摘要


股票初次上市(櫃)所發行的公開說明書(Prospectus)不僅揭露企業之發展歷程、產業分析、企業規模、主要股東與董事會組成結構,以及歷年來營運與財務狀況,其中,最能吸引潛在投資人注目的,莫過於上市(櫃)當年度之財務預測。然而,企業本身的財務預測是否會受到營運風險或是市場風險所影響而導致財務預測可能產生偏誤現象,則有待進一步之驗證。本研究主要是針對台灣上櫃企業IPO公開說明書中所揭露的財務預測相關資料,利用線性模型加以檢視其是否存在所謂的偏誤現象。本研究經實證發現「財測期間」、「企業年齡」、「獲利穩定性」以及「IPO承銷新舊制」此四項變數對於台灣上櫃企業IPO公開說明書中之財測偏誤現象較具有顯著之解釋能力;且IPO當年度之「EPS」、「ROA」以及「ROE」亦較IPO前一年度的前述三項獲利指標具有較佳的解釋能力。就IPO上櫃後的短期報酬型態而言,經實證發現IPO當年度之「EPS」以及「IPO承銷之新舊制」具有較佳的解釋能力。彙總以上之實證結果,本研究發現「企業年齡」與IPO公開說明書中之財測偏誤程度具有正向關聯性,此結果與先前之研究具有相當的差異性;另一方面,「IPO承銷新舊制」不僅對於IPO公開說明書中之財測偏誤且IPO上櫃後的短期報酬型態亦具有顯著之解釋能力。
