盈餘可預測性與財務分析師之預測偏差性研究 / Earnings Predictability and Bias in Analysts' Forecasts

施岑佩, Shih, Tsern-Pey Unknown Date (has links)
本研究藉由探討公司盈餘的可預測性與財務分析師預測偏差性的關係,俾瞭解財務分析師獲取私有資訊的動機與預測偏差性的關係,本研究並擬進一步探討,當財務分析師預測資訊成為已公開資訊之時,市場上之投資者對於財務分析師此策略性的預測偏差性行為,是否具有辨識性,並能進一步的在股價中加以反應調整。經由實證結果,本研究獲致如下的結論: 1.財務分析師在短期的各年度預測值中,呈現不同程度的預測偏差性,但以整個樣本期間的長期平均而言,財務分析師並未呈顯著的預測偏差性。 2.公司盈餘可預測性愈低,財務分析師樂觀性預測偏差愈高。 3.公司規模愈大,財務分析師樂觀性預測偏差愈低。 4.公司產業別、內部持股比率、上市期間長短、市場風險與股票交易週轉率對於財務分析師預測偏差性不具有影響性。 5.就市場平均性而言,可完全反應調整財務分析師的預測偏差性。 6.市場上無法反應調整財務分析師對於低可預測性公司具較高程度的預測偏差性。

財務分析師盈餘預測修正決定因素之實證研究 / The Causes of Financial Analysts' Earning Forecasts Revision - Empirical Study

陳正妮, Chen, Cheng Ni Unknown Date (has links)
本論文的目的,在探討財務分析師盈餘預測修正的決策過程。因為財務分析師可以說是市場上的專業分析者,故其決策過程特別讓人感到興趣。藉著相關性的迴歸分析,將讓我們了解到分析師的盈餘預測修正可能受到修正前何種事件的影響。   本研究依據文獻探討及延伸發展出四個可能會影響分析師盈餘預測正修正方向及幅度的變數,分別是分析師預測修正期間(兩次預測的間隔期)的累積股票報酬率、未預期到的公司管理當局盈餘預測、未預期到的公司期中盈餘以及未預期到的公司期中銷貨。研究期間是從民國七十九年至八十二年,研究的對象則是「財訊」月刊內的研究分析人員(財務分析師)在月刊上所刊載的上市公司盈餘預測。   實證結果顯示,在對分析師預測修正的幅度上,以未預期的公司管理當局盈餘預測及未預期的公司期中盈餘兩者有影響力,且如假說預期般地與因變數呈現正相關。在對分析師預測修正的方向上,則四個自變數皆有影響能力,其中前三個自變數與分析師預測修正方向呈現正相關,但最後一個變數則與假說相反地呈現負相關。   本研究結果背後可能的原因探討如下:公司管理當局發佈的盈餘預測和公司期中盈餘兩者對分析師的盈餘預測修正方向與幅度上皆有正向影響力,可能意味著此二種資訊的品質具參考性,故才值得專業分析師的青睞。而分析師預測修正期間的累積股票報酬率只對盈餘預測修正方向上有正向的解釋力,暗示著分析師在預測修正時並未完全重視此項資訊。至於公司的未預期期中銷貨對分析師的盈餘預測修正方向上有負向的影響作用,則此異常現象留待後續研究者進一步的探討與測試。

分析師盈餘預測次數與機構投資人投資偏好之研究 / A study of analysts' earnings forecast numbers and institutional investors' preferences

黃聿華 Unknown Date (has links)
機構投資人的交易動向以及分析師的研究分析報告與買賣評等是台灣股市散戶投資者甚為重視的兩大資訊參考依據,也是本文主要的研究重心。本文主要研究目的在於探討機構投資人投資行為與分析師盈餘預測次數之間是否存有對彼此互相正向影響的關係,並以三大法人持股比例作為前者的代理變數,為處理兩變數之間的內生關係,本研究建立聯立方程式系統模型同時估計各解釋變數之係數;本文次要目的為兼論機構投資人(三大法人)與券商分析師分別偏好投資於或關注追蹤具有哪些特性之公司。 在主要研究主軸方面,本研究實證結果發現,三大法人全體持股比例與外資券商分析師盈餘預測次數兩者間具有正向影響彼此的關係,但在國內券商分析師方面,僅三大法人全體持股比例對國內券商分析師盈餘預測次數有顯著正向影響,國內券商分析師盈餘預測次數對三大法人全體持股比例則不具顯著影響。而將三大法人全體分為投信、外資、自營商各別探討時,僅外資法人與券商分析師之間符合本研究預期的結果(機構投資人的投資行為與券商分析師的盈餘預測次數兩者間具有正向影響彼此的關係),且無論是外資券商分析師抑或本國券商分析師,此正向關係均顯著存在;而投信與自營商的投資行為跟券商分析師盈餘預測次數之間的關係,則未能全然符合本研究之預期。

經理人性別差異與自願性盈餘預測關聯性之研究 / Gender difference and management earnings forecasts

邱逸婷 Unknown Date (has links)
本文旨在探討經理人性別差異與自願性盈餘預測之關聯性,即公司經理人性別是否會對其自願性盈餘預測偏差性及自願性盈餘預測準確度造成影響。由過去有關性別差異之研究可發現女性具有規避風險、保守行事…等特點,故本研究欲探討經理人性別差異對自願性盈餘預測之影響。實證結果發現:女性經理人進行自願性盈餘預測時,盈餘預測值較保守。相反的,男性經理人進行自願性盈餘預測時,盈餘預測值則較具樂觀性。再者,當公司經理人性別為女性時,自願性盈餘預測準確度較高。 / In this thesis, I explore the association between gender differences and the management earnings forecasts. Prior studies show that, in general, women are more risk adverse and act more ethically than man. Therefore, I examine whether the gender of management affects the bias and accuracy of management earnings forecasts. Consistent with my predictions, the results show that female CEOs release more conservative forecasts than their male CEOs counterparts. Moreover, I also find that female CEOs issue less accurate earnings forecasts compared to male CEOs. Overall, this study provides evidence that there are the relationship between gender difference and the bias of management earnings forecasts.

利用JavaScript Application Framework與CouchDB實作協作雲機制──以盈餘預測系統為例 / The implementation of collaboration cloud mechanism via JavaScript Application Framework and CouchDB ── using earnings-predicted system as example

楊凭哲 Unknown Date (has links)
本研究主要是想要基於協作雲概念下實作一個系統,並且有離線儲存、同步 技術、版本控制等功能,因為 CouchDB 的特性有自動同步與離線儲存技術,符合 協同合作的要求,因此選用 CouchDB 當作系統實作資料庫的選擇,另外也針對 CouchDB 的同步與轉換機制做了詳細的討論。而在系統程式語言方面,為了達到離 線儲存的需求,簡單前後端語言溝通的負擔,選用了 JavaScript Application Framework,採用的是純粹的 JavaScript 語言,客戶端用了 jQuery、YUI3 等JavaScript,伺服器端使用的是 Node.js,達成了一種程式語言,兩個執行時間的條件。確定系統框架與資料庫之後,最後使用盈餘預測系統來做為此實作之範例。

管理當局持股比率與管理當局盈餘預測準確度、盈餘管理關係之實證研究 / The Relationship between Managerial Ownership and Earnings Management-Empirical Stydy

周淑貞, Chou, Shu-Chen Unknown Date (has links)
本論文以公司規模大小、公司成長率、盈餘變異程度、盈餘持續率、負債比率、系統風險、以及產業別為控制變數,探討管理當局持股比率與管理當局自願性(強制性)盈餘預測準確度、盈餘管理程度之關係。並進一步探討管理當局持股比率與七個控制變數之交互作用對管理當局自願性(強制性)盈餘預測準礁度及盈餘管理程度之影響。   本實證研究結果發現:   1、自願性盈餘預測方面:   (1)管理當局持股比率越高且盈餘變異程度越大之公司,盈餘預測誤差越高,盈餘預測準確度越低。   (2)管理當局持股比率越高且負債比率越高之公司,盈餘預測誤差越高,盈餘預測準確度越低。   (3)產業別會影響其預測準確度,而產業中以鋼鐵業之盈餘預測準確度,顯著較高。   (4)公司成長率越高、盈餘持續率越高,其盈餘管理程度越高。   (5)產業中以電子業有顯著較高之盈餘管理程度。   2、強制性盈餘預測力面:   (1)管理當局持股比率與盈餘預測準確度成正相關。   (2)公司規模與盈餘預測準確度成負相關。   (3)盈餘持續率與盈餘預測準確度成負相關。   (4)產業別確實與強制性盈餘預測準確度有關,其中以電子業之盈餘預測準確度顯著較低。   (5)管理當局持股比率越高之紡織業其盈餘預測準確度顯著較低。   (6)強制性盈餘預測並無顯著的盈餘管理情況產生。   3、綜合結論:   (1)自願性之盈餘預測準確度高於強制性之盈餘預測準確度。   (2)自願性之盈餘管理程度高於強制性之盈餘管理程度。 / This research hypothesizes that the level of managerial ownership that controlling for earnings growth、earnings variability、earnings persistence、company risk、 debt、industry、and size has effect on both the magnitude of forecast precise of voluntary(compelling) forecast and the magnitude of discretionary accounting accrual adjustment.   In addition,this study examines that there are interaction of ownership effects on both the magnitude of forecast precise of voluntary (compelling) forecast and the magnitude of discretionary accounting accrual adjustment.   The empirical results show as follow:   1、Voluntary forecast aspect:   (1) Managerial ownership is negatively associated with the magnitude of forecast precise.   (2) Managerial ownership of is positively associated with the magnitude of discretionary accounting accrual adjustment.   2、Compelling forecast aspect:   (1) Managerial ownership is positively associated with the magnitude of forecast precise.   (2) Managerial ownership is not associated with the magnitude of discretionary accounting accrual adjustment.   3、Conclusion explication:   (1) The magnitude of forecast precise of voluntary forecast is more than that of compelling forecast.   (2) The magnitude of discretionary accounting accrual adjustment of voluntary forecast is more than that of compelling forecast.   (3) Industry variable indeed affects both the magnitude of forecast precise and the magnitude of discretionary accounting accrual adjustment.

會計保守性與分析師盈餘預測關係之研究

李汶伶, Lee, Wen-Ling Unknown Date (has links)
當企業的經營面臨不確定的情況時,使用穩健原則固然是可靠的,但是公司如果過度的使用穩健原則來操縱財務報表,將使資產和盈餘嚴重低估和扭曲,因此反而會降低財務報表的可靠性以及攸關性。公司的財務報表是財務分析師預測的來源之一,故當公司的盈餘由於受到管理當局對會計保守程度之操縱而有較大波動幅度時,若分析師相信公司當期盈餘是對未來盈餘的無偏誤預測指標,則財務分析師將會被誤導。因此,公司的會計保守程度對分析師盈餘預測的誤差和不同分析師間對盈餘預測意見不一致之程度應該有重大的影響。   本文以民國90年至94年之上市公司為研究對象,經由迴歸模型來分析公司會計保守性與分析師盈餘預測誤差與盈餘預測分歧程度間之關係,以檢視財務分析師是否能察覺保守性會計對公司盈餘的影響而反映於其盈餘預測中。結果發現會計保守性對分析師盈餘預測屬性均有正向影響,表示財務分析師在預測公司未來盈餘時會對管理當局所選擇的會計保守程度加以評估,並考量管理當局利用會計保守性進行盈餘管理的情形,進而影響其對公司未來盈餘的預測。 / Management may overuse accounting conservatism to manage the financial statements and undervalue assets and earnings and reduce the reliability and relevance of financial statements though conservatism is an increasing trend in accounting practice. The conservative information may lead analysts to biased forecast when a company’s earning has high volatility. Consequently, the extent of accounting conservatism should have significant effect on the analysts’ earnings forecast errors and forecast dispersion. This study examines the relationship of accounting conservatism and analysts’ annual earnings forecast errors and forecast dispersion by using a sample of listed firms in Taiwan. The results show that accounting conservatism has a positive relationship with the analyst earnings forecast errors and forecast dispersion. It implies that financial analysts may evaluate the extent of accounting conservatism and make adjustment in earnings forecast.

管理當局能力與管理當局自願性盈餘預測之關聯性 / The Relationship between Managerial Ability and Management Earnings Forecast

林姿均, Lin, Tzu Chun Unknown Date (has links)
本研究旨在探討管理當局發佈自願性盈餘預測意願、預測精確度、預測型態與管理當局能力之關聯性,並進一步檢測能力較佳之管理當局所發佈之盈餘預測對投資人是否具增額資訊內涵。 實證分析結果顯示管理當局能力與管理當局發佈盈餘預測之機率呈顯著正相關,亦即管理當局能力愈好,發佈盈餘預測之機率愈高;再者,本研究發現能力愈佳之管理當局,其盈餘預測之精確度亦會較高;而實證結果亦顯示當管理當局能力較好時,較願意以資訊量較多之完整式財務預測型態發佈財務預測。增額測試結果則顯示市場對於能力較佳之管理當局發佈之自願性盈餘預測反應程度較高。 / The primary objective of this thesis is to explore whether the managerial ability is related to management earnings forecast, earnings forecast accuracy , and disclosure format. Additionally, this thesis investigates whether managerial ability increases the informativeness of management earnings forecast for (potential) investors. Empirical results show that managers with superior ability tend to announce management earnings forecast and when managers have better ability, they shall announce more precise management earnings forecast. About disclosure format, this thesis finds that managers with superior ability prefer to announce complete earnings forecasts than simple ones. Additionally, market reaction will be more to the informativeness of management earnings forecast which made by managers with better ability.

34號公報對於管理當局盈餘預測以及分析師盈餘預測修正影響之研究 / The research of the correlation among SFAS No.34, management earnings forecast and analyst's revision of management earnings forecast

簡佳賢 Unknown Date (has links)
本研究之目的在探討,上期對本期所做之盈餘預測與本期實際盈餘間誤差所產生之未預期盈餘,對於管理階層在本期預測下期盈餘以及財務分析師針對該預測所作之預測修正,即對於該兩者的攸關性是否會隨著34號公報之實施而提高,也就是說,在34號公報實施之後,未預期盈餘對於管理當局盈餘預測以及分析師預測修正之影響,是否會更加顯著相關。 實證結果顯示,不論34號公報適用前後,管理當局盈餘預測與未預期盈餘之間皆具有攸關性,但在34號公報適用之後,兩者之間的顯著性並未增強;而另一方面,在34號公報適用前後,財務分析師盈餘預測修正與未預期盈餘之間皆具有攸關性,且在34號公報適用之後,兩者之間的顯著性有增強。 / This thesis examines whether the issuance of SFAS No.34 can heighten the association between the unexpected earnings for current period and the management earnings forecast for the next period. This research also examines if the issuance of SFAS No.34 will heighten the relationship between the unexpected earnings for current period and the analysts’ revision of the management earnings forecast for the next period. The unexpected earnings mean the difference between the earnings forecast for current period and the actual earnings in current period This thesis finds that there is a negative association between management earnings forecast and the error of the expected earnings whether SFAS No.34 has been issued or not, but the issuance of SFAS No.34 doesn’t heighten the association between the management earnings forecast and the error of the expected earnings. Besides, the result of the research shows that there is a positive relationship between the analyst’s revision of the management earnings forecast and the error of the expected earnings. Furthermore, the relationship is heightened by the issuance of SFAS No.34.

管理當局能力與強制性盈餘預測之關聯性-來自中國A股上市公司的實證分析 / The Relationship Between Managerial Ability and Mandatory Forecast: Evidence from China

熊曦, Xiong, Xi Unknown Date (has links)
本研究以中國2007年至2013年盈餘預測的A股上市公司為主體。探討管理當局發佈強制性盈餘預測的預測形態、預測誤差以及市場反應與管理當局能力之關聯性,並進一步檢測管理當局能力是否影響到其對於強制性盈餘預告門檻的規避以及對於來年發佈自願性業績預測的意願。 實證的結果顯示管理當局能力越好其提供的強制性盈餘預測的形式越精準其預告資訊含量越多;再者,管理當局能力越好,其盈餘預測的誤差越低;實證結果也證明了市場對於能力較佳之管理當局所發佈的強制性盈餘預測的反應程度也較高。增額測試的結果顯示管理當局能力佳者盈餘品質較佳,具體表現為:相較於能力差的管理者,管理當局能力較好時不會通過盈餘管理去避免導因於產生增長50%或是下降50%而強制發佈盈餘預告的門檻。另外,管理當局能力越好,其在隔年度發佈自願性盈餘預測的幾率也越高。 關鍵詞:管理當局能力、強制性盈餘預測、預測形態、盈餘預測誤差、市場反應 / This thesis focuses on mandatory forecast issued from 2007 to 2013 in China and investigate whether managerial ability is related to mandatory forecasts types, forecast error and market reaction. Additionally, this thesis also examines whether managerial ability decrease the likelihood to avoid mandatory forecast thresholds. Finally, whether the managerial ability will increase the probability of issuing voluntary forecasts in the following year is an interesting but unsolved issue; I will fill the gap. Empirical results show that managers with superior ability tend to issue mandatory forecasts in the more precise type. As for the accuracy, the mandatory forecasts issued by better managers tend to have less error. I also find that managerial ability can promotes the informativeness of management earnings forecasts for the public. Additionally, high ability managers are less likely to avoid the thresholds of mandatory forecasts. Furthermore, better managers are more likely to issue voluntary forecasts in the following year of mandatory forecasts. Key Words: Managerial Ability, Mandatory Earnings Forecast, Forecast Format, Forecast Error, Market Reaction.
