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 band | Sample days | 240-day avg return | Median | Win rate | Avg excess (vs index) |
|---|---|---|---|---|---|
| 0-20 | 436 | -1.9% | -8.1% | 24.3% | -18.7% |
| 20-40 | 267 | +36.3% | +38.3% | 75.3% | +5.4% |
| 40-60 | 178 | +31.3% | +28.2% | 91.6% | +8.9% |
| 60-80 | 62 | -12.5% | -11.3% | 3.2% | -19.9% |
| 80-100 You are here | 297 | +43.7% | -2.1% | 44.4% | +9.9% |
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 ≈ 134.17, at the 93.3th 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.
Currently in “Expensive (own-history top 1/3) × 60-day momentum up”: across 222 historical days, 120-day forward avg gained 28.5%, win rate 55%, beat the market by 4%.
Days = trading days in this bucket; returns use adjusted prices, ex-costs. 60-day momentum: direction of this stock's price over the past 60 trading days.

Business
公司為營運型普通股,主要業務為印刷電路板製造銷售與光電移動照明產品。2025年合併營收為新台幣1,082,478仟元,年增9.81%;稅後淨利4,736仟元,年減14.79%。2025年產品營收結構為:多層印刷電路板786,824仟元、占73%;雙層印刷電路板83,852仟元、占8%;移動照明174,447仟元、占16%;其他34,797仟元、占3%;散熱鋁基板2,558仟元、占比約0%。PCB事業處主要產品為2至16層印刷電路板,並提升HDI盲埋孔、4oz厚銅、散熱鋁基板與高層數產品比重,應用於個人電腦、電腦週邊、衛星導航、網路通訊、醫療、電源供應器、工業電腦、LED TV、應用照明、汽車用途等。光電事業處主要產品為LED自行車燈、E-bike產品與相關燈組,採自有品牌DOSUN及OEM/ODM模式。2025年銷售地區為內銷75%、亞洲9%、歐洲3%、美洲13%;公司揭露個別銷售對象營業額均低於20%,但自行車燈業務因仍屬開發成長階段,客群集中度相對偏高。
Outlook 2025–2028
2025年公司營運重心為轉型變革、光電產品穩健成長與少量多樣利基產品,聚焦電動輔助自行車、行動照明、新材料開發、IPC工業電腦與高層別客戶。2026年公司年報指出AI與半導體需求重塑PCB產業,AI伺服器、高速運算、雲端平台、800G網通交換器、低軌衛星、工業與醫療等應用提高對高頻、高功耗、高密度板件需求;邑昇PCB端朝高縱橫比細線製程、高層高密度厚板、陶瓷板、高頻材料、電力板、HDI高密度產品、HLC高層數產品、3.6至4.2mm厚板、Server類、網路通訊、低軌衛星、雷達收發與無人機應用開發。光電端朝LED移動高照明車燈、快拆扣具、貨架燈、E-bike電動開關控制、智能儀表板、自行車方向燈、無線遙控方向燈、雷達尾燈與E-bike整合燈具發展,並規劃建置E-bike組裝線與調整PCB自動化產線。2027至2028年展望屬研究推估:若AI伺服器、工控、網通、低軌衛星、車用電子與E-bike需求延續,公司有機會受惠產品組合往高層數、高頻、厚銅、HDI與智慧車燈升級;主要挑戰包括規模較小、市占率低、上游銅箔、玻纖布、CCL、鑽針與化學材料漲價,台灣與中國大陸PCB同業競爭、環保法規成本、客戶庫存循環、自行車產業復甦不均、關稅與地緣政治造成供應鏈調整,以及高階製程投資能否轉化為穩定毛利。

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.
