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)

80-100 1055+7.9% +9.7% 84.6% -9.7%

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 ≈ 16.75, at the 30.4th percentile of its own history (20-40 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

公司為台北市核心區域公用天然氣事業,供應區域包含松山、信義、大安、萬華、中正、大同、中山等 7 行政區及士林區福華、明勝 2 里。主要業務為向台灣中油購買天然氣,降壓後透過管網配送給家庭、商業、服務業及公私機關團體用戶;同時經營瓦斯設備裝置工程、瓦斯器具與安全設備銷售安裝、瓦斯熱泵空調 GHP、資訊服務、通信電路出租及不動產租賃。114 年營收結構為:氣體收入 23.54720 億元、占 69.79%;裝置收入 6.46707 億元、占 19.17%;租賃收入 2.66294 億元、占 7.89%;通信收入 0.60001 億元、占 1.78%;器具收入 0.28606 億元、占 0.85%;勞務收入 0.17703 億元、占 0.52%。截至 114 年底供應區住戶數 600,830 戶,供氣使用戶 409,949 戶,區域普及率 68.23%;114 年應受檢戶發出 207,120 件通知,接受檢查 181,956 戶,定檢達成率 87.9%。主要客戶分散於一般家庭與商業用戶,年報明確揭露無單一銷貨客戶達銷貨總額 10%。商業模式具有特許區域、民生剛需與管線資產門檻,但瓦斯售價受主管機關管制,氣源高度集中於台灣中油。

Outlook 2025–2028

2025 年(民國 114 年)公司營收達 33.74031 億元,較公開月營收資料顯示的 2024 年 33.17860 億元小幅成長,核心獲利指標均達年度預算。2026 年(民國 115 年)公司年報揭露計畫目標為天然瓦斯銷售量 1.97 億度、增加用戶約 3,200 戶,並配合都更、危老重建、公共住宅、公有市場優化與商業活動復甦規劃管線。成長動能包括:既有區域補密與新建案接管、家用瓦斯型烘乾機與高效率熱水器推廣、微電腦瓦斯表普及率目標提升至 78.5%、老舊管線汰換 37,267 公尺、高壓管線 14,900 公尺緊密電位量測、GHP 瓦斯熱泵空調、汽電共生、燃料電池、瓦斯發電機、瓦斯乾衣機與安全器具。公司也把定位由傳統瓦斯公司延伸為乾淨能源供應商,導入 IFRS S1/S2、SCADA、3D 圖資、生成式 AI、智慧管網監測,並與國內固態氧化物燃料電池(SOFC)業者合作,瞄準醫療體系、頂級住宅與工業客戶的分散式能源與電力韌性需求。2027-2028 年公司未提供量化財測,合理展望仍以區域用戶緩慢成長、穩定民生用氣、低碳設備與分散式能源應用擴張為主。主要風險為:建案工期延後、人力與建材成本上升、天然氣價格與費率受政策管制、氣源集中於台灣中油、電磁爐與熱泵等替代品滲透、氣候暖化使部分用氣需求下降、碳費與減碳政策增加轉型壓力、資安與個資保護要求提升。

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.
