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.

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)
0-20 103+16.7% +18.9% 100% -6.3%
20-40 255+14.7% +7.5% 65.1% -9.4%

80-100 641+20.6% +21.8% 85.5% -5.3%

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 ≈ 13.17, at the 62.4th 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.

What does 光聯 do? Company profile

光電業;中小尺寸 LCD/LCM/觸控面板模組 櫃買中心上櫃

Overview

5315 對應證券為光聯科技股份有限公司普通股,於櫃買中心上櫃交易,股票簡稱光聯。公司成立於 1990 年 6 月 26 日,掛牌上櫃日期為 1996 年 11 月 2 日,總部位於台中市潭子區潭子科技產業園區建國路 12 號。公開資料顯示董事長為陳江源,總經理為葉建文,發言人為林珂如。實收資本額為新台幣 1,063,518,320 元,已發行普通股 106,351,832 股。114 年度年報揭露從業員工 448 人,平均年齡 43.99 歲,平均服務年資 13.94 年。115 年 3 月 24 日主要股東包含渣打託管列支敦士登銀行 3.62%、易百益投資有限公司 3.47%、花旗託管柏克萊資本 SBL/PB 投資專戶 2.63%、葉秋芳 2.34%、聯騏投資有限公司 2.06%、葉怡雯 1.88%、葉建文 1.68%、黃于倢 1.51%、楊健義 1.50%、匯豐(台灣)商業銀行受託保管帳戶 1.39%。法人股東聯騏投資有限公司之主要股東為葉建文;年報中易百益投資之股東結構欄位擷取不完整,未進一步推定。

Business

光聯為利基型中小尺寸顯示器與模組廠,主要產品與服務包含 LCD 顯示器、LCM 液晶顯示器模組、TP 觸控面板、光學貼合、系統板/轉接板與整機整合方案。114 年度主要產品營收為 LCD 顯示器新台幣 31,277 仟元、LCM 新台幣 1,939,195 仟元、其他新台幣 33,021 仟元,合計營業收入新台幣 2,003,493 仟元;換算 LCM 約占 96.79%,LCD 約占 1.56%,其他約占 1.65%,LCM 為絕對主力。公司商業模式以客製化顯示器與模組設計、製造、光學貼合、觸控整合與部分 OEM/JDM 整合服務為主,避開純標準品價格競爭,聚焦工控、醫療、白色家電、車載/船舶、戶外應用與儀器設備等利基市場。114 年法說會揭露 2025 年第三季地區營收比重為歐洲 67%、台灣 18%、香港及大陸 8%、日本 3%、美洲 3%、東南亞 1%;應用別為家電 58%、工業/儀器 34%、車用 3%、消費性 3%、通訊 1%、醫療 1%。主要客戶名稱年報未公開;公開報導指出 2025 年成長主因為歐洲家電客戶拉貨,工控產品接單穩定且毛利較佳。歷史產業資料曾提及車載中控與儀表相關客戶,但未由最新年報逐名確認。

Outlook 2025–2028

2025 年已反映歐洲家電客戶拉貨與產品升級效益,全年合併營收新台幣 20.03 億元,年增 28.8%,114 年營業淨利新台幣 131,392 仟元,較 113 年增加 43.1%;獲利成長亦受營收放大與所得稅利益影響。2026 年公司與媒體報導指出家電客戶接單透明度已看到 2026 年,工控/儀器產品接單維持穩定;公司預估 115 年 LCD 銷售量 709 仟個、LCM 銷售量 2,871 仟個,合計 3,580 仟個。資本支出重點為 1 至 7 吋自動化機台、AOI 液晶顯示屏線路檢驗、耐候性 UV 日照環測設備與 COG 機器,以提升效率、良率、檢測能力與耐候產品開發。2025 至 2028 年主要成長動能可歸納為:一、家電顯示模組尺寸升級與歐洲客戶需求;二、工控、醫療、儀器、車載與船舶等高客製化利基應用;三、光學貼合、觸控、系統板、NFC、光感測、震動回饋等整合型 HMI 模組;四、高耐候戶外顯示、低耗電反射式顯示、電子紙、Local Dimming Mini-LED、電濕潤顯示器 EWD、量子點自發光 QLED 等新技術。公司法說資料提到與策略夥伴開發 QLED,優勢為量子點材料自製、常溫簡化製程、無機材料穩定與較高色彩飽和度;EWD 則與荷蘭 Miortech 合作多年,10.1 吋疊構產品已開發完成,並朝 21.5 吋 IGZO TFT Array 基板方向開發。主要風險包含:最大銷貨客戶占銷貨總額 59.62% 的客戶集中風險、前五大客戶應收帳款占比 88% 的信用集中風險、歐洲家電拉貨若告一段落造成成長基期壓力、匯率波動與新台幣升值壓力、原物料與工資上升、TFT/觸控/中小尺寸面板競爭、EWD/QLED 等新技術量產時程與商業化不確定性、地緣政治與供應鏈重組、碳費/CBAM/ESG 揭露要求。2027 至 2028 年並無公司正式量化財測,以上為依年報研發計畫、法說技術路線與產業需求所做之方向性整理。

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.
