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 ≈ 12.84, at the 33.9th percentile of its own history (20-40 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.

Overview

台灣精星科技股份有限公司成立於1990年12月15日，總部位於新竹縣湖口鄉鳳凰村實踐路12號，英文名稱為INFO-TEK CORPORATION，英文簡稱ITC。公司股票於1998年11月18日公開發行、2004年2月23日興櫃、2005年3月30日上櫃。董事長為焦佑衡，總經理為劉貞佑，發言人為黃伯彰。實收資本額為新台幣1,212,510,680元，已發行普通股121,251,068股。公司隸屬華新／PSA華科事業群，主要生產基地包括台灣湖口、江蘇蘇州、昆山及安徽蕪湖；公司官網揭露台灣總部製造基地成立於1990年12月、SMT 5條線，蘇州精華廠成立於2002年1月、SMT 12條線、員工人數1000人以上。2025年4月20日前十大股東資料顯示，精成科技股份有限公司持有33,270,949股、持股27.44%，為最大股東；智嘉投資股份有限公司持有9,985,834股、8.24%；陳美玲持有4,295,317股、3.54%；彭朋煌持有4,080,000股、3.37%；徐幼珍持有1,230,790股、1.02%。2026年5月7日董事會通過與精成科股份轉換案，每1股精星普通股換發0.342股精成科普通股，預計於2026年6月18日股東會討論，若取得主管機關核准，暫定2026年10月1日為股份轉換基準日，完成後精星將成為精成科100%子公司，並申請終止上櫃及停止公開發行；截至本資料基準日2026-06-17，該案仍待股東會與主管機關程序。

Business

精星是專業電子製造服務(EMS)與PCBA廠，主要業務為電子產品組裝加工專業代工，涵蓋SMT表面黏著、PTH傳統插件、測試、組裝與包裝等製程，並提供材料管控、集團中心採購、MRP/JIT物流管理、工程支援、替代料建議、機構與包裝設計、生產與測試治具設計等服務。公司主要產品與應用已由傳統消費性電子與工控轉向汽車電子與新能源車相關PCBA；2026年5月重大訊息與媒體轉載揭露，其重點產品包括電池管理系統模組(BMS)、微控制器MCU、ADAS系統模組、重型機械控制模組等。2025年法說會顯示，2025年前三季營收為新台幣5,140,147千元、年增6.7%，前三季EPS為0.96元；2025年第三季營收1,864,482千元、季增14.6%，第三季EPS 0.99元，較第二季虧損改善。產品線介紹頁揭露BMS/LBMS為主力，合計占比約71%，MCU約10%，ABS/ONE-BOX約9%，ANTENNA AMPLIFIER/ADAS及其他約10%。第三方MoneyDJ資料整理指出，2025年前三季產品別比重約為汽車電子88%、工業控制10%、國防／航空1%、消費性電子1%；銷售地區主要為大陸95%、亞洲3%、歐洲1%、美洲1%。公司官網營收資料顯示，2025全年月營收合計約新台幣72.89億元，較2024年約73.22億元小幅下滑；2026年1月營收692,907千元、年增17.22%，2月494,488千元、年增6.2%。主要客戶未由公司逐一公開揭露；市場資料曾提及中國新能源車電池與整車供應鏈、一線電池廠及整車廠為其下游，但具名客戶需視為市場資料而非公司正式揭露。

Outlook 2025–2028

2025年營運呈現上半年壓力、下半年修復的型態：法說會顯示2025年前三季營收年增6.7%，但毛利率由2024年前三季14.6%降至12.7%，營業淨利率由6.7%降至4.1%，主要壓力來自成本、費用與營業外收支；第三季單季毛利率回升至15.5%、營業淨利率7.5%，顯示產品組合與產能利用率改善。2026年初公司月營收仍呈年增，且截至2026-06-17，公司正面臨與精成科股份轉換案，若通過，精星將整合進精成科PCB與EMS平台，有機會在採購、PCB供應、客戶交叉銷售、車用與新能源車產品線上取得規模綜效。2025至2028年主要成長動能包括：(1)新能源車與中國車用電子滲透率提升，帶動BMS、LBMS、MCU、ADAS、制動域ABS/ONE-BOX等PCBA需求；(2)公司法說會列為新領域的低空經濟(eVTOL、飛行汽車、大型無人機控制器)、氫能燃料電池控制器、氫助力自行車、人形與工業機器人、智能座艙域控與人機互動；(3)兩岸四處產能與可能新增SMT線有助承接汽車電子量產訂單；(4)與精成科整合後，可能利用精成科PCB、EMS與亞洲生產據點擴大規模與降低成本。主要風險包括：(1)客戶與區域集中度高，2025前三季大陸銷售占比約95%，受中國新能源車景氣、價格競爭與政策補貼變化影響大；(2)車用電子要求高可靠度與長認證週期，良率、品質事故與召回風險高於一般消費電子；(3)EMS/PCBA屬代工模式，毛利率受客戶議價、材料價格、稼動率與匯率波動影響；(4)主要客戶未公開，投資人難以精準驗證訂單能見度；(5)股份轉換案若通過，精星可能終止上櫃及停止公開發行，流動性、評價方式與少數股東權益安排是2026年的重大事件風險；(6)法說會前瞻新領域屬公司策略方向，尚未見完整量產營收拆分，2027至2028貢獻仍具不確定性。

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.
