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 1364+0.7% +0.2% 50.9% -13.9%

80-100 112+25.9% +28% 80.4% -23.8%

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 ≈ 16.53, at the 68.0th percentile of its own history (60-80 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.

Overview

寶島科為寶島光學科技股份有限公司,股票代號5312,為台灣上櫃普通股。公司成立於1989年11月9日,前身為華昭科技股份有限公司,1999年更名為寶島光學科技股份有限公司;總部位於新北市汐止區新台五路一段97號16樓。公開資訊與市場資料顯示上櫃日期為1996年5月25日,產業分類為生技醫療業。董事長為蔡國洲,總經理為蔡宜珊。實收資本額為新台幣600,598,980元,已發行普通股60,059,898股,無特別股。114年股東會年報揭露之合併員工人數為2024年底1,454人、截至2025年3月31日1,409人,平均年齡38.3歲、平均服務年資11.2年。前十大股東依114年股東會年報包含:捷富國際股份有限公司10,857,057股、18.07%;寄生股份有限公司5,745,025股、9.56%;陳志勇3,204,558股、5.33%;陳劉惠鈺2,396,975股、3.99%;張陳瑪蓮1,773,522股、2.95%;渣打國際商業銀行受託保管野村信託銀行受託管理富達全球增值股票母基金投資專戶1,565,336股、2.60%;蔡國洲1,335,964股、2.22%;鎧聚投資股份有限公司1,300,972股、2.16%;陳郭照月1,165,422股、1.94%;渣打國際商業銀行受託保管富達低價位股基金投資專戶1,002,000股、1.66%。公司關係企業包含米蘭眼鏡精品企業、寶崴光學、NEW PATH INTERNATIONAL、寶祥光學、寶安視科技等,主要圍繞眼鏡通路、光學商品與醫療耗材。

Business

公司主業為國內眼鏡零售連鎖通路,提供鏡架及鏡片驗光配鏡服務、隱形眼鏡及藥水銷售,並延伸複合式商品如視力保健商品、面膜、助聽器等。114年股東會年報揭露2023年、2024年產品別營收均列為「眼鏡」100%,2024年金額為新台幣3,972,067千元;MoneyDJ產業資料另拆分實務商品結構,指出約30%來自拋棄式隱形眼鏡、70%來自傳統鏡片及鏡架銷售,此拆分屬產業資料口徑而非公司年報正式產品別表。商業模式以直營門市、策略聯盟店、會員經營、驗光專業服務、品牌與商品採購規模為核心,透過大量採購、集中商品系列、自有品牌與獨賣商品、主題行銷與線上會員導流至線下門市提升回購。公司年報指出主要商品以內銷為主,銷售對象為個別消費者,因此無單一主要銷貨客戶。市場地位方面,公司年報估計台灣眼鏡零售市場年銷售值約新台幣260至280億元,全台眼鏡店約4,168家;寶島集團直營店約347家、加計策略聯盟約470家,約占全國總店數11%,為大型連鎖通路龍頭。

Outlook 2025–2028

2025至2026年已可觀察到營收延續成長:公開月營收資料顯示2025年全年合併營收約新台幣41.88億元、年增4.25%;2026年5月單月營收3.8317億元、年增17.43%,2026年前5月累計營收18.73394億元、年增12.85%,公司備註單月及累計營收再創同期歷史新高。2025年EPS資料顯示全年約6.41元,2026年第1季EPS約1.48元、年減26%,代表營收動能與獲利率、費用結構仍需分開觀察。2025至2028成長動能主要來自:台灣近視人口與配鏡剛性需求、青少年高汰換率、銀髮族多焦點與老花需求、拋棄式與彩色隱形眼鏡、驗光人員專業化帶來的連鎖通路整合、會員資料庫與線上線下整合、門市汰弱留強與二代店/年輕化裝潢、策略聯盟轉直營或提升控制力、上游品牌代理與製造垂直整合。公司年報列示短期計畫包括強化驗光人員證照與專業訓練、提供多焦點/兒童視力保健/高曲度運動鏡片等高技術含量商品、開發年輕市場、定期舊客活動、差異化包裝與獨賣商品、檢討低效門市、重視庫存周轉與供應價格;長期計畫包括會員數據分析、提高市占率、向上游品牌代理及製造整合、評估亞洲市場機會。主要風險與挑戰包括:台灣眼鏡零售市場成熟且總店數可能下降、低價化與快時尚國際品牌競爭、國際鏡片/隱形眼鏡品牌談判力可能壓縮通路毛利、租金與人事成本上升、驗光人員法規與人才取得、消費景氣轉弱、門市展店或改裝折舊費用、利率上升造成租賃負債與財務成本壓力,以及公司持有金融資產或轉投資對業外損益波動的影響。2027至2028具體財測未見公司正式量化指引,本段對2027至2028之判斷為依年報策略、產業結構與最新營收趨勢所作之研究推估。

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.
