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.

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 ≈ 42.75, at the 99.9th 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

晶技定位為專業頻率控制元件供應商，核心產品為石英諧振器 Crystal Units、石英振盪器 Crystal Oscillators，以及溫度補償、壓控、恆溫控制、kHz/MHz、車載規格、溫度感應石英諧振器等頻率元件。產品用途涵蓋行動通訊、穿戴式裝置、物聯網、智慧家庭、電信與企業網路、光收發模組、伺服器、交換器、智慧網卡、儲存運算設備、人工智慧、高效能運算卡、醫療、車用電子、電動車、ADAS、車用資訊娛樂、車用通訊、胎壓偵測與安全配備等。商業模式為自有研發、製程與多地製造，供應高精密、高品質頻率元件給手機、網通、伺服器、光通訊、車用與工業/醫療等客戶鏈。公司官網揭露 2025 年 AI 營收佔比 10.2%，年增 2.8 個百分點；車用營收佔比 25.9%，年增 4.3 個百分點。MoneyDJ 整理資料顯示 2024 年銷售地區約台灣 4%、亞洲 92%、歐美 4%；主要原料包含基座、上蓋、IC Package、晶片、晶棒等，向國內外兩家以上供應商採購。2025 年月營收合計約新台幣 133.49 億元，較 2024 年 126.72 億元成長；2026 年 1-5 月外部券商資料列示累計營收約新台幣 58 億元、年增約 10.5%，顯示 AI、網通與車用應用仍支撐需求。

Outlook 2025–2028

2025 年已由公司官網確認全年營收新台幣 13,349 百萬元、稅後淨利 1,805 百萬元，AI 與車用營收佔比分別達 10.2% 與 25.9%，反映產品組合逐步從傳統手機/消費電子轉向 AI、網通、光通訊與車用電子。2026 年截至 5 月累計營收約新台幣 58 億元、年增約 10.5%，主要觀察點為 AI 資料中心、800G/1.6T 光收發模組、AI 交換器、伺服器、智慧網卡，以及車用 ADAS、Level 3 以上自駕趨勢對高頻、低抖動、高穩定度石英元件的需求。公司 2024-2025 年新增海外產能包含浙江寧波車用頻率元件生產基地與印尼新生產基地，寧波車用專廠已投產，印尼基地於 2025 年首季投產並拉升產能，利於分散製造基地、服務車用與國際客戶。2027-2028 年中期動能預期來自 AI 光通訊升級、AI 伺服器網通規格提升、車用電子化/電動化/自駕化、低軌衛星與高階工業/醫療頻率元件需求，但公司未正式提供 2027-2028 財測，相關年期判斷屬產業趨勢推估。主要風險包括：智慧手機成熟市場需求波動；美系客戶部分機種改採 MEMS 振盪器造成石英振盪器用量壓力；中國車用市場競爭與價格壓力；客戶庫存與提前拉貨後的修正；AI 光通訊需求若不如預期，將影響高階產品成長；匯率、原料、良率、海外廠量產爬坡與車規認證周期也會影響毛利與出貨節奏。

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.
