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)
0-20 292+60.2% +31% 57.2% +33%

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 ≈ 60.16, at the 85.0th 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.

What does 沛亨 do? Company profile

半導體業;類比IC設計、電腦周邊、光通訊與網通產品 櫃買中心上櫃

Overview

沛亨半導體成立於1992年1月20日,英文名稱為Analog Integrations Corporation,股票於2004年1月28日於櫃買中心掛牌上櫃,屬營運公司普通股。公司地址為新竹縣竹北市博愛街945號,主要經營類比積體電路、混成式類比積體電路、工業用電子產品、通訊器材、消費性電子產品、電子書與電腦網路周邊產品等。2026年第一季法說資料揭露資本額約新台幣4.2億元、年營收約新台幣21億元、員工人數約400人;董事長為黃子瑋,總經理為陳銘俊。2018年加入振曜集團後,透過取得東荃、西伯、超昱及邑鋒等子公司,從原本類比IC設計公司擴展至POS/廣告機、電聲元件、光纖線材與AI資料中心相關應用。主要股東方面,官方主要股東名單顯示停止過戶日2025年4月7日時,振曜科技持有17,110,132股、持股40.74%,為最大股東;呂俊德持有4,644,532股、持股11.06%;劉宏洋持有2,593,666股、持股6.18%;劉芳君持有2,330,588股、持股5.55%。

Business

沛亨現行業務以四大事業部為主:一、電源管理IC,產品包括直流對直流轉換IC、線性穩壓IC、LED驅動IC、電池管理IC、電流功率開關IC及其他類比IC,應用涵蓋工控、消費電子、工控顯示器、人機介面顯示面板、智慧儀表與電競電腦周邊裝置。二、POS/廣告機,透過東荃與邑鋒/Pioneer POS Solution等資源,深耕北美POS、廣告機與智慧醫療應用,強調美國據點在地製造以降低關稅與供應鏈風險。三、電聲元件,透過西伯布局高階商務筆電、電競筆電、智慧裝置及電子紙/電子書相關聲學解決方案,越南新廠量產後可就近服務全球筆電供應鏈。四、光纖產品,透過超昱光電布局光纖線材、光纖通訊纜線及AI資料中心高速傳輸應用。營收結構方面,2024年資料顯示網路產品約33%、電腦及周邊設備約67%;2025年第三季法說揭露電腦周邊約75%、網通產品約25%;2026年第一季法說揭露電腦周邊約70%、網通產品約30%。2026年第一季合併營收約6.6億元、年增49%、季增10%,毛利率38%,合併營業利益約1.48億元,單季EPS 3.00元,均創同期新高。銷售模式方面,MoneyDJ資料指出2024年產品銷售區域以中國大陸37%、台灣24%、美國15%、荷蘭9%、日本5%為主,且公司產品逾八成透過代理商銷售;客戶與終端應用包含工控、消費電子、筆電、POS、廣告機、智慧醫療、AI資料中心與雲端服務供應商相關供應鏈。

Outlook 2025–2028

2025至2028年展望以AI資料中心光通訊需求、筆電/AI PC換機、北美POS與智慧醫療應用、以及集團垂直整合為核心。成長動能一:AI資料中心從100G、400G、800G往1.6T以上升級,機櫃內、叢集內與資料中心跨區互連對AOC、光纖線材與高密度光連接需求增加;公司法說與媒體報導指出光纖事業部產能供不應求,2026年產能目標由較前一年增加3倍調升至朝5倍方向推進,訂單能見度被報導已延伸至2026年底或2027年初。成長動能二:電聲元件受惠高階商務NB、電競NB與AI PC換機潮,越南新廠量產有助靠近筆電供應鏈並分散地緣風險。成長動能三:POS/廣告機因美國據點可在地製造,有助服務北美市場與智慧醫療導覽、病房監控等場景,並降低關稅衝擊。成長動能四:電源管理IC在DDR5、工控、消費電子與顯示應用維持基礎需求。主要風險包括光纖絲與關鍵原材料交期拉長、上游材料供給不足、擴產速度與良率不如預期、AI資料中心資本支出波動、客戶集中與急單轉長單的不確定性、匯率波動、北美關稅政策變化、光通訊技術路線由銅纜/AEC、AOC至CPO/矽光子之替代與規格轉換風險,以及多角化併購後整合成效。2027至2028年的具體營收、EPS與產能數字公司未完整公開,本段長期展望屬根據公司法說揭露、公開報導與產業趨勢的推估。

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.
