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 | 190 | +25.9% | -19.2% | 28.4% | +2.3% |
| 20-40 | 168 | +0.5% | -9.8% | 41.1% | -33.2% |
| 40-60 | 635 | +8.7% | -1.7% | 49.3% | -7.5% |
| 60-80 | 710 | +81.5% | +9.2% | 57.7% | +73.8% |
| 80-100 You are here | 790 | +13.1% | -2.6% | 47% | +6.2% |
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 ≈ 75.58, at the 97.6th 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 422 historical days, 120-day forward avg gained 0.9%, win rate 49.3%, lagged the market by 3.3%.
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
西柏是專業影音 Pro AV 與多媒體影音處理方案供應商,營運模式包含自有品牌 CYP 與 ODM/JDM 設計製造服務。主要產品涵蓋數位影音處理器、HDMI/DVI/DisplayPort 規格轉換器、影像升降頻控制器、矩陣、切換器、分配器、延伸器、擷取器、HDBaseT 產品、AV over IP/HyLinX、Audio over IP、控制系統、EDID 模擬器、訊號產生器與分析儀、USB 延伸器、電源管理設備、醫療影像整合產品、3D醫療影像、強固型與船舶海事應用產品等。MoneyDJ資料指出2024年專業智慧型影音產品約占營收95%,其他維修、整流器、選台器等零件銷售約5%。公司銷售區域以海外為主,2024年銷售地區比重約美洲63%、亞洲18%、歐洲15%、台灣4%;主要客戶為北美地區專業智慧影音設備品牌商,官方新聞曾描述主要客戶為全球前五大影音設備品牌商。終端應用包括企業會議室、智慧教室、遠距教學、娛樂服務、電影院、賣場、電視牆、監控中心、控制中心、法院、政府機關、醫療院所檢驗室與手術房、醫療訓練中心、工業IoT、戰情中心、運動酒吧等。
Outlook 2025–2028
2025年至2028年展望以 AV over IP、醫療影像整合與高解析度專業影音控制為核心。2025年MoneyDJ報導指出,西柏主要客戶訂單較2024年回升,AV over IP產品占比約10%至20%,預期2025年提升至接近30%,且AV over IP屬新規格、毛利率較佳,產品組合改善有助毛利率;法人預期在客戶訂單回籠與產品組合優化下,2025年有機會轉虧為盈。2025年公司官網新聞顯示新推出4K60 4:4:4多視窗無縫切換矩陣,並以4K60影音控制中心解決方案獲2026台灣精品獎,顯示公司持續推進控制中心、會議空間、監控中心與任務關鍵影音整合應用。2026年公司官網資訊顯示,西柏持續參與InfoComm與ITEM等展會,醫療影像整合方案與Avalue Healthcare、CHIYI Technology等生態系夥伴合作,透過AV over IP將內視鏡、醫療影像設備與醫療顯示器整合至Medical Panel PC,並結合AI醫療輔助分析;公司亦引用全球醫療影像市場已逾600億美元、未來數年CAGR約4%至6%的產業趨勢。2027至2028年未查得公司公開量化財測或擴產計畫,合理觀察重點為:AV over IP取代傳統點對點影音佈線的滲透率、醫療影像解決方案量產與認證進度、自有品牌CYP能否提高毛利、北美Pro AV客戶庫存循環是否恢復、台灣生產基地在地緣政治與美中供應鏈重組下的接單機會。主要風險包括北美品牌客戶集中、終端Pro AV資本支出循環、醫療產品認證與導入期較長、匯率波動、IC與電源等關鍵零組件供應與成本、HDMI/HDBaseT/AV over IP技術標準更迭、國際大廠Crestron/Extron/AMX/Kramer競爭、營收規模偏小導致固定費用槓桿高,以及若新產品出貨不如預期則毛利率改善有限。

Method and limitations
- All returns use adjusted close (etl:adj_close), already adjusted for dividends and splits.

- 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.
