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)
0-20 277+46.1% +48.8% 92.1% -1.1%
20-40 233+12.5% +8% 60.5% -8.9%
40-60 193-8.4% -1.6% 49.2% -17.9%
60-80 345-2% -18.3% 27% -20.9%
80-100 You are here832+27.3% -6% 44% -9.4%

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 ≈ 78.67, at the 94.2th 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.

Currently in “Expensive (own-history top 1/3) × 60-day momentum up”: across 675 historical days, 120-day forward avg gained 20.1%, win rate 64.1%, lagged the market by 4.3%.

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 類比科 do? Company profile

半導體業/IC設計/類比IC與電源管理IC 上櫃

Overview

3438 對應台灣類比科技股份有限公司,股票簡稱類比科,為櫃買中心上櫃普通股,非 ETF、ETN、權證或特別股。公司成立於 1999/03/25,股票於 2006/07/19 上櫃,總部位於新竹縣竹北市台元科技園區台元二街1號7樓之1,台北內湖亦有據點。董事長為吳錦川,總經理兼發言人為林登財。依 Yahoo 股市與櫃買中心資料,實收資本額約新台幣 471,658,150 元,已發行普通股 47,165,815 股,主要經營業務為積體電路之設計;公開徵才資料顯示員工數約 130 人。主要股東方面,致新科技及其子公司致強投資合計持股約 43.53% 至 43.54%,致新科技取得董事會過半席次,為單一最大股東及最終母公司;114 年股東會董事候選名單亦顯示致新科技持有 20,535,212 股並提名多席董事。公司曾於 2016 年以股份轉換取得遠翔科技 100% 股權,2018 年與遠翔科技合併,由類比科為存續公司。

Business

類比科為專業類比 IC 設計公司,採 IC 設計/Fabless 模式,主要自行研發與銷售電源管理 IC、磁場感測及馬達驅動 IC、微控制器 MCU IC 等,晶圓製造與封裝測試委外。2024 年產品營收比重約為電源管理 IC 73%、磁場感測及馬達驅動 IC 24%、微控制器 IC 3%;2024 年銷售區域約台灣 25%、外銷 75%。電源管理 IC 包含 DC-DC 控制器與轉換器、LED 驅動 IC、面板電源控制 IC,應用於中小尺寸 TFT/OLED/AMOLED 顯示器、筆電面板、LCD 顯示器/電視背光、網通設備、機上盒、智慧穿戴、行動電源與照明。磁場感測及馬達驅動 IC 包含 Hall IC、無刷直流馬達控制與驅動 IC、整合 Hall 感測與馬達驅動的 All-in-One IC,主要用於筆電、桌機、伺服器與家電散熱風扇、汽車空調循環系統與影音設備散熱。MCU 產品以 8 位元微控制器為核心,應用於小型消費電子、PC 週邊與 3C 週邊,例如遙控器、玩具、電子菸、加濕器、無線耳機充電、手機充電線與 USB 充電標準控制。主要客戶未逐名揭露,公開資料描述為國內面板廠、中國大陸面板廠、LCM 客戶、NB 品牌廠及相關通路。2025 年全年營收約 10.11 億元;2026 年 1 至 5 月累計營收約 3.62 億元,年減約 19.66%,5 月單月營收約 7,813.3 萬元,月減 8.69%、年減 15.47%。

Outlook 2025–2028

2025 至 2028 年展望需分成已揭露與推估兩部分。已揭露部分:公司 2025 年上半年營收約 5.42 億元、年增約 14%,營業利益約 2,700 萬元、年增約 22.6%,但毛利率由去年同期約 40% 降至約 33%,稅後淨利受 2025Q2 匯兌損失影響降至約 671 萬元;公司 2025 年法說會未提供未來季度或年度明確財測。公司年度營業計畫指出,將持續取得面板廠開發資格,投入高亮度穿戴式與消費型產品電源管理 IC、馬達驅動 IC、整合型 MCU IC,深化既有客戶與代理商合作,並與晶圓代工及封裝測試廠維持緊密關係。研發方向包含中小尺寸電競面板電源管理 IC、AMOLED 高亮度高壓穿戴式產品電源管理 IC、新型全正壓高驅動力穿戴式面板電源管理 IC、中大尺寸面板電源管理 IC、LED 照明電源控制 IC、三相直流無刷馬達磁感測/控制/驅動 IC、閉迴路轉速控制馬達驅動 IC、通用 MCU、多埠 USB-PD 控制器加降壓電源控制 IC、CMOS 磁場感測 IC。推估部分:2025 至 2028 年成長動能主要來自智慧穿戴 OLED/AMOLED 滲透、顯示器與電競面板規格升級、AI 伺服器與高階 PC 散熱風扇對馬達驅動與感測 IC 的需求、網通與消費性電源應用復甦,以及 MCU 與電源管理整合帶來的客戶黏著度提升。主要風險包括面板與消費電子景氣循環、客戶庫存調整、產品週期性降價、產品組合變動造成毛利率波動、匯率波動、晶圓代工及封測成本與產能供給、國內外類比 IC 廠價格競爭,以及未揭露長期財測造成能見度有限。2026 年前 5 月營收年減顯示短期需求仍有壓力,故 2026 至 2028 年展望應以產品導入與終端需求復甦程度作為觀察重點,而非假設線性高成長。

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.
