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.

PE percentile bandSample days240-day avg returnMedianWin rateAvg excess (vs index)

80-100 You are here821+64.3% +5.8% 58.3% +39%

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 ≈ 24.94, at the 94.0th 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.

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 宜鼎 do? Company profile

電腦及週邊設備業；工業級嵌入式儲存、工業用記憶體模組、邊緣AI解決方案 櫃買中心上櫃

Overview

5289 對應宜鼎國際股份有限公司，英文名稱 Innodisk Corporation，為櫃買中心上櫃普通股，非ETF、ETN或權證。公司成立於2005年3月16日，2012年10月5日興櫃，2013年11月27日上櫃，總部位於新北市汐止區大同路一段237號5樓，並於宜蘭設有研發製造中心。董事長及總經理為簡川勝。依櫃買中心與公開資料，公司主要經營工業用嵌入式儲存裝置、工業用動態隨機記憶體模組。資本額約新台幣9.6至9.63億元，2026年法說會揭露2025年營業額新台幣143億元、EPS 21.72元、專利數203件、客戶數逾4,000家、營業地區25國、全球員工1,164人。主要股東依2025年年報列示，包含睿鼎投資股份有限公司約7.60%、國泰人壽保險股份有限公司約5.25%、李鐘亮及其配偶合計持股、皮克朱投資有限公司、朱慶忠、簡川勝，以及外資保管專戶等。

Business

宜鼎核心商業模式為工業級利基型記憶體與儲存模組設計、製造、韌體開發、客製化驗證、長期供貨與技術支援，近年延伸至邊緣AI系統與軟硬整合方案。2024年產品營收結構為工業用嵌入式儲存裝置新台幣45.74億元、占51.31%；工業用動態隨機記憶體模組新台幣34.62億元、占38.83%；AI邊緣運算解決方案新台幣6.41億元、占7.19%；其他新台幣2.38億元、占2.67%。2025年法說會揭露產品營收占比約為DRAM 37%、Flash 55%、AI Solutions 6%、Others 2%。主要產品包含2.5吋SSD、Slim SATA、M.2、U.2、CFast、mSATA、SATADOM、nanoSSD、CF、SD與MicroSD、USB、CFexpress、EDSFF等工業儲存；嵌入式、伺服器、寬溫、極寬溫、強固客製與AI高效記憶體模組；AI邊緣運算平台、AI SDK、邊緣裝置雲端管理平台、AI加速卡、GPU與AOI AI瑕疵檢測方案；以及嵌入式相機、I/O、RAID、通訊、車用通訊、空氣感測、OOB管理與GNSS模組。終端應用橫跨工業電腦、自動化設備、智慧交通、POS、安全監控、醫療、數位看板、伺服器、航太、智慧製造、邊緣運算、智慧城市、智慧車載、智慧零售、能源與基礎建設。公司113年度無單一客戶占銷貨總額10%以上，顯示客戶組合分散；全球客戶數逾4,000家。公司宣稱自2018年起連續七年為工業級SSD全球市占第一，並自2019年起連續六年列入TrendForce全球前十大DRAM模組廠，是其中專注工控記憶體模組的供應商。

Outlook 2025–2028

2025至2028年展望核心在邊緣AI、資料中心儲存、AI伺服器周邊、工業自動化、機器人與企業私有AI導入。2025年公司營收新台幣142.61億元、年增60.0%，營業利益年增102.8%，EPS 21.72元，反映AI基礎建設與記憶體/儲存需求回溫。2026年法說會提出Edge AI五層架構，涵蓋算力、記憶體、儲存、感測傳輸與軟體，產品方向包含APEX邊緣AI系統、AI代理人邊緣工作站、多加速卡推論系統、E3.L PCIe Gen5資料中心SSD、LPDDR5X LPCAMM2、CXL記憶體、DDR5 7200MT/s、MRDIMM、CAMM2/LPCAMM2、MIPI over Type-C與GMSL2相機模組等。產能方面，宜蘭研發製造中心2026產能規劃約1,080K、最大產能1,440K，搭配二廠空間強化Edge AI系統、嵌入式周邊與相機模組量產能力。外部成長動能包括AI與5G推動資料吞吐量提升、邊緣端低延遲需求、工業電腦與AIoT升級、企業私有LLM與數位孿生、機器人應用，以及上游DRAM/NAND產能向高階AI與伺服器產品傾斜造成的工控與企業級模組供需緊俏。公司短期計畫為擴大AI解決方案完整性、累積全球落地案例、深化產業夥伴與子公司合作、擴充海外業務與技術支援；長期計畫為深化全球生態系、與國際科技大廠技術接軌並建立全球AI解決方案品牌定位。主要風險為DRAM與NAND價格循環、上游原廠供貨與配給、庫存成本、外銷占比高導致匯率波動、AI專案高度客製化且導入期較長、邊緣AI商業化速度不確定、競爭者增加、資安與供應鏈安全要求提高，以及終端工控與企業IT資本支出受景氣與關稅影響。2028之後的具體財測未見公司正式發布，相關成長推論主要來自公司法說、年報與產業趨勢。

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.
