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 85+56.9% +23% 70.6% +15.1%
20-40 255+58.1% +42.4% 73.3% +9.4%

80-100 You are here110-21.9% -25.9% 10% -32.5%

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 ≈ 72.5, at the 97.7th 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 友威科 do? Company profile

其他電子業;半導體與電子製程設備、真空濺鍍設備、乾式電漿蝕刻設備、真空鍍膜代工 上櫃(櫃買中心,TPEX)

Overview

3580 對應證券為友威科技股份有限公司,簡稱友威科,為櫃買中心上櫃普通股。公司成立於 2002/11/04,股票於 2010/07/09 上櫃。董事長為李原吉,總經理為劉品均,發言人為陳繼萱。公司地址為桃園市蘆竹區長興里厚生路 51 號 6 樓,官網為 https://www.uvat.com。主要經營業務為濺鍍 Sputter、蝕刻 Etch、真空鍍膜代工 Vacuum Coating Service。鉅亨與公司法說資料顯示資本額約新台幣 3.94 億元;2025/12/24 法說簡報列示資本額新台幣 3 億 9,470 萬元、員工台灣約 120 人、海外約 150 人;2025 年報則列示 2025 年員工合計 190 人、2026 年截至 3 月底 191 人,平均年齡約 40 歲、平均服務年資約 10.57 年。公司官網揭露 2025/03/29 前十大股東為:李原吉 5.85%、佑兆投資有限公司 2.71%、花旗託管柏克萊資本 SBL/PB 投資專戶 1.66%、嵇宇聲 1.39%、中國信託商銀受友威科技股份有限公司員工持股會信託財產專戶 0.81%、林火烈 0.63%、李翠英 0.62%、張皓翔 0.51%、余景仁 0.51%、張清泉 0.50%。2025 年合併營收 4.32068 億元,合併稅後淨利 7,639 萬元,EPS 1.94 元;2024 年 EPS 5.08 元。2025 年底合併資產 17.8449 億元、負債 7.5577 億元、股東權益 10.2872 億元,自有資本率 58%。

Business

友威科核心為乾式真空製程解決方案,整合真空濺鍍與電漿蝕刻兩項技術,業務包含真空濺鍍設備、乾式電漿蝕刻設備、半導體設備及相關耗材、真空鍍膜代工、光學鍍膜與薄膜元件。公司以設備銷售與代工服務雙軌營運:設備端應用於半導體封裝、IC 載板、被動元件、光學 5G 蓋板、汽車零組件、3C 外觀與功能性鍍膜等;代工端以 NB 與 3C 消費性電子 EMI 防電磁波干擾鍍膜、觸控面板 AR/AF/ITO 薄膜、IC 載板鍍膜、裝飾性鍍膜等為主。2025/12/24 法說簡報揭露,2025 年設備營收占比達 74%,其中半導體設備達 65%;2025 年 CoWoS 營收占比首度超越 FOPLP 產品。年報揭露 2025 年設備銷售比重約七成,因設備單價高,三家未具名客戶分別占全年銷貨淨額 22.89%、15.88%、10.41%;2024 年亦有 A、B 客戶占比 39.28%、16.86%。公司因合約約定未揭露客戶實名。產品價值主張在於以真空濺鍍替代部分傳統水電鍍或印刷銅等製程,具低成本、高量產性與較符合環保趨勢等特性;在半導體先進封裝方面提供 CoWoS 所需細線路電漿蝕刻、介電材薄化蝕刻、細線路金屬蝕刻,以及 FOPLP 種子層濺鍍、面板級封裝相關設備。

Outlook 2025–2028

2025 年為營運下滑與產品結構調整年:年報指出美國關稅政策不確定性與地緣政治風險使部分客戶重大資本支出進度調整,設備業務成長放緩,全年營收較 2024 年下降;但產品組合持續優化、高附加價值應用比重提升,毛利率較具支撐。2026 年展望重點為 AI、HPC 與先進封裝需求延續、CoWoS 與 FOPLP 設備需求,以及台中新企業總部投產。公司法說簡報與 MoneyDJ 報導均指出台中大雅新企業總部預計 2026 年第三季正式投產,預計產能達現有 5 倍以上,並擴大半導體研發中心;MoneyDJ 2026/06/01 報導稱預計 2026 年 8 月展開搬遷、第三季啟用,可用廠房面積估較目前增加 75%。公司年報也提到將加速拓展歐美、日韓等海外市場,強化馬來西亞在地服務,並透過德鑫半導體聯盟布局美國與日本。2027 至 2028 年的中期動能主要推估來自 AI 晶片帶動 CoWoS、FOPLP、CoWoP、玻璃基板/TGV 與高階載板相關濺鍍、乾式蝕刻、電漿清潔設備需求,及新廠產能利用率提升;但公司未提供 2027-2028 財務預測。主要風險包括:客戶資本支出遞延、設備客戶集中、客戶與訂單驗收時點造成營收波動、半導體景氣循環、海外市場拓展不確定、匯率波動、關稅與地緣政治、先進封裝量產時程與良率、以及新廠投產後折舊與資金需求壓力。

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.
