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)
0-20 157+67.2% +63.9% 100% +47.3%
20-40 502+38.9% +21% 93.4% +25.2%

80-100 You are here926+9.7% +5.1% 56.5% -7.2%

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 ≈ 50.47, at the 99.9th 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.

Business

台半集團主要營業項目為整流器及條碼印表機之製造與買賣。依 2024 年報,2024 年合併營收新台幣 14,828,792 千元,其中整流器 6,030,732 千元、營收比重 40.67%,條碼印表機 8,798,060 千元、營收比重 59.33%;2024 年毛利率 29%,低於 2023 年 31%。功率半導體產品包含橋式整流器、快速恢復/高效率/超快恢復整流器、蕭特基整流器、高壓/低耗損/高操作溫度蕭特基、TVS 瞬態電壓抑制器、齊納二極體、車用功率二極體、碳化矽蕭特基、功率電晶體、MOSFET、Super-Junction MOSFET、車用 MOSFET、電源管理類比 IC、低壓差/超低壓差穩壓器、DC-DC 轉換器、LED 驅動 IC、車用 LED 驅動 IC、霍爾/磁性傳感器、ESD 保護、小訊號二極體與電晶體等。商業模式上,台半以自有品牌 TSC、產品設計、晶圓製造、封裝測試、全球銷售通路與技術服務為核心,並搭配晶圓代工、IC 設計與封裝代工合作。子公司鼎翰科技(3611)貢獻條碼印表機、自動識別列印機整機、標籤紙耗材、企業手持電腦與遠端印表機管理軟體等,屬 AIDC 自動識別解決方案。2026Q1 法說簡報揭露功率半導體應用結構中,汽車與工業合計約 70% 營收;2025 年上半年應用比重約汽車 56%、工業 15%、3C 24%、其他約 6%,區域則亞洲、歐美為主要市場。客戶名稱未完整公開;年報表示已與多家知名汽車大廠及電子公司建立長期合作關係,且近兩年度及 2025 年第 1 季無單一客戶銷貨占總營收 10% 以上,也無單一供應商進貨占 10% 以上。

Outlook 2025–2028

2025-2028 展望重點:一,汽車電子、工控、伺服器、資料中心與類比 IC 是核心成長軸。公司在年報與法說資料中反覆指出將持續布局車用電子、工控、伺服器與類比 IC,並推廣低阻抗 MOSFET、低損耗穩壓器、車用 LED 驅動 IC、車用 LDO、ESD 保護與高效能整流元件。二,功率元件升級趨勢有利於產品組合改善;電動車高壓化、48V 車用電力系統、ADAS/車身控制、再生能源、太陽能逆變器、儲能、UPS、伺服器電源、電信基地台等應用,推升 MOSFET、SiC、FRED、TVS、穩壓 IC 等需求。三,第三代半導體與高壓產品是研發主軸;公司已開發 650V/1200V SiC 蕭特基二極體技術平台,SiC MOSFET 仍在研發中,計畫開發碳化矽蕭特基/MOSFET 晶圓、車用/工業級 600V/800V/1200V/1600V 低損耗整流晶圓、1200V 快速恢復晶圓、次世代 Super Junction MOSFET 與 SGT MOSFET 晶圓。四,產能與垂直整合方面,年報列為長期計畫的是擴大自有晶圓生產能力、向上整合生產、導入自動化與新型封裝技術、提高產能與降低成本;利澤/宜蘭與山東/天津廠將支撐晶圓、封裝及全球供應。五,ESG 與客戶碳管理要求將成為競爭門檻;2024 永續報告書表示已啟動 ISO 14067 產品碳足跡導入,目標 2025 年完成並通過第三方查驗,2026 年持續完成主力產品碳足跡盤查。六,風險與挑戰包含全球景氣放緩、地緣政治、車用電子需求波動、終端與系統廠庫存調整、價格競爭、原物料與工資上漲、匯率與利率波動、客戶車規驗證週期長、SiC/GaN 研發與量產不確定性,以及國際大廠 Vishay、Nexperia、Infineon 等的規模與產品線競爭。2027-2028 的具體財務數字公司未公開,本段對 2027-2028 的描述屬基於公司長期發展計畫與產業趨勢的合理推估。

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.
