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)
0-20 879+5.3% +2.4% 58.9% -8.6%
20-40 439-13.4% -16% 8.7% -24.6%

80-100 251+38.6% +40.6% 85.3% +25.1%

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 ≈ 17.06, at the 68.5th 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.

Business

億光為LED與光電半導體元件製造商,主要產品為發光元件與感測元件,官網列示主要應用包括LED照明、LED背光、顯示屏、手機、車用、消費性電子產品等。公司產品線涵蓋可見光LED、紅外線產品、感測器、光耦元件、功率半導體,並延伸至車用LED、Mini LED、UV LED、植物照明、光耦合器、VCSEL、光編碼器、SiC/GaN/SJ MOS等。2025年年報之114年度銷售淨額為新台幣19,639,955仟元,產品別為LED 18,492,944仟元、占94.16%;照明1,051,865仟元、占5.36%;其他95,146仟元、占0.48%;LCD為0。區域別為亞洲17,539,412仟元、占89.30%;歐洲1,380,255仟元、占7.03%;美洲511,912仟元、占2.61%;其他208,376仟元、占1.06%。2025年上半年法說會相關報導指出2025Q1產品組合約為不可見光40%、消費型電子及手機23%、背光15%、車用14%、照明8%、其他1%;其中不可見光主要為光耦合器與感測元件,光耦占不可見光比重約50%。商業模式以研發、製造與銷售LED封裝元件、模組與感測/隔離元件為核心,服務手機、NB、PC、TV、家電、網通、伺服器、汽車內外照明、車載背光、智慧眼鏡、穿戴裝置、工控、充電樁、儲能、AIoT與智慧城市等終端應用。2025年年報揭露最近二年度無單一銷貨客戶占銷貨總額10%以上。

Outlook 2025–2028

2025年實績方面,公司2025年合併營收約新台幣196.4億元,較2024年衰退6.4%,但因產品組合優化與成本控制,毛利率提升至31%,營業淨利約24.6億元,歸屬母公司淨利約20.4億元,EPS 4.60元;2025年每股擬配發現金合計4.5元。2026年公司在年報致股東報告中明確表示不可見光與車用領域仍是發展重點;AI帶動工業自動化、機器手臂、協作機器人、人形機器人需求,將增加感測元件與光耦產品在偵測與控制模組的應用;智慧眼鏡出貨預估成長亦可能帶動感測元件需求。車用方面,公司著重提高市占率,已針對頭燈市場推出產品並獲客戶採用,Smart LED氣氛燈、Mini LED背光模組、車用頭燈、尾燈、格柵燈、UVC殺菌模組等為推廣方向。產業面,年報引用OMDIA估計全球LED市場產值由2024年161億美元成長至2030年188億美元,2023至2029年複合成長率3.0%,車用市場至2030年複合成長率6.2%,車用營收可望達49億美元。2026至2028年推估成長動能主要來自不可見光光耦與感測、車用LED與車載背光、工控/儲能/充電樁、AI伺服器電源控制、智慧眼鏡與穿戴式裝置、Mini/Micro LED及功率元件。風險與挑戰包括全球關稅與地緣政治、匯率波動、金屬原物料如金、銅、錫上漲造成成本壓力、LED成熟產品價格競爭、照明與背光等低毛利產品壓力、供應鏈重組與非中非台產能需求、泰國產能進度受關稅不確定性影響,以及車市成長若僅持平則車用業務須仰賴市占率提升。2027至2028年未見公司提供明確財務預測,因此僅能以公司公開的3至5年產品開發方向與產業趨勢作為推估。

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.
