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 0Insufficient data

80-100 You are here180+123.6% +154.7% 87.8% +64.4%

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 ≈ 85.0, at the 98.2th 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

公司核心本業為電子零件、電子材料之製造加工及進出口貿易,主要產品為變壓器線架、塑膠類與電木類工程製品,屬被動電子元件零組件製造鏈中的變壓器/線圈上游結構件。公司變壓器線架主要分為傳統 DIP 型與表面黏著 SMD 型;DIP 型應用於電源供應器、CRT 顯示器、電源轉換器、手機充電器與消費性家電,SMD 型應用於 LCD 監視器、LCD TV、筆記型電腦、掃描器、數位相機、通訊器材與 PDA 等。依 2025 年合併財報,2025 年營業收入淨額為新台幣 168,527 仟元,其中變壓器線架 160,899 仟元、約 95.47%,冷凍肉品 7,628 仟元、約 4.53%;2024 年營業收入淨額為 182,689 仟元,全部為變壓器線架。2026 年第一季營業收入淨額為 42,210 仟元,其中變壓器線架 37,434 仟元、約 88.68%,冷凍肉品 4,776 仟元、約 11.32%;2026Q1 塑膠電子事業部部門收入 37,434 仟元、部門損益 5,405 仟元,冷凍豬肉事業部收入 4,776 仟元、部門損益為虧損 7,676 仟元。2024 年主要銷售地區為中國,占 100%。主要客戶集中在電子製造與變壓器/電源相關客戶,2024 年主要客戶包括 Therm-O-Disc Inc.(Delicisa Mexico)銷售額 57,598 仟元、31.53%,Power Supply Technology 38,737 仟元、21.20%,聖衡斯科技(珠海)15,778 仟元、8.64%;2025Q1 三者占比分別為 31.16%、23.03%、12.45%。2025 年起新增豬肉相關產品銷售營業活動,模式包含每日於肉品市場拍賣購入毛豬,屠宰及大分切後批發銷售給冷藏/冷凍豬肉加工廠與傳統市場業者,以及自國外尋找政府批准且信譽良好的供應商進口冷凍豬肉,銷售予中下游食品製造及供應業者。

Outlook 2025–2028

2025 至 2028 年展望可分為本業修復、多角化與風險控管三條主線。第一,本業方面,公司年報指出將持續加強電子產業新產品與新客戶開發、提高高毛利客戶銷售額,並透過檢視低毛利訂單、議價或篩選汰除,提高整體毛利;研發方向包含變壓器線架零組件、TOD 溫控器機種及連接器、車載相關部品、耐高壓精密及輕薄短小變壓器線架、自動化生產與一模多穴模具設計。第二,產業面,公司年報認為 AI 伺服器在運算、功率、散熱與機構規格上的差異,將衍生電路板、電源供應器、被動元件、散熱模組與機殼等零組件商機;但雲嘉南目前主要產品仍是變壓器線架,能否實質切入 AI 伺服器供應鏈仍未有明確公開訂單證據。第三,多角化方面,公司 2025 年已新增毛豬屠體分切與冷凍豬肉進出口銷售事業,管理層目標是大幅提升營業收入、轉虧為盈;但 2026Q1 冷凍豬肉事業部仍為虧損,需觀察規模、毛利與存貨/價格風險。第四,財務與特殊事項方面,2025 年全年 EPS 轉正主要受處分和昌未來科技(深圳)有限公司產生處分投資利益 50,762 仟元影響,屬一次性業外利益,不能視為本業已穩定轉盈;2026Q1 又轉為每股虧損 0.32 元,顯示營運仍在調整期。主要風險包括客戶訂單趨緩、全球原物料價格上升、變壓器線架競爭激烈且技術門檻較低、下游客戶外移中國及東南亞、最大客戶與前十大客戶應收款項集中、低毛利訂單壓縮獲利、豬肉業務跨入食品與進口貿易後面臨價格波動、存貨、食品安全與通路開拓風險,以及中國子公司歷史訴訟、稅務行政訴訟與公司治理改善進度。2027 至 2028 年公司未公告正式財測,故中長期成長需以新客戶開發、高毛利訂單占比、豬肉業務是否放量且轉正、以及訴訟/稅務不確定性是否下降作為追蹤指標。
