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.

PE percentile bandSample days240-day avg returnMedianWin rateAvg excess (vs index)
0-20 251+31.3% +15.2% 100% -15.8%
20-40 You are here202+18.7% +14.4% 80.2% -46.4%

60-80 127-11% -13.2% 24.4% -0.9%
80-100 182+0.9% 0% 50% -0.2%

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 ≈ 66.62, at the 29.5th percentile of its own history (20-40 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.

Business

冠西電主要業務為光電元件及繼電器元件之加工、裝配、製造及買賣,電子產品進出口貿易,裝飾燈製造買賣,再生能源與自用發電設備,以及土地開發。113年度營收1,107,072仟元,產品結構為裝飾燈事業部581,468仟元、占52.52%;光電477,106仟元、占43.10%;能源及材料貿易48,498仟元、占4.38%。光電產品包含光耦合器、光電繼電器、磁簧繼電器、固態繼電器等,應用於電源開關、充電器、家電、O/A設備、感測、控制器、工控自動化、電池管理系統、消費電子、通訊、醫療、電腦及周邊、安防監控、PLC與I/O控制板等。裝飾燈以LED節慶燈飾為主,主要市場為美洲、亞洲,終端多為歐美節慶裝飾、大型賣場、百貨、零售與網路通路。節淨蒸汽事業以棕櫚殼等生質燃料作為熱能與蒸汽應用。113年度銷售區域為台灣4.98%、亞洲其他地區43.94%、美洲51.08%,外銷合計95.02%。商業模式包括自有品牌銷售、OEM/代工、客製化設計與生產、子公司海外製造及銷售、印尼工業區開發與服務。

Outlook 2025–2028

2025至2028展望可分為四條主軸。第一,光電元件:公司年報與2025法說會均指出將持續開發高速光耦合、驅動光耦合器、輕薄短小元件、高階數位光耦合器、高CMTI與快速反應產品,布局工控自動化、AI、5G、車用電子、電動車、電池管理系統與充電樁等應用;公司亦表示投入車用電子領域、進行製程改善以提高毛利,並提高自有品牌市占率與爭取多元品牌代工。第二,產能與成本:公司規劃印尼生產據點降低成本,2025法說會指出印尼光電工廠於2025年第四季全製程投入生產;若順利放量,2026至2028有助分散中國/台灣產能、降低人工與關稅風險,但新廠良率、稼動率與客戶認證進度仍是關鍵。第三,裝飾燈:LED節慶燈飾滲透率提升、公司持續開發設計感較強及精緻戶外型聖誕燈飾,並在美國市場強化專利維權;但該事業高度依賴歐美消費景氣、節慶需求、庫存循環及主要客戶訂單。第四,新事業與AI/伺服器:2025法說會提出成立「AI算力事業部」,以光耦封裝技術升級至高速光纖模組並鎖定AI伺服器供應鏈;2026年2月公司代100%持股子公司 Cosmo Electronics (HK) Company Limited 公告與新加坡 NEVAX TECH PTE. LTD. 簽署伺服器銷售合約,期間115/02/08至118/02/08,總金額約8,160萬美元,已收部分訂金約816萬美元,但公司公告明示實際營收認列仍視後續履約,對本期損益尚無立即影響。主要風險包括:2025年全年營收947,295仟元、年減14.32%,2026年1至5月累計營收276,188仟元、年減25.2%,顯示既有業務仍承壓;光電元件面臨日系與歐美大廠競爭、非光隔離元件替代、產品迭代快速;裝飾燈面臨歐美消費與匯率波動;主要原料部分仰賴國外進口;印尼工業區與新產線需面對基礎建設、法規、土地開發、招商與執行風險。

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.
