Though stock portfolio return autocorrelation is well documented in the literature, its cause is still not clearly understood. Presently, evidence of private information induced stock return autocorrelation is still very limited. The difficulty in obtaining foreign country information by small investors makes the private information of institutional investors in the ADR (American Depository Receipt) market more significant and influential. As such, the ADR market provides a favorable environment for testing the effect of private information on return autocorrelation. The purpose of this paper is to address this issue.

In this paper, ADRs are sorted annually into three groups based on market equity capitalization. Within each capitalization group, ADRs are further sorted into three groups based on the fraction of shares held by institutional investors. Each ADR is assigned to one of the nine groups and group membership is rebalanced each year. The return autocorrelation of individual ADR securities and ADR portfolios for each group are then calculated.

The results demonstrate that ADR individual stock and portfolio daily return autocorrelations are positively related to institutional ownership. It is also found that other explanations, such as non‐synchronous trading, bid‐ask spread and volatility of ADR, cannot explain the positive relation between daily return autocorrelations and institutional ownership of ADR.

Since ADR market is more suitable than other markets for testing the role of private information, stronger and clearer results are got accordingly. This paper suggests that trading strategy based on private information of institutional investors can lead to stock return autocorrelation in ADR daily returns.

This study examines the initial two‐week excess performance relative to the S&P 500 Index of American Depository Receipts (ADRs) listed on the New York Stock Exchange from January 1987 to September 2001 to determine whether short‐term wealth effects exist.

Standard intial public offering methodology is used to test for significant excess performance.

Results for the entire sample of 281 ADRs suggest the initial excess performance was not significant. However, after segmenting the sample, emerging market ADRs significantly outperformed the S&P 500 by over three per cent while developed market ADRs underperformed by 0.92 per cent. Also, Latin American ADRs outperformed the market index by nearly five per cent during the first two weeks after issue while European ADRs underperformed the market by nearly one per cent. Asia Pacific ADRs underperformed the S&P 500, but not significantly in the early trading.

The findings suggest emerging market ADRs, particularly those from the Latin American region, perform well in the early trading while developed market ADRs do not. Future research may identify variables that affect or explain ADR excess returns.

The paper provides insights into the types of ADRs that accumulate wealth in the short term investment horizon.

The purpose of this paper is to determine what types of short-term wealth effects accrued to European and Latin American American Depository Receipt (ADR) investors and whether these were affected by the type of issue (initial public offerings (IPO) vs seasoned equity offerings (SEO)) or the date of issue (1990s vs 2000s).

Standard ADR and IPO excess return methodology is utilized to compute and test excess returns against a US investment benchmark. This methodology is used in many ADR and IPO studies.

European SEOs listed in the 2000s did better than those listed in the 1990s. The results for European IPOs were the opposite. Latin American SEOs did better relative to the US market index for issues listed in the 1990s as compared to those listed in the 2000s. Once again the results for Latin American IPOs were the opposite.

This study differs from previous studies by emphasizing differences in short-term return behaviour for Latin American and European ADRs listed during a decade of US market stability (the 1990s) vs those listed in the 2000s when the US stock market encountered times of extreme return volatility. These timing differences affect not only the returns of all the ADRs but also show how ADR IPOs and SEOs tend to have opposite return behaviour based on timing. These return differences are important because the major benefits of portfolio diversification are achieved when asset returns are less correlated with each other.

Adverse drug reactions (ADRs) are increasingly recognised as an important cause of morbidity and mortality. Psychiatric patients, and especially those in forensic units, may be at increased risk of ADRs. Detection and documentation of previous ADRs are essential in reducing the risk of future ADRs. A baseline audit was undertaken, and subsequently the recording of ADRs on the drug cards of patients in a forensic psychiatry unit was re‐audited. Poor levels of documentation of ADRs were found. Following the baseline audit, a number of simple measures were undertaken which improved performance at re‐audit.

The purpose of this study is to determine whether Latin American ADRs provided US investors with international diversification benefits as determined by comparing excess returns from issues listed in the 1990s to those listed in the 2000s. A further sample breakdown compares IPO returns to SEO returns.

Standard ADR return methodology used in many previous studies is utilized to compute and test excess returns. This methodology is the same as the standard methodology used in IPO studies.

The total Latin American ADR sample returned roughly the same as the S & P 500 index for the three year holding period; however, those issued before 2000 underperformed the index by nearly 19 percent while those listed after January 1, 2000 outperformed the index by nearly 58 percent. The excess returns of IPOs were nearly 50 percent less than SEOs when compared to the index. Also, both IPOs and SEOs listed after the new millennium began drastically outperformed those listed in the 1990s (when compared to the S & P 500 index).

This study differs from previous studies by emphasizing differences in return behaviour for Latin American ADRs listed during a decade of steady sustained growth (the 1990s) versus those listed in the 2000s when the US stock market encountered times of extreme return volatility. The implications of the return differences help determine whether these ADRs provided investors with true diversification benefits. Also, the dataset includes fresh results for ADRs listed during and trading through the mortgage crisis of 2008.

The authors investigate how market quality diverges between foreign firms and domestic firms on the US stock market in response to the Russia–Ukraine conflict.

With an event study approach, the authors compare foreign firms with domestic firms in their market responses over the three-day window around the outbreak of the war. Further, with Difference-in-Difference (DID) analyses, the authors study the change in foreign firms' market quality upon this outbreak in comparison with their domestic counterparts. Finally, the authors compare the foreign firms across firm specific characteristics and home country characteristics.

The authors find that foreign stocks listed in the US experience more severe market quality deterioration compared to the stocks' domestic counterparts. This effect is especially strong for companies from countries considered friendlier towards Russia and companies that are not cross-listed. The authors' findings are consistent with the information asymmetry hypothesis concerning market quality. Moreover, US market investors have more concerns over political risks with non-US-aligned political standings during war times.

The authors' findings are consistent with the information asymmetry hypothesis concerning market quality. Moreover, US market investors have more concerns over political risks over non-US-aligned political standings during war time.

Since both countries in the conflict are in Europe, the US stock market, to a certain degree, becomes a safe haven for capital from Europe and other countries. In the meantime, American Depository Receipts (ADRs) have been important for US investors to create a globally diversified portfolio, and the knowledge regarding ADRs' vulnerability to international geopolitical events is valuable. The author' results are informative for stock market investors to understand the market dynamics for international and domestic companies during this extremely uncertain time.

This is the first study that examines the market quality divergence between foreign firms and domestic firms on the US stock market in response to the Russia–Ukraine conflict. The authors provide novel evidence on the change in ADRs' market quality associated with significant political uncertainty. The authors show that ADRs' market quality is more vulnerable to international geopolitical risks relative to otherwise comparable domestic firms.

This study tests the signaling and tunneling models of dividend policies by examining the relationship between the ownership structure and the dividend payout in a setting where strong institutional governance and weak firm-level governance coexist.

Chinese American Depository Receipts (ADRs) listed in the US offer an excellent opportunity to study dividend policy where strong institutional governance and weak firm-level governance coexist. Using a sample of 161 Chinese ADRs from 2004 to 2018, this study examines the relationship between the firm's ownership structure and cash dividend policy.

This study shows that high levels of controlling shareholder ownership and high levels of state ownership are associated with high dividend payouts. A high level of controlling shareholder ownership has a negative effect on its firm value. Dividend payments in those firms mitigate the negative effect, consistent with the signaling (substitution) model. A high level of state ownership is beneficial to its firm value. However, high dividend payment in those firms decreases the benefit, supporting the tunneling model.

This study covers 161 Chinese ADRs listed in the US with a total market capitalization of over $2 trillion and reveals that dividend tunneling could occur in Chinese government controlled ADRs. Findings in this study would offer valuable insights for US investors and regulators.

This paper extends the tunneling hypothesis to the topic of dividend policy in a setting where strong institutional governance and weak firm-level governance coexist. This study shows that tunneling through dividends can happen among Chinese government controlled ADRs in the US. It also complements the literature by extending the examination of the dividend tunneling model from a relatively small universe of master limited partnership (Atanssov and Mandell, 2018) to a larger universe of Chinese ADRs listed in the US with a total market capitalization over $2 trillion US dollars.

In this paper, the authors aim to test the assertion that options act as a substitute for short sales by allowing investors an alternative way to act on bearish sentiment. An empirical test of this assertion requires a researcher to observe both types of firm – those that weren’t short sale constrained, as well as those that were. The authors examine the ability of options to alleviate the short sales constraint directly – in an environment where the constraint is likely to differ across firms in a systematic fashion, namely the market for American Depository Receipts (ADRs).

The authors examine 190 option introductions on ADRs over the period of 1982 to 2006. The question of how ADRs are chosen for options listing, and whether those criteria differ from those found using purely domestic options, is addressed using logistic regressions. The authors use the event study methods of Brown and Warner to examine the price effect of the listing. They use OLS regression to identify determinants of the cumulative abnormal return upon option listing. Independent variables are those indicated by existing literature that examines option listing on domestic securities.

In an environment where the effective short sale constraint varies across firms, the authors find support for the contention that US option listings reduce the effect of the short sales constraint, providing relief for investors who have negative sentiment about the stock and are subject to a short sale constraint. However, it does not appear that option listing entities seek out companies for which short sale constraints are stronger.

The authors’ hypotheses are similar to those of Mayhew and Mihov and of Danielson and Sorescu, but the authors assert that the ADR market is a more robust environment in which to test the hypotheses. This is due to the potentially large variation in the effective short sale constraints that results from the differences in their underlying home market legal and regulatory environments. In addition to relative short interest and the change in relative short interest, this environment allows the authors to use indicator variables to directly test the ability of options to substitute for short sales.

The purpose of this paper is to investigate the effect of cross-listing on the size and structure of director compensation at individual director level. While much of the prior literature has focused on executive compensation, more recent literature has started to examine director compensation. Additionally, there has been extensive literature examining the impact of cross-listing on the corporate governance and equity valuation of listed firms. The literature, however, has largely ignored the effect of cross-listing on director compensation schemes. This study attempts to combine these two literature streams and examine the effect of cross-listing on director compensation.

This study uses American Depository Receipts (ADRs) and matched non-ADRs from the same country and industry to test the relationship between cross-listing and director compensation. Regressions with country, year and industry fixed-effects are employed. The relationship is further examined using only ADR firms during pre-listing and post-listing periods.

This study finds that directors of ADR firms receive higher total compensation and greater percentage equity-based compensation relative to directors of non-ADR firms. This study also finds that such differences in director compensation are dependent on the cross-listing program a firm is registered to. Directors of ADR firms also receive higher total compensation and greater percentage equity-based compensation during post-listing periods relative to their own compensation during pre-listing periods.

This study extends the literature on director compensation in a global setting, and is the first to examine an unanswered question regarding the effect of cross-listing on director compensation. This study provides important information that cross-listing affects the size and structure of director compensation between ADR and non-ADR firms, as well as between pre-listing and post-listing periods for ADR firms themselves.

Cross-listed firms may face unique incentives for establishing dividend policies in comparison to US firms. This study aims to test the implications of the lifecycle and signaling theories of dividend policy in the context of non-US firms cross-listed on US stock exchanges via American depository receipts (ADRs).

ADRs are classified according to the firms' dividend paying histories as regular payers, non-payers, former payers, new payers and switchers. Multinomial logit regressions measure the likelihood of dividend payers to pay dividends, as well as the possibility of a dividend amount increase, decrease, or no change, based upon previously identified determinants of dividend payments and a measure of economic conditions in the home country.

The results indicate that firm size, growth opportunities, and the mix of earned and contributed capital partially explain observed dividend policies for ADR firms. Multinomial logit regressions reveal profitability and home-country macro-economic conditions significantly affect ADR firms' decisions to change their dividend policies.

The findings suggest macro-economic conditions affect dividend payment changes among ADR firms. The results also imply that the lifecycle and catering theories may help explain dividend changes among ADR firms.
