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 ≈ 24.92, at the 67.4th 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.

What does 品安 do? Company profile

半導體；記憶體模組、快閃記憶體與電子製造服務（EMS） 上櫃

Overview

品安科技成立於1994年2月1日，總部位於台北市內湖區成功路五段460號9樓，營運中心與二廠位於基隆市七堵區。公司於2003年登錄興櫃，2004年2月27日掛牌上櫃，證券代號8088。董事長與總經理皆為謝吳沛，發言人為吳惠珠。公開資料顯示實收資本額為新台幣609,217,499元，已發行普通股60,921,749股。主要經營業務為記憶體模組、積體電路、快閃記憶體與代工。股務代理為富邦綜合證券。董監持股比例約11.04%；截至可查資料，董事長謝吳沛持股約3,936張、董事吳惠珠約2,791張。公司官網揭露其製造服務中心位於台灣六堵科技工業園區，具12條SMT線、DIP線、自動組裝與測試設備，並建構智慧型製造管理系統。公司已取得或揭露ISO9001、ISO14001、ISO45001、ANSI/ESD S20.20、RBA銀標、IATF 16949：2016、ISO27001、ISO14064-1等品質、車用、資安與碳盤查相關認證。員工規模與完整前十大股東名單未能在本次可查公開網頁中確認。

Business

品安的業務可分為自有產品與代工產品兩大類。自有產品包括工業用DRAM記憶體模組（DDR5 UDIMM、DDR5 SODIMM、DDR5 CUDIMM、DDR5 RGB UDIMM、DDR4 UDIMM、DDR4 SODIMM與ECC版本）、工業用記憶體卡（SD、microSD、SDHC、SDXC、CF、CFast）、工業用嵌入式儲存（2.5吋SSD、M.2、mSATA、Half-Slim SSD）及工業電腦擴充卡（Mini PCI-e、M.2等）。EMS代工服務涵蓋硬體設計、外觀開模、DIP、SMT、IC測試與分類、雷射焊接、點焊、雷射雕刻、組裝、測試、包裝、全球運籌、RMA與EOL管理；產品應用已從記憶體模組擴及機械鍵盤、顯示卡、醫美電子產品、工控記憶體模組、觸控控制板、讀卡機、IP Phone、FPGA開發板、控制板、智慧燈、智慧電表、VGA Card、Thunderbolt 3方案與電源控制板等。富果法說摘要指出，2025年公司營收結構已轉向EMS代工為主，代工產品約佔69%，自有產品約佔31%；此比重為第三方依公司法說會整理，非本次直接自年報表格抽取。商業模式上，品安以客製化設計、OEM、ODM與EMS承接客戶專案，提供EVT、DVT、PVT到量產導入服務，並透過供應商策略聯盟、第二來源承認、長交期備料與客製化生產管理降低交期與庫存風險。主要客戶名稱未在可查公開資料中明確揭露；依法說摘要，終端客戶與應用涵蓋大數據、工業製造、醫療、教育、交通、多媒體、AI、物聯網、車用電子、消費性電子，區域包含德國、日本及亞洲其他地區。

Outlook 2025–2028

2025至2028年的主要成長動能來自三條線：第一，AI伺服器與資料中心推升DRAM、DDR5、NAND與SSD需求，TrendForce在2026年3月指出AI伺服器需求使2Q26傳統DRAM合約價季增58%至63%、NAND Flash合約價季增70%至75%，供應商持續把產能轉向伺服器相關應用，整體供應偏緊；2026年1月TrendForce亦預估記憶體市場規模2026年達5,516億美元、2027年達8,427億美元。這對品安自有記憶體模組、SSD與工控儲存產品的報價與毛利有利，但也會提高採購成本與備貨資金需求。第二，品安近年將EMS代工比重拉高，若能持續取得AI、工控、醫療、教育、交通與多媒體相關客戶訂單，營運波動可望較過去單純記憶體模組通路模式分散；公司法說摘要指出，管理層對2026年維持謹慎正向，認為DRAM DDR4/DDR5缺貨可能延續至2026甚至2027，且已預先儲備庫存。第三，製程與認證升級，包括12條SMT線、智慧製造管理系統、IATF 16949車用品質系統、ISO27001資安與ISO14064-1碳盤查，將有助爭取國際大廠、高規格工控與車用電子供應鏈。主要風險包括：記憶體景氣循環反轉導致報價與庫存跌價損失；DRAM/NAND上游集中於三星、SK海力士、美光等國際大廠，議價權與供貨穩定度不易掌握；EMS代工若客戶集中或產品良率、交期不佳，可能侵蝕毛利；AI需求若低於市場預期或雲端資本支出降溫，2027至2028可能出現供需反轉；另有匯率、地緣政治、關稅與客戶要求ESG/資安稽核成本上升等挑戰。

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.
