  • Largest holder 元大-桃興 has accumulated 134 lots since the start (sold 0%), still adding.

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 55+16.8% +14.4% 60% -51.1%
20-40 268-16.8% -32.2% 14.9% -35.9%
40-60 161-29.5% -34.7% 8.1% -42.2%

80-100 You are here509+29.6% +7% 62.7% -1.7%

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 ≈ 202.5, at the 95.5th 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 年展望以新一代短距無線、智慧能源/智慧城市、電子貨架標籤與海外市場擴張為主。公司 2025 年法說會列出 2025 新產品:A6133M4 5.8GHz Wireless SoC,具 512KB Flash、80KB SRAM、I2S 外部 codec 介面,主打低延遲利基應用;A3130M0 2.4GHz 低功耗 Bluetooth LE SoC,支援 BLE 5.4 電子貨架標籤;A9146M4 多頻段 Wireless SoC,支援 169/315/433/510/868/915MHz、512KB/1536KB Flash、80KB SRAM、IEEE 802.15.4g 與 Wi-SUN FAN 應用。公司表示 Wi-SUN 系列產品已取得 Wi-SUN FAN 認證,包含 FAN PHY、FAN Router、FAN Border Router。年報揭露未來三年研發方向為短距無線通訊 RF 晶片,應用涵蓋消費電子、工業自動控制與健康照護,2025 年預計投入研發費用新台幣 1.54 億元,用於新技術/新產品、研發人員、光罩、軟硬體設備、專利與認證。成長動能包含:1. Wi-SUN 作為智慧電網、智慧城市與戶外場域網路基礎設施,可帶動 Sub-1GHz 與高整合 SoC 需求;2. BLE 5.4 為電子貨架標籤規格重要演進,有利於 2.4GHz BLE SoC 切入零售電子標籤市場;3. 5.8GHz 低延遲無線音訊、麥克風與利基影音應用可改善產品組合;4. 2025Q2 非香港/中國區域占比提升至 59%,若日本、韓國、歐洲、新加坡出貨擴大,可降低單一區域需求波動。主要挑戰與風險包含:2023 至 2025 獲利轉弱,2024 EPS -0.09 元、2025Q2 累計 EPS -0.61 元,2026Q1 外部財務資料顯示仍為虧損;毛利率由 2021 年 52%、2022 年 55% 降至 2025Q2 約 43%,產品價格競爭與費用負擔仍大;晶圓代工、封測外包使成本、產能、交期與良率受供應商影響;客戶雖未被公司認定過度集中,但 2024 年最大匿名客戶約占 29.88%,若標案或終端庫存調整,短期營收波動可能明顯;Wi-SUN/BLE 5.4 等新產品需經客戶設計導入與量產驗證,實際放量時間與毛利改善仍具不確定性。

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.
