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 | 597 | +21.7% | +19% | 99.3% | +5.6% |
| 20-40 | 364 | +11.8% | +6.3% | 70.9% | -6.5% |
| 40-60 | 445 | +12.3% | +4.3% | 68.1% | -3.4% |
| 60-80 | 454 | +3.8% | +2.2% | 62.3% | -7.7% |
| 80-100 You are here | 1170 | +9.6% | +3.9% | 65.4% | -8.6% |
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 ≈ 382.5, at the 99.7th 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 down”: across 551 historical days, 120-day forward avg gained 0.6%, win rate 49%, lagged the market by 15.3%.
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
居易是台灣少數以自有品牌銷售全球的中小企業/SOHO 網通設備商,主要產品包含寬頻路由器、xDSL路由器、4G/5G Cellular 路由器、VPN/防火牆路由器、網路交換器、無線基地台、VoIP/IP PBX、VigorACS 等網管與集中控管軟體。商業模式以台灣研發、製造與品牌管理為核心,透過海外代理商、區域通路、系統整合商與企業 IT 通路銷售,客戶多為中小企業、辦公室、分支機構、通訊服務與系統整合應用。2024 年財報顯示營業收入新台幣11.78472億元,其中網路通訊產品收入10.95197億元、其他收入0.83275億元,約為網路通訊產品93%、其他7%;地區別為歐洲9.97845億元、亞洲1.16585億元、其他地區0.64042億元,約為歐洲84.7%、亞洲9.9%、其他5.4%。2025年前三季法說摘要顯示產品線中路由器占84.6%,其中寬頻路由器37.9%、xDSL路由器28.5%、Cellular路由器18.2%;交換器6.5%、無線基地台5.1%、軟體2.3%、其他1.5%。公司收入認列主要在產品控制移轉至客戶時認列,收款條件通常為出貨後30至60天。
Outlook 2025–2028
2025年營運明顯承壓:公開營收資料顯示2025年1至11月累計營收約新台幣6.96078億元、年減37.49%;第三方轉載公開資訊顯示2025全年營收約7.572億元、EPS約0.60元,較2024年EPS 2.88元大幅下滑。至2026年5月,單月合併營收4,927.1萬元、年減21.11%,1至5月累計營收2.37670億元、年減33.10%,顯示短期需求仍未回到2024高峰。中長期成長動能主要來自企業網路頻寬升級、Wi-Fi 6/Wi-Fi 7、2.5G/10G交換器、VPN/防火牆與資安需求、分支辦公與遠端管理、4G/5G備援或行動路由、光纖寬頻/GPON/XGS-PON 相關需求,以及 VigorACS 等軟體與雲端化管理帶來的附加價值。公司在歐洲品牌與中小企業市場具基礎,若歐洲通路庫存去化完成、Cellular路由器與新一代高速產品放量,2026至2028可能逐步修復營收與毛利結構。主要風險包括:歐洲營收占比過高導致區域景氣、匯率與通路庫存風險集中;網通產品生命週期短、價格競爭激烈,財報亦將存貨跌價列為重要查核事項;大型國際品牌與低價中國品牌競爭;晶片、記憶體與PCB等零組件成本波動;資安漏洞或產品品質事件對品牌信任的影響;以及公司規模較小,研發與行銷資源相對 Cisco、Ubiquiti、Netgear、D-Link、Zyxel 等品牌有限。2027至2028展望屬推估,缺乏公司正式財測,需追蹤月營收是否止跌、歐洲通路拉貨、Wi-Fi 7/5G/高速交換器產品比重、毛利率與存貨水位。

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.
