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.

Current PE ≈ 35.63, at the 90.6th percentile of its own history (80-100 band).

光電業;專業商用照明、LED照明燈具 櫃買中心上櫃

Business

湯石為專業商用照明燈具設計與製造商,商業模式以設計代工、專案型照明解決方案、自有品牌並行。主要產品包括LED燈具、HID燈具、螢光燈具、鹵素燈具,並以投射燈、軌道燈、洗牆燈、櫥櫃燈、嵌燈、吸頂燈、戶外投光與景觀照明等高效能商用照明燈具為主。2024年度營收結構為燈具及零件1,216,401仟元,占100%;銷售地區以亞洲634,129仟元、52.14%最高,歐洲487,070仟元、40.04%,大洋洲51,548仟元、4.24%,內銷42,259仟元、3.47%,其他1,395仟元、0.11%。客戶類型包括專業燈光設計公司、燈光工程公司、大型國際燈具品牌廠商及通路商;終端應用涵蓋建築照明、零售展示照明、住宅照明、娛樂照明、戶外照明、商業與工業照明,並延伸至博物館、美術館、精品展售、商辦大樓、飯店、景觀建築與城市戶外照明。公司技術核心在二次光學設計、散熱結構、機構與工業設計、電子驅動與控制系統,戶外產品並強調防水結構、DMX512控制、媒體建築與景觀照明控制。2024年度研發費用89,127仟元,占營收7.33%;2025年第1季研發費用19,039仟元,占營收8.44%。

Outlook 2025–2028

2025至2028年展望偏審慎。中長期正向因素包括全球節能政策、LED滲透率提升、高效率與低碳照明產品需求、城市景觀與建築照明專案、商業空間更新,以及大峽谷併入後帶來戶外景觀照明與中國市場產品線互補。公司2024年報揭露未來研發方向包括LED室內嵌燈與投射燈、戶外高功率高光效洗牆燈與投光燈、替代光源模組、可切換色溫/功率LED燈具、戶外48V串接線條燈、DMX同步控制產品、高光效投光系列等。短期壓力則明顯:2025年受中國內銷市場疲弱、歐洲需求觀望、俄烏戰爭與關稅及地緣政治不確定性拖累,全年營收約9.33億元,年減23.31%,營業損失約1.24億元,稅後虧損約1.04億元,EPS約-1.84元,為2009年以來首度年度虧損。2026年第1季營收約2.17億元,營業虧損約4,700萬元,稅後淨損約2,800萬元,EPS約-0.49元;公司表示訂單能見度約2個月,策略上將從市場、產品、價格與服務調整,深化既有客戶、參與香港與法蘭克福照明展拓展新客源、規劃切入中東市場、提升產品規格與壽命、縮短標準品交期並以彈性報價爭取訂單。2026年主要目標較像是穩住營收、讓虧損收斂,快速轉盈仍需觀察需求回溫、毛利率與費用控管。2027至2028年若全球建築、商業空間投資與中國內需回升,加上低碳照明與景觀照明專案放量,營運有修復空間;但若歐洲景氣、中國房地產與商業投資、匯率、關稅、原物料成本或價格競爭惡化,則復甦可能延後。

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.
