A multilateral approach to examining the comovements among major world equity markets

This study investigates the comovement in stock indices among major developed markets, where Morgan Stanley Capital International (MSCI) indices are employed for the purposes of the study. We employ a model that accommodates multilateral international impacts on equity index movements. The empirical results reveal the existence of significant international transmission effects among these major world markets, both in terms of returns and volatility, and mostly in a positive direction. The U.S. market, as expected, is the leading market in the sense that it has the most pervasive and significant impact on all markets across continents. However, the U.S. market exhibits a different relationship with European markets from that with Asia-Pacific markets. The evidence also suggests that strong regional transmission effects exist. A further investigation using the extended model reveals that the linkages between U.S. and European markets are driven by positive global common forces and by negative international competitive effects. On the other hand, the U.S. and Asian markets are linked through positive global common forces and positive international contagion effects. The United States, Canada, and the U.K. are the three markets that still demonstrate contagion influence over countries outside its own region. The Asia-Pacific markets are more susceptible to contagion effects. Finally, it is interesting to find that Japanese market performance became more contagious toward other markets during the Asian financial crisis period.     

Asia-Pacific Stock Market Integration: New Evidence by Incorporating Regime Changes

ABSTRACT

This work provides new evidence of Asia-Pacific stock market integration by incorporating the regime changes of each stock market through the smooth transition autoregressive (STAR) model. According to empirical results, most Asia-Pacific stock market returns follow STAR dynamics to a significant degree with more rapid and frequent regime changes of a shorter nature compared with G7 markets. A series of STAR-based Granger causality tests reveal evidence of stronger equity market integration compared with linear Granger causality tests. We also find that Asia-Pacific stock markets are integrated in different levels. Finally, we provide evidence that in the early twenty-first century the influence of China and the United States on Asia-Pacific stock markets has been maintained while that of Japan has been weakened.     

The spillover effects of target interest rate news from the U.S. Fed and the European Central Bank on the Asia-Pacific stock markets

This paper provides comprehensive evidence on the spillover effects of the U.S. Fed's and the European Central Bank (ECB)’s target interest rate news on the market returns and return volatilities of 12 stock markets in the Asia-Pacific over the period 1999–2006. The news spillover effects on the returns are generally consistent with the literature where a majority of stock markets shows significant negative returns in response to unexpected rate rises. While the results of the speed of adjustment for the Fed's news are mixed across the markets, the ECB news was absorbed slowly, in general. The return volatilities were higher in response to the interest rate news from both sources. In addition, both the Fed and the ECB news elicited tardy or persisting volatility responses. These findings have important implications for all levels of market participants in the Asia-Pacific stock markets.     

MEAN AND VOLATILITY SPILLOVERS ACROSS MAJOR NATIONAL STOCK MARKETS: FURTHER EMPIRICAL EVIDENCE

This paper provides additional insight into the nature and degree of interdependence of stock markets of the United States, Japan, the United Kingdom, Canada, and Germany, and it reports the extent to which volatility in these markets influences expected returns. The analysis uses the multivariate GARCH-M model. Although they are considered weak, statistically significant mean spillovers radiate from stock markets of the U.S. to the U.K., Canada, and Germany, and then from the stock markets of Japan to Germany. No relation is found between conditional market volatility and expected returns. Strong time-varying conditional volatility exists in the return series of all markets. The own-volatility spillovers in the U.K. and Canadian markets are insignificant, supporting the view that conditional volatility of returns in these markets is “imported” from abroad, specifically from the U.S. Significant volatility spillovers radiate from the U.S. stock market to all four stock markets, from the U.K. stock market to the Canadian stock market, and from the German stock market to the Japanese stock market. The results are robust and no changes occur in the correlation structure of returns over time.     

Global financial crisis and emerging stock market contagion: A volatility impulse response function approach

By employing the volatility impulse response (VIRF) approach, this paper presents a general framework for addressing the extent of contagion effects between the BRICSs’ and U.S. stock markets and how the BRICSs’ stock markets have been influenced in the context of the 2007–2009 global financial crisis. Our empirical results show during the period of 2007–2009 global financial crisis, there are significant contagion effects from the U.S. to the BRICSs’ stock markets. Yet, the degree of stock market reactions to such shocks differs from one market to another, depending on the level of integration with the international economy. Besides, the strengthened degree of stock market integration among the U.S. and BRICS has adverse effect such that if the 2007–2009 global financial crisis occurs today it may result in heavier impact on stock market volatility nowadays compared to the crisis-era.     

Spreading the fear: The central role of CBOE VIX in global stock market uncertainty

Construction of efficient portfolios is reliant on understanding the correlation between assets. If correlations change markedly during times of economic turmoil then investors are exposed to greater risk at the most inopportune time. We examine the linkages between global stock markets using measures of market uncertainty (implied volatility). Using a sample of daily changes in G7 and BRIC implied volatility measures, over a 20-year sample period, we demonstrate that uncertainty in U.S. markets plays a pivotal role in global stock market uncertainty. “Fear is spread” across markets, as heightened uncertainty in U.S. markets is transmitted across global markets. Conversely, changes in global market uncertainty do not explain changes in U.S. market uncertainty. While there is a clear increase in connectedness during crisis periods, we observe a disparity in the way that inter-dependencies change during the two major economic crises in our sample period; the GFC (2007–2009) and COVID-pandemic (2020). The additional importance of US news largely drives our results during the GFC, while the effect is spread among several countries (particularly within European markets) during COVID.     

Investors’ risk perceptions in the US and global stock market integration

Investors’ risk perceptions have significant implications for international stock markets. This paper estimates the time-varying impact of the VIX index – a widely used measure of investors risk perceptions – on the dynamic correlation across international stock markets. Results show that risk perceptions significantly impact the dynamic correlation between the U.S. market and the leading stock markets of the world. Further, in 17 out of 20 international stock markets, risk perceptions Granger cause dynamic correlations. The impact of VIX is positive on the correlation of the U.S. market with European and Latin American markets. In contrast, the relationship of the U.S. market with all the Asian markets weakens (strengthens) as the VIX index rises (falls). In all cases, the time-varying parameter model shows that the impact of VIX on these correlations varies significantly across time.     

Legality and venture capital exits

This paper introduces an analysis of the impact of Legality on the exiting of venture capital investments. We consider a sample of 468 venture-backed companies from 12 Asia-Pacific countries, and these countries' venture capitalists' investments in US-based entrepreneurial firms. The data indicate IPOs are more likely in countries with a higher Legality index. This core result is robust to controls for country-specific stock market capitalization, MSCI market conditions, venture capitalist fund manager skill and fund characteristics, and entrepreneurial firm and transaction characteristics. Although Black and Gilson (1998) [Black, B.S., Gilson, R.J., 1998. Venture capital and the structure of capital markets: banks versus stock markets. Journal of Financial Economics 47, 243–77] speculate on a central connection between active stock markets and active venture capital markets, our data in fact indicate the quality of a country's legal system is much more directly connected to facilitating VC-backed IPO exits than the size of a country's stock market. The data indicate Legality is a central mechanism which mitigates agency problems between outside shareholders and entrepreneurs, thereby fostering the mutual development of IPO markets and venture capital markets.     

Factors affecting the yields of emerging market issuers: Evidence from the Asia-Pacific region

We investigate the yield spread between the sovereign bonds issued in international markets by major Asia-Pacific issuers (China, Korea, Malaysia, Philippines and Thailand) and matched with near maturity benchmark U.S. Treasury bonds (2, 5, 10 year maturities) to determine the extent that various factors affect changes in credit spreads. The results suggest that the credit spreads of these sovereign bonds tend to be negatively related to changes in interest rates on U.S. benchmark bonds and positively related to changes in the slope of the yield curve. The asset and exchange rate variables were only significant for spreads on Philippine bonds where it was negatively related to changes in the local stock market index, and positively to changes in the exchange rate. The complex dynamics of these processes highlight concerns for portfolio mangers when constructing portfolios of sovereign Asian bonds by aggregating bonds of different credit ratings.     

Capital market consequences of cultural influences on earnings: The case of cross-listed firms in the U.S. stock market

We examine whether market reactions to earnings announcements vary according to differences in the cultural values of firms' countries of origin in the case of cross-listed firms in the U.S. stock market. To deal with time-varying volatility returns, market reactions are determined using the market model adjusted for GARCH. We also apply the Fama-French three factor model to determine market reactions. Using the dynamic panel generalized method of moments estimator, we analyze 5562 firm-year observations from 30 countries over the period 2000–2014. We find that market reactions to the earnings announcements of cross-listed firms are significantly negatively (positively) associated with firms’ home countries characterized by the culturally- based accounting values of conservatism (optimism) and secrecy (transparency). Overall, the results suggest that the informal institutional influences of culture relating to the financial performance of cross-listed firms are priced by the U.S. stock market.     

Impact of Earnings,Dividends and Cash Flows on Stock Returns: Case of Taiwan's Stock Market

The study uses Taiwan's stock market, a newly developed market with different characteristics from that of the U.S., as an experimental case to examine the influences of the market's characteristics on the relationship between stock returns and fundamental accounting information, such as earnings, dividends and cash flows. The testing period is from 1990 to 1994, right after the promulgation of Taiwan's accounting standard for statement of cash flows in 1989.Similar to the findings of U.S. studies, the study shows that earnings data is key information for investors. Unlike the U.S. results, however, both operating income and non-operating income are positively related to stock returns. The usefulness of non-operating income to explain stock returns is due mainly to its recurrent characteristic in Taiwan. The market views non-operating income, mostly from disposal of real-estate and short-term equity investments, as a complementary factor to operating income. It is a possible common phenomenon in a booming economy. Unlike from the results of U.S. studies, Taiwan's stock returns are strongly associated with stock dividends. Cash dividends, however, are relatively less important information to the market. The fast booming economy as well as Taiwan's free tax rate on capital gains are the explanations for the different findings. The results also support McNicholes and Dravid's (1990) and etc. results that stock dividends may act as a signal for favorable future earnings. Examining the association between stock returns and cash flow information, the results indicate that stock returns are positively associated with cash flows from both operating and financing activities. The phenomenon implies that the market appreciates not only the cash inflows from operating activities, but also cash inflows from new issues of bonds or stocks for further expansion. It is consistent to Taiwan's booming economy. The finding also supports Ross (1977) and Leland and Pyles' (1977) signaling hypothesis.The study concludes that the relationships between stock returns and fundamental variables are subject to the market's characteristics. The case of the Taiwan stock market shows that usefulness of accounting information depends upon the different roles of the information in the tested market. The results of the study also indicate that directly applying the U.S. experiences without any adjustment may cause incorrect conclusions for empirical studies.     

A comprehensive investigation on the predictive power of economic policy uncertainty from non-U.S. countries for U.S. stock market returns

This study uses economic policy uncertainty (EPU) indices for ten developed countries, three diffusion models, and five combination methods to forecast excess returns in the U.S. stock market. It shows empirically that, over the period January 1997 to January 2022, non-U.S. EPU indices have better predictive power for U.S. equity market excess returns than the U.S. EPU index itself. This illustrates how economic information from international markets can affect the U.S. stock market. This finding challenges the extensively recognized view that the U.S. is where important market signals are initially transmitted to other markets, suggesting that this belief is incomplete. Our outcomes are robust to a battery of tests covering model selection, model specification, forecast horizons, and the pandemic period, and their economic values are assessed. The findings are essential for the financial field to confront future fierce situations and crises.     

An empirical investigation of Yankee stock offerings

This paper examines the operating and investment performance of 100 foreign firms that conduct their initial public offerings (IPOs) in the U.S. (Yankee stock offerings). The uniqueness of these firms is that the U.S. IPOs are their first public equity issue in any market, including the home market. We find significant improvement in the operating performance subsequent to these U.S. IPO events and firms from countries with poor investor protection benefit more. Compared to various benchmarks, unlike the significant underperformance of IPOs documented in many countries, these firms show no significant abnormal long-run stock market performance after 1, 3, or 5 years of seasoning. The findings are consistent with signaling and selective entry hypotheses.     

Co-movement of Asia-Pacific with European and US stock market returns: A cross-time-frequency analysis

We investigate the co-movement of 13 Asia-Pacific stock market returns with that of European and US stock market returns using the wavelet coherence method. Our results show consistent co-movement between most of the Asia-Pacific stock markets and that of Europe and the US in the long run. We also uncover evidence of a wide variation in co-movement across the time scale of the financial crises. The co-movement dynamics of the Asia-Pacific markets with that of Europe and the US are different during the two financial crises. The difference in the co-movement dynamics could be the result of the different natures of the financial crises or a change in regime.     

Realizing the volatility impacts of sovereign credit ratings information on equity and currency markets: Evidence from the Asian Financial Crisis

We examine the effects of different types of sovereign rating announcements on realized stock and currency market volatilities and cross-asset correlations around periods of financial crises. Using intraday market data and sovereign ratings data for nine sample countries in the Asia-Pacific region over 1997–2001, we find that currency and stock markets react somewhat heterogeneously to various rating announcements and that stock markets are more responsive to rating news than currency markets. We find new evidence that ratings events have significant and asymmetric impacts on intraday market data and that national market attributes influence rating impacts during financial crises.

Timescale-dependent stock market comovement: BRICs vs. developed markets

This paper examines the differences in the asset return comovement of the BRIC countries (Brazil, Russia, India and China), the other developed economies in their regions (Canada, Hong Kong and Australia) and the major industrialized economies (the U.K., Germany and Japan) with respect to the U.S. for different return periods. The novelty of the paper is that the stock return indices are decomposed to several timescales using wavelet analysis and that the results are further used as inputs for the dynamic conditional correlation (DCC) framework, which is used as a measure of comovement. The results propose that the level of stock market comovement depends on regional aspects, the level of development and especially on the timescale of returns. These factors should be carefully considered in designing internationally diversified portfolios. The BRICs provide some portfolio diversification benefits, but it is not justifiable to treat all BRICs as a homogeneous group of emerging economies in terms of stock market comovement.     

The Risk‐Return Relation in International Stock Markets

We investigate the risk‐return relation in international stock markets using realized variance constructed from MSCI (Morgan Stanley Capital International) daily stock price indices. In contrast with the capital asset pricing model, realized variance by itself provides negligible information about future excess stock market returns; however, we uncover a positive and significant risk‐return tradeoff in many countries after controlling for the (U.S.) consumption‐wealth ratio. U.S. realized variance is also significantly related to future international stock market returns; more importantly, it always subsumes the information content of its local counterparts. Our results indicate that stock market variance is an important determinant of the equity premium.     

Investor sentiment and stock returns: Some international evidence

We examine whether consumer confidence – as a proxy for individual investor sentiment – affects expected stock returns internationally in 18 industrialized countries. In line with recent evidence for the U.S., we find that sentiment negatively forecasts aggregate stock market returns on average across countries. When sentiment is high, future stock returns tend to be lower and vice versa. This relation also holds for returns of value stocks, growth stocks, small stocks, and for different forecasting horizons. Finally, we employ a cross-sectional perspective and provide evidence that the impact of sentiment on stock returns is higher for countries which have less market integrity and which are culturally more prone to herd-like behavior and overreaction.     

Is VIX an investor fear gauge in BRIC equity markets?

This study examines the intertemporal relationships between CBOE market volatility index (VIX) and stock market returns in Brazil, Russia, India, and China (BRIC), and between VIX and U.S. stock market returns, to uncover if VIX serves as an investor fear gauge in BRIC and U.S. markets. We conduct the VIX-returns analysis for the 1993–2007 period.Our results suggest a strong negative contemporaneous relation between daily changes (innovations) in VIX and U.S. stock market returns. This relation is stronger when VIX is higher and more volatile. A significant negative contemporaneous relation between VIX and equity returns also exists for China and Brazil during 1993–2007 and for India during 1993–1997. Similar to the U.S. market, the immediate negative relation between the Brazilian stock returns and VIX changes is much stronger when VIX is both high and more volatile. Our results also indicate a strong asymmetric relation between innovations in VIX and daily stock market returns in U.S., Brazil, and China, suggesting that VIX is more of a gauge of investor fear than investor positive sentiment. However, the asymmetric relationship between stock market returns and VIX is much weaker when VIX is large and more volatile. These results have potential implications for portfolio diversification and for stock market and option trading timing in the equity markets of Brazil, India, and China. Overall, our results indicate that VIX is not only an investor fear gauge for the U.S. stock market but also for the equity markets of China, Brazil, and India.
