摘要


本研究以台灣證券交易所公開上市公司1995年1月1日至2006年12月31日止,共計12個完整營業年度資料為樣本,採用Miller and Modigliani(1996)與Ohlson(1995)所提出的評價模型為基礎,透過股價模型與報酬模型的分析方式探討股價與盈餘增長模式的關係,研究的焦點在檢視當公司擁有至少三年盈餘連續增長模式時,是否相對於其他的公司,能獲得市場上投資人給予較高的市價盈餘乘數,也代表著擁有盈餘增長模式公司之盈餘反應係數(ERC)將大於沒有盈餘增長模式的公司。此外,在考量投資人於訂價(Pricing)時會因公司的特性而在價格計算上給予適度調整(Discount or Premium),預期盈餘增長模式將與公司的特性具有相關性,如公司成長性及風險性,故將主要變數:盈餘、帳面價值、成長性及風險性,納入主要測試模式的考量中。 透過股價模型與報酬模型並以橫斷面(Cross Sectional)及分年度(Separately Year)兩種分析方式進行回歸估計後,實證結果發現發現,國內上市公司若擁有盈餘持續增長的模式,則相較於其他公司,市場能給予較高的價格對盈餘的乘數;但當公司盈餘脫離先前之持續增長模式而開始減少之後,其價格對盈餘的乘數亦會顯著下降或甚至消失。這些發現均指出,盈餘乘數會隨著盈餘模式的發展而變動,然而,盈餘乘數的變動並不是因為在盈餘模式發展之前,就已經知道的因素所導致,分析的結果並不排除公司獲得市場給予較高的盈餘乘數,可能是因為在盈餘模式被揭示之前,來自於其他市場投資人已知的因素,或與公司價值相關特質的可能性。但經由實證的結果是可以說明在一定的程度上盈餘乘數會隨著時間與盈餘模式的發展而改變的論點。總結來說,研究結果發現,公司在相同水準的成長規模下,擁有盈餘連續成長的公司相較於無法持續的公司,被賦予較高的市場價值。

This study based on valuation model by Miller and Modigliani (1996) and Ohlson (1995) and took all public companies traded in Taiwan Stock Exchange as samples from 1995 to 2006.Via analysis of price and return model, we like to discuss the relations between share price and pattern of increasing earnings . This study focus on whether firms with patterns of increasing earnings could enjoy higher price-earning multiples from investors, compared to other firms, when they had patterns of increasing earnings lasting three years or longer. That is, the firms with patterns of increasing earnings have higher earnings response coefficients than the ones without that. Besides that, taking into consideration that investors will price firms with premium or discount because of specific characteristics of different firms, we also expect that patterns of increasing earnings are associated with firm characteristics such as growth and risk. According to prior research finds (see, Barth, Elliot, & Finn,1999), we used proxies for growth and risk into the regression estimation. Both price and return model, we find that market can accept higher price-earning multiples when the firms had at least three consecutive years of increasing earnings. But the price-earning multiples will be decreasing even diminishing when the firms were out of previously increasing model and began decreasing. These findings all pointed out the price-earning multiples will change with earning developments accordingly. However, the conclusion from this analysis can not exclude the possibilities of known variables from investors before disclosure of earning model or the specific characteristics of companies’ value. But the empirical conclusion can explain the price-earning multiples will change with time and development of earnings model in certain level. In conclusion, the companies with consecutive growing earning can enjoy higher market value compared to the ones without that.
