臺灣地區發行海外存託憑證對標的股票價格變動之研究 / The Impact of Issuing GDRs on the Returns and Risks of Underlying Stocks - An Example from Taiwan

劉仲宙, Liu, Jong Jow Unknown Date (has links)
隨著世界經濟的發展與科技的進步,企業面臨愈來愈激烈的競爭環境,而愈趨多元化的國際金融市場則為企業融資方式帶來更多的選擇,也使企業能募得低成本的資金,以因應成長所需。   海外存託憑證代表標的股票在國外流通,並與標的股票產生價格上的互動。本研究探討台灣地區股票上市(櫃)公司宣告發行海外存證的訊息效果,及海外存託憑證發行後對標的股票的報酬與風險的影響。   在宣告發行的訊息效果部分,本研究的研究範圍以民國84年2月28日前,曾宣告將發行海外存託憑證的上市(櫃)公司為樣本,研究期間則為為宣告日前130日至宣告日後 30日為主;至於海外存託憑證發行後,對標的股票的報酬與風險影響部分,本研究的研究範圍以民國83年9月30日前,已發行海外存託憑證的上市(櫃)公司為樣本,研究期間則為為宣告日前130日至宣告日前31日,及掛牌日前30日至掛牌日後130日為主。   本研究以事件研究法為主,配合類似事前事後設計的實驗設計,分別以以市場模式、市場調整模式、及平均報酬調整模式估計超常報酬,得出下列結論:   1. 宣告發行海外存託憑證,對標的股票價格可能並不會產生超常報酬。造成此種結果的原因可能與訊息揭露時點、訊息求證、及投資人視為利空等有關。   2. 海外存託憑證掛牌日,對標的股票價格可能會產生正的超常報酬。原因可能為投資人樂於擁有績優或前景看好的上市公司股票,且海外存託憑證的發行人可能有拉抬標的股票價格的現象,以便藉機抬高海外存託憑證發行價格,為本身募集更多資金。   3. 海外存託憑證掛牌後,可能並不會加大標的股票報酬的波動幅度。此種結論與過去研究結論相悖,可能是因為國外投資人惜售造成回贖量小,或是由於本研究的樣本數不足。

上市公司購併宣告對股東財富影響之研究 / The Research of M&A Effect on Stockholders Wealth

陳匯中, Cheng, Huey Chung Unknown Date (has links)
臺灣在面臨臺幣升值、工資與房地產價格狂漲的經營困境之下,企業開始藉由購併活動來取得現成的管理經驗與經營資源,來彌補對海外經營環境缺乏認識或經驗不足的弱勢。國內企業因經營規模普遍太小,難以發揮規模經濟的綜效,以致相對削弱競爭能力,不利於產業升級。近年來由於政府的支持與推動,以及企業多年來累積的財富與股票市場的推波助瀾,更興起企業購併的風潮。而本研究的目的,為探討資本市場對上市公司的購併宣告有何反應。   本研究以民國78年1月至83年12月為研究期間,經蒐集相關資料後,選取42個進行購併宣告的上市公司樣本,利用傳統事件研究法及殘差分析,探究臺灣上市公司進行購併活動的宣告對股東財富之影響。所獲得的結論如以下四點:   1.就全體樣本實證結果顯示,上市公司的購併宣告將影響公司的市場價值,在宣告日當天有顯著正的異常報酬值1.192%(t=2.195),表示股東財富將因此宣告訊息而增加。2.國際購併與國內購併的事件宣告在資本市場的反應均具有正的異常報酬值,但其結果不甚相同。3.在購併型態方面,非相關購併事件因為產業關聯性較低,綜效的價值較不能發揮,因此,此二購併類型的差異效果的確存在。4.位處不同產業的購併宣告亦有所差異。

台灣上市櫃公司私募市場之研究 / A study on the private placement in Taiwan listed and OTC companies

施欣萍, Shih,Hsin-Ping Unknown Date (has links)
本論文以自民國九十二年一月一日至民國九十九年十一月三十日止辦理私募增資之上市櫃公司為研究對象,把應募人分為內部人與非內部人,透過事件研究法與迴歸分析法分別探討私募宣告效果與影響折溢價幅度之因子。 首先,採事件研究法,討論內部人與非內部人在私募宣告時是否有異常報酬,並從內部人之累積異常報酬評估是否有內線消息產生,結果顯示,在宣告日前,不論內部人或非內部人之累積異常報酬皆呈現不顯著負值,因結果不顯著,故沒有證據顯示有內線消息。本研究之內部人私募宣告當天效果為負,且宣告日當天並沒有顯著之累積異常報酬,探究其原因,可能是在股東會決議日當天訊息尚未完全散佈,把時間拉長到宣告日後第二十一天,標準化累積異常報酬轉為顯著正值,整體來說,宣告效果是正的,只是反映的時間較長,此可能跟投資人接收訊息的快慢有關,也表示在宣告日後,看好公司未來發展,因此,累積異常報酬為正。 實證結果顯示,內部人之折溢價幅度與每股盈餘、私募金額取對數、負債對權益比有高度相關;此外,從非內部人折溢價樣本之迴歸結果,可看出每股盈餘、總資產報酬成長率、私募金額取對數對於折溢價幅度有顯著影響。綜上所述,影響內部人與非內部人折溢價因子之不同點在於總資產報酬成長率與負債對股東權益比,而共同點影響因子為每股盈餘與私募金額取對數。 / Collected from the Market Observation Post System in Taiwan Stock Exchange, the sample includes private placements of all listed and OTC firms in Taiwan stock market during January of 2002 to November of 2010. This study classifies investors into insider and non-insider, and then examines the announcement impact and the factors of price discount (premium) in private placement through the event study and the regression analysis. By employing event study, we find that insider and non-insider have insignificant negative accumulative abnormal return before the announcement date. Therefore, there is no evidence for early information leakage. The announcement stock price effect on the shareholders’ meeting is insignificantly negative. As a result, we can’t expect the investors would instantly, correctly respond to this information on the announcement date. However, the announcement stock effect, represented by the calculated accumulative abnormal return, for the long time is positive, and it implies the investors expect the firms to have good performance after the event. Empirical evidence in regression analysis shows that the private placements for Taiwan’s companies are selling at discounts (premiums) and it has high correlation with the company’s earning per share, the proceeds of private placement and the return on total assets growth rate for insiders. In addition, these three variables of the company are the significant explanatory variables for the magnitude of the discounts (premiums) of non-insiders.

我國認購(售)權證課稅制度合理性之探討

陳欣怡 Unknown Date (has links)
認購(售)權證課稅之問題在券商與財政部間已進行將近八年的時間,卻一直達不到共識。本論文就此問題做一深入之探討,究竟目前認購(售)權證之課稅規定是否妥當?若否,應如何課稅才算合理,以促進認購(售)權證市場的發展? 本研究分為兩個部分,第一部分係整理認購(售)權證課稅問題之各方論點,並對其提出評析;第二部分則主要利用事件研究法(event study)探討目前市場投資人對認購(售)權證課稅方式之反應。 在認購(售)權證課稅問題之制度面,本研究有以下結論:認購(售)權證之收入屬預估性所得,因認購(售)權證之收入在收現時係屬預收收入,需待履約時才能確定成本費用。預估性所得在整各交易流程的實現上充滿了不確定性,因此,對其成本費用之認定應較寬鬆;在履約日當日收入與成本費用即可確定,且須和其他部門分開列帳,認購(售)權證之收入與成本費用可單獨確定,且因果關係亦相當明確;認購(售)權證之風險可合理預估,並進行理性之避險行為,而避險對股票之買賣行為與一般投資思維有異,可以確定該買賣標的股票之動作係為減少履行認購(售)權證義務而可能產生之損失,故就本質而言,和認購(售)權證為同一交易。 本研究之實證共舉八個事件日進行討論,但是僅有券商敗訴之事件日結果較顯著,本研究推論可能的原因包括因為發行權證公司之業務有太多種類,因此受影響的因素較多,事件日發生之影響可能被其他和發行權證公司相關之議題抵消;此外,因課稅問題未解決,權證市場之環境尚未成形,投資人對此金融商品之興趣相對低落,因此對此議題之敏感度也較低;最後,因這八個事件日當中,對課稅權證相關之爭議結果其實都是紙上數字,對投資人來講,感受較不深刻,僅有在第一次取得敗訴時,真有費用產生之可能性,投資人才較有反應。 / The controversy of Tax Regulation of warrant between stockbroker and Ministry of Finance has been stalemate for almost 8 years. This study tries to discuss that whether the tax regulation of warrant are adequate? If not, how should it be to liven up the market? This study is divided into two parts. The first part is to collect viewpoints of every aspect, then analyze and bring up new ideas. The second part will use event study research to discuss how the market responds to the tax regulation of warrant. As to the system of the regulation, this study concluded as follows. Since the income is classified to unearned revenue when cash was received, and not until exercise day can the cost and expense be ascertained, the income of warrant belongs to predicted income. The process of completing the trade of predicted income is filled with uncertainties; therefore, the related cost and expense should be identified more flexibly. On the exercise day, the income, cost and expense of warrant are assured, and should be accounted separately from other segments; thus, the causal relationship is definite. The risk of warrant can be reasonably evaluated, and proceed rational hedge. Furthermore, the considerations of buying and selling target stocks are different from regular investment. Accordingly, it can be assured that the buying and selling are for minimizing the lost to meet the obligation of issuing warrant. Therefore, as to the essence, they are in the same trade process as issuing warrant. This study takes 8 event days to discuss how the market responds to the issue of tax regulation of warrant. Only the date that stockbroker lost the lawsuit that the result are significant. This study infers that the probable reasons include that: there are too many businesses for the warrant issuer. Too many related issues may influence the market price of the issuer, thus offset the effect of tax event. Besides, the tax problem remains unsolved. The macro environment is immature, and diminishing the interest of investors, then consequently insensitive to the related event. At last, as to these 8 events, the results are all figures on the paper. Only when the stockbroker lost the lawsuit for the first time and will be real cash outflow that investors realize that there are losses. Hence, the respond are more significant.

影響長期性資產減損損失認列之決定性因素與其市場反應-以美國財務會計準則第144號公報為例

邱永昌 Unknown Date (has links)
由於資產的減損會大幅影響會計盈餘與資產價值,且一般公認會計原則給予公司管理階層在資產減損的處理上有很大的彈性,因此長久以來,長期性資產減損的議題都吸引著經理人、會計資訊使用者、媒體、政府規範單位以及學術界的注意。美國財務會計準則委員會在2001年10月發佈了財務會計準則第142號與第144號公報來修正原本規範長期性資產減損的第121號公報,其中第144號公報主要規範的資產類別為非商譽類的長期性資產減損會計處理。雖然144號公報施行至今已有數年的時間,但與144號公報相關的實證研究極少,因此本文將時序拉回公司採用144號公報的首年度,分析公司認列長期性資產減損的決定性因素以及股票市場對公司資產減損宣告的反應。 在公司認列長期性資產減損的決定性因素方面,實證分析結果顯示公司長期性資產減損之金額會受到公司之經濟因素(股票報酬、資產報酬率成長率)以及報導動機(總資產、盈餘平穩化、經理人變動)影響,由此可知公司認列資產減損的行為與動機除了包含144號公報內所規範的經濟因素外,尚包括傳統盈餘管理理論中所提出的報導動機。 而在分析股票市場對公司資產減損宣告反應的研究中,先前的研究均是假設市場上對於資產減損的認列為非預期的,然而市場上對於資產減損損失的認列並非全然皆為非預期的,投資人亦有可能透過公開資訊的蒐集以及理性分析後會將預期資產減損損失考慮在投資策略中;因此本文利用迴歸模型預測,將長期性資產減損分為投資人預期與非預期兩種類型進行分析,以分別探討投資人對預期與非預期的資產減損宣告有何不同的反應。實證結果顯示,不論資產減損是否被投資人預期,股票市場對於資產減損的消息並沒有顯著反應。

股價行情與金融研究機構彙報發佈有何影響:根據道瓊30成分股 / How Financial Research Firms’ Reports Affect Stock Prices: Evidence from the Dow 30

李英豪, Ying-Hao Lee January 1900 (has links)
根據效率市場假說(Efficient-market hypothesis,EMH),倘若市場是具有效率性的,投資者無法預測股票未來的走勢,包括專業的基金經理人員。但是,在許多財經新聞媒體、商業報紙與商業週刊中,發現證劵經理人或分析師在金融市場中大膽的預測股票未來的走向。這些資訊吸引許多投資者紛紛進場投資,期許能獲得更多利潤。然而,投資者卻忽視發佈的資訊時間點的重要性,幾乎很難求證此消息是否真實。本研究希望探討投資機構之研究彙報能否為投資者帶來異常報酬,並印證市場效率性是否存在。本研究資料透過公開的資訊網站Yahoo Finance收集美國道瓊工業30成份股的資料之金融研究機構建議操作方向,利用事件研究法(Event Study Method)來進行分析。實證結果發現事件發生時,不論是推薦買進或賣出,平均異常報酬率(AAR)有顯著的異於零的報酬率,證實金融研究機構所建議的操作方向的確吸引到市場的注意,造成股價異常波動。而累計平均異常報酬率(CAAR)則是顯示事件發生後約4週,建議買進的事件會出現相當利潤。除此之外,本研究亦針對不同金融研究機構的績效分別進行討論,然而並無發現各金融研究機構有顯著的差異。 / According to the Efficient-Market hypothesis (EMH), if the market is to have efficiency, the investor or professional fund managers cannot predict the future trends of a stock. However, in many financial news media, business newspapers and Business Week, we can find securities managers or analysts in the financial markets boldly predicting the future direction of a stock. This information attracts many investors who enter into investments, hoping to gain more profit. However, investors have neglected the importance of published information at a point in time, and in hindsight, it was hard to verify whether or not this news is true. The present study is to investigate that the mechanism of investment research reports can bring abnormal returns for investors, and confirm the existence of market efficiency. The studies suggested actions of directing public information through research institutions news site Yahoo Finance and collected 30 constituent stocks of the Dow Jones Industrial, to analyze the use of the event study method. The empirical results show when the event occurred, whether it was a buy or sell recommendation, the average abnormal return rate(AAR)has a phenomenal rate of return difference from zero, confirming that the proposed research institutions operating direction did attract the market's attention, resulting in abnormal fluctuations of the stock price. The cumulative average abnormal return rate(CAAR) is a show about four weeks after the incident that recommends buying the event will be quite profitable. In addition, this study discussed separately the performance of different research institutions, however, it found no significant differences between various research institutions. / 目錄 摘要.............................................................................................................Ⅰ Abstract........................................................................................................Ⅱ 目錄............................................................................................................Ⅲ 圖目錄..........................................................................................................Ⅴ 表目錄..........................................................................................................Ⅵ 第壹章 緒論....................................................................................................1 第一節 研究動機.................................................................................................1 第二節 研究目的................................................................................................2 第三節 研究架構.................................................................................................3 第四節 研究貢獻.................................................................................................3 第貳章 文獻回顧.................................................................................................3 第一節 效率市場理論..............................................................................................3 第二節 效率市場層面..............................................................................................5 第三節 專家推薦層面..............................................................................................7 第四節 綜合評析..................................................................................................8 第參章 資料來源與研究方法.........................................................................................8 第一節 資料來源..................................................................................................8 第二節 研究方法.................................................................................................10 第肆章 實證分析.................................................................................................11 第一節 資料敘述.................................................................................................11 第二節 模型設計.................................................................................................13 第三節 結果分析.................................................................................................20 第伍章 結論與建議...............................................................................................33 第一節 結論....................................................................................................33 第二節 後續研究建議.............................................................................................35 參考文獻.........................................................................................................36 中文部分.........................................................................................................36 英文部分.........................................................................................................37 附錄.............................................................................................................38 附錄一 道瓊30成分股中之各證劵彙報建議買進(Upgrade)之個股平均異常報酬(AAR)與累計平均異常報酬(CAAR)圖..................38 附錄二 道瓊30成分股中之各證劵彙報建議賣出(Downgrade)之個股平均異常報酬(AAR)與累計平均異常報酬(CAAR)圖................45 附錄三 篩選後,各家金融研究機構發佈彙報之建議買進(Upgrade)之個股平均異常報酬(AAR)與累計平均個股異常報酬(CAAR)圖........52 附錄四 篩選後,各家金融研究機構發佈彙報之建議賣出(Downgrade)之個股平均異常報酬(AAR)與累計平均個股異常報酬(CAAR)圖......57 圖目錄 圖1.

台灣上市公司總經理特性對總經理更換 宣告效果影響 / The Announcement Effect of CEO Characteristics to Turnover of Listed Companies in Taiwan

李季格 Unknown Date (has links)
本研究希望能藉由股票市場對於公司宣告總經理更換之反應,了解市場對台灣上市公司更換總經理之總經理特性看法是否能反映出總經理適任與否。 本研究以2005年至2014年於證交所公開資訊觀測站之重大訊息公告專區宣告更換總經理之台灣上市公司為研究樣本,結合台灣經濟新報TEJ+自公司年報與發布消息所彙整出與總經理特性之相關資訊,再透過事件研究法計算個別公司更換總經理的宣告效果。 本研究首先探討市場對公司更換總經理之整體看法為何,再透過複迴歸分析進一步探討更換總經理之新任總經理是否由董事長兼任、總經理是否由內部最終控制者成員出任、卸任總經理之在位期間長短、卸任總經理是否離開公司、卸任總經理之選任時持股百分比等因素對宣告效果的影響。 實證結果有以下發現:(一)更換總經理前經營績效表現良好之公司,而新任總經理之職雖然非由董事長出面兼任,但公司之新任總經理仍是由內部最終控制成員中進行選派時,會帶給市場顯著負面宣告效果(二)當新任總經理由董事長兼任,且公司過去經營績效表現良好時,若卸任總經理離開公司,會對公司造成負面宣告效果,這顯示市場認為公司過去經營績效表現良好與總經理之良好管理能力有關,故當新任總經理由董事長兼任使得經營權與所有權合一時,不但會影響董事會監控之獨立性又無法將卸任總經理之優秀才能保留延續,故卸任總經理又離開公司對公司來說是個壞消息。

企業創新於併購上的價值分析 / Do Mergers for Innovation Create Value for Investors?

陳韋丞, Chen, Wei Cheng Unknown Date (has links)
Through overviewing the merger waves during the last century, we know the latest two waves result mainly from technological innovation. With the presence of M&A market, acquirers are able to gain innovation capacities by taking over innovative targets. Innovation is considered to be a source of synergies and a major motive for M&A decision. Therefore, my research focuses on whether acquisitions for innovation create value for investors in short-term and long-term perspective. By using various innovation measures, I employ event study and calendar time portfolio to examine the significance of abnormal returns. I find the abnormal returns of bidding innovative targets do not show significant difference from the peers in short-term market reaction. However, in the long-run, the group with innovative targets reports significant abnormal returns. Under multiple regression analysis, I find patent counts, total citations, and citation-weighted patent counts have positive relation with abnormal returns under WLS procedure, while only average citation yields the most consistent result under both OLS and WLS. Lastly, I confirm the relation between abnormal return and average citation measure by employing calendar time portfolio approach.

公司治理評分與主併公司併購宣告異常報酬之關連性研究 / The Research of Relationship among the Aquirers' Corporate Governance Scores and The Aquirers' M&A Announcement Abnormal Returns

蔡亹桓 Unknown Date (has links)
近年來企業之公司治理評分漸漸為社會大眾所重視,故本研究依據中華公司治理協會CG6004公司治理制度評量通用版實地評量表,選取14個評分變數,訂定一套台灣上市櫃公司的公司治理評分系統。本文則利用此系統針對2003年至2009年宣告併購的台灣上市櫃公司,共選取143個併購樣本,對於選取樣本公司進行公司治理評分。 本研究主要探討公司治理評等指標與主併公司宣告併購異常報酬之關聯性,以及影響主併公司併購宣告報酬的其他因素。透過事件研究法以及迴歸分析, 本研究之分析結果顯示:主併公司宣告併購時,在事件窗口(-2,+2)有顯著正向平均累積異常報酬。在本研究建立的公司治理評分系統當中,「董事長與總經理是否由不同人擔任」此項變數在10%顯著水準下有顯著影響,然而其他項目的公司治理評分變數並無顯著影響。並且發現主併公司市值規模與主併公司併購宣告平均累積異常報酬顯著負相關,主併公司負債比率與主併公司併購宣告平均累積異常報酬顯著正相關。最後,本研究檢視實證結果與限制並做出相關研究建議,期望能夠提供各界參考。
