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 78+16.6% +12.4% 79.5% +16.8%

80-100 933-3.4% -9.7% 29.3% -22.5%

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 ≈ 18.33, at the 46.6th percentile of its own history (40-60 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.

Outlook 2025–2028

2025 年公司面臨美國關稅政策頻繁調整、中國輪胎產能過剩、海外貿易壁壘升高、成熟產品價格競爭與原物料及供應鏈波動,114 年營收與獲利均下滑,顯示產業競爭及毛利壓力仍大。公司 2026 年經營方向聚焦銷售與獲利成長、組織及管理制度合理化、技術與創新能力、集團全球化整合,並以品質、服務、信賴為核心。成長動能包含:電動車胎 VICTRA SPORT EV 與新世代環保稻殼白碳黑配方輪胎、PREMITRA HP6 與 VICTRA SPORT 6、符合 CNS1431 濕地抓地力/滾動阻力/噪音標準的次世代乘用車胎、卡丁車胎與越野賽事胎、自行車高階胎、OE 原廠配套與 OES 服務廠通路深化。公司揭露 115 年度預計合併銷售量 284,980 仟條,其中機車外胎 108,549 仟條、內胎 79,144 仟條、自行車外胎 51,233 仟條、輻射層汽車外胎 24,549 仟條、其他輪胎 17,835 仟條、輻射層卡車外胎 3,670 仟條。2026 至 2028 推估重點為全球在地化生產、印尼/印度/泰國/越南等海外布局、台灣第三分廠與卡丁賽車胎產線效益、北美與歐洲 OE 滲透率、AM 市場市占維持、綠色材料與低碳胎升級。主要風險包含天然橡膠與合成橡膠價格波動、碳黑與鋼絲等原料成本、匯率、關稅與反傾銷、地緣政治、中國輪胎供過於求、全球車市需求不確定、成熟輪胎產品價格競爭、環保法規與碳排要求。2027 至 2028 的具體財務數字公司未公開,以上屬依公司年報與法說資料延伸之產業展望推估。

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.
