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 | 128 | +16.4% | +16.3% | 99.2% | +10.8% |
| 20-40 | 2 | Insufficient data | |||
| 40-60 | 23 | Insufficient data | |||
| 60-80 You are here | 44 | -5.5% | -5.9% | 15.9% | -9.5% |
| 80-100 | 3 | Insufficient data | |||
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 ≈ 63.5, at the 63.7th 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.

Outlook 2025–2028
2025 至 2028 年展望:公司 2025 年營收較 2024 年回升,但仍處虧損,顯示需求復甦與產品轉型尚未完全轉化為獲利。成長動能來自 Wi-Fi 7/未來 Wi-Fi 8 升級、5G FWA、企業專網、O-RAN、Small Cell、低軌衛星/NTN、AI/ML 帶動高速低延遲連線需求、工業物聯網、智慧能源 AMI、半導體設備 RFID/eRACK、無人載具與關鍵任務通訊。公司 2025 法說會指出,2023 至 2025 研發投資逐步轉化為營收,策略上深耕美、日、歐系品牌寬頻通訊客戶,擴大海外市場,並從射頻無線核心延伸到物聯網通訊模組、RAN 小基站、毫米波雷達、工規 FWA 裝置與整合無線解決方案。2026 成長動能包括寬頻基礎建設與衛星聯網、歐美營運商擴大 5G 與衛星聯網部署、半導體設備 RFID/eRACK 正式出貨並獲國內外封測大廠裝機採用,以及雷達感測與城市安全/無人機反制相關專案,部分專案預計 2026 年第二季進入商轉。2027 至 2028 年的中期機會,主要是 B5G、Wi-Fi 8、NTN、FWA、企業專網與智慧能源/工業物聯網應用擴大,帶動高頻寬、多頻段射頻通訊設備與高可靠度天線需求。風險與挑戰包括:全球通訊設備資本支出仍偏審慎、5G 終端需求復甦速度溫和、OEM/ODM 市場價格競爭加劇、中國供應鏈具規模與成本優勢、客戶對品質/成本/交期/系統整合能力要求提高、匯率波動、上下游供應鏈不確定性、產品轉型與新專案量產時程不確定、毛利率壓力與持續虧損風險,以及碳盤查與綠色供應鏈法規要求提高。

- 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.
