月營收宣告資訊移轉效果之研究-以資訊電子業為例

利浩廷 Unknown Date (has links)
有關盈餘資訊之研究,早期多研究其資訊內涵(影響盈餘宣告公司本身),近年來則研究資訊移轉效果(影響非盈餘宣告公司)。月營收之宣告雖非盈餘之直接資訊,但公司收入與成本比率短期間內變化不大,所以月營收之宣告能有效預測盈餘。根據國內學者近年來的研究,大都肯定月營收之宣告具有資訊內涵,但有關月營收宣告的資訊移轉效果國內卻無相關研究,又上市公司股票市場的成交金額大部分集中在資訊電子業股,因此本研究欲探討資訊電子業月營收宣告的資訊移轉效果,以了解資訊電子業月營收資訊是否受投資人重視,進而影響其投資組合。 本文的主要探討:一、資訊電子業月營收宣告是否有資訊移轉效果,二、資訊電子業中同產業內是否具有資訊移轉效果,三、探討好壞消息的差異是否影響資訊移轉效果,四、以資訊電子業上市公司為樣本,探討非優勢公司其資訊移轉效果是否較強烈,以及五、月營收宣告時間的先後是否影響資訊移轉效果。經由實證與分析,本研究得到以下幾點結論: 1.整個資訊電子業、IC製造、印刷電路板、主機板及筆記型電腦產業皆有正向的資訊移轉效果。 2.以好壞消息分組,資訊電子業在市場模式下壞消息組有較強的資訊移轉效果,而IC製造及印刷電路板產業的好消息組有較強的資訊移轉效果。 3.以宣告時點分組,資訊電子業的第一家宣告組具有較強的資訊移轉效果,而在IC製造產業中,第一家宣告組在兩項指數模式下有較弱的資訊移轉效果。 4.優勢公司的資訊移轉效果較弱。 5.檢定移轉效果的同時,亦觀察出行業共同因素與個別公司因素的影響情形,顯示當投資者投資資訊電子業時,其行業指數的漲跌及個別公司的現況皆對其投資決策產生一定程度的影響。

法人說明會資訊對供應鏈上下游公司分析師預測之影響-以我國半導體產業為例 / The effect from up-stream company's conference call information on down-stream company's analysts' forecast-an example from semi-conductor industry in Taiwan

涂智翔 Unknown Date (has links)
法人說明會是公司傳遞內部訊息給外部使用者方法之一,透過法人說明會宣佈財務及非財務資訊,藉以消弭因資訊不對稱所產生之代理問題,亦為分析師作出盈餘預測參考依據之一。在半導體供應鏈中,其上、下游產業間關聯緊密,資訊具有垂直移轉效果,因此,本研究欲探討半導體供應鏈中,下游公司分析師參考上游關聯公司法人說明會資訊並作出盈餘預測調整之程度。 本研究針對國內2005年至2011年半導體上市、櫃公司,進行法人說明會資訊與分析師盈餘預測修正之關聯性。實證結果發現,下游公司財務分析師會參考上游關聯公司召開法人說明會所宣佈之預測財務及非財務資料,並修正對公司之盈餘預測;且供應鏈中,上、下游關係越遠及國籍為外國之分析師,對上游關聯公司法人說明會資訊依賴程度越高,作出的盈餘預測調整幅度越大。

盈餘重編之供應鏈外溢效果 / The Spillover Effects of Earnings Restatements Along the Supply Chain

賴淑妙, Lai, Shu-Miao Unknown Date (has links)
本研究主要探討盈餘重編宣告如何影響重編公司之供應商的股價評價與實質投資決策。首先,本研究假設並發現,盈餘重編宣告除了導致重編公司的股價顯著下跌外,亦誘發其上游供應商的股價顯著下跌。實證進一步發現,供應商的股價依盈餘重編之資訊內涵而調整,促使投資人關注重編事件對上游供應商的預期盈餘之影響,也提醒投資人去關心上游供應商的財務報表品質。其次,本研究假設,盈餘重編宣告傳遞有關重編公司未來前景不佳及財務報表不實的資訊,將影響其供應商對投入特定關係資產所能獲得收益之預期,進而影響其對重編公司所投入的特定關係資產投資決策。實證結果支持前述假說,重編公司之供應商於重編宣告年度後將減少其研究發展支出,且此研究發展支出之變動與重編宣告所引起的股價變動具顯著關聯性。最後本文假設,重編公司扭曲其實際盈餘數字將影響供應商的投資決策,進而影響供應商的投資效率性。研究發現,供應商在重編公司財務報表誤述期間有顯著超額投資之現象。然而,此供應商之超額投資現象在盈餘重編宣告年度後不再顯著。 / This dissertation extends prior research on earnings restatements by examining the effects of earnings restatements on valuation and investment decisions of restating firms’ suppliers. First, this paper hypothesizes and finds that earnings restatements that adversely affect stock price of the restating firms also induce their suppliers’ stock price declines. These stock price declines are related to changes in analysts’ earnings forecasts and seem to reflect investors’ financial reporting quality concerns. Second, I hypothesize that earnings restatements contain information about the value of relationship-specific investments by suppliers. This information causes suppliers to revise their belief about the value of relationship-specific investments, and therefore affects their subsequent relationship-specific investment decisions. Consistent with my prediction, I find that changes in suppliers’ relationship-specific investments after restatement announcements are related to information in the restatements. Finally, I predict and find that a restating firm misreporting financial results induces its suppliers to make excess investments during the misreporting period, while excess investment is no longer positive after the restatement announcement.

法人說明會資訊對供應鏈機構投資人投資行為之影響-以我國半導體產業為例 / The Effect of Up-stream Company’s Conference Call Information on Down-stream’s Company’s institutional investors– An Example From Semi-conductor Industry in Taiwan

劉士豪, Liu, Shih Hao Unknown Date (has links)
本篇研究試圖探討半導體產業供應鏈上游的IC設計業者召開法人說明會後,基於我國半導體產業供應鏈緊密連結之特性,同屬半導體供應鏈的其他中、下游製造和封測廠之機構投資人的交易行為是否將受到IC設計業者宣告之法人說明會資訊影響,亦即證明法人說明會資訊在半導體供應鏈中是否具有垂直資訊移轉效果。實證結果發現在法人說明會召開訊息首次見報日時,供應鏈上游公司之法人說明會訊息確實會影響其中、下游公司之機構投資人的持股變化,於宣告好(壞)消息時買進(賣出),顯示機構投資人藉由其專業團隊和私有資訊能早一般大眾提前調整其交易策略,而此資訊移轉效果也會隨著公司在供應鏈上之距離而逐漸稀釋。此外,結果亦顯示外資由於地緣限制,相較於投信和自營商更會倚賴法人說明會宣告之資訊調整其持股策略,於宣告好(壞)消息時買進(賣出)。 / This research examine the conference call which hold by the IC design companies will transfer useful information to the institutional investors of IC manufacturing and packaging companies in the supply chain downstream. I am interested in if there is a vertical information transfer in the semi-conduct industry. The empirical results show that the conference call information is significantly influence the holding percentage of the institutional investors of the downstream supply chain companies after the information of conference call first reported in the newspapers. The institutional investors will increase the holding percentage after the good news released and vice versa. It is showed that the institutional investors can gather more information before the conference call and adjust their invest strategy in advance. Furthermore, this vertical information transfer effect will dilute by degrees as distance increases. Lastly, the result also shows that the foreign institutional investors more rely on the information released from the conference call to adjust their invest strategy than native institutional investors.

法人說明會資訊對供應鏈上下游公司間股價之影響-以我國半導體產業為例 / The effect from up-stream company’s conference call information on down-stream’s company’s stock price-an example from semi-conductor industry in Taiwan

汪戊安, Wang, Wu An Unknown Date (has links)
本研究主要探討台灣半導體產業供應鏈上游公司召開法人說明會是否會影響中下游公司之股價。本研究將法人說明會公布之資訊區分為財務資訊及非財務資訊,除探討財務資訊對供應鏈中、下游公司股價是否具影響效果外,亦探討財務及非財務的法人說明會資訊是否具有增額效果。實證結果顯示財務資訊在法人說明會召開前後一天與累積異常報酬呈現顯著正向關係,但非財務資訊卻呈現顯著反向關係,顯示非財務資訊會修正財務資訊所造成之效果。另外,資訊於供應鏈中移轉之距離越長,則移轉效果會越小,但若單純為好消息或壞消息,則移轉效果將增強。 / This research examines the influence of conference call information on the stock price of supply chain partners. The semi-conductor industries in Taiwan were used in this paper to examine the issue. I examined two kinds of information disclosed from conference calls: financial information and non-financial information. I first examined the information contained in conference calls for any effects on supply chain partners. Furthermore, I also examined to see if the non-financial information contains any additional effects to the supply chain partners. The empirical results show that the accumulated abnormal return of the supply chain partners is significantly positive related to the financial information around the conference call date. The accumulated abnormal return of the supply chain partners is significantly negative related to the non-financial information around the conference call date. The results show that both financial and non-financial information would influence the accumulated abnormal return of supply chain partners. The non-financial information contains additional information that revises the influence of the financial information.
