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 48+7.5% +4% 83.3% -56.6%

80-100 You are here83-1.4% +3.3% 53% -20.9%

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 ≈ 13.49, at the 87.4th 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.

捷流是工業流體控制閥門廠,產品包括蝶閥、球閥、控制閥、逆止閥、低負載蝶閥、閘閥、特殊閥,以及外購閥、執行器、訊號反饋、量測儀表與相關系統整合服務。2024年營收新台幣2,402,500仟元,產品結構為蝶閥1,412,942仟元、占58.81%;外購閥926,010仟元、占38.54%;其他63,548仟元、占2.65%。區域結構為內銷1,400,952仟元、占58.31%;外銷1,001,548仟元、占41.69%,其中大陸含香港23.85%、亞洲其他5.53%、歐洲8.38%、美洲3.05%、非洲0.98%。2025年上半年依新聞引述公司說法,終端產業營收占比為半導體暨電子40.19%、石化30.38%、船舶10.49%、工程暨水處理7.05%。商業模式由自製高階蝶閥與球閥、代理或外購其他閥件、售後維修、工程整合與客製化解決方案組成;公司強調一站式採購、閥門與控制元件整合、供貨、安裝、測試、運轉與維護。終端應用涵蓋石油、石化、鋼鐵、造船、能源、水處理、造紙、空調、半導體與電子廠務等。年報揭露2024年10%以上客戶以A公司、B公司代號呈現,A公司2024年銷售額241,337仟元占10.05%,B公司253,223仟元占10.55%,未揭露實名。

Outlook 2025–2028

2025年:公司於2025年法說及新聞報導中表示,上半年受匯兌損失、關稅不確定性與部分客戶延後拉貨影響,出貨不如預期;2025年上半年營收約11.37億元、毛利率29.74%、稅後純益9,815萬元、EPS約2.16元。公司預期隨關稅因素穩定、延後訂單於下半年出貨,下半年營運優於上半年,全年業績大致維持2024年水準;整體訂單能見度約6個月。主要動能來自半導體與電子廠務擴建、石化需求復甦、船舶與水處理訂單。2026年:公司公開說法提到2026年業績目標可持續成長,成長基礎包括半導體廠持續建置、石化海內外擴產、船舶壓艙水與脫硫等環保需求,以及美國水處理用閥門訂單。2027至2028年:未查得公司正式量化財測,僅能依產業趨勢推估;工業閥門市場受全球製造業自動化、能源與水處理基礎建設、半導體廠房擴張、製程安全與低洩漏規範推動,捷流若能持續取得API、ABS、BV、DNV、TÜV等認證並提高高溫、高壓、低溫、低逸散、耐腐蝕高階閥門占比,仍有機會維持成長與較佳毛利。主要風險包括新台幣匯率波動、關稅與貿易政策、石化與鋼鐵資本支出循環、半導體客戶擴廠時程遞延、大陸與東南亞低價競爭、鑄件與鋼材供應及成本、重大客戶訂單集中、外購閥比重提高可能壓縮毛利,以及工業安全認證與品質失誤風險。

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.
