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)
0-20 229-23.1% -34% 21.4% -34.8%

80-100 280-19.4% -20.1% 5.7% -38.3%

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 ≈ 22.46, at the 48.7th percentile of its own history (40-60 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.

電機機械業;汽車零組件 上櫃

Overview

8107 對應證券為上櫃普通股「大億金茂股份有限公司」,英文名 TAYIH KENMOS AUTO PARTS CO., LTD.,非 ETF、ETN、權證或特別股。公司成立日為 1998-01-05,原名大億電子/大億科技,早期由大億企業集團與日本 Stanley 電氣株式會社共同創立,主要從事液晶顯示器背光模組;因面板產業環境艱困,2013 年起提高汽車零組件營收比重,2014 年全面朝汽車零組件轉型,2015 年淡出背光模組並與金茂工業合併,2017-02-06 與子公司大億金茂合併,2017-06-07 股東會決議更名為大億金茂股份有限公司。總部/登記地址為台南市南區新樂路39號,電話 06-2650688。董事長吳俊億,總經理陳俊宏,發言人劉茵姍。上櫃日期 2005-11-15,實收資本額新台幣 750,000,000 元,普通股 75,000,000 股,特別股 0 股,簽證會計師事務所為資誠聯合會計師事務所。員工規模依 113 年年報:2025-03-31 合計 429 人,其中直接人員 261 人、間接人員 168 人,平均年齡 38.17 歲,平均服務年資 6.63 年。前十大股東資料依 2025-04-22 停止過戶日年報揭露,主要包括大緯投資企業 16,861,281 股、22.48%,鼎丸投資興業 7,386,718 股、9.85%,呂金發 2,302,000 股、3.07%,運賢企業 2,250,490 股、3.00%,另有宸旺興業、啟敏投資、花旗台灣商銀受託保管瑞銀歐洲 SE 投資專戶等;法人股東背後多與大億集團/吳氏家族投資公司相關。公司另持有皇田工業 9951 股權約 12.62%、大億金茂泰國 100%、Kenmos Technology Samoa 100%、廣育電子 51% 等轉投資。

Business

主要業務為汽車零組件製造與買賣,核心產品為汽車外觀零組件與濾材。公司官網列示主要經營業務為車用中空成型件、濾材等;產品頁列示濾網、側踏板、皮卡後車斗飾件,濾網產品含車用冷氣濾網、自動變速箱濾網、家用空氣清淨機濾網、口罩/面罩用活性碳不織布等。113 年年報產品營收比重:車用外觀件新台幣 661,282 仟元、71.60%;活性碳濾材 68,467 仟元、7.41%;其他 193,860 仟元、20.99%;合計營收 923,609 仟元。外觀件業務包括車用後車斗護欄、腳踏板、擾流板,主要搭載於中小型貨卡/皮卡車;濾材業務包括車用冷氣濾材。商業模式以汽車 OEM/OES/AM 為主,其中年報稱公司位於國際車廠供應鏈 Tier 1,OEM 與 AM 比重約 90:10,產品已對美系及日系大廠穩定交貨,並積極開發東南亞及中南美洲市場。銷售區域高度外銷:113 年內銷 52,052 仟元、5.64%,外銷 871,557 仟元、94.36%。主要客戶年報以 B/E/D/F 公司匿名揭露,113 年前四大客戶占銷貨淨額分別約 35.97%、27.88%、14.39%、10.45%,皆與發行人無關係;MoneyDJ 與公司沿革提及曾與 Ford、GM 等美國車廠合作開發皮卡後貨斗護欄產品,104 人力銀行亦稱產品銷售遍及歐美、中東、東南亞且包含 Ford 等 OEM 汽車大廠。2024 年營收年增 38.07%,主因車用外觀件受惠新車型導入與訂單需求增加;2025 年董事會通過財報公告顯示全年營收約 9.43 億元、歸屬母公司淨損約 4,002 萬元、EPS -0.53 元;2026 年第一季 Goodinfo/市場資料顯示營收約 2.1 億元、EPS 約 0.03 元,2026 年前五月營收約 2.92 億元、年減約 30.06%,顯示 2026 年初營收動能較 2025 同期偏弱。

Outlook 2025–2028

2025-2028 展望以年報既有策略與產業趨勢推估,非公司正式財測。成長動能包括:一、汽車外觀件新車型導入與國際車廠 OEM 訂單,公司 2024 年營收回升主因即為新車型導入與訂單增加;二、以泰國為基地布局東南亞汽車零組件市場,降低運輸與關稅成本,貼近車廠供應鏈;三、濾材產品升級,包含提升車用濾網材質與過濾效能、開發新型功能濾網,活性碳濾材與 PM2.5 等級濾材受空氣品質與車用耗材需求支撐;四、車用小燈生產整備與燈具事業拓展,若能取得國際客戶導入,可增加產品線;五、集團在 OEM 與 AM 通路的資源整合,有助濾網外銷與交叉銷售。產業趨勢方面,汽車零組件走向輕量化、塑膠材料替代金屬件、車聯網/智慧車/自動駕駛帶動整車與零組件供應鏈重組,車廠降低自製率並仰賴外部零組件廠研發協作,長期有利具認證與 Tier 1 供應能力者。主要風險與挑戰包括:一、客戶與銷貨集中,年報揭露前四大客戶占比高,公司需持續分散銷貨集中風險;二、進貨集中與原料價格,主要供應商包含鋁擠型配件、塑膠粒、漆料供應商且占比高;三、價格競爭與其他生產工法競爭,可能影響訂單取得;四、地緣政治、中美關稅戰、保護主義與各國提高汽車零件自製率,可能迫使公司就近設廠並提高資本投入;五、美元應收帳款與匯率波動、利率與運輸/能源/人力成本上升;六、2026 年前五月營收年減顯示短期拉貨與終端需求有下行風險。整體判斷:若泰國廠稼動率、新車型接單、濾網外銷與車用小燈導入順利,2025-2028 有機會維持汽車零組件轉型後的中長期成長路徑;但因公司規模小、客戶集中與年度營收波動大,展望能見度屬中等偏低。
