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.

Current PE ≈ 17.59, at the 21.7th 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.

What does 事欣科 do? Company profile

電子業－電腦及週邊設備業；工業電腦、博弈機台、航太及國防製造 上市（台灣證券交易所）

Overview

事欣科技股份有限公司成立於2001/12/27，2013/11/21於台灣證券交易所上市，英文簡稱 PARPRO。公司登記與公開資料顯示總部位於桃園市中壢區領航南路三段188號15樓；年報仍列總公司於桃園市中壢區健行路169號4樓，推測為資料更新時間差異。董事長為廖文嘉，總經理為嚴聰前，發言人吳秀碧。實收資本額依2026年公開股市資料約新台幣1,237,140,730元，已發行普通股約123,714,073股。2024年年報列示截至2025/03/31員工合計739人，其中直接員工447人、間接員工291人、研發人員1人。主要股東依2024年年報截至2025/03/29資料，前十大包含廖文嘉、運永投資有限公司、傑世投資有限公司、派德投資有限公司及其他法人/自然人股東；年報顯示廖文嘉持股約7.21%、運永投資約6.78%、傑世投資約5.27%。公司營運據點涵蓋台灣、美國與墨西哥，近期市場資料指出北美與墨西哥製造布局、ITAR認證與在地化生產是承接美國航太國防訂單的重要基礎。

Business

事欣科定位為少量多樣、高客製化的工業電腦、博弈機台與航太國防零組件/系統製造商，商業模式以OEM/ODM、EMS、合約製造、PCB組裝、線束/電纜組件、鈑金加工、精密加工、子系統組裝與一站式製造服務為主。依2024年年報，2024年合併營收新台幣3,573,442千元，產品結構為航太及國防工業2,311,369千元、占65%，博弈及工業電腦1,262,073千元、占35%；銷售地區高度集中於美洲，2024年美洲銷售3,567,101千元、占99.82%。主要產品包括博弈板卡、準系統、玩家追蹤系統、博弈機台機體及零組件；各類工業電腦主機板卡與零組件；航太及國防應用之線束、電纜訂製、機箱布線、PCB及組裝。年報揭露主要銷售客戶以匿名A公司、Q公司、D公司表示，2024年A公司占13.61%、Q公司占12.80%、D公司占9.78%，未公開正式名稱。近期媒體及法說報導稱公司受惠美系國防、低軌衛星、航太、博弈與通訊客戶訂單，並被市場視為Starlink/SpaceX、軍工與航太相關供應鏈，但單一客戶名稱與占比多未經公司在年報中具名揭露。

Outlook 2025–2028

2025至2028年主要展望可分為四條線。第一，航太國防與低軌衛星：2026/04/15法說會媒體報導指出，截至2026年3月底在手訂單約1.3億美元，約當2025年營收規模，其中航太國防約4成、博弈約37%、通訊約18%；公司看好2026年本業強勁成長，並因處分轉投資股票有業外利益貢獻。第二，產品組合與毛利率：報導稱2025年毛利率升至約20%，公司目標維持20%上下2個百分點；高附加價值航太、國防、衛星與美國在地製造比重提升，有利毛利結構，但仍需觀察是否能穩定轉化為本業營益率。第三，產能與製造布局：公司在台灣、美國、墨西哥分工，近期報導提及北美資本支出、SMT及雷射切割設備，以及美墨產能調配，可能支撐線束、PCB組裝、航太國防與低軌衛星專案交付。第四，產業趨勢：全球國防預算上修、地緣政治、低軌衛星通訊建置、商用航太復甦、AIoT/邊緣運算與自助服務/智慧零售需求，均為中期成長動能。主要風險包括客戶集中且年報不具名、訂單遞延或取消、航太國防認證與ITAR合規要求、匯率與美墨台跨國營運成本、客製化少量多樣導致成本較高、零組件與原物料供應波動、業外利益不可持續，以及市場對SpaceX/美軍等題材可能高估但公司未正式揭露單一客戶營收占比。

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.
