This study examines how market timing can affect host market reaction to cross-border seasoned equity offerings (SEOs), an event generally viewed unfavorably by investors. We assume that firms engage in market timing in response to valuation uncertainty (VU), home market uncertainty (HMU) and/or host market uncertainty (HSU), and that raising capital abroad faces higher scrutiny costs and familiarity bias from host market investors. We conjecture that timing strategies provide signals that vary in strength to host market investors and that dual-timing strategies may strengthen an existing signal. Our hypotheses are tested on a sample of 190 cross-border SEOs that were issued on the U.S. stock market between 1990 and 2017 by firms from 29 countries. Using event study methodology, we find that market timing based on VU is negatively related to host market valuation and that a dual-timing strategy with HMU or HSU generally produces a stronger signal. Our results have practical relevance for stock markets that suffer from high uncertainty; we estimate that a high VU firm with a $1 billion valuation suffers a drop of $31.3 million in market valuation during a high host market uncertainty (high HSU) compared with low host market uncertainty (low HSU).  相似文献

We argue that when individuals care about their consumption relative to that of their neighbours, a home bias emerges, that is investors overweight domestic stocks in their portfolios. Domestic stocks are preferred because they also serve the objective of mimicking the economic fortunes and welfare of the investor's neighbours, countrymen, and social reference group. We also demonstrate that globalization mitigates the home bias, and derive a modified international CAPM.  相似文献

This paper investigates whether familiarity induced by ambiguity aversion can help explaining the local bias phenomenon among individual investors. Using geographic closeness as a proxy for investor familiarity, we find that investors pull out of (unfamiliar) remote stocks and pour into (familiar) local stocks during times of increased market uncertainty. Moreover, the magnitude of this ‘flight to familiarity’ increases in the spread of an investor's ambiguity (about expected returns) between local and remote stocks. Our results prove robust to a number of alternative explanations of local bias. Specifically, we rule out a ‘home-field advantage’, where investors are able to translate information advantages about nearby companies into excess returns on their local stockholdings. We conclude that individual investors’ local bias is induced by ambiguity aversion in the portfolio selection process rather than a trading strategy based on superior information about local companies.  相似文献

We examine the familiarity hypothesis of home bias by studying how foreign ownership of Swedish firms is affected by the mandatory adoption of IFRS. We decompose foreign investors into institutional and non-institutional investors. Foreign investors are further decomposed into EU (IFRS adopting countries) and non-EU residents (non-IFRS adopting countries). We analyse the equity investments of these foreign investor groups in Sweden during the period of 2001–2007. We find that after the mandatory adoption of IFRS, foreign ownership/owners from countries that adopted IFRS and particularly those from the EU increased. These effects are particularly strong in small firms. Foreign institutional investors increased their ownership stake after the mandatory IFRS adoption, whereas foreign non-institutional investments were not affected significantly by the IFRS adoption. In contrast to ownership from non-adopting countries, ownership from the EU increased in firms with both more and less tangible assets. Similarly, foreign ownership from the EU increased in firms with both concentrated ownership and dispersed ownership after the adoption. Because Sweden has already had strict legal enforcement and a low level of earnings management prior to the adoption, our results suggest that increased foreign ownership is due to better abilities to compare firms rather than an improved quality.  相似文献

Prior studies show that the beta coefficient of a security changes systematically as the length of measurement interval is varied. This phenomenon, which is called the intervalling effect bias in beta, has been attributed to the friction in the trading system that causes the delays in the price-adjustment process. This study shows that option listing is associated with a decline in the beta intervalling effect bias. The decline is most pronounced for small firms. We also find that our sample firms grow significantly after option listing. Since prior research indicates that market value is a major determinant of the magnitude of the intervalling effect, we re-examine our results using a subsample that controls for market value. The results indicate that the decline in the beta bias from the pre-listing to post-listing period is still prevalent after we control for the change in firm size. Overall, the evidence is consistent with the notion that option trading reduces the delays in the price-adjustment process, which in turn reduces the intervalling effect bias in beta.  相似文献

"工薪族"已经成为我国商业银行重要的理财细分市场客户群体。为分析我国"工薪族"客户金融投资理财行为和投资理财需求差异,以河南省8个市县地区为样本,采用分层随机抽样法选取近2 000名"工薪族"理财客户进行了问卷调查。调查结果表明:绝大多数"工薪族"属于风险厌恶型投资者,偏好风险较低的金融资产;但是,"工薪族"的负债比例却较高且集中在房屋和汽车等方面;中高收入地区"工薪族"更偏好理财产品,而低收入地区"工薪族"更偏好银行储蓄;低收入地区"工薪族"在投资理财时存在更为明显的从众行为。  相似文献

This study empirically tests whether foreign investors take advantage of international diversification when investing in emerging Asian markets. Using the 2007–2008 financial crisis as identification, we find that firms with higher foreign ownership had better stock returns during the financial crisis. Moreover, the diversification effect exists in five out of the eight emerging markets and is stronger in markets with a lower dynamic conditional correlation with the global market index. We also find that foreign investors prefer firms with a lower international sales ratio. In conclusion, the evidence consistently suggests that foreign investors take advantage of diversification effects.  相似文献

The extant literature on behavioral corporate finance has explored the effects of overconfidence on investment–cash flow sensitivity (ICS) to explain overinvestment, yet it has overlooked the asymmetric behavior of investments in relation to changes in cash flow levels. This study examines whether investments behave asymmetrically responding to changes in cash flows and, if so, how managerial overconfidence affects asymmetric ICS. Using a sample of KOSPI and KOSDAQ firms in Korea, we find the incidence of downwardly sticky ICS in unconstrained firms. We then find that overconfident managers encourage ICS to be stickier than their rational peers do in unconstrained firms. Finally, we find that managerial overconfidence intensified by self-attribution bias induces ICS to get even stickier, suggesting more explicit evidence of corporate investment distortions. The results of alternative tests using the asymmetric models of Homburg and Nasev (2008) are qualitatively consistent with prior results. Overall, our findings imply a higher incidence of excessive investment commitments driven by overconfident managers.  相似文献

Corporate social performance (CSP) consists of actions in different domains that vary in the information they provide stakeholders, and hence, in their effect on firm performance. To demonstrate this, the authors examine the impact of CSP on firm performance in two areas—the product and the environment, referred to as product social performance (PSP) and environmental social performance (ESP), respectively. PSP has a stronger positive impact on firm performance compared to ESP. The findings using disaggregated measures of PSP and ESP indicate negativity bias in that PSP weakness has a stronger negative impact on firm performance compared to PSP strength.

Prior research has documented a finding that local analysts provide more accurate earnings forecasts than nonlocal analysts in many settings. However, little is known about local and nonlocal analysts’ relative earnings forecast abilities for ADR stocks. In this study, we find that the local advantage disappears for ADR stocks and that nonlocal analysts in fact outperform local ones in this case. We investigate the source of this ‘local disadvantage’ and find evidence against hypotheses based on accounting standards and exchange rates. We document that the local advantage decreases with increased investor interest in foreign firms, consistent with our nonlocal investors’ interest hypothesis.  相似文献
