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.

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 ≈ 8.31, at the 14.9th percentile of its own history (0-20 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.

Business

威剛為記憶體模組與儲存產品品牌廠，核心商業模式是向上游 DRAM IC、NAND Flash/FLASH IC 原廠或代理商採購顆粒，進行模組設計、韌體與相容性驗證、製造測試、品牌行銷與全球通路銷售；景氣循環中庫存成本、採購時點與產品 ASP 是獲利波動關鍵。主要產品包括 DRAM 記憶體模組、DDR5/XPG 電競記憶體、工作站與伺服器用 RDIMM/ECC DIMM、工控記憶體、消費性快閃記憶卡、USB 隨身碟、外接式儲存裝置、SSD、企業級與工業級 SSD、行動裝置週邊與 XPG 電競產品。2024 年報說明 DRAM 模組應用於桌機、筆電、工作站、伺服器、POS、電競 PC/筆電、創作者電腦與印表機；SSD 應用於平板、桌機、筆電、遊戲機、企業級伺服器、工業電腦與雲端伺服器；工控產品涵蓋網通、博弈、工業自動化、運輸、醫療、監控、能源、航太等場域。營收結構方面，2024 年全年營收 402 億元，其中 SSD 營收逾 121 億元；2024 年 12 月單月 DRAM 模組占 54.33%、SSD 占 32.36%、記憶卡/隨身碟與其他占 13.31%；2026 年 5 月公司公告 DRAM 仍為第一大產品線，占 52.9%，SSD 單月營收 47.3 億元、占 36.5%，記憶卡、隨身碟與其他占 10.6%。下游客戶年報未具名，僅揭露主要銷售對象包括記憶體通路商、記憶體模組製造商、主機板製造商、準系統製造商、顯示卡製造商及其他 3C 產品製造與通路商；2024 年銷售前幾大客戶以匿名代號揭露，單一客戶集中度不高，2024 年僅一名客戶銷售比率超過 5%。除記憶體本業外，公司亦有多角化布局，包括台灣運彩、文創商場與影音中心、綠能減碳與電動三輪車等，但投資判斷上仍以記憶體與儲存產品週期為主要獲利來源。

Outlook 2025–2028

2025 至 2028 展望核心在 AI 伺服器、AI PC、AI 手機與邊緣運算帶動 DRAM 與 NAND Flash 容量需求上升。2024 年報引用研調資料指出，2025 年三大 DRAM 製造商仍將產能與投資聚焦 HBM 與 DDR5，全球 DRAM 產值可望年增，AI PC 出貨滲透率提升將推動終端裝置記憶體容量增加；NAND Flash 原廠資本支出與投片較保守，但企業級 SSD 需求受 AI 與資料中心應用拉動，預期優於其他 NAND 應用。公司 2025 經營方針包括推出全系列 DDR5 記憶體模組、PCIe Gen5 SSD、XPG 電競產品，拓展 RDIMM、ECC DIMM、工業級 DDR5、CU-DIMM/CSO-DIMM、高階 SSD 與 A+ Analyzer 客製化分析工具，並深入日本、印度、東南亞、中南美洲等市場。2026 年 5 月公告顯示記憶體價格續揚，威剛連續三個月刷新單月營收紀錄，前五個月營收 496.1 億元、已達 2025 年全年營收約 93%；董事長陳立白表示在全球記憶體供給有限下，DRAM 與 NAND Flash 合約價可望同步上揚，公司將提高庫存水位，第三季庫存規模目標逾 500 億元，並深化 AI 伺服器、企業級儲存與 TRUSTA 企業級儲存品牌。2026 至 2028 的成長動能可概括為：一、AI/HPC 帶動 DDR5、RDIMM/ECC DIMM、企業級 SSD 與高容量 SSD 需求；二、原廠資本支出偏向 HBM 與高階產品，使傳統 DRAM/DDR4/DDR5 與 NAND 供給緊縮時，具備庫存與供應鏈關係的模組廠可受惠 ASP 與價差；三、工控、醫療、交通、監控、邊緣 AI 等市場提高高可靠度記憶體與儲存需求；四、全球在地化生產與多地通路可降低關稅與地緣政治衝擊。主要風險包括：記憶體高度循環，若 2027 至 2028 原廠產能開出或 AI 需求不如預期，價格與庫存評價可能反轉；高庫存策略在漲價循環中放大獲利，但在跌價循環中也放大跌價損失與營運資金壓力；上游供應集中於三星、SK hynix、美光、鎧俠等國際大廠，模組廠議價力與配貨能力有限；NAND Flash 供應家數較多且中國低價競爭可能壓抑價格；關稅、匯率、地緣政治、客戶延後拉貨、通路資金壓力與高本益比預期修正均可能影響股價與獲利能見度。2027 至 2028 具體財務數字公司未提供公開財測，本段屬依公司公開展望、法說內容與產業趨勢的分析推估。

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.
