企業進行購併與其公司規模關係

朱淳銘 Unknown Date (has links)
本研究搜集研究期間為1989-2005年2月的購併樣本,將主併公司按市值區分大小後,發現大公司在事件窗口(-30,10)有顯著負向的累積異常報酬率(Cumulative Abcdrmal Return;CAR),大公司在上市市場上,在金融證券業及其他產業下都有顯著負向的累積異常報酬率;大公司顯著有較高的現金比例、營運現金流量比例、Tobin’s Q和較低的帳面對市場價值比,在除去金融證券業樣本後,負債比率顯著小於小公司;集團購併、當被併公司為上市櫃、及以股票為支付方式時,大公司也都有顯著負向的累積異常報酬率;大公司購併時的相對規模顯著小於小公司。迴歸結果中,公司規模之替代變數皆顯著和累積異常報酬成負向關係。股票支付方式其累積異常報酬也顯著低於現金支付方式。Tobin’s Q的係數則顯著為正。在產業部份,金融證券業和其他產業相較之下,在宣佈購併時會得到市場較正面的反應。企業併購法的修訂實行對迴歸式並未造成結構性的改變。 / After collecting the acquisition samples of bidding firms from 1989 to February 2005 and differentiate their sizes, we found large firms have significant negative CAR (Cumulative Abcdrmal Return) in the windows of (-30,10). Large firms have significant negative CAR in public market, financial and security industry, and other industries. Large firms have higher ratio of cash/book assets, operating cash flow/book assets, Tobin’s Q and lower B/M ratio. They also have lower debt ratio after removing the samples in financial and security industry. Large firms also have significant negative CAR when they are conglomerates, the targets of theirs are public companies, or when they use equity as the method of payment. The relative size of large firms is much smaller than that of small firms. In the result of regression, the proxy of firm size has negative relation with CAR. Using equity as the method of payment has lower announcement return than cash. Tobin’s Q has a positive coefficient. Financial and security industry can get more positive responses from investors than other industries. Finally, the revised edition of Business Mergers and Acquisitions Act which has been brought into force on May, 5, 2004 does not cause structural changes in the regression models.

內部關係人持股異動行為與財務分析師盈餘預測之相關性研究

洪淑華, Hung, Su-Hua Unknown Date (has links)
台灣股市流動性高居世界之冠,交易成本低,但相對而言,內線交易的嚴重性也是眾所皆知的,國際洛桑管理學院(IMD)在1999年即將台灣股市內線交易評等為42名。足見在各界戮力全面提升國家競爭力之際,有效遏止股市內線交易,以健全股市發展,已至刻不容緩的地步。公司的內部關係人,由於職務上的關係,容易接近公司管理階層,或本身就是管理當局,極易獲取公司重大情報和足以影響股價的消息,當然也可能會影響財務預測的品質,根據以往文獻指出,內部關係人股權異動情形具有其資訊內涵。內部關係人甚至會利用與管理當局合作或是與分析師合作的方式,操縱其盈餘預測值,以安排股權異動的時點。 本研究主要的實證議題有四:(1)分析師預測修正的方向與大小,與修正日前公佈的內部關係人淨買進股數是否有關?(2)內部關係人持股變動後,分析師盈餘預測誤差是否會變小(與實際盈餘相比)?(3)實際盈餘宣告日前(後),內部關係人是否會買進較多被低估(高估)(最近一次分析師預測值低(高)於實際宣告值)的股票?(4)實際盈餘宣告日前(後),內部關係人淨買進股數是否與股票價值被低估(高估)的程度有關? 實證結果發現: 一、在大規模公司的樣本群組中,當內部關係人股權異動屬淨賣出(淨買入)的情況時,分析師會向下(上)調整其盈餘預測值。但實證結果並不支持內部關係人股權異動的程度,會顯著影響分析師盈餘預測修正幅度;就小規模公司樣本而言,則無法獲致修正日前公佈的內部關係人股權異動行為與分析師盈餘預測修正幅度有顯著相關的結果。 二、在大規模公司樣本中,內部關係人在盈餘預測揭露前一個月的淨買入比率,很有可能會使分析師盈餘預測準確度提高。其餘的分析師盈餘預測修正日前三個月的內部關係人股權異動比率,對分析師盈餘預測準確度,並沒有顯著的影響。 三、大規模公司盈餘公告日前(後),內部關係人確有可能在分析師盈餘預測高(低)估後,於盈餘公告日前增加(轉讓)持股數,而於盈餘公告日後轉讓(增加)持股。但是實證並不支持分析師盈餘預測準確度的程度,會顯著影響內部關係人的持股異動。 四、小規模公司盈餘宣告日前的樣本群組,內部關係人確有可能在分析師盈餘預測高(低)估後,於盈餘公告日前增加(轉讓)持股數。但盈餘公告日後的樣本群組無法獲致顯著的結果,也就是說內部關係人在分析師盈餘預測高(低)估後,沒有顯著的在盈餘宣告日後轉讓(增加)其持股。

我國上市公司月營業收入與股票交易量關聯性 / The Relationship among Revenue Per Month and Trading Volume

蔡醒亞, Chua, Shing-Ya Unknown Date (has links)
本論文在探討我國上市公司每月營收額對於市場交易量之影響,以瞭解每月營收額是否具有資訊內涵。我國證券交易法第36條規定,依證交法發行有價證券的公司所必須提供的財務資訊中,以每月營運情形最具即時性,但由於並未經過會計師查核、核閱等程序而缺乏可靠性。故本研究驗證缺乏可靠性的每月營收公告額,是否會影響市場投資人的投資決策。 本研究選取國內209家上市公司于民國84年至民國86年間的5395個每月營收公告為樣本,根據相關之理論及實證文獻找出可能影響市場交易量的因素─未預期營收大小及公司規模,以t檢定法及迴歸分析法檢視每月營收公告期間之資訊內涵假說是否成立。此外,本研究亦檢視在每月營收公告期間交易量的變化,是否受到其他因素影響而有所差異。實證結果顯示: 一.每月營收公告期間,交易量的變化會因為未預期營收的大小而有顯著的差異;未預期營收絕對值越大,異常交易量越大,符合幅度假說。 二.未預期營收絕對值越大者,在每月營收公告期間,其異常交易量的持續期間也會越長,符合持續期間假說。 三.每月營收公告期間,交易量並不會因為公司規模的大小而有明顯的變化,公司規模並不能解釋該期間交易量的波動。 四.將每月營收公告依月份細分發現,當公告月份屬於第一、第四季時,該月的營收公告較會被投資人所重視;反之,當公告月份屬於第二、第三季時,月營收而並不會被投資人利用作為投資時之依據。 / both

強制性財務預測對股價及交易量影響之研究

蔡玉璇 Unknown Date (has links)
本研究結合價量分析,旨在探討強制性財務預測是否具備資訊內涵,依其性質分為原始財測、正向更新和負向更新三種,循序驗證各種財務預測宣佈時,股市是否有異常價量反應。並進一步依序檢驗未預期盈餘(或更新幅度)、公司規模及行業別與股市累積異常價量之關係。最後比較『公開發行公司財務預測資訊公開體系實施要點』修改前後對研究結果之影響。本論文以民國八十二年初至民國八十七年底之上市公司為研究對象,實證結果如下: 一、股價反應原始強制性財務預測資訊較交易量快,但持續期間較短。 二、正向更新強制性財務預測發佈時,股價有顯著異常反應,但交易量卻無明顯變動。 三、負向更新強制性財務預測發佈時,價量皆有異常反應。 四、『實施要點』修改後,對平均異常報酬率的影響較大,對平均異常交易量的影響較小。 五、原始強制性財務預測發佈時,相較於訊息內容所含之未預期盈餘大小,投資者更側重公司規模及所屬行業別。 六、正向更新強制性財務預測發佈時,相較於目前公司規模之大小,投資者更重視正向更新幅度及所屬行業別。 七、負向更新強制性財務預測發佈時,投資者不只重視負向更新幅度,亦重視目前之公司規模及所屬行業別。 八、『實施要點』修改後,因放寬更新標準規定,管理當局更會利用機會高估財務預測。

我國新上市股票價格行為與長期績效之研究 / THE POST-LISTING RETURN PERFORMANCE OF UNSEASONED ISSUES OF COMMON STOCK IN TAIWAN

徐瑋霙, Hsu, Wei-Ying Unknown Date (has links)
我國股市自民國76年起,由於經濟情勢變遷,全面電腦化搓合交易,人氣與資金之大量投入,使得股市蓬勃發展;新上市股票遂成為廣受研究之課題.本研究係探討我國新上市股票上市後之股價行為及其長期績效之觀察.本研究採橫斷面設計,探討新上市股票是否有超額報酬之存在;且進一步研究可解釋超額報酬之因素.以民國76年至84年9月底共195家新上市股票為研究對象,採用敘述性統計,兩樣本T檢定及變異數分析進行測試.本研究之結論如下: 1.我國新上市股票在上市後,自第一個交易日起即具有超額報酬,且報酬快速上升,在第一百個交易日時為最高,之後緩步下滑.但直至第五百個交易日止,仍有超額報酬之存在. 2.我國新上市股票之股價行為,會受上市年度景氣之影響.股市愈熱絡,於當年度上市之股票,其超額報酬就愈大. 3.新上市公司之規模大小與其上市的股票之超額報酬間,為反向之關係. 4.在中長期下,新上市股票之承銷商為前三大承銷商者,超額報酬較低;為非前三大承銷商者,其超額報酬較高. 5.新上市公司是否為前六大會計師事務所簽證,對新上市股票之價格行為並無顯著之影響. 6.中籤率之高低與新上市股票之超額報酬間,有顯著之負向關係. 7.新上市公司發布的業績持續性之預測為較佳之訊息,則超額報酬較高;反之亦然. 8.新上市公司之產業類別與超額報酬間,並未存在顯著之關連性.

取消財務預測強制公開揭露制度之資本市場反應 / The capital market reaction to the abolishment of mandated financial forecast

周美慧, Chou, Mei - Hui Unknown Date (has links)
財務預測相較於歷史性財務報表而言,其決策之攸關性較大。我國自民國80年5月起開始實施強制性財務報表迄今,已成為資本市場中相當重要的訊息,惟隨著我國證券市場規模逐步擴大,公司面臨之經濟環境日趨複雜,為符合國際作法及實務需要,故行政院金融監督管理委員會證券期貨局於93年12月9日依據證券交易法第三十六條之一,發布金管證六字第930005938號函,修正財務預測制度改採自願公開方式(並得以簡式或完整式方法擇一為之),並參考國外有關預測性資訊公開之相關規定及實務運作方式,配合相關配套措施,以增進資本市場效率及決策品質。   宣告取消財務預測強制公開揭露制度後,實證結果顯示:(1)對股價會產生一負向的效果,有顯著的負向異常報酬產生,且消息提前反應於市場上;在交易量方面,有顯著異常增加的情形發生。(2)對資訊特性不同分組採單變量分析,結果顯示公司規模及分析師人數可解釋宣告效果大小,兩組之間均達顯著水準。(3)公司規模越大時,股價反應越小,顯示公司規模與宣告異常報酬率間呈負向關係,亦即規模效果存在;但交易量反應越大。(4)分析師人數越多時,股價反應越小;但交易量反應越大,且較少分析師人數公司來得顯著。 / Financial forcast is more relevant than historical financial statements. Our country began to implement the mandatory financial forcast since May, 1991, has already become a very important information in the capital market. While the economic environment becoming complicated, in order to meet international practices, so on December 9, 1993, change the firm can dicide disclosure their financial forcast by themselves, in order to promote the efficiency of capital market and decision quality. The empirical results show that:(1) For stock price, it will produce negative effect; on the other hand, trading volume is significant increaseing. (2) For groups with different level of information characteristics, the results show that firm size and the number of ananlysts can explain that declaring effect. (3) When the size of firm is larger, the stock price is smaller; but the trading volume is larger. (4) The number of analysts is larger, the response of stock price is smaller; but the trading volume is larger in response.

公司規模及產業競爭對於CEO現金薪酬與 正、負股票報酬不對稱關聯性之研究 / The effect of firm size and industry competition on asymmetric sensitivity of CEO cash compensation to stock returns

王姿惠 Unknown Date (has links)
本研究旨在探討公司規模及產業競爭對CEO現金薪酬與股票報酬敏感性之影響。根據Leone et al. (2006)之研究,認為依未實現利得而給付之現金薪酬將產生事後交割成本,未實現損失可能遞延CEO之決策責任。由於未實現損益可反映至股票報酬上,因此有效率的現金薪酬契約對含有未實現利得之正股票報酬的敏感性低於含有未實現損失之負股票報酬,顯示現金薪酬與正、負股票報酬之敏感性呈現不對稱關係。本研究以此文獻作延伸,探究CEO現金薪酬與股票報酬之敏感關聯性及其不對稱性關係是否受公司規模與產業競爭之影響。 以ExecuComp資料庫2000年至2009年的CEO現金薪酬樣本進行迴歸分析,結果發現公司規模愈大,現金薪酬對市場績效之敏感性愈大,顯示為避免CEO從事會計盈餘管理,公司現金薪酬之給付更著重於市場績效之衡量;產業競爭方面,產業競爭愈激烈,現金薪酬與市場績效之敏感性愈小,符合風險差異化假說。關於CEO現金薪酬與正、負股票報酬敏感性之不對稱關係,實證結果顯示大規模公司及產業競爭程度較高者對CEO決策之審慎性更加要求,因此CEO現金薪酬與正、負股票報酬敏感性之不對稱的差距愈大。 / This study investigates the effect of firm size and industry competition on the asymmetric sensitivity of CEO cash compensation to the stock returns. Leone et al. (2006) shows that since stock returns include both unrealized gains and losses, cash compensation would be less sensitive to stock returns when returns contains unrealized gains (positive returns) than when returns contain unrealized losses (negative returns). As an extension, this study examines whether firm size and industry competition affect the sensitivity of cash compensation to market performance and the asymmetry of sensitivity of cash compensation to stock returns. Based on the CEO cash compensation during 2000 and 2009 from ExecuComp database, the empirical results show that the firm size has positive effect on sensitivity of cash compensation to market performance while the industry competition has negative effect. Moreover, the asymmetry of sensitivity of CEO cash compensation to stock returns increases as firm size and industry competition increase.

兩稅合一制度下「股東可扣抵稅額」於企業評價之角色-Ohlson模型之應用 / The Role of Imputation Credits Disclosure to Firms’ Valuation after the Integration of Individual and Corporate Taxes— An Application of the Ohlson Model

張青霞, Chang, Ching-Hsia Unknown Date (has links)
依據財務會計理論,附註揭露為整體財務報表的一部份,其目的在提供投資人進行企業評價時所需之攸關資訊。兩稅合一制度實施後,不僅使稅賦型態轉變,會計原則中也新增附註揭露股東可扣抵稅額之規定,因此提供了驗證資本市場與財務報表揭露的機會,本研究即針對股東可扣抵稅揭露是否具有價值攸關性進行測試。 本研究以87年為樣本年度,分析資料完整的317家上市公司,透過Ohlson模型來檢測股東可扣抵稅額之價值攸關性,並處理Ohlson模型中兩個重要的information dynamics,以異常盈餘(xa )及其他資訊(v)做為模型中的自變數,將財務分析師之財務預測(analysts’forecasts)做為Ohlson模型中其他資訊(other information)之代理變數,以捕捉Ohlson模型中其他資訊對股價的影響。最後,考慮產業及公司規模兩項因素,觀察紡織業與電子業對股東可扣抵稅額揭露之反應以及公司規模對於價值攸關性研究的影響。 實驗結果顯示,無論以現金基礎或應計基礎衡量股東可扣抵稅額,其揭露均具價值攸關性,投資人的確使用財務報表附註揭露中有關股東可扣抵稅額之資訊於企業評價上。其次,異常盈餘與其他資訊皆能捕捉股價之變動。最後,在紡織業與電子業中雖未觀察到股東可扣抵稅額之揭露具有攸關性,但公司規模的因素則無論在全體樣本或各別產業中皆具影響力。 / According to modern accouning theory, footnote disclosures are an intergrated part of the overall financial statements. The purpose of footnote disclosures is to provide value-relevant information in assisting investors’ valuation process. After Taiwan’s 1998 Tax Reform, which intergrates the individual and corporate taxes, the current GAAP requires a footnote disclosure of imputation credits (IC). This provides a good chance to test how Taiwan’s stock market reacts to such disclosuer. The main purpose of this study is to examine the value relevance of IC disclosure to investors’ equity valuation. This study uses Ohlson’s (1995) model to analyze 317 firms listed on Taiwan’s Stock Exchang (TSE) during 1998. To estimate the abcdrmal earings and other information (captured by analysts’ forcasts), this study adopts Dechow, Hutton, and Sloan’s(1999) methodology. We also investigate the effects of industry and firm size on the value relevance of IC disclosure. The empirical results reveal three findings. First, there is a positive association between IC and stock price in TSE. Therefore, the IC disclosure is value relevant to investors’ equity valuation. Second, abcdmal earnings and other information can both explain stock price behavior. Finally, when we focus our sample on the textile and high-tech industries, no significant association between IC disclosure and stock price can be found. When we further consider firm size, however, the value relevance of IC disclosure becomes significant. In other word, the value relevance of IC disclosure may be affected by firm size.

股票報酬決定因素及股票報酬與盈餘間關係之研究 / The Determinants of Stock Returns and the Relationship between Stock Returns and Earnings

彭火樹, Peng, Huo-Shu Unknown Date (has links)
台灣早期有關系統風險(β)的研究皆指出β不能解釋台灣股票報酬的變異,故控尋更能解釋股票報酬的風險因素為本文的主要目的之一。 本研究分析民國71年7月至85年5月股票上市公司資料(排除金融、保險、及變更交易方式的公司)。因民國79年股價指數從2月的最高點12,495急遽下滑至10月的2,560,故分析上將79年度予以排除。在71年7月至78年12月的時段中,整體市場因素(RM-RF)不能解釋股票報酬的變異。此點發現與台灣早期研究的結論一致。其他變數顯著者僅有與規模有關的因素(SZSMB),或與負債比率有關的因素(DEHML),其中以 SZSMB的解釋能力最強。在民國80年1月至85年5月的時段中,所有模式中整體市場因素( RM-RF)的係數皆顯著,並且是所有因素中最顯著者。這點發現與前時段(71年7月至78年12月)的結果有很大的不同。其他的變數顯著者,有代表成長機會的BMHML(與淨值市價比有關的因素)、EPHML(與益本比有關的因素)、或CPHML(與營運現金市價比有關的因素),及代表利率結構有關的風險因素TERM(與利率期間結構有關的風險溢酬)、或DFT(與利率違約風險有關的風險溢酬)。其中以(RM-RF)、EPHML、CPHML及TERM的風險組合最能解釋股票報酬的變異。 應用更完整的股票報酬解釋變數,探討股票報酬與盈餘間的關係,亦為本文主要目的之一。經分析以(1)各時段最能解釋股票報酬的因素組合為基礎,計算異常報酬;(2)單獨的以整體市場因素(RM-RF)為基礎計算異常報酬,然後再分別估出盈餘反應比較係數(ERC)比較之。結果顯示,以各時段最能顯著解釋股票報酬的因素組合為基礎的ERC為正的顯著,且其ERC大於只以整體市場因素(RM-RF)為基礎所算出的ERC。 另外,關於盈餘品質假說之測試,經以公司規模大小為虛擬變數放入迴歸式中,結果顯示,代表大公司的虛擬變數之係數時而為正,時而為負,且都不顯著,故盈餘品質假說未獲得支持。 再者,關於成長機會與ERC關係之測試,經以公司成長機會大小為虛擬變數放迴歸式中,結果顯示,代表成長機會的虛擬變數之系數時而為正,時而為負,且大都不顯著,故成長機會大的公司之ERC大於成長機會小的公司之ERC的假說,未獲得實證的支持。 / Earlier studies (Chen 1990; Chiu 1990; and Wang 1992) found that systematic risk (β) could not explain the variance of stock returns in Taiwan. The findings were inconsistent with the Capital Asset Pricing Model (CAPM). One of the major purposes of this paper is to examine the factors that have higher explanatory power of stock returns. To test the hypotheses, this study uses the data of Taiwanese listed companies covering the period from July 1982 to may 1996. The 1990 data are excluded because the stock market index climbed to a record high of 12,495 in February 1990 and then fell sharply to allow level of 2,560 in October 1990. The "crash" might cause structural changes in stock market, so the analyses are conducted separately for the periods before and after the crash, namely the prior-crash period (from July 1982 to December 1989) and the post-crash period (from January 1991 to May 1996). The empirical results show that for the prior-crash period the overall market factor (market returns minus risk free rate, RM-RF) can not explain the variance of stock returns. The findings are consistent with those of previous studies. However, we find that the factor-related to size (SZSMB) and the factor related to debt/equity ratio (DEHML) have significant association with stock returns. Furthermore, SZSMB has higher explanatory power. In contrast, the overall market factor is the most significant factor for the post-crash period. Other factors that are significant consisted of (1) proxies for growth opportunities, including book-to-market equity (BMHML), earnings/price ratio (EPHML), and cash flow/price ratio (CPHML), and (2) the factors related to interest structure, including term structure (TERM) and default risk (DFT). Among these factors, the set of RM-RF, EPHML, CPHML, and TERM explains the variance of stock returns most. Another purpose of this paper is to use the aforementioned findings to study the relationship between stock returns and earnings. The results show that the earnings response coefficients based on the most explanatory factor portfolio of each period are positive and significant, and are greater than those based on the traditional systematic risk (β). The tests for earnings quality hypothesis indicate that the coefficients of the dummy variable proxies for big companies are insignificant. The earnings quality hypothesis is not supported. The tests regarding the relationship between growth opportunities and earnings response coefficients show that the coefficients of the dummy variable proxies for high growth companies are unstable. The hypothesis that the earnings response coefficients of high growth companies are greater than those of low growth companies is not supported by empirical evidence.
