Multi-market trading and arbitrage

We measure arbitrage opportunities by comparing the intraday prices and quotes of American Depositary Receipts (ADRs) and other types of cross-listed shares in U.S. markets with synchronous prices of their home-market shares on a currency-adjusted basis for a sample of 506 U.S. cross-listed stocks from 35 different countries. Deviations from price parity average an economically small 4.9 basis points, but they are volatile and can reach large extremes. Price parity deviations and their daily changes are positively related to proxies for holding costs that can impede arbitrage, even after controlling for transactions costs and foreign investment restrictions.

Homemade international diversification under economic policy uncertainty

We examine how US mutual funds that invest domestically make portfolio adjustments by incorporating US-listed foreign stocks (cross-listed stocks) when faced with US market economic policy uncertainty. We document a positive association between US economic policy uncertainty and US mutual funds’ weight of cross-listed stocks, and find that the effect is concentrated in funds that mainly invest in the US domestic market. The findings are not sensitive to the instrumental variable approach, model specification, sampling, variable definition, and controlling for macro characteristics. Funds with higher weight of cross-listed foreign stocks when US economic policy uncertainty increases outperform other funds, indicating the rationality of such an investment strategy. A long-short portfolio generates 3.4% annualized abnormal return in the immediate following quarter. Our study shields light not only on the international diversification benefit of US-listed foreign stocks but also on the importance of capital market openness for domestic investors.     

Trades in commodities,financial assets,and currencies: A triangle of arbitrage,hedging and speculative designs

This work brings three markets — (i) commodities (e.g., steel iron ores, electronic parts, oil), (ii) financial assets (such as various stocks, bonds, notes), and (iii) different currencies (like U.S. dollar, British pound, euro, yen and so on) and examines the scope of triple operations of arbitrage, hedging, and speculation. Trading of cross-listed cross-currency assets with arbitrage and hedging is already recorded and analyzed. Here one more dimension — cross-country trades in commodities are added, and speculation is juxtaposed too within one framework.     

Determining the contributions to price discovery for Chinese cross-listed stocks

We study the price-discovery process for a number of Chinese cross-listed stocks. For the stocks cross-listed on the New York Stock Exchange (NYSE) and the Stock Exchange of Hong Kong (SEHK), we find that the stock prices of these two exchanges are cointegrated and mutually adjusting, and that the SEHK makes more contributions than the NYSE to the price-discovery process. The SEHK contributions are 81.6% and 89.4%, computed from Gonzalo and Granger [Gonzalo, J., Granger, C., 1995. Estimation of common long-memory components in cointegrated systems. Journal of Business and Economics Statistics 13, 27–35] permanent–transitory (PT) and Hasbrouck [Hasbrouck, J., 1995. One security, many markets: Determining the contributions to price discovery. Journal of Finance 50, 1175–1119] information share (IS) models respectively.     

Fundamental strength strategy: The role of investor sentiment versus limits to arbitrage

This paper evaluates the return predictability of fundamental strength in a two-dimensional framework that considers both investor sentiment and limits to arbitrage simultaneously. Sentiment and limits to arbitrage have independent and overlapping explanatory power on the return predictability of fundamental strength. The return predictability of fundamental strength is more pronounced among stocks with high arbitrage costs following high sentiment. Among stocks with low arbitrage costs, the fundamental strength strategy is profitable only following high sentiment. However, among stocks with high arbitrage costs, the same strategy can earn economically and statistically significant profits even following low sentiment. Consistent with Miller (1977), we emphasize the interaction of sentiment and limits to arbitrage on stock valuation.     

Social media and price discovery: The case of cross-listed firms

In this article, we examine whether social media information affects the price-discovery process for cross-listed companies. Using over 29 million overnight tweets mentioning cross-listed companies, we examine the role of social media for a link between the last periods of trading in the US markets and the first periods in the UK market. Our estimates suggest that the size and content of information flows on social networks support the price-discovery process. The interactions between lagged US stock features and overnight tweets significantly affect stock returns and volatility of cross-listed stocks when the UK market opens. These effects weaken and disappear 1 to 3 hr after the opening of the UK market. We also develop a profitable trading strategy based on overnight social media, and the profits remain economically significant after considering transaction costs.     

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.     

Cross-Listing, Bonding Hypothesis and Corporate Governance

Abstract:  This paper examines the relationship between cross-listing and corporate governance for Canadian firms, that were cross-listed on US stock exchanges during the period 1997–2003. We find that cross-listed firms have more independent boards and audit committees after the listing relative to a non-cross-listed matched sample of firms and relative to the pre-listing period. Moreover, cross-listed firms experience changes in their ownership structure after the listing. Finally, we provide evidence that the sensitivity of the relation between cross-listed firm valuation with audit committee independence and ownership structure becomes more important after the listing. The results are robust after adjusting for various firm risk characteristics. Overall, the results are consistent with the literature on the bonding role of cross-listings on US stock exchanges.     

LIQUIDITY AND TICK SIZE: DOES DECIMALIZATION MATTER?

The effect of the move to decimalization by the Toronto Stock Exchange, where the minimum tick size was decreased to $0.05 from $0.125, is examined. Liquidity is measured by the price impact of unexpected volume. Results show an unambiguous gain to investors. Effective spreads decrease significantly, but the price impact is unaffected. In addition, evidence indicates an increase in trading activity in absolute terms as well in relation to U.S. exchanges for cross-listed stocks. This is consistent with the observed decrease in transaction costs.     

Costly arbitrage and idiosyncratic risk: Evidence from short sellers

Previous studies have shown that high short interest stocks have low subsequent returns. We test whether the persistence of this effect is due to costs limiting arbitrage. The arbitrage cost that we focus on is idiosyncratic risk which, regardless of the arbitrageur’s level of diversification, deters arbitrage activity. Consistent with costly arbitrage, we find that among high short interest stocks a one standard deviation increase in idiosyncratic risk predicts a more than 1% decline in monthly returns. Moreover, idiosyncratic risk does not predict returns across low short interest stocks, and short interest does not predict low returns across low idiosyncratic risk stocks. Our results are robust to commonly used proxies for both transaction costs and short sale constraints.     

U.K. and U.S. trading of British cross-listed stocks: an intraday analysis of market integration

This article analyzes intraday patterns for U.K. and U.S. tradingof British cross-listed stocks. For each market, the intradaypatterns for these stocks closely resemble those of otherwisesimilar, non-cross listed stocks. There is a 2-hour period eachday when cross-listed stocks are traded both in New York andin London. This overlap is characterized by concentrated tradingas private information, originating in New York, gets incorporatedinto prices in both markets. Cross-border competition for orderflowtends to reduce already declining spreads in London. By contrast,New York specialists maintain     

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.     

Cross-Listing and Operating Performance: Evidence from Exchange-Listed American Depositary Receipts

Abstract:  In this paper we examine the operating performance of non-US firms that enter major US stock exchanges using American Depositary Receipt (ADR) programs. Our dataset consists of 108 capital-raising and non-capital-raising firms from twenty four countries, cross-listed on major US stock exchanges during the period 1994–2004. We provide evidence that capital-raising cross-listed firms experience improvements in their operating performance after the listing, relative to a non-cross-listed matched sample of firms and relative to the pre-listing period, whereas non-capital-raising cross-listed firms out-perform a non-cross-listed matched sample of firms for both the pre-listing and the post-listing periods. These results suggest that the type of ADR program conveys information about changes in the post-listing operating performance. Moreover, both capital-raising and non-capital-raising cross-listed firms have positive abnormal returns due to the cross-listing and these abnormal returns are positively related with the post-listing abnormal changes in operating performance, suggesting that the market anticipates the post-listing abnormal changes in operating performance. Results are robust after adjusting for various firm and country risk characteristics.     

Voluntary disclosure practices by foreign firms cross-listed in the United States

This is one of the first large-scale studies to examine the voluntary disclosure practices of foreign firms cross-listed in the United States. We proxy for voluntary disclosure using three attributes of firms’ management earnings guidance: (1) the likelihood of issuance; (2) the frequency of earnings guidance; and (3) a guidance quality measure. After first establishing that market participants view these firms’ disclosures as credible and economically important (i.e., the disclosures are negatively related to analyst forecast errors and the implied cost of equity capital), we compare cross-listed firms’ disclosure practices with comparable US firms and explore variations in disclosure practices among cross-listed firms. We find that cross-listed firms issue less frequent and lower quality management earnings guidance than comparable US firms. We further show that the gap between US and cross-listed firms widened after passage of Regulation FD, a regulation which induced greater public disclosure of firm-specific information. Focusing on the sample of cross-listing firms, we show that firms from common-law countries disclose more than firms from code-law countries. Finally, our results indicate that cross-listed firms that do not list on an organized US exchange provide more frequent and higher quality disclosure than those that do list on organized exchanges.     

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.     

Multiple duration analyses of dynamic limit order placement strategies and aggressiveness in a low-latency market environment

This study examines dynamic order placement strategies in a low-latency environment together with limit orders' aggressiveness by a new approach which utilises survival analysis with a multiple-spell duration model. Two samples are considered, including the period immediately followed Australian Securities Exchange (ASX)’s migration to Integrated Trading System (ITS) and the period subsequent to the launch of ASX Trade. We find the evidence supporting both the ‘cost of immediacy hypothesis' and the ‘chasing hypothesis' as in Hasbrouck and Saar (2009). Furthermore, several distinctions in the results are found between the samples of ITS period and ASX Trade period as well as between the samples of small-cap stocks and large-cap stocks. The findings of this study are beneficial not only for high-frequency traders in forming dynamic order placement strategies in a low-latency stock market environment, but also for market regulators in helping their attempt to improve regulations for stock exchanges.     

Options Arbitrage in Imperfect Markets

Option valuation models are based on an arbitrage strategy—hedging the option against the underlying asset and rebalancing continuously until expiration—that is only possible in a frictionless market. This paper simulates the impact of market imperfections and other problems with the “standard” arbitrage trade, including uncertain volatility, transactions costs, indivisibilities, and rebalancing only at discrete intervals. We find that, in an actual market such as that for stock index options, the standard arbitrage is exposed to such large risk and transactions costs that it can only establish very wide bounds on equilibrium options prices. This has important implications for price determination in options markets, as well as for testing of valuation models.     

STOCK MARKET OPENNESS AND MARKET QUALITY: EVIDENCE FROM THE SHANGHAI–HONG KONG STOCK CONNECT PROGRAM

We study the impact of capital market openness on high-frequency market quality in China. The Shanghai–Hong Kong Stock Connect program (SHHKConnect) opens China's stock market to foreign investors and offers a natural experiment to investigate this question. Using a difference-in-differences approach, we find that market liberalization leads to lower quoted spread, lower effective spread, lower market depth, and higher short-term volatility. Our findings imply that opening the markets to more sophisticated foreign investors is associated with higher competition and more cross-market arbitrage activities, narrowing the spread and reducing liquidity providers’ profits, but increasing the price impact and short-term volatility of connected stocks.     

Does bonding really bond? Liability of foreignness and cross-listing of Chinese firms on international stock exchanges

This study examines the relationship between cross-listing and firm valuation in the context of Chinese firms cross-listed on major international exchanges, such as the NASDAQ, New York Stock Exchange (NYSE), Hong Kong Main Board, Hong Kong Growth Enterprise Market (GEM), Singapore Stock Exchange, and London Alternative Investment Market (LAIM). Through the lenses of bonding theory and liability of foreignness-based multinational enterprise theories, two sets of alternative hypotheses are developed and tested using panel data over a period of twelve years during 2001–2012. Contrary to the bonding theory, the results reveal that the firms listed in Mainland China recorded better valuation than the firms cross-listed on the international stock exchanges. The more sophisticated corporate governance mechanisms applied in international stock exchanges do not always entail better firm valuation. Institutional distance, cultural distance and the distance in economic freedom between China and the cross-listing location countries interact with governance variables negatively affecting performance of cross-listed firms. The direct negative impact of the three distance variables on the firm valuation is also statistically significant. The outcome of Chinese firms’ cross-listing behaviours appears to contradict the general bonding theory.
