Intraday return spillovers and its variations across trading sessions

The main purpose of this paper is to study the intraday return spillovers and their real time variations amongst selected technology stocks. Based upon randomly selected technology stocks in terms of multilateral analysis, we find the following evidence. Firstly, we find that positive spillover effects are discernible amongst medium- and large-sized stocks, with the effects being directionally asymmetric between different size groups. Secondly, we find that for most stocks, the full effects of the firm-specific shocks over other stocks are realized within approximately 30 min to 2 h. Finally, we show that the spillover effects tend to follow an M-shaped intraday pattern. Our results suggest that during the opening and closing sessions, trades motivated by information spilled over from other firms are relatively subordinated, with the trading at these times being largely dominated by those based upon common market factor or firm-specific fundamental information.     

Does prior record matter in the wealth effect of open-market share repurchase announcements?

This study investigates whether prior experience of share repurchases matters in the market reactions to the subsequent repurchase announcements. Specifically, we study the prior record on actual buybacks and post-announcement stock performance. We find that upon the announcement of share repurchases, stock markets not only respond more positively to those made by firms that have better record on actual buyback following their previous repurchase plan announcements, but also experience a stronger reaction for announcing firms with better stock performance after prior repurchase announcements. These results hold even after controlling for other variables that are found important in influencing the market reactions to repurchase announcements.     

Are Expected Inflation Rates and Expected Real Rates Negatively Correlated? A Long‐Run Test of the Mundell‐Tobin Hypothesis

Some empirical evidence suggests that the expected real interest and expected inflation rates are negatively correlated. This hypothesis of negative correlation is sometimes known as the Mundell‐Tobin hypothesis. In this article we reinvestigate this negative relation from a long‐term point of view using cointegration analysis. The data on the historical interest rate on T‐bills and the inflation rate indicate that the Mundell‐Tobin hypothesis does not hold in the long run for the United States, the United Kingdom, and Canada. We also obtain similar results using the real interest rate on index‐linked gilt traded in the United Kingdom.     

The Wealth Effect of Domestic Joint Ventures: Evidence from Taiwan

This study presents important international evidence by examining the wealth effect of domestic joint ventures by Taiwanese firms. In opposite to United States evidence, we find that announcements of domestic joint ventures by Taiwanese firms are, on average, associated with significantly negative abnormal stock returns. We also find that the stock market response to announced domestic joint ventures is significantly positively related to the announcing firms' investment opportunities, size of investment and debt ratio, and is significantly negatively related to the business relatedness variable. In contrast, free cash flow, firm size, relative firm size and managerial ownership are found to have no significant power in explaining the market response. Our results support the investment opportunities, synergy and complementarity hypotheses as well as a broad interpretation of the free cash flow hypothesis, but reject the absolute size, relative size and alignment-of-interests hypotheses. This study makes valuable contributions to the literature by providing the first direct evidence on the role of investment opportunities, synergy and alignment-of-interests in explaining the wealth effect of domestic joint ventures     

The effects of executive compensation and outside monitoring on firms’ pre-repurchase disclosure behavior and post-repurchase performance

Corporate governance and capital allocations of diversified firms

We examine how various aspects of corporate governance structures affect the capital allocation inefficiency that drives the value discounts of diversified firms. Diversified firms with more effective internal or external governance mechanisms experience more efficient investment allocations at both the firm and segment levels and show less of a diversification discount. The efficiency of the investment allocation process is better for diversified firms with high board independence, low board busyness, high institutional ownership, high outside director ownership, high CEO equity-based pay, high audit quality, and strong shareholder rights. The results hold after controlling for other potential influences. Our evidence suggests that corporate governance considerations are important in assessing the relation between investment efficiency and firm value for diversified firms.     

Earnings Management and the Long-Run Underperformance of Firms Following Convertible Bond Offers

Abstract:  This paper examines whether the long-run underperformance of convertible bond issuers can be explained by earnings management, as reflected in discretionary current accruals around the time of the offer. Consistent with the earnings management hypothesis, we find that convertible issuers who adjust their discretionary current accruals to report higher net income in the issue year will generally experience inferior operating and stock return performance over the five-year post-issue period. Our findings indicate that there is some temporary overvaluation of convertible issuers by the stock market, but that the resultant disappointed investors will subsequently correct their valuation errors. The similarity of our results to those reported within the prior literature on initial public offers (IPOs) and seasoned equity offers (SEOs) suggests that the earnings management hypothesis is not unique to stock offers, but that it actually extends to convertible bond offers.     

Weather and intraday patterns in stock returns and trading activity

We examine the relation between weather in New York City and intraday returns and trading patterns of NYSE stocks. While stock returns are found to be generally lower on cloudier days, cloud cover has a significant influence on stock returns only at the market open. There are significantly more seller-initiated trades when there is more cloud cover at the market open, which is consistent with the return results. Cloudy skies are associated with higher volatility and less market depth over the entire trading day. Finally, cloud cover is not significantly correlated with spread measures and turnover ratios. The findings overall suggest that weather has a significant influence on investors’ intraday trading behavior.     

Investment Opportunities,Free Cash Flow and Stock Valuation Effects of Corporate Investments: The Case of Taiwanese Investments in China

This paper examines the importance of investment opportunities and free cash flow in assessing the stock market reaction to announcements of cross-border investments in China by Taiwanese firms. Our results support the investment opportunities hypothesis that Taiwanese firms with favorable investment opportunities have significantly positive response to the announcements of their investments in China whereas firms with poor investment opportunities have negative response to such announcements. In contrast, we find no support for the free cash flow hypothesis. Our findings add to the understanding of the determinants of the wealth effect of cross-border investment decisions in the Asia-Pacific region.     

Wealth Effects of Private Equity Placements: Evidence from Singapore

We examine institutional characteristics and the wealth effects of private equity placements in Singapore. Our findings show that private placements in Singapore generally result in a negative wealth effect and a reduction in ownership concentration. We find that at high levels of ownership concentration, the relation between abnormal returns and changes in ownership concentration is significantly negative. We also show that the market reacts less favorably to placements in which management ownership falls below 50%, but more favorably to issues to single investors. We do not find evidence suggesting that our results are due to an information effect.
