcom 等關鍵晶片與記憶體供應/價格波動、水冷與高層數 PCB 良率挑戰、關稅與美中科技管制、美元匯率、網通客戶庫存循環、ODM 價格競爭、印度與美國新市場執行風險,以及公司 2025 年仍虧損、轉型成效需由實際訂單與毛利率驗證。

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.
