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
20-40 123+25.9% +20.6% 100% +0.3%

60-80 32-19.8% -20.2% 0% -61.3%
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 ≈ 81.82, at the 83.9th 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.

Business

建舜電主要從事線裝類含連接器、電子產品、天線與外接式儲存裝置等產品之設計、研發、製造與銷售,核心能力為客製化連接線組、連接器、高頻高速訊號線、USB Type-C、USB4、Thunderbolt、HDMI、SATA/eSATA、AOC、Wire Harness、天線、醫療線材與電子週邊產品。依114年度年報,2025年合併營收新台幣3,004,391仟元,年增6%;合併毛利413,308仟元,營業淨損106,644仟元,每股稅後虧損0.96元。2025年產品營收結構為:線裝類含連接器2,415,389仟元,占80.39%;外接式儲存裝置138,693仟元,占4.62%;其他450,309仟元,占14.99%。銷售地區以外銷為主,2025年內銷236,387仟元、占7.87%,外銷2,768,004仟元、占92.13%。商業模式以國際電子品牌、系統廠、電子組裝廠及週邊設備客戶的客製化共同開發、NPI導入、量產製造與三角貿易為主;公司在連接線與連接器領域深耕多年,主要與下游客戶研發單位共同設計符合高速傳輸、充電、機構空間、可靠度與驗證需求的產品。年報揭露主要客戶群為數位相機大廠及全球電子組裝廠等國際級製造廠商,但實際客戶名稱以A、B、C、D客戶匿名揭露;2025年前三大10%以上客戶分別占25.35%、11.52%、10.30%,最近兩年度10%以上銷貨客戶皆為長期合作客戶。公司近年產品重心由傳統消費電子連接線,逐步轉向USB4、Thunderbolt 5、AI伺服器高速線、雲端儲存、邊緣運算、工控與醫療器材線材等高附加價值應用。

Outlook 2025–2028

2025年為建舜電產品轉型與高速線材認證量產的關鍵年:年報揭露2025年開發Thunderbolt 5 Passive Cable同軸0.8至1.5m、Thunderbolt 5 Passive Cable對絞0.3至0.8m、Thunderbolt 5 Active Cable同軸2.0m、USB4 to PCI-e M.2 SSD、Wi-Fi extend與NAS for Media等;公司2025年營收年增6%,但仍因毛利與費用結構承壓而虧損。2026年營運計畫重點為深耕高頻線材及連接器、推動豐田式管理與自動化、優化泰國與中國各廠策略分工、開發國際大廠客戶、拓展醫療器材與工控等非消費性電子零組件。產業面,AI PC滲透率提升、USB4 Gen3/Gen4與Thunderbolt 5等高速介面需求、AI伺服器與邊緣運算硬體的高速背板連接器及大電流線材需求,均有利於公司高階線材產品滲透;公司亦受惠於歐美客戶去中國化與在地化供應鏈需求,泰國廠及泰國二期新廠可作為高速線材與綠色製程據點。2026至2028年成長動能可概括為:Thunderbolt 5與USB4高速線材量產放大、AI伺服器內部線與雲端儲存線材導入、醫療與工控線材應用擴張、泰國產能與中國東莞/蘇州/湖北基地分工提升、垂直整合與自動化改善成本。主要風險包括:2025年仍處虧損、產品組合與良率改善速度不確定;年報揭露最大單一客戶2025年占銷貨淨額25.35%,客戶集中度需觀察;原材料如連接器、銅線、鍍銀硬銅價格波動與同業削價競爭可能壓縮毛利;中國同業價格競爭、勞動成本與供應鏈轉移成本、關稅與地緣政治、PFAS與CBAM等環保法規、AI伺服器客戶驗證與量產時程不確定,皆可能影響2026至2028年實際成長。
