Abstract

    This paper examines the underlying motives for distributing stock dividends by firms listed on the Taiwan Stock Exchange. Both survey research and empirical research are employed to investigate the motives for distributing stock dividends. In survey research aspect, we design one questionnaire, which includes two parts, the financial managers' views and the issuing companies' views. Firstly, we design 13 different statements of managers' views about stock dividends, and we find the statement with the highest level of importance was that stock dividends have a positive psychological impact on investors receiving them. The second highest level of importance was that stock dividends convey favorable information about the firm's future prospects. The third one was that shareholders expect stock dividends to continue once initiated. Secondly, we design 8 different statements of companies' views about stock dividends, and we find that the statement with the highest level of importance was to conserve cash in companies. The second highest level of importance was to signal optimistic managerial expectations about the future.

    On the other hand, we conduct empirical research by event studies toward stock dividend announcements for firms listed on the Taiwan Stock Exchange. The research period ranges from 1995 to 1999. We have collected 474 stock dividend announcements after some screening procedures. The market model is employed to examine the announcement effect. In addition to the ordinary least squares model, the GARCH (1,1) model is employed to cope with the serial correlation of volatility. The result shows that stock price reactions are positive and significant around the announcement period of stock dividends. These results support the signaling hypothesis. We also examine stock price reactions around the ex-dividend date. The result shows that the stock price reactions are significantly positive around the ex-dividend period. These results lend supports to the trading range hypothesis, which posits that more investors will trade the stock when the stock price is around the optimal price range.

Finally, we conduct a cross-sectional regression analyses. These analyses are to investigate the relation between the stock dividend percentage and a variety of financial variables. We find several important results. Firstly, ROE has a positive and significant effect toward the stock dividend percentage. These results indicate that stock dividend percentages signal future earnings of the company. Secondly, the ability to issuing stock dividends also has a positive and significant effect. This reflects that companies with higher ratios of retained earnings to equity are more likely to declare higher stock dividend percentages. Thirdly, the stock price of the issuing firm also shows a positive and significant effect, which seems to support the trading range hypothesis. Fourthly, the cumulative mean abnormal return before the announcement period and the cash owned by the issuing firm also have a positive effect. This result supports the optimal trading range hypothesis and cash substitution hypothesis. Finally, the ratio of net change in total assets in the year of stock dividend announcement has a negative effect, indicating that the conserved cash is not necessarily spent on acquiring equipment and machinery.

 

Keywords: Stock Dividends, Information Signaling, Trading Range, Ex-dividend Date.

摘要

    本研究探討台灣股票上市公司發放股票股利的動機,研究方法包括問卷調查與實證研究,在問卷調查方面,我們從兩種不同的觀點來設計問卷,分別針對公司財務主管對於發放股票股利的觀點以及公司本身發放股票股利的動機兩個部份來進行設計,由前者的13個問項中發現到,財務主管認為發放股票股利最重要的因素是讓投資者對公司有正面的心理影響,其次是股票股利的發放能傳達公司對未來展望的好消息,再其次則是股東希望公司能夠維持發放股票股利的傳統;另外,在公司本身對於發放股票股利的8個動機上,最主要的動機是為了能夠保留現金在公司內部,其次則是為了傳達管理階層對公司未來遠景樂觀預期的訊息。

    在實證研究上,我們採用事件研究法來進行股票股利宣告與除權的分析,同時為了調整市場模式具有異質變異數的現象,本研究加入了GARCH(1,1)模式來進行參數的估計,並與OLS結果相對照,結果發現到股價在宣告期間與除權期間皆具有顯著的正異常報酬;另外,在對除權日前後成交量的變化上,亦發現在各種時間區間下皆呈現成交量顯著增加的現象,以上結果則分別支持訊息傳遞假說與最適價格區間假說。

    最後,我們建立一橫斷面的迴歸分析,用來檢測配股率和公司財務變數間的關係,我們得到了幾個重要的發現,首先,由於權益報酬率、公司配股能力對於配股率有正向且顯著的影響,表示公司會以較高的配股率來傳達有關未來盈餘高低的訊息;而公司有較高的配股能力時,也會傾向配發較高的股利,此項結果支持訊息傳遞假說,推論公司發放股票股利具有傳遞訊息的動機,藉著配股率的高低來傳達有關公司未來盈餘的訊息。其次,宣告日前一個月的股票均價其係數顯著為正,表示股價越高配股率也越高,同時由迴歸式中可觀察到宣告前的累積異常報酬率其係數也為顯著為正,因此,可以得知股票在宣告日前有正的累積異常報酬,且股價越高,其配股率也越高,推論公司似乎會藉由股票股利調整股價到合適的交易範圍。另外,由於公司內部現金的多寡和配股率呈現顯著正方向的變動,顯示前一年年底保留在公司內的現金越多,其配股率越高,支持現金替代假說;再者,由發放股票股利當年的資產變動和配股率成反向關係,推論公司會藉由發放股票股利保留現金在公司內,但並不一定會用來作為擴充資產之用。
