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.

Historical evidence

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)
0-20 0Insufficient data
20-40 0Insufficient data
40-60 0Insufficient data
60-80 0Insufficient data
80-100 You are here0Insufficient data

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 ≈ 190.68, at the 98.6th 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.

What does 天宇 do? Company profile

綠能環保 上櫃

Overview

8171 對應天宇工業股份有限公司,為櫃買中心上櫃普通股,非 ETF、ETN、權證或特別股。公司成立於 1983/10/01,統一編號 38426929,2010/09/08 公開發行、2010/10/08 興櫃、2011/12/19 上櫃掛牌。總部與登記地址為新北市新店區民權路130巷8號5樓;官網另列總公司暨研發中心、新竹竹北廠、桃園大園據點及中國昆山據點。董事長為吳祖璋,總經理與發言人為劉奇威。公開資料列示實收資本額約新台幣 11.2853 億元,普通股已發行 112,853,326 股,無特別股。員工規模未在交易所基本資料中直接揭露;104 人力銀行頁面列員工數約 100 至 120 人,MoneyDJ 財務比率頁曾列合併員工人數約 183 人,故員工規模以 100 至 183 人區間看待。主要股東依公司官網十大股東頁,列有盧米埃國際股份有限公司相關持有人、天振投資有限公司、吳祖璋等;惟官網頁面以股東名稱加代表人方式列示,未能完全判斷最終受益人與重複代表關係。重要子公司包含夸克能源股份有限公司,主要經營能源技術服務。

Business

天宇早期從線材、視聽電機組裝、行動電話電池組、3C 電池與行動電源 ODM/OEM 起家,曾承接 HTC、TomTom、SoftBank、小米等相關 OEM/ODM 或合作案;近年轉型為鋰電池模組、儲能系統、能源整合與節能工程公司。主要產品與服務包括:一、儲能貨櫃與大型儲能系統,產品含 10 呎 1MWh、20 呎 3MWh、20 呎 5MWh 液冷儲能貨櫃,整合電池模組、BMS、EMS、PCS 與消防防護,應用於再生能源併網、工業備援、虛擬電廠、需量反應、電網調節與削峰填谷。二、工商儲能與家用儲能,搭配太陽能逆變器、自發自用與停電備援需求。三、特殊電池模組,包括 AGV 電池組、BBU 備援電源、UPS 電池組、動力電池與其他客製化電池模組。四、再生能源案場與能源技術服務,子公司夸克能源涵蓋再生能源開發、工程、綠電轉供與企業永續能源服務。五、節能與機電工程,業務包含能源管理系統、智慧控制、醫療與公部門節能案、電力、弱電、消防、空調、給排水、中央監控等整合工程。營收結構方面,第三方整理 2025/2026 前後資料顯示公司營收已由單純電池模組轉向儲能、工程收入與能源服務;StockFeel 頁面列示營收以儲能系統約 78.3%、其他營運事業部約 15.2%、電池模組約 6.5% 為主,但公司年報型資料又顯示 2025 年受美系 Powin 客戶破產與停止出貨影響,儲能櫃與電池模組 OEM/ODM 大幅衰退,工程收入、再生能源、節能與機電工程比重上升。因此,現階段商業模式可概括為:由電池模組代工製造,逐步轉向自有品牌儲能設備、案場系統整合、能源服務、節能工程與再生能源資產經營。

Outlook 2025–2028

2025 至 2028 年展望分為轉型機會與修復風險兩面。成長動能方面,台灣企業用電大戶、再生能源併網、需量反應、削峰填谷、資料中心與工業備援需求,使表後儲能與能源管理市場具中長期成長性;天宇官網與年報型資料均把未來主軸定位為「創能、儲能、節能、智慧能源」,並推動工商儲能、家用儲能、液冷儲能櫃、能源管理軟體、ESCO 節能服務、機電工程與綠電轉供。公司提出發展方向包括持續收購或開發已併網太陽能案場、擴大自有發電量、切入日本儲能市場、推展儲能櫃銷售、布局亞太與澳洲市場、發展醫院節能市場、無人機、電動二輪車及 BBU 備援電源。公司官網與公開資料亦顯示已推出企業儲能「零元試用六個月」方案,試圖以租賃、購買或分潤模式降低客戶初期導入門檻。產能與技術方面,官網揭露大園廠量產啟動與年產能 1.5GWh,並強調竹北與大園雙基地、儲能安全、消防、散熱、備援與國際安全認證。主要挑戰方面,2025 年美系儲能客戶 Powin 依美國破產法聲請破產,天宇對其應收帳款約 919.4 萬美元,雖有預收款與提列備抵呆帳,但仍暴露單一大客戶、海外客戶信用、應收帳款回收與營收波動風險;公司也因停止對 Powin 出貨與產能利用不足,面臨毛利率、固定成本吸收與轉型期間虧損壓力。2026 至 2028 年若自有品牌儲能、節能工程、機電工程、太陽能案場收購與海外儲能市場能按計畫放量,營收結構可望較 2025 年低谷改善;但若案場收購、工程承攬、海外拓展或資金調度不順,或電芯價格、匯率、利率、補助政策、台電併網規範及消防安全法規變動,均可能壓抑獲利修復。

Supply Chain

Upstream
  • 鋰電芯與電池材料供應商 天宇儲能貨櫃與電池模組需採購鋰電芯、電池材料與相關電子零組件;公開資料未確認特定供應商名稱,故不填台股代號。

Downstream
  • Powin, LLC 美國儲能系統公司,非台股;天宇曾為其儲能電池櫃/相關產品供應商或債權人。Powin 於 2025 年聲請美國破產法第 11 章,天宇已停止出貨並提列相關應收帳款備抵。

  • 工業用電大戶、工廠、工地、資料中心、港口、太陽能電場、醫療與公部門客戶 天宇儲能、節能與機電工程的主要應用場域;多數客戶未由公司逐一揭露,屬客戶類型而非單一掛牌公司。
  • HTC、TomTom、SoftBank、小米 歷史合作或 OEM/ODM 客戶/合作對象;HTC 為台股 2498,惟屬早期手機電池或行動電源階段客戶,非目前儲能主軸客戶,因此不填為現行台股下游客戶。

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.
