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)
0-20 647+5.9% -6.5% 46.7% -9.3%
20-40 280+23.8% +10.3% 63.2% +0.7%
40-60 246+37% +35.2% 85% +14.7%
60-80 320+12.7% +4% 53.4% -3.4%
80-100 You are here465+22.6% +7% 61.1% -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 ≈ 80.42, at the 93.8th 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.

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

南茂為專業 IC 後段封裝測試服務公司,商業模式為替無晶圓 IC 設計公司、整合元件製造商(IDM)與晶圓代工廠提供委外封裝、測試、晶圓凸塊與相關 turnkey / end-to-end 服務。主要產品與服務包括高密度記憶體 IC 封裝測試、顯示器驅動 IC 封裝測試(含金凸塊、COF、COG、COP 等)、邏輯/混合訊號 IC 封裝測試、晶圓凸塊製造、WLCSP 與 Flip Chip 等。2024 年報說明公司產品主要應用於電腦、消費性電子儲存設備、顯示器、通訊設備、辦公室自動化、車用與工業應用等。2024 年營收地區結構為內銷 79.66%、亞洲外銷 17.94%、美洲 2.16%、其他 0.24%,合併營收新台幣 226.96 億元,約占台灣 IC 封測產值 3.6%。2025 全年營收新台幣 239.33 億元,年增 5.5%;2026 第一季營收新台幣 69.36 億元,季增 6.4%、年增 25.4%,EPS 0.72 元;2026 年 5 月單月營收新台幣 23.84 億元、年增 17.72%,2026 年前 5 月累計營收新台幣 117.80 億元、年增 25.08%。產品別最新公開資料非公司完整年度分項揭露;2025 第三季媒體依公司法說整理指出記憶體占比約 48.9%,DDIC 與金凸塊約 41.4%,其餘為混合訊號與其他。公司 2024 年報揭露 2024 年主要銷貨客戶以匿名方式列示:客戶 A 占 23.69%、客戶 B 占 11.47%、客戶 K 占 10.96%、其他占 53.88%。

Outlook 2025–2028

2025 至 2026 年營運重點由記憶體需求復甦與 AI/資料中心相關高價值記憶體封測需求帶動。公司 2025 全年營收年增 5.5%,2026 第一季營收年增 25.4%,公司於 2026 第一季新聞稿指出,AI 相關應用、資料中心市場、需求供給失衡、高價值記憶體方案與產能受限環境,支撐成長、價格與稼動率。2026 年 2 月法說相關報導指出,董事長鄭世杰表示 2026 年整體營運動能優於 2025 年,特別看好記憶體;第一季已再度調漲記憶體封測報價,新增記憶體相關資本支出,且新增產能已與客戶簽訂三年保障合約。資本支出方向以記憶體測試為主,並配置於封裝、驅動 IC 與金凸塊、混合訊號;公司亦布局 DDR5、DDR6、高頻記憶體、AI 應用 ASIC、MiniLED、日本邊緣裝置 IC、AMOLED、車載驅動 IC、MEMS 與低成本凸塊/封裝解決方案。2024 年報技術計畫包含 DDR5 DRAM 封裝、具散熱片 Flip-chip BGA、銀合金凸塊於顯示驅動 IC、記憶體 1M1P RDL、Micro-LED TV 雙層 COF 雙晶片、COF 非矩形金凸塊、覆晶與打線混合鍵合、具散熱片 Flip-chip CSP 等。2025-2028 展望可歸納為:一、AI 伺服器、資料中心與企業級 SSD/DDR5 帶動記憶體測試與封裝需求;二、車用面板、穿戴式、OLED、AMOLED 與高階 DDIC 支撐顯示驅動業務,但消費性電子復甦節奏仍不確定;三、混合訊號與邏輯產品可分散產品組合風險;四、先進封裝、RDL、WLCSP、Flip Chip、COF/COP/COG 與散熱封裝技術提升附加價值。主要風險包括記憶體循環反轉、DDIC 消費需求疲弱、中國封測低價競爭、客戶集中度高、主要客戶匿名且占比高、黃金/基板/金線/樹脂等材料成本上漲、匯率波動、人才短缺、關稅與地緣政治變動、資本支出若需求不如預期造成稼動率壓力。

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.
