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.

80-100 You are here371+6.3% +4.1% 64.4% -24.1%

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 ≈ 252.14, at the 95.6th percentile of its own history (80-100 band).

Valuation × momentum historical grid

Business

艾笛森定位為 LED 元件、模組與成品的光電製造服務廠,從 LED 封裝與模組延伸到照明、車用與傳感器應用。2024 年合併營收新台幣 25.59 億元,其中 LED 照明產品 12.96 億元、占 50.66%;LED 車用產品 11.13 億元、占 43.49%;傳感器元件 1.22 億元、占 4.78%;其他 1.07%。2025 年營收依 MoneyDJ 報導為 23.08 億元、年減 9.8%,歸屬母公司淨損 4,723.7 萬元、EPS -0.34 元。公司商業模式由傳統 LED 元件供應,轉向 LDMS(Lighting Design Manufacturing Service)全方位 LED 照明整合服務,協助客戶處理熱、電、機、光等設計問題,並提高模組與成品比重。主要產品包括高功率 LED、PLCC 元件、商業照明模組、智慧照明、路燈與戶外照明、車用頭燈/霧燈/晝行燈/尾燈/方向燈相關元件與模組、HUD LED、紅外線與 ToF/DTOF/ITR 等感測元件。下游客戶以 LED 照明應用製造商或代理商、LED 車用照明廠、光傳輸元件製造商為主;年報揭露 2024 年有一名代號 A4003 的 LED 車用 Tier 1 客戶占銷貨 15.52%,但未揭露實名。近期法說資訊顯示車用業務以 OEM 市場為主,模組與成品主要對接北美美系車廠,元件產品對應中國大陸當地電動車市場。

Outlook 2025–2028

2025 年:公司年報規劃持續由 LED 元件走向客製化模組與成品,擴大植物照明、醫療照明、智慧照明、商用照明及車用照明;2025 年原先看好二次替換需求支撐照明市場、車用照明受新能源車與先進車燈技術推升。不過實際 2025 年受新台幣升值、照明客戶保守與產品組合壓力影響,全年營收 23.08 億元、由盈轉虧。2026 年:公司近期法說與媒體報導顯示,管理層目標為出貨量年增約 10%至 20%,車用與感測元件動能優於照明;2026Q1 已轉盈,全年力拚不低於 2025 並朝轉盈。中壢新廠/廠辦規劃承接偏照明類、體積較大的成品生產,並整合外租產線與倉儲;車用產線集中中和,以降低租賃成本與提升產能配置效率。車用產品 Q4 2025 營收占比已過半,車用模組與成品為主要支撐;北美客戶訂單維持穩定,美系客戶霧燈產品由台灣生產,關稅影響相對有限。傳感器元件方面,公司布局 ITR、DTOF、紅外感測,應用瞄準掃地機器人、無人機、無人車、醫療/監控與工業感測,內部期待比重由約 5%提升至 8%至 10%或約 10%。2027 至 2028 年:公開資料未見公司正式財測;合理推估成長關鍵在車用 OEM/Tier 1 認證訂單放量、北美與中國電動車市場滲透、照明二次替換與 ESG 節能照明需求、智慧照明與感測應用擴張。主要風險包括 LED 產業價格競爭與產能過剩、照明需求復甦不均、匯率波動、車用客戶集中、車規認證週期長、關稅與地緣政治、專利侵權風險、原物料與 IC/PCB/螢光粉等供應成本波動,以及中壢新廠投產進度與產能利用率不如預期。

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.
