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.

80-100 159+34.2% +19.1% 75.5% +2.1%

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 ≈ 11.82, at the 2.0th percentile of its own history (0-20 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.

What does 大學光 do? Company profile

生技醫療業 上櫃(證券櫃檯買賣中心)

Overview

3218 對應之證券為大學光學科技股份有限公司普通股,簡稱大學光,於櫃買中心上櫃交易。公司成立於 1994-08-03,公開發行日為 2002-09-13,興櫃日為 2004-01-29,上櫃日為 2004-11-29;統一編號 84926791;總部位於台北市南港區園區街 3-1 號 4 樓。董事長為歐淑芳,總經理為盧政宏,發言人為劉俊杰。官方揭露之實收資本額為新台幣 847,248,990 元,已發行普通股 84,724,899 股。依 2024 年報,截至 2025-03-31 含子公司員工 581 人;2024 年底員工 586 人。主要股東依 2025-03-28 年報揭露包括林丕容 22.75%、瑞利投資 9.00%、群益開發企業 8.87%、核心資本 3.87%、莊明郎 3.28%、信實投資 3.00%,另有外資保管專戶等。公司定位為眼視光與眼科醫療服務整合平台,核心品牌包含 e 大學、大學眼鏡及合作眼科診所體系。

Business

大學光不是單純眼鏡零售商,而是以眼科醫療服務、設備租賃、品牌授權、醫療耗材、顧問及眼鏡商品銷售整合成視力健康平台。2024 年合併營收新台幣 42.283 億元,營收比重為:商品銷售 9.945 億元、23.52%;品牌授權、技術與醫學服務 23.596 億元、55.80%;醫療耗材 5.773 億元、13.65%;顧問收入 1.093 億元、2.59%;租金收入 1.876 億元、4.44%。地區別為台灣 36.346 億元、85.96%,大陸 5.937 億元、14.04%。主要商品與服務包括光學配鏡、隱形眼鏡、保健食品(如大學金三明葉黃素)、視力雷射矯正儀器設備租賃與技術服務、眼科用藥與醫療耗材、合作診所展店裝修與場地租賃、白內障及乾眼檢查治療儀器與技術服務。商業模式上,公司向合作診所提供品牌、醫療設備、耗材、場地與行政後勤,並以直營眼鏡門市承接驗光配鏡、近視防控、保健品與眼健康管理需求。2024 年年報揭露國內合作診所約 29 家、直營眼鏡門市約 32 家;以合作眼科診所飛秒雷射手術眼次估算,台灣雷射視力矯正市場市占約 56%;光學配鏡市場市占約 2%;合作診所每年服務近百萬眼科患者,眼科醫療市場市占估約 5%。主要終端應用為近視雷射、老花雷射、白內障高階自費手術、乾眼治療、學童近視控制、成人多焦舒壓配鏡、隱形眼鏡與眼睛保健。

Outlook 2025–2028

2025 至 2028 年展望可分為四條主線。第一,台灣市場仍是主要成長與獲利來源:2024 年台灣營收占比已升至 85.96%,2025 年公開法說整理顯示台灣占比約 88%,中國占比約 12%;公司策略為持續在台灣展店、升級既有據點及深化眼科診所與眼鏡門市的一站式服務。第二,高階自費醫療是毛利與 ASP 支撐:SMILE、SMILE Pro、SMILE Pro 2.0 全飛秒近視雷射、飛秒白內障、功能型人工水晶體、低眩光長延焦水晶體、乾眼治療及老花雷射均為重點;2025 年起導入 EVO ICL 植入式微型晶片,切入高度近視或不適合雷射患者。第三,視光光學成長動能來自學童近視防控、成人多焦舒壓配鏡、AI/大數據驗配流程及葉黃素保健品;台灣國小與國中視力不良率高、人口老化與 3C 使用時間增加,長期支撐配鏡、白內障與老花需求。第四,中國大陸市場短期偏保守:受消費降級、醫保政策、價格競爭及展店效益不確定影響,公司近年重心回到台灣;2025 年法說整理指出中國以現有據點效率與損益兩平為目標,後續視市場與併購合作機會再決定擴張。主要風險包括:近視雷射同業增加造成價格競爭、高單價自費醫療受景氣與消費信心影響、中國市場復甦不如預期、醫療法規與個資資安要求提高、設備與耗材依賴國際大廠、展店速度過快導致費用率上升。2027 至 2028 的具體營收與 EPS 未見公司正式財測;合理推估是台灣眼健康平台、白內障與近視防控具結構性需求,但成長率將取決於展店效率、新術式滲透率、價格競爭與中國業務止血進度。
