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.

Current PE ≈ 16.26, at the 15.3th percentile of its own history (0-20 band).

Outlook 2025–2028

2025至2028年展望以公司已揭露策略及產業趨勢推估,未使用未公告財測。2025年短期動能包括:2024年國內生理食鹽水短缺帶動大型輸注液增產,年報明載該部分成長估計仍會帶動2025年營收;2025年公司計畫大型注射劑13,532,594瓶/袋、小型注射劑24,045,803瓶/支、粉末注射劑13,351,598瓶、錠劑247,103,249錠等銷售量。海外方面,美國Linezolid市占提升、日本Ibandronate與Palonosetron預充填注射劑、中國Methylprednisolone一致性評價及集採標案,均為外銷與國際化重點。產品策略聚焦Ready-to-use預充式注射劑、預混式輸注液、抗癌針劑、505(b)(2)類新藥、長效控釋針劑、營養/預防醫學輸注液與生物製劑CMO。2026至2028年潛在動能來自研發管線:年報列示ND-553抗癌藥物預計2026/Q2、ND-554血液用藥預計2026/Q4,ND-483、ND-560、ND-568、ND-569、ND-571、ND-572~574、ND-575、ND-581等多項處方或製程設備評估中項目預計2027/Q4,但這些時程屬研發計畫,實際量產仍受查驗登記、臨床、BE試驗、製程放大與法規審查影響。公司並於2025年啟用南港國際營運總部,宣布跨足預防醫學,與優點診所/預防醫學中心合作,目標建立診所模式後再展店,若能形成自費醫療與營養輸注液協同,可能分散健保藥價壓力。中長期產業趨勢有利因素包括高齡化、急重症醫療與護理人力壓力推升即用型藥物需求、醫院對Non-PVC/PP軟袋與用藥安全辨識需求提升、學名藥國際市場與日本/美國高品質製劑需求。不利因素及風險包括健保藥價調降、國內外學名藥價格競爭、中國集採壓價、FDA/PMDA/GMP查廠與法規風險、研發與臨床失敗、海外合作夥伴銷售不如預期、PP軟袋包材單一供應商依賴、匯率與原料藥/包材成本波動、預防醫學新事業展店與營運模式仍需驗證。

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.
