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)
0-20 276+26.9% +30.2% 81.2% +7.3%
20-40 293+18.2% +18.7% 73% +2%

80-100 You are here850+14.7% +12.7% 77.1% +2.7%

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 ≈ 35.94, at the 97.7th 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.

Business

通泰定位為專業消費性應用IC設計公司,商業模式以IC設計、委託晶圓代工與封裝測試、再銷售積體電路、晶粒與晶圓為主;公司內部以研發設計、晶圓測試、封裝品測試與出貨包裝為主,晶圓生產與封裝作業委託國內外合格廠商製作。2024年度依產品型態分,積體電路營收約57.87%、晶粒26.22%、晶圓15.91%、設計收入接近0%。依產品系列分,觸摸系列約60.01%、健康醫療系列約21.59%、3C家電及週邊系列約9.27%、綠色節能系列約4.92%、影音多媒體系列約4.21%。2025年度依年報摘要,電容式觸摸系列約55.4%、健康醫療系列約25.9%、3C家電及週邊應用系列約10.5%、影音多媒體系列約5.5%、綠色節能減碳系列約2.7%。主要產品包括電容式觸控MCU、TTP系列觸控IC、體溫計IC、心率偵測、室內外溫度計、PIR人體感測控制IC、LED照明控制、計算機MCU、LCD Type MCU、IO Type MCU、A/D Type MCU、LCD Game/TV Game周邊與語音合成IC等。主要終端應用涵蓋家電觸控、燈控開關、檯燈、電視、電話、微波爐、電子秤、體重計、計算機、DVD音響、筆電多媒體鍵、液晶顯示器、滑鼠鍵盤、USB喇叭、GPS、數位相框、兒童玩具、手機周邊、工業控制開關、POS、門禁鎖、保險箱、汽車電子控制、醫療儀器、電表、電梯、安全監控、體溫計、人體感測燈與LED照明。銷售區域高度集中於中國大陸,2024年度中國大陸銷售約94.62%、台灣約5.38%;主要客戶於年報以甲、乙、丙等代號揭露,未公開公司名稱。

Outlook 2025–2028

2025至2028年展望以利基型消費性IC、MCU與觸控感測產品更新為核心。短期動能包括公司持續推廣新觸控IC及模組、耐水觸控系列、電容感測系列,以及利用晶圓廠新製程開發更快速、更節能、更具性價比的新產品。公司年報指出,2024年成長部分受惠於客戶消化疫情期間庫存後恢復拉貨,以及美國可能調升對中國進口關稅前的提前備貨;2025年則因前期拉貨後客戶庫存消化,營收較2024年衰退。展望2026年,公司預期新產品加入銷售、客戶提前備庫及新應用推廣有助需求恢復。中長期而言,AI、高效能運算與車用半導體雖非通泰主戰場,但整體半導體景氣回溫、AioT、智慧家電、健康量測、工業控制、陪伴型玩具與人機互動介面增加,可能帶動低功耗MCU、觸控、感測與醫療量測IC需求。主要風險包括中國成熟製程產能過剩造成低價競爭、消費性電子需求波動、客戶與區域集中度高、中國大陸銷售比重過高、美元匯率與關稅政策不確定、晶圓代工與封測供應成本、產品單價壓力、研發資源相對大型IC設計業者有限,以及主要客戶未公開使投資人難以評估客戶品質與終端需求。2025至2028年的具體營收或獲利數字公司未提供明確財測,本文不做量化推估。

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.
