Price discovery of cross-listed firms

This paper examines the contribution of cross-listing to price discovery for a unique and comprehensive sample of firms listed abroad. Using an extended measure of the common factor weight, we find that foreign market contribution to price discovery is more important for multiple-listed firms compared to cross-listed ones. Our results also show that US exchanges are more conductive to price discovery than do foreign European markets. On a univariate regression, we find new evidence that order driven markets and those which are more integrated with the world contribute significantly to price discovery of stocks listed abroad. On a multivariate regression, information asymmetry measures seem to have the most important effect on foreign market contribution to price determination.     

Ripples through markets: Inter-market impacts generated by large trades

This paper uses a sample of large trades executed on the London Stock Exchange's SEAQ-I market for European cross-traded firms to investigate their impact on home market prices when parallel markets suffer from information frictions. I find that (a) large London trades produce price impacts in home markets even though no timely information is published, (b) market makers appear to pre- and post-position their inventories by splitting orders across markets, and (c) the price discovery process across markets changes significantly around large trades with the foreign market making a significantly bigger contribution to price discovery at this time, even though information opaqueness exists.     

Do foreigners facilitate information transmission in emerging markets?

Using the degree of accessibility of foreign investors to emerging stock markets, or investibility, as a proxy for the extent of foreign investments, we assess whether investibility has a significant influence on the diffusion of global market information across stocks in emerging markets. We show that greater investibility reduces price delay to global market information. We also find that returns of highly investible stocks lead those of noninvestible stocks because they incorporate global information more quickly. These results are consistent with the idea that financial liberalization in the form of greater investibility yields informationally more efficient stock prices in emerging markets.     

Price Interactions in a Sequential Global Market: Evidence from the Cross-listed Stocks

In this paper, we investigate the pattern of dynamic interactions among the prices of those stocks that are cross-listed on the three major stock markets of the world, i.e. New York, London and Tokyo. Major findings are: first, regardless of the nationality of stocks, innovations in the 'home' market returns are always fed into the returns in the 'overseas' markets, with the former causing the latter in the Granger sense. However, innovations in the New York market returns of foreign stocks are fed back into their respective home markets, contributing to the price discovery there. Second, the 'succeeding' overseas market, which operates immediately after the home market, plays a dual-role: it conducts the home market innovations to the next-opening overseas market, as well as adds its own innovations. Third, the exchange rate changes substantially influence the overseas market returns, but not the home market returns. The exchange rates appear to play a role in the transmission mechanism mainly via the inter-market price parity.     

The Effect of Political Uprisings on the Location of Price Discovery: Evidence from Egyptian Cross-Listed Equities

In this study, we aim to determine the location of price discovery for Egyptian cross-listed stocks around the political uprising that started on January 25, 2011, and resulted in a two-month stock market closure. We measure price discovery using Gonzalo and Granger's component share and Hasbrouck's information shares and find that, for some stocks, the contribution of the foreign market in pricing cross-listed equities increases in the period directly following the reopening of the Egyptian stock market. We discuss the factors that could explain the more pronounced shifts in the location of price discovery for some companies in the post-uprising period.     

The informativeness of domestic and foreign investors’ stock trades: Evidence from the perfectly segmented Chinese market

This paper uses the perfect market segmentation setting in China's stock market to compare the information content of the stock trades of domestic and foreign investors. We study 76 firms that issue both A-shares (for domestic investors) and B-shares (for foreign investors) and compare the price discovery role of the two segmented markets in China. Before Feb 19, 2001, the A-share market led the B-share market in price discovery, as the signed volume and quote revision of the A-share market had strong predictive ability for B-share quote returns, but not vice versa. After Feb 19, 2001, because some domestic investors were allowed to invest in the B-share market, we find evidence for a reverse causality from the B-share to the A-share market. Nevertheless, the [Hasbrouck (1995). One security, many markets: determining the contributions to price discovery, Journal of Finance 50, 1175–1199.] information share analysis reveals that A-shares continue to dominate the price discovery process.     

Do foreign investors improve stock price informativeness in emerging equity markets? Evidence from Vietnam

Most of previous studies on stock price informativeness tend to focus on the context of mature stock markets while this issue is more acute in emerging equity markets where regulatory and institutional structure are weak. This paper examines the relationship between foreign ownership and stock price informativeness in Vietnam stock market. We utilize a data set covering firm attributes of non-financial firms listed on the Ho Chi Minh City stock exchange over the period 2007–2015. Employing different estimation techniques for panel data, the empirical results indicate that foreign investors improve stock price informativeness in Vietnam stock market. The finding from this paper confirms the important role of foreign investors in emerging equity markets.     

Foreign Institutional Investment,Ownership, and Liquidity: Real and Informational Frictions

The literature widely documents the negative liquidity impact of foreign participation in firms that permit high foreign institutional ownership. This paper employs a unique setting for the limited participation of qualified foreign institutional investors (QFIIs) in China's A-share market and examines how this impacts on stock liquidity in emerging markets. Contrary to the findings in the literature, foreign investor participation helps enhance the liquidity of affected stocks by promoting trade activities and price discovery. The improvement in liquidity does not occur through the information friction channel, but rather the real friction channel. Our results are robust to endogeneity issue and the possible influence of the global financial crisis, industry effects and the stock exchange. Further, the liquidity improving effects of QFII are even stronger when the analysis is performed on a subsample of QFII firms.     

FOREIGN OWNERSHIP RESTRICTIONS AND MARKET SEGMENTATION IN CHINA'S STOCK MARKETS

We study market segmentation in China's stock markets, in which local firms issue two classes of shares: class A shares available only to Chinese citizens and class B shares available only to foreign citizens. Significant stock price discounts are documented for class B shares. We find that the price difference is primarily due to illiquid B‐share markets. Relatively illiquid B‐share stocks have a higher expected return and are priced lower to compensate investors for increased trading costs. However, between the two classes of shares, B‐share prices tend to move more closely with market fundamentals than do A‐share prices. Therefore, we find A‐share premiums rather than B‐share discounts in China's markets. JEL classification: G15     

Asset pricing in China's domestic stock markets: Is there a logic?

China's stock markets have grown rapidly since their inception and have become an increasingly important emerging market for international investors. However, there are few systematic studies on how asset prices are formed in Chinese domestic equity markets; popular financial media even depict the market as irrational. In this paper, we study the asset pricing mechanism in the nascent Chinese stock markets, with the objective of identifying variables that capture the cross-sectional variation in average stock returns. We focus on the effects of various market imperfections in China. We find that while the market risk (beta) is not priced, there is a significantly negative relationship between firm-specific risk and expected returns. Chinese investors are willing to pay a significant premium for more liquid stocks or for dividend-paying stocks. Furthermore, investors value local A-shares more if there are offshore counterparts (e.g., B- and H-shares) for foreigners, implying that a Chinese firm with a foreign shareholder base has a lower cost of capital, ceteris paribus. Lastly, as with U.S. and other mature markets, firm size and the book-to-market ratio are systematically related to stock returns. Given market imperfections, stocks are priced rather rationally in China, despite the widespread perception to the contrary.     

The dynamics of price discovery for cross-listed shares: Evidence from Australia and New Zealand

This paper studies the dynamics of price discovery for markets with bilateral cross-listings. Using a sample of four Australian stocks cross-listed in New Zealand and five New Zealand stocks cross-listed in Australia for the period January 2002 to December 2007, we assess Hasbrouck (1995) information shares and Grammig et al. (2005) conditional information shares over time. We observe that in both cases the home market is dominant in terms of price discovery. However, when studying price discovery over time, we find that the importance of the Australian market (the larger of the two markets) is increasing for both Australian and New Zealand domiciled firms. Finally, using panel regression analysis, we find that the growth in the importance of the Australian market is positively related to the growth in the size of the firm and negatively related to the size of the percentage spread in the Australian market, implying that as firms grow larger and their cost of trading in Australia declines, the Australian market becomes more informative.     

Barriers to international investing and market segmentation: Evidence from Indian GDR market

In this paper we evaluate market segmentation and its effect on the pricing of cross-listed securities using Indian Global Depositary Receipts (GDRs). When international capital markets are segmented, cross-listed securities may trade at different prices. We test this market segmentation hypothesis using a theoretical and empirical model developed along the lines of Hietala [Hietala, P.T., 1989, Asset pricing in partially segmented markets: Evidence from the Finnish market, Journal of Finance 44, 697–718]) and Foerster and Karolyi [Foerster, S.R., Karolyi, A.G., 1999, The effects of market segmentation and investor recognition on asset prices: Evidence from foreign stocks listing in the United States, Journal of Finance 54, 981–1013; Foerster, S.R., Karolyi, A.G., 1999, The long-run performance of global equity offerings, Working Paper, Ohio State University]. Our model looks at a specific type of market segmentation in India, where capital flow barriers are such that domestic investors are allowed to invest only in domestic securities, while the foreign investors can invest in dollar-denominated Indian GDRs as well as other foreign securities. Tests on these GDRs indicate that foreign investors, who hold these depositary receipts, estimate the expected returns at a lower level than the domestic investors do. This leads to the GDRs being priced at a premium over the exchange rate adjusted prices of the underlying Indian securities. GDR index returns are affected by both domestic and international factors, while the underlying Indian securities are affected only by domestic variables.     

Related securities and price discovery: Evidence from NYSE-listed Non-U.S. stocks

In this paper we analyze whether handling related securities improves a market maker's information environment and helps to incorporate new information in stock prices. Our empirical tests are focused on New York Stock Exchange specialists and the U.S. share in price discovery of 64 British and French companies cross-listed on the NYSE. We define related securities as stocks from the same country, the same region, or other foreign stocks. We find strong evidence that a higher prominence of related stocks in the specialist portfolio is associated with a higher U.S. share in price discovery of our sample firms. We interpret our findings as evidence that concentrating market makers in similar stocks reduces information asymmetries and improves the information environment as market makers can extract information relevant to a stock from order flow to related securities. To support our argument, we show that the adverse selection component of the bid–ask spread is negatively related to the prominence of other foreign stocks in the specialist portfolio.     

Price discovery for cross-listed firms with foreign IPOs

We investigate the inter-market return and volatility linkages for an atypical case of firms with foreign IPOs that subsequently cross-listed in their domestic market. In particular, our data set consists of a unique sample of 29 Israeli firms that went public in the US (host market) and then cross-listed in the Israeli market (home market). To estimate the spillover effects, we employ bivariate GARCH models, assuming both constant and dynamic conditional correlation specifications. At the aggregate market level, we find unidirectional mean and volatility spillovers from the US to the Israeli market. For the portfolios of Israeli cross-listed stocks, we report significant spillovers, at both the mean and volatility levels, from the underlying stocks in the Israeli market to their American Depository Receipts (ADRs) but not vice versa. Thus, the home market dominates the host market in the price discovery process in this atypical international cross-listing case, providing new evidence in support of the home bias hypothesis. We also find that external shocks originating from the Middle East peace process have no impact on the conditional correlation between the two markets but external shocks originating from the world and regional markets impact the conditional correlation positively.     

Price discovery in bitcoin futures

This paper studies the contribution of the newly launched future contracts to the bitcoin price discovery process. Using well-established methodologies in the literature of the evaluation of price discovery in financial markets, we find evidence that, although the volume of bitcoins traded in the decentralized spot market overwhelms that of the futures market, the latter plays a more important role in incorporating new information about the value of bitcoin. Our empirical investigation also provides evidence of strong bi-directional dependence in the intraday volatility of the spot and futures markets.     

Characteristics of stocks that frequently hit price limits: Empirical evidence from Taiwan and Thailand

Daily price limits in the securities markets may affect certain securities more often than other securities. To examine this issue empirically, we examine two stock markets that impose daily price limits (Taiwan Stock Exchange and the Stock Exchange of Thailand). Overall, we find that volatile stocks, actively traded stocks, and small market capitalization stocks hit price limits more often than other stocks. Our findings, therefore, provide new considerations into the current discussions surrounding price limit mechanisms, an important topic in which very little is known.     

One Security,Many Markets: Determining the Contributions to Price Discovery

When homogeneous or closely-linked securities trade in multiple markets, it is often of interest to determine where price discovery (the incorporation of new information) occurs. This article suggests an econometric approach based on an implicit unobservable efficient price common to all markets. The information share associated with a particular market is defined as the proportional contribution of that market's innovations to the innovation in the common efficient price. Applied to quotes for the thirty Dow stocks, the technique suggests that the preponderance of the price discovery takes place at the New York Stock Exchange (NYSE) (a median 92.7 percent information share).     

Price discovery in tick time

This paper develops a tick time model for the quote setting dynamics on Nasdaq. The model decomposes quotes into an efficient price, asymmetric information and noise. Both the evolution of the efficient price and the information contents of quotes depend on quote durations. New measures for the contribution to price discovery are defined within this model. When aggregated to fixed calendar time intervals, they relate closely to Hasbrouck [Hasbrouck, Joel, 1995, One security, many markets: determining the contribution to price discovery, Journal of Finance 50, 1175–1199] information shares. Empirical results for 20 Nasdaq stocks indicate that ECNs, in particular Island, contribute most to price discovery for active stocks. For less active stocks, wholesale market makers contribute most.     

Informed Trading in Stock and Option Markets

We investigate the contribution of option markets to price discovery, using a modification of Hasbrouck's (1995) "information share" approach. Based on five years of stock and options data for 60 firms, we estimate the option market's contribution to price discovery to be about 17% on average. Option market price discovery is related to trading volume and spreads in both markets, and stock volatility. Price discovery across option strike prices is related to leverage, trading volume, and spreads. Our results are consistent with theoretical arguments that informed investors trade in both stock and option markets, suggesting an important informational role for options.     

Price discovery in spot and futures markets: a reconsideration

We reconsider the issue of price discovery in spot and futures markets. We use a threshold error correction model to allow for arbitrage opportunities to have an impact on the return dynamics. We estimate the model using quote midpoints, and we modify the model to account for time-varying transaction costs. We find that (a) the futures market leads in the process of price discovery and (b) the presence of arbitrage opportunities has a strong impact on the dynamics of the price discovery process.
