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)
0-20 232+140.6% +57% 94.4% +106.6%
20-40 701+82.3% +41.4% 84.7% +65.1%
40-60 549+27.2% +14.1% 64.8% +10.3%

80-100 You are here1002-14.1% -17.8% 12.8% -22.7%

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 ≈ 30.63, at the 86.4th 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.

Days = trading days in this bucket; returns use adjusted prices, ex-costs. 60-day momentum: direction of this stock's price over the past 60 trading days.

What does 亞信 do? Company profile

半導體業;網路通訊 IC、工業/嵌入式乙太網路與 I/O 橋接控制 IC 設計 上櫃(櫃買中心)

Overview

亞信電子成立於1995年5月12日,總部位於新竹科學園區新竹市新安路8號4樓,2009年11月24日於櫃買中心掛牌上櫃。董事長為王春旗,總經理為范振鋒,發言人為王春旗。公開股市資料顯示資本額約新台幣6.31億至6.33億元,已發行普通股約6,310.70萬至6,330.70萬股;不同資料時間口徑略有差異。公司網站與104資料均描述其為專業網路相關 IC 晶片設計廠商;104揭露員工人數為「暫不提供」,因此員工規模未能確認。主要股東方面,2020年聯發科旗下絡達擬以私募方式取得約2成股權,市場資料將亞信歸為聯發科集團或聯發科持股關聯公司;Yahoo股市資料顯示董監持股比例約22.37%,所屬集團為聯發科。

Business

亞信為無晶圓廠 IC 設計公司,產品自主研發後委託晶圓代工與封裝測試廠生產,再銷售給網通、PC週邊、工業電腦、工業自動化與嵌入式系統客戶。主要產品包括EtherCAT與工業乙太網路晶片、TSN解決方案、超高速USB乙太網路晶片、Non-PCI/SPI嵌入式乙太網路晶片、串並口I/O橋接器、PCIe/USB轉串並口I/O橋接晶片、RS-232/RS-485收發器、USB KVM單晶片、網路微控制器與Wi-Fi/乙太網路單晶片等。MoneyDJ資料顯示2024年產品營收比重為網路通訊IC與輸出入控制晶片合計100%,銷售區域約大陸41%、台灣32%、其他27%。終端應用包含工業自動化智慧工廠、工業物聯網IIoT、電腦周邊、智慧居家與辦公室網路產品、工業電腦、I/O串列埠、USB KVM、多媒體網路、POS、寬頻分享器、網路攝影機、遊戲機與家用閘道器等。公司官網新聞提及其嵌入式/USB乙太網路晶片曾獲Apple USB乙太網路卡、Nintendo Wii/Switch USB乙太網路卡、ASUS/DELL/MSI/SONY筆記型電腦等認證或採用;MoneyDJ亦報導蘋果及任天堂Switch網路卡採用亞信乙太網路控制IC。

Outlook 2025–2028

2025至2028年的主要成長動能在工業乙太網路、EtherCAT、TSN、IO-Link、USB 2.5G/USB 3.2乙太網路與工業物聯網應用。公司官網重要里程碑顯示2025年推出AX58101 EtherCAT子設備控制器與AX88279A USB 3.2轉2.5G乙太網路晶片,2024年推出AX99100A PCIe轉多I/O控制器與IO-Link設備軟體協議棧解決方案;這些產品有利於補足智慧製造中從感測器、I/O到乙太網路的連接鏈。中期機會包括工業自動化升級、AI導入工業物聯網、智慧工廠、機器人/馬達控制、TSN確定性網路、邊緣設備高速有線連接,以及聯發科/達發生態系可能帶來的通訊與網通客戶協同。MoneyDJ報導亞信與安勤合作推出TSN開發平台與EtherCAT轉IO-Link閘道器over TSN整體解決方案,並指出工業市場導入AI後乙太網路產品出貨動能可望擴大。主要風險包括公司規模小、產品集中於網路通訊IC與I/O控制晶片、客戶design-in週期長且訂單波動大、成熟製程晶圓代工與封測成本及產能風險、USB/乙太網路控制IC面臨國內外大廠價格與規格競爭、終端PC與消費性電子景氣循環、工控需求復甦不如預期、匯率與中國大陸銷售比重較高所帶來的地緣與需求風險。2026至2028具體財務預測未見公司正式公開指引,因此不臆測營收或EPS數字。

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.
