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.

80-100 You are here221-4.2% -7.8% 22.2% -48%

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 ≈ 180.29, at the 91.5th 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.

What does 銘鈺 do? Company profile

電子零組件業 台灣證券交易所上市

Overview

4545 對應證券為銘鈺,為台灣證券交易所上市普通股,產業類別為電子零組件。公司成立於 2001 年 1 月 18 日,上市日期為 2016 年 1 月 6 日,總部位於桃園市觀音區國瑞路 2 號,董事長為謝錦興,總經理為方光義,發言人為財務主管蕭佳伶。2026 年 5 月法說會揭露實收資本額為新台幣 7.7 億元,員工人數約 850 人,集團總部位於桃園市觀音工業區。集團投資架構包含台灣銘鈺精密、薩摩亞 Esteem King、新加坡 MAP Plastics、中國蘇州億模、馬來西亞 MATC 等,業務分別涵蓋精密金屬沖壓、醫療用塑膠射出與自動化業務。2026 年 4 月股權結構為銘異科技 38.8%、Beacon Investments Limited 27.0%、員工及其他外部股東 32.8%、董事及經理人 1.4%;另 2025 年股東會年報前十大股東相互間關係表顯示,銘異科技持股約 38.78%、Beacon Investments Limited 持股約 29.55%、台灣福興持股約 1.95%,其餘包括王崇吉、方光義及保管銀行專戶等。

Business

銘鈺為精密金屬沖壓、醫療塑膠射出與自動化設備製造商。主要產品包括硬碟機用精密金屬沖壓件,如音圈馬達上下板、Disk Clamp、Balance Weight、Insert Plate、Bobbin、Stiffener、Top Cover、Pin 等;電子沖壓零組件與散熱片產品,散熱片以銅底金屬沖壓成形並搭配噴砂、電鍍鎳、氧化矽、鍍金等表面處理,應用於高階伺服器、通訊機與消費性電子;醫療與生化實驗用耗材、醫院護理產品、日常保養相關塑膠射出件;自動化設備包含自動貼標機、自動包裝機、AOI 檢測機台、自動貼膜機與測試工裝。2026 年 5 月法說會揭露 2025 年營收新台幣 23.8766 億元、EPS 0.17 元,2026 年第一季營收 5.28259 億元、EPS 0.21 元。營收來源方面,2026 年第一季硬碟機沖壓零組件約 40%、電子沖壓零組件約 29%、塑膠射出件約 21%、自動化機台約 4%、其他約 6%;同一簡報呈現硬碟機沖壓零組件仍為最大營收來源,且 2023 至 2026 年第一季占比約 49%、60%、63%、69% 的圖表讀值疑似代表精密金屬沖壓相關合計或圖表堆疊資訊,因簡報文字未完整標示,採保守解讀。商業模式為承接國際硬碟、伺服器、PC、醫療耗材與自動化設備客戶的客製化設計、開模、精密沖壓、表面處理、無塵室組裝與量測服務。公開資料顯示其硬碟客戶涵蓋 Western Digital 與 Seagate,並通過世界前三大硬碟廠、台灣封測大廠、半導體大廠及國際品牌手機客戶認證。

Outlook 2025–2028

2025 至 2028 年展望重點在 AI 資料中心與高容量 HDD、CPU 均熱片、醫療塑膠與非 3C 自動化應用。公司 2026 年 5 月法說會與媒體報導指出,AI 資料中心仍大量使用傳統硬碟,Nearline HDD 高容量化、厚度提升與伺服器用高階 HDD 將支撐硬碟沖壓件單價與營收;銘鈺稱全球硬碟零組件市占率約三成,客戶含 Western Digital 與 Seagate。均熱片方面,AI 運算推升 CPU 散熱需求,公司均熱片產品供應 PC 與伺服器 CPU 應用,伺服器產品尺寸較大、材料成本與加工費較高,對營收與毛利貢獻較佳;2026 年下半年均熱片產能預計擴增 30% 至 50%,未來兩年仍將新增產線與添購大噸數沖壓設備,且均熱片業務占營收已達約 2 至 3 成、下半年有機會提升至約 30%。醫療用塑膠射出件因認證門檻高、需求相對穩定,為中期穩定來源;自動化設備過去偏 3C,因中國 3C 需求下行,公司轉向非 3C 應用,但非 3C 單價較低,短期營收貢獻可能較平穩。主要風險包括 HDD 長期受 SSD 替代壓力、少數國際大客戶集中、銅價與鋼材等原料價格波動、匯率波動、設備到位與新產線稼動率不如預期、散熱片與均熱片競爭加劇、客戶產品切換造成加工效率下降,以及公司未發布正式財務預測,2027 至 2028 年展望多屬依產業趨勢與公司擴產規劃推估。

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.
