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)
0-20 437+23.8% +20% 71.6% -8.8%

80-100 You are here94+80.7% +102.8% 69.1% +62.1%

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 ≈ 61.81, at the 82.5th percentile of its own history (80-100 band).

Outlook 2025–2028

2025年:公司2025/05/20法說會指出,2025年第1季銷貨收入新台幣228,048千元、年增13%,毛利率22%優於2024年第1季18%,營業利益20,331千元、年增88%,稅後淨利19,114千元、EPS 0.68元;公司並表示透過產品銷售結構調整提升獲利,安全監控、醫療系列新產品及工業電腦產品接單與量產有助全年獲利。不過,2025年下半年營收轉弱,Yahoo股市月營收資料顯示2025年全年合併營收691,327千元,較2024年728,091千元下滑5.05%,顯示訂單、出貨時點或終端需求仍有波動。2026年:截至可得資料,2026年1月營收24,883千元、年減51.51%,2026年第1季EPS約0.08元,短期成長能見度低於2025年第1季高峰;但若新購廠房增建已按法說會規劃於2025年第4季啟用,後續產能、製程整合與醫療產品出貨放大將是觀察重點。2027至2028年:未找到公司公布的明確長期財測;推估成長動能包括AI網路攝影機、次世代CCTV類比高清攝影機、弱視專用擴視機、27吋手術用顯示器與23.8吋高對比超音波醫療顯示器等研發案,及安防影像升級、醫療影像數位化、特殊顯示器客製化與高毛利醫療顯示產品比重提升。主要風險包括匯率、關稅、歐美客戶需求與庫存調整、ODM/OEM客戶集中與議價壓力、LCD面板與IC等關鍵零組件價格波動、醫療產品認證與法規時程、規模較小導致營收波動放大,以及與大型安控、工控、醫療顯示廠商競爭。

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.
