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)
0-20 449+9.2% +5% 59% +1.9%

80-100 You are here746+23.9% +19.9% 73.3% +8.9%

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 ≈ 19.78, at the 87.9th percentile of its own history (80-100 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 菱光 do? Company profile

電子零組件業;接觸式影像感測模組 CISM/影像感測器 台灣證券交易所上市

Overview

8249 對應證券為菱光科技股份有限公司,普通股,股票簡稱菱光,英文簡稱 CSI,為台灣證券交易所上市公司,產業別為電子零組件業。公司成立於 1998 年 6 月 15 日,總部位於台北市內湖區南京東路六段501號9樓,2005 年 5 月集中交易市場掛牌上市。董事長為黃育仁,總經理暨發言人為魏耀明,簽證會計師事務所為資誠聯合會計師事務所,股務代理為元大證券股務代理部。依公司 113 年股東會年報,2024 年完成現金減資後,2025 年 3 月 22 日普通股已發行股數為 134,149,500 股,額定股本 25 億元,已發行資本額約新台幣 13.41495 億元;其中上市股票 114,349,500 股、私募股票 19,800,000 股。員工規模方面,年報揭露本集團 2024 年員工 1,060 人、2025 年 3 月 31 日為 1,001 人。主要股東依 2025 年 3 月 22 日年報揭露為:東友科技 19.39%、環球水泥 8.83%、天達投資 8.28%、環泥投資 6.04%、光菱電子 3.82%、菱光科技庫藏或自有持股 3.38%、林高煌 1.56%、侯阿忠 1.29%、賴和貴 0.75%、劉榮煌 0.57%。公司為東元集團相關轉投資體系,並持有東友科技、天達投資等權益法投資。

Business

菱光核心業務為 CISM(Contact Image Sensor Module,接觸式影像感測模組)之設計、製造與買賣。依 113 年股東會年報,2023 年與 2024 年營收項目皆為影像感測器 100%,2024 年營業收入新台幣 42.00192 億元,年增 37.4%,毛利 8.58386 億元,EPS 3.27 元。主要產品應用於多功能事務機 MFP、掃描器、傳真機、影印機、電子白板、指紋辨識、紙鈔辨識、支票與名片掃描等文件影像輸入設備。商業模式以關鍵零組件與模組設計製造為主,購入晶圓、柱狀透鏡、導光板、塑膠機殼與其他電子零件後,經晶圓測試、切割、上片、打線、組立、測試檢驗後,銷售給國際品牌客戶、系統廠或專業製造代工廠。公司官網另揭露產品線包括線性感測模組、隱形雷射晶圓切割服務與 LWIR 紅外熱成像產品;紅外熱成像機芯產品可應用於安全監控、無人機、智慧交通、溫度檢測、國防安全等領域。年報揭露 2024 年前四大客戶以甲、乙、丙、丁公司匿名列示,營收占比分別為 14.66%、12.51%、10.56%、9.80%,客戶集中度高且以國際大廠為主;公司官網沿革曾列示獲 Brother、Epson、HP、Samsung 等供應商獎項,顯示其歷史下游客戶或合作關係集中於國際列印與事務機品牌。

Outlook 2025–2028

2025 至 2028 年展望可分為成熟本業與新產品滲透兩條線。成熟本業方面,CISM 在 MFP 與掃描輸入設備中仍為主流元件,公司在彩色接觸式影像感測器具規模、成本與品質優勢;但年報亦明確指出,多功能事務機市場已成熟,長期受無紙化與生成式 AI 影響,出貨量預估逐年微幅下調,消費型機種需求偏弱,商用機種則因新機種開發與彩色列印需求而相對持穩。因此 2025-2028 年本業主要動能在高階 A3/A4 CISM、高景深、高速、高解析、低功耗、輕薄短小模組與新世代高亮度 CISM 光源,以及提高自動化與關鍵零組件自製率以維持毛利。新產品方面,公司 2025 年經營方針包括第二生產基地規劃、提升自動化比重、導入關鍵零組件自製、完成 Smart Pattern Sensor 少量出貨並爭取品牌 ODM 代工、開發新一代紅外線成像與測溫機芯並導入 AI 影像處理。2026 年媒體與法說資訊顯示,IR 產品線已進入小量出貨與驗證階段,應用聚焦無人機、安防監控、機器人、海事、商用紅外線檢測、工業檢測與可能的國防安全需求,因專案導入期較長,短期營收貢獻仍需觀察,但若通過客戶驗證並放量,2026-2028 年有機會降低對 MFP 單一市場的依賴。主要風險包括:MFP 長期量縮、產品營收仍高度集中於影像感測器、前四大客戶占比高、上游部分原料或零組件寡占造成議價彈性小、價格競爭、美元與新台幣匯率波動、美國關稅與地緣政治導致客戶拉貨或庫存調整、第二生產基地投資與爬坡進度不確定、IR/SPS 新產品驗證期長且量產時點與毛利貢獻尚未充分公開。

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.
