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 band | Sample days | 240-day avg return | Median | Win rate | Avg excess (vs index) |
|---|---|---|---|---|---|
| 0-20 | 745 | +0.7% | +1.9% | 52.2% | -10.9% |
| 20-40 | 343 | +8.4% | +3.4% | 67.6% | -1.7% |
| 40-60 | 144 | -7.7% | +1.4% | 53.5% | -22.8% |
| 60-80 | 154 | -11.5% | -13.6% | 15.6% | -23.7% |
| 80-100 You are here | 571 | -9.4% | -7.2% | 24% | -38.6% |
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 ≈ 56.8, at the 82.7th 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.
Currently in “Expensive (own-history top 1/3) × 60-day momentum down”: across 424 historical days, 120-day forward avg declined 4.3%, win rate 29.5%, lagged the market by 10.9%.
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
南六是垂直整合型不織布與衍生成品製造商,核心模式為以水針不織布、熱風/熱壓不織布、醫療衛材與生技保養品為基礎,提供原布、加工與成品代工,客戶多為國內外衛生用品、醫療、個人清潔與美妝品牌。依2025股東會年報所揭露的2024年度營收結構,熱風不織布約新台幣20.77億元、占30.93%;生技產品約19.28億元、占28.71%,包含柔濕巾、面膜、保養品等;水針不織布約18.71億元、占27.86%;水針後處理線約8.28億元、占12.32%;口罩約0.12億元、占0.18%;合計約67.16億元。產品應用包含嬰兒與成人紙尿褲及衛生棉表面材、口罩材料、醫療級手術防護衣與隔離衣用布、醫療鋪單布、無塵電子擦拭布、清潔擦拭布、藥膏用布、濕紙巾、面膜、卸妝棉與保養品。公司官網與永續報告書提到曾為花王、金百利、幫寶適等國際品牌代工;年報則因商業機密將主要客戶匿名為戊公司、己公司、丙公司等,2024年兩大客戶各占銷貨淨額約11.96%與11.93%。主要原料為PP纖維、複合棉、嫘縈棉、PET棉與不織布,2024年主要供應商中賽得利占進貨淨額15.09%。
Outlook 2025–2028
2025至2028年展望可分為成長動能與風險兩面。成長動能方面,第一,印度廠是最明確的中期引擎:公司年報指出印度廠已運行順暢、訂單穩定成長,並深耕印度及開拓中東、非洲市場;2026年5月公司公告董事會決議對印度孫公司NANLIU MANUFACTURING (INDIA) PVT. LTD.增資,交易總金額為INR 1,160,000仟元,顯示印度產能與營運資金配置仍在擴張。第二,產品組合往高附加價值發展,包括醫療用木漿水針複合不織布、可分解複合不織布、彈性複合不織布、醫療手術衣用布、高端無塵擦拭布、吸水材料及生技保養品;這有助於降低低價標準品競爭壓力。第三,台灣燕巢廠遷移後,濕巾、面膜與不織布產線完成安裝並量產,可支撐效率與產能改善。第四,全球不織布仍具衛生、醫療、個人清潔、電子無塵擦拭與環保材料需求,尤其印度人口紅利、紙尿褲與濕巾滲透率提升可支撐當地市場。第三方法說整理資料指出,2025年前三季合併營收約49.06億元,印度廠營收成長率預期超過40%,且動能可延續至2026與2027年;另稱中國平湖廠爭取到韓國醫療客戶及加拿大P&G新增訂單,但此部分非公司年報逐字揭露,屬較低可驗證度資訊。風險方面,年報明確指出疫情後中國新增過多不織布產線造成同業競爭劇烈,台灣外銷鄰近國家市場縮減、產能利用率下降;原物料、能源、人工及物流成本上升,售價未必能完全轉嫁;匯率波動、印度投資與跨國管理、客戶集中、環保法規、一次性產品減塑與可分解材料要求,均可能影響毛利與資本支出回收。2028以前若印度擴產去化順利、醫療與高階材料占比提高,營收品質有機會改善;若低價競爭與成本壓力持續,獲利彈性仍受限制。
