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
40-60 You are here0Insufficient data
60-80 150-16.6% -22.3% 18.7% -25.9%
80-100 240-2.9% -0.8% 47.9% -36.5%

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 ≈ 68.25, at the 55.0th 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.

Business

匯鑽科是專業表面處理服務商,商業模式以接受客戶委託,對金屬或塑膠零組件提供客製化表面處理加工、製程開發、品質檢驗與相關環保/自動化/管理配套諮詢為主。主要製程包含化學鎳、滾鍍、電鍍錫鎳、鍍銀、鍍錫、鍍鋅、鍍金、清洗、磷化、鈍化、珍珠鎳、光學黑化鎳、散熱型半光亮鎳金、複合型多層次局部連續鍍、精密拋光無電解鎳等。官網揭露主要應用涵蓋 HDD 硬碟、電子、散熱、精密儀器、車用、醫療與半導體導線架/端子/料帶/LED 支架等。MoneyDJ 資料指出 2024 年產品收入幾乎全為加工收入,應用端以硬碟約 39% 為最大,其餘為連接器、3C 產品、醫材、汽車等;公司主要銷售區域為外銷,2024 年外銷比重約 99%。硬碟客戶包括 Seagate、Western Digital、Toshiba 等國際 HDD 業者,其中 Seagate、WD、Toshiba 合計為全球 HDD 主要廠商;MoneyDJ 並稱匯鑽科是 Seagate 在中國大陸地區認證合格之硬碟驅動臂表面處理專業廠商。家電端曾與 DeLonghi-Kenwood 集團合作,為 Braun 熨斗底板提供電鍍加工;車用端提供車用螺絲、螺帽、引擎噴嘴及 IGBT/散熱模組相關表面處理;電子與 3C 端則包含連接器、Type-C、端子、手機與高階 3C 外觀/功能性表面處理。公司競爭優勢在於國際大廠認證、客製化共同開發能力、深圳/東莞與泰國排污許可量及自動化檢測與生產能力;官網揭露中國深圳/東莞環評排污執照總量約 1000 噸/日、泰國大城地區約 600 噸/日。

Outlook 2025–2028

2025 年公司處於轉型陣痛期。公開新聞指出 2025 年全年營收約新台幣 10.46 億至 10.56 億元,年增約 1.57% 或小幅成長,但受泰國、越南新產能布局、技術升級、新製程導入、人力與折舊成本、產品組合與毛利率下滑影響,2025 年由盈轉虧,稅後虧損約 1.84 億至 1.87 億元,EPS 約 -3.88 至 -3.94 元,董事會決議不配發股利。2026 至 2028 年主要成長動能在三個方向:第一,AI 伺服器與資料中心帶動高容量 HDD 需求,使傳統 HDD 零組件表面處理仍有基礎訂單支撐;第二,AI 伺服器水冷散熱、散熱模組、矽光子/光通訊零組件所需之鍍金、防蝕、低熱阻與高可靠度表面處理,可能成為高毛利新業務;第三,手機、折疊手機、碳纖維複合材料、Type-C 連接器、車用 IGBT 散熱模組、醫療與精密儀器等應用可分散 HDD 長期成熟化風險。公開新聞指出泰國新廠聚焦 AI 水冷散熱模組與光通訊產品,曾報導預計 2026 年第 2 季或第 4 季完工/量產,完工量產後產能可增加一倍以上;越南廠則規劃專注 AI 伺服器與醫療等零組件。中長期挑戰包括:新廠完工與客戶認證時程不確定、產能利用率拉升前固定成本與折舊壓力、金屬與化學品原料價格波動、環保法規與排污限制、HDD 長期受 SSD 替代、3C 與連接器價格競爭、匯率波動、中國/泰國/越南跨國管理與供應鏈地緣政治風險。2026 至 2028 年若新產品認證、AI 散熱/光通訊量產及越南/泰國產能利用率順利提升,毛利率有機會較 2025 年低點修復;反之若訂單延遲或新製程良率不如預期,虧損與現金流壓力可能延續。

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.
