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.     

Capital Flow Controls,International Asset Pricing,and Investors' Welfare: A Multi-Country Framework

This paper investigates the impact of capital flow restrictions on the pricing of securities, on the optimal portfolio composition for investors of different nationalities, and on their welfare. Under capital flow controls, the equilibrium price of a security is determined jointly by its international and national risk premiums, and investors acquire nationality-specific portfolios along with a market-wide proxy for the world market portfolio. Removal of investment barriers generally leads to an increase in the aggregate market value of the affected securities, and all investors favor a move toward market integration. Introduction of different types of index funds in the world market generally increases world market integration and investor welfare.     

Are there too many safe securities? Securitization and the incentives for information production

We present a model that helps explain several past collapses of securitization markets. Originators issue too many informationally insensitive securities in good times, blunting investor incentives to become informed. The resulting endogenous scarcity of informed investors exacerbates primary market collapses in bad times. Inefficiency arises because informed investors are a public good from the perspective of originators. All originators benefit from the presence of additional informed investors in bad times, but each originator minimizes his reliance on costly informed capital in good times by issuing safe securities. Our model suggests regulations that limit the issuance of safe securities in good times.     

投资者异质性与证券市场定价——理论模型与中国的经验证据

本文从投资者异质性的客观现实出发,通过对投资者二维视角的交叉分类与相关行为的探讨,提出了一种按交易特点与行为依据的新的分类方案,即将投资者分为套利交易者、价格预期交易者和量能变动交易者三类。在此基础上分别建立了各类投资者的需求函数,通过对证券市场供求函数的讨论,利用均衡分析方法构建了基于投资者异质性的证券市场定价模型,并以我国证券市场1999-2011年的月度数据为样本进行了实证分析。实证结果表明:我国证券市场价格主要由价格预期交易者的诱导性策略行为与量能变动交易者的羊群行为决定,套利交易者的套利行为对市场价格没有显著的影响,证券市场扩容也未对市场价格的形成产生系统性冲击。     

DIVERGENT EXPECTATIONS AND THE ASIAN FINANCIAL CRISIS OF 1997

An important question concerning integration of global financial markets is whether local investors in an equity market react differently from international investors, particularly during periods of financial crisis. Considering local investors are closer to information, they might turn pessimistic before foreign investors before a crisis. We examine whether local investors in each of the six Asian stock markets—Indonesia, Korea, Malaysia, the Philippines, Taiwan, and Thailand—reacted differently from international investors during the 1997 Asian financial crisis. Our empirical results indicate that, in general, closed‐end country fund share prices (mainly driven by foreign investors) Granger‐cause the respective net asset values (NAVs, mainly driven by local investors). Moreover, this one‐way Granger‐causality effect from share prices to NAVs becomes much stronger during the crisis period after controlling for U.S. stock returns. Our results suggest international investors turned pessimistic before local investors. JEL classification: G15     

m-Double Poisson Lévy markets

We develop novel mispricing of markets under asymmetric information and jumps for informed and uninformed investors, called m-Double Poisson markets, driven by independent Double Poisson processes. In the special case m?=?1, called the Double Poisson pure-jump Lévy market, both types of investors hold the same optimal portfolio and expected utility, and hence, the informed investor has no utility advantage over the uninformed. For the general market, instantaneous centralized moments of returns are used to compute optimal portfolios and utilities. The mean, variance, skewness and kurtosis of instantaneous returns are reported using jump amplitudes and frequencies.     

Correlation and Volatility Dynamics in International Real Estate Securities Markets

We study international correlation and volatility dynamics of publicly traded real estate securities using monthly returns from 1984 and 2006. We also examine, for comparison, the correlations among the corresponding stock markets. A multivariate dynamic conditional correlation model captures the time-varying correlation within the full period. We confirm lower correlations between all real estate securities market returns than those between the stock market returns themselves. Some significant variations and structural changes in the correlation structure happened within the sample period. We detect a strong and positive connection between real estate securities market correlations and their conditional volatilities. We also find the international correlation structure of real estate securities and the broader stock market are linked to each other. Our results have economic motivations regarding the potential integration of international real estate securities markets and the possibility of including information on changing correlations and volatilities to design more optimal portfolios for international real estate securities.

Reversal of Monday returns

This paper elaborates an interesting aspect of the Monday anomaly: Monday returns are relatively more likely to reverse over the subsequent days. We document that, although the Monday low-return anomaly disappeared, the subsequent reversal of Monday returns remains robust to date. The reversals, measured over a five-day horizon, are pervasive across international stock markets, reasonably stable over time, significant following both positive and negative Monday returns, and not confined to extreme Monday returns. Trading strategies designed to exploit these reversals earn economic profits. We examine potential explanations for the reversal of Monday returns using trading flows data of investor types from Korea. All predictions of the Foster and Viswanathan [J. Finance, 1993, 48, 187–211] model are confirmed: volatility is higher, trading volume is lower, market depth is lower and price impact costs are higher on Mondays. The model implies lower price quality on Mondays, but does not specifically predict reversal of Monday returns. We show that the trading intensity of international/institutional investors is lower on Mondays. This appears to make the market relatively more susceptible to individual investors’ trading, which is negatively correlated with international/institutional investors. Thus, Monday returns are relatively more likely to reverse during the subsequent days of the week when institutional investors trade more aggressively.     

Contrasting Worldviews at Bank and Securities Market Regulators

Bank and securities regulators operate with different attitudes about the appropriate regulation of financial institutions and markets. Bank regulators’ prudential oversight protects depositors from worrying about the repayment of their bank claims. In contrast, securities market regulators tend to presume that security markets (almost) always clear quickly at prices close to the asset's fundamental value. These regulators seek to assure full disclosure of information, which facilitates active securities trading. In the United States, the Securities and Exchange Commission's (SEC) investor protection duties are tailored to the financial sophistication of individual investors.     

US and Domestic Market Gains and Asian Investors’ Overconfident Trading Behavior

We find that subsequent to both US and domestic market gains, both Asian individual and institutional investors increase their trading and that this effect is more pronounced in bull markets, in periods of relatively favorable investor sentiment, in periods of extremely high market returns, and in markets with short‐sale constraints. We also find that individual investors trade more in response to market gains than institutional investors. Moreover, we find that further integration of Asian stock markets with US stock markets after the Asian financial crisis in 1998 is an important reason for Asian investors’ response to US market gains.     

Are the gains from international portfolio diversification exaggerated? The influence of downside risk in bear markets

The fundamental rationale for international portfolio diversification is that it expands the opportunities for gains from portfolio diversification beyond those that are available through domestic securities. However, if international stock market correlations are higher than normal in bear markets, then international diversification will fail to yield the promised gains just when they are needed most. We evaluate the extent to which observed correlations to monthly returns in bear, calm and bull markets are captured by three popular bivariate distributions: (1) the normal, (2) the restricted GARCH(1,1) of J. P. Morgan’s RiskMetrics, and (3) the Student-t with four degrees of freedom. Observed correlations during calm and bull markets are unexceptional compared to these models. In contrast, observed correlations during bear markets are significantly higher than predicted. Higher-than-normal correlations during extreme market downturns result in monthly returns to equal-weighted portfolios of domestic and international stocks that are, on average, more than two percent lower than those predicted by the normal distribution. If the extent of non-normality during bear markets persists over time, then a US investor allocating assets into foreign markets might want to allocate more assets into foreign markets with near-normal correlation profiles and avoid markets with higher-than-normal bear market co-movements.

Taxes and portfolio composition

This paper explores investors portfolio behavior when security returns can be described by one of the forms of the CAPM model and investors pay taxes. The conditions under which an investor holds the market portfolio are explored. In addition the extent to which securities are held in proportions which differ from market weights are shown to be functions of tax rates, dividend policies, and the variance covariance structure between all securities.     

Does a Held-to-Maturity Strategy Impede Effective Portfolio Diversification for Islamic Bond (Sukuk) Portfolios? A Multi-Scale Continuous Wavelet Correlation Analysis

There is a critical gap in the literature in studying the portfolio diversification opportunities available to sukuk investors and evaluating these in light of held-to-maturity strategies usually adopted by these investors. This article has made an initial attempt to study the portfolio diversification strategies for sukuk portfolios across heterogeneous investment horizons. Our findings critically indicate that returns between local currency sukuk in different markets generally have low levels of correlations across different investor holding periods, thus enabling both short and long-run portfolio diversification benefits. However, in contrast, international currency sukuk issued in different markets exhibits high levels of correlations in the longer-term investor holding periods. Also, in the domestic market context, returns on different classes of domestic sukuk are found to exhibit strong correlations in the longer-holding periods. Our findings critically highlight the feasibility of held-to-maturity sukuk investment strategies from a portfolio diversification perspective.     

The networking function of investment banks: Evidence from private investments in public equity

We examine investment banks' networking function in capital markets, using a sample of Private Investments in Public Equity (PIPEs). We argue that investment banks develop relationships with investors through repeat dealings, and that investment banks' networks of relationship investors form the basis of their networking function. We find that investment banks, especially those with larger investor networks, help issuers attract investors. Correspondingly, an issuer that desires more investors is more likely to hire an investment bank than place the shares directly. We also find that issuers pay higher fees to hire investment banks with larger investor networks. Our empirical findings suggest that the networking function of investment banks is important in securities offerings.     

Leverage Constraints and the International Transmission of Shocks

Recent macroeconomic experience has drawn attention to the importance of interdependence among countries through financial markets and institutions, independently of traditional trade linkages. This paper develops a model of the international transmission of shocks due to interdependent portfolio holdings among leverage‐constrained investors. In our model, without leverage constraints on investment, financial integration itself has no implication for international macro comovements. When leverage constraints bind, however, the presence of these constraints in combination with diversified portfolios introduces a powerful financial transmission channel that results in a positive comovement of production, independently of the size of international trade linkages. In addition, the paper shows that with binding leverage constraints, the type of financial integration is critical for international comovement. If international financial markets allow for trade only in noncontingent bonds, but not equities, then the international comovement of shocks is negative. Thus, with leverage constraints, moving from bond trade to equity trade reverses the sign of the international transmission of shocks.     

THE LIQUIDITY ROUTE TO A LOWER COST OF CAPITAL

The managements of many public companies do not pay much attention to the liquidity of their securities. Many if not most CEOs and CFOs feel powerless to affect what goes on in financial markets, and a common attitude among top executives is that maintaining liquidity is the concern of the securities exchanges and the Securities and Exchange Commission. This approach may work for those companies whose stocks are already highly liquid—a group made up mainly of large‐cap companies, as well as a number of smaller high‐flying, high‐tech firms. But, for the vast majority of public companies—especially smaller and mid‐sized firms—this is likely to be the wrong policy. As the authors of this article demonstrated in their pioneering study (published in the Journal of Financial Economics in 1986), liquidity appears to be a major determinant of a company's cost of capital. As their theory suggests and their empirical tests confirmed, the more liquid a company's securities, the lower its cost of capital and the higher its stock price. And, as discussed in this article, academic research since then has produced a large and impressive body of evidence linking greater liquidity to higher stock prices. Although recent technological innovations such as Internet‐based trading have increased liquidity generally, not all companies appear to have benefited equally. The authors offer a number of suggestions for companies intent on increasing the liquidity of their stock. Specifically, they propose that managers do the following: (1) consider measures, such as stock splits, designed to increase their investor base by attracting small investors; (2) seek trading venues for their securities that promise to increase liquidity; and (3) take advantage of the new Internet technology to provide more and better information to investors. Moreover, for smaller companies with little or no analyst coverage, the authors offer the radical suggestion that such companies actually pay analysts to cover their stock, much as companies pay Moody's or Standard & Poors to rate their bonds. This, in the authors' view, would be a more efficient alternative to the current practice of using stock splits to encourage intermediaries to make markets in the firm's shares.     

The appraisal of ordinary shares by Saudi investors

This paper reports on a questionnaire survey about share valuation practices among investors and their intermediaries in Saudi Arabia. The findings suggest that fundamental analysis is used most by investor respondents where a P/E multiple is applied to an earnings forecast to generate a prediction of future price. However, technical analysis is also used to a much greater extent than in developed markets. Finally, the results indicate that quarterly and annual reports as well as newspapers are widely consulted by investors when forming their expectations about share valuations.     

Overconfidence and Investor Size

Recent research documents that institutional or large investors act as antagonists to other investors by showing opposite trading behaviour following the disclosure of new information. Using an extremely comprehensive official transactions data set from Finland, we set out to explore the interrelation between investor size and behaviour. More specifically, we test whether investor size is positively (negatively) correlated with investor reaction following positive (negative) news. We document robust evidence of that investor size affects investor behaviour under new information, as larger investors on average react more positively (negatively) to good (bad) news than smaller investors. We furthermore find that the performance of smaller, or more overconfident, investors is in general hurt by their behaviour.     

我国证券投资者权益保护问题研究
