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.

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.

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 ≈ 65.13, at the 73.3th percentile of its own history (60-80 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.

Does this signal hold up across the market

Over the past 242 months, on average ~404 stocks per month met “monthly revenue YoY ≥ 20%”; their adjusted-close return over the next 60 trading days averaged 6.94% (equal-weighted), beating the market by 2.37 points on average, and outperformed the TAIEX total-return index in 64.5% of months.

Each month, equal-weighted 60-day forward adjusted return of all signal-matching stocks, then averaged across months; excess vs the TAIEX total-return index.

What does 威鋒電子 do? Company profile

半導體業；IC設計；高速傳輸、USB Type-C、USB PD控制晶片 上市（臺灣證券交易所）

Overview

威鋒電子股份有限公司成立於2008年7月7日，總部位於新北市新店區中正路529-1號7樓，英文簡稱VLI，為威盛集團旗下USB高速傳輸、USB Type-C與USB Power Delivery控制晶片設計公司。公司於2020年12月24日轉上市掛牌，證券類型為普通股。公開資訊與股市資料顯示，董事長為陳文琦，總經理兼發言人為林志峰，簽證會計師事務所為勤業眾信，股務代理為中國信託商業銀行代理部。股本約新台幣6.99億元，已發行普通股約6,986.8萬至6,994.8萬股，近期數字會因員工認股權執行略有變動。2024年合併營收為新台幣17.0031億元，歸屬母公司稅後淨利為新台幣1.57248億元，EPS為2.26元；2026年第1季合併營收約4.15億元，EPS約0.64元。主要股東方面，2024年底威盛電子股份有限公司持有38,843,000股，持股約55.67%，為母公司及最大股東。員工規模公開資料約190至194人，因不同資料年度與統計口徑不同，精確人數待最新年報確認。

Business

公司為無晶圓廠IC設計公司，主要業務為設計、研發及銷售USB相關控制晶片，涵蓋USB高速傳輸、USB Type-C、USB Power Delivery三大核心技術。產品線包括USB Hub/Host/SATA Bridge等USB系列傳輸晶片、USB Type-C介面控制晶片、DP Alt-Mode、E-Marker、Audio、Switch、Re-driver、USB PD電源控制晶片、DisplayPort轉HDMI及MST Hub等影像轉換晶片。2023年年報揭露USB相關控制晶片營收占比約99.99%，專利授權及其他收入約0.01%；2024年財報仍顯示收入主要來自USB與USB PD控制器等商品銷售，未見大幅改變。商業模式為自行研發IC與韌體、提供參考設計與技術支援，晶圓製造、封裝、測試委外，由通路商、ODM/OEM、品牌客戶與系統廠導入至擴充基座、轉接器、顯示器、PC/NB、平板、手機周邊、遊戲機、工業電腦、機器視覺、資料擷取、儲存與一般連接應用。2024年外部客戶收入地區以台灣約8.29172億元、香港及中國約6.35398億元、日本約2.23322億元為主；同年特定客戶營收占合併營收約46%，財報未揭露客戶名稱。公司產品具USB-IF認證與參與規格制定經驗，並以完整USB4、USB 3.x、USB-C與PD方案作為競爭利基。

Outlook 2025–2028

2025至2028年展望可分為復甦、規格升級與產品多元化三條主線。第一，PC/NB與周邊市場在2023至2025年經歷庫存與需求調整後，2026年公司法說與市場報導均指向營運逐季改善，第二季優於第一季、下半年優於上半年，主要來自重要客戶新產品導入、市占率提升及高階新品量產；但此屬公司與法人展望，非保證。第二，USB4、USB4 v2.0、USB-C與USB PD為長線成長動能。公司2025股東會資料指出，Windows、Mac、Linux及Apple、Intel、AMD、Qualcomm等主要平台均原生支援USB4 40Gbps，USB4產品平均訂單價值高於USB3/USB2，USB4 v2最高80Gbps規範預期未來兩三年逐步普及，公司也在開發相關解決方案。第三，產品線向DisplayPort轉換器、MST Hub與工規Hub拓展。2026年公司發表VL819i USB 5Gbps、VL822i USB 10Gbps工業級Hub控制晶片，並有VL122i、VL123i等寬溫工規USB 2.0 Hub，切入嵌入式系統、伺服器、工業電腦、智慧零售、機器視覺、資料擷取等較長生命周期市場。主要風險包括：PC/NB與消費電子需求復甦不確定；前四大客戶收入集中度高，2024年特定客戶占營收46%；上游晶圓代工與封測受AI產能排擠造成交期與成本壓力；USB/PD技術成熟後價格競爭加劇，中國與國際IC設計廠投入；美元匯率波動；先進製程與封裝投入成本上升。2027至2028的具體營收、EPS與市占率未有足夠公開可查證資料，僅能推估公司若能順利量產USB4 v2、工規與高階影像轉換產品，產品組合有機會優化，但若終端需求或客戶專案不如預期，成長可能延後。

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.
