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.

Outlook 2025–2028

2025 至 2028 年主要觀察軸為車用 LED、感測/不可見光 LED、Micro LED 與供應鏈風險。公司 2024 年報指出 2025 年及未來將聚焦車用、感測市場,車用銷售對象主要為中國以外客戶,需求穩定上升;感測應用包括自動化、生物感測與人體監測。產業面,公司年報引用 TrendForce 表示全球車用 LED 市場規模預估由 2024 年 34 億美元成長至 2028 年 49 億美元,車用 LED CAGR 約 8%,不可見光 LED 如 UV LED、IR LED、紅光 LED 需求亦將持續攀升。產品與技術面,公司規劃開發高品質 AlN 磊晶模板、深紫外光 LED、車用可見光 LED、紅外光 LED、點光源 LED、光通訊用 LED、面射型雷射、光電二極體、極小尺寸 LED 晶片與基板轉置產品等;2024 年已開發覆晶 940nm 紅外光 mini LED、高功率 UVC LED、高壓 Mini LED。媒體於 2025 年法說會後報導,公司車用與感測約占營收 75%,車用受電動車及燃油車指示燈、煞車燈、氛圍燈需求帶動,年成長幅度可維持 20% 以上,並與群創合作 Micro LED 技術;但 Micro LED 仍偏研發與中長期布局,距大規模量產貢獻營收仍需時間。主要風險包括 LED 市場成熟與產能過剩造成價格競爭、專利與國際大廠競爭、金價上漲推升貴金屬成本、中國對關鍵基板供應限制使產能利用率受壓、非中國基板來源成本較高、匯率波動,以及車用與 Micro LED 客戶認證和量產時程不確定。

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.
