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 ≈ 30.03, at the 45.5th percentile of its own history (40-60 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 AES-KY do? Company profile

電子零組件業；鋰電池模組、備援電池系統與輕量型電動載具電池模組 臺灣證券交易所上市

Overview

6781 對應證券為 AES-KY，為在臺灣證券交易所第一上市之外國發行人普通股，非 ETF、ETN、權證或特別股。公司註冊地為英屬開曼群島，成立日期為 2020/01/09，臺灣證交所上市日期為 2021/03/22。公司總部與主要聯絡地址為新竹縣湖口鄉八德路二段656號；官方揭露主要生產基地包括中國大陸常熟、臺灣新竹，並於 2022 年設立越南子公司 Trend Power Technology (Vietnam) Company Limited。董事長為宋福祥，總經理為宋維哲；官方基本資料列示實收資本額約新台幣 8.5 億元，公司簡介列資本總額新台幣 854,180 仟元。主要股東依公司官網 113/3/30 基準日：永豐商業銀行受託保管中普科技控股（薩摩亞）有限公司投資專戶持股 54.77%、富邦人壽 5.16%、全富（英屬維京群島）有限公司投資專戶 5.01%、國泰人壽 4.91%、朗天國際有限公司投資專戶 4.33%。員工規模官方年報網頁未在可擷取段落清楚列示；第三方財務資料曾列員工人數約 990 人，因非公司官網直接揭露，僅作參考。

Business

AES-KY 核心業務為專業鋰電池模組研發、製造與銷售，主要產品包含輕量型電動載具電池模組、中大型工業儲能系統電池模組與備援電池系統。官方產品頁揭露，輕量型電動載具應用包含電動自行車、電動摩托車、電動平衡車等；中大型工業儲能包含儲能系統、家用儲能、大型儲能站、備援電池系統與工業用電池系統。商業模式偏客製化共同開發與一站式解決方案，涵蓋電芯選擇、BMS 電池管理系統、機構設計、射出成形、金屬沖壓、產品驗證與法規認證；公司亦強調內部實驗室可執行性能、安全、老化與全球法規測試。依 114 年報摘要，2025 年營收為新台幣 16,000,812 仟元，年增 59.4%；產品組合中鋰電池模組金額 15,946,702 仟元、占 99.7%，其他 54,110 仟元、占 0.3%。2024 年營收為新台幣 10,036,842 仟元，年增約 0.05%，主要受輕量型電動載具品牌庫存去化與高通膨購買力下降影響，但中大型工業備援系統、資料中心與工控型鋰電池模組成為後續成長主軸。公開研究資料指出 LEV 業務模式包含供貨給 Shimano、Yamaha Motor 等電控系統廠，以及與巨大、美利達等終端自行車品牌共同設計；BBU/資料中心客戶市場則常被法人與媒體連結至大型雲端服務商與 AI 伺服器供應鏈，但個別終端客戶多非公司正式逐名公告。

Outlook 2025–2028

2025 年已見高成長：114 年報摘要顯示營收達新台幣 160.01 億元、年增 59.4%，稅後純益新台幣 32.63 億元、年增 50.5%，EPS 38.20 元；成長主因為中大型工業備援系統等工控型鋰電池模組成長。2025 年以後至 2028 年的主要動能包括：一、AI 伺服器與資料中心擴建推動 BBU 備援電池需求，尤其高功率密度機櫃、邊緣運算、儲存與 5G/電信設備需要較傳統鉛酸 UPS 更高能量密度、壽命與可管理性的鋰電池模組；二、公司已深耕工控型與資料中心備援模組多年，法人報導稱其將持續擴增新客戶、新產品與市占率，2025 下半年亦有 5G 電信與工業儲能客戶貢獻的預期；三、輕量型電動載具長期仍受碳中和、城市短途移動、電動自行車與電動摩托車滲透率提升支撐，但 2023-2025 年產業庫存去化與歐美消費力疲弱使復甦節奏不確定；四、公司研發方向包含通訊電池、高階腳踏車電子系統電源模組、磷酸鋰鐵電池平衡策略、可維修電池模組與延緩電池老化方案。2026-2028 年潛在風險包括：AI 伺服器 BBU 是否由選配走向更高滲透率存在不確定性；CSP 客戶認證與拉貨節奏集中，可能造成營收波動；鋰電池安全法規與產品責任風險高；上游電芯、鋰、鎳、鈷、磷酸鐵鋰等材料價格波動會影響毛利；中國、臺灣、越南產能配置可能受美中科技戰、關稅與地緣政治影響；LEV 客戶庫存循環與歐美景氣仍可能壓抑出貨。

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.
