What do bond holdings reveal about international funds' preferences?

International bond funds are important institutional investors in emerging markets and their asset allocation decisions have significant implications for bond market developments and debt management policies in developing countries. This paper studies emerging market bond holdings of international funds and analyzes economic and financial factors affecting their bond preferences. It shows that mutual funds prefer to invest in countries with sound fundamentals and more openness to trade. In addition, they favor bonds with high past returns and yields while averting bonds with high transaction costs and idiosyncratic risks.     

Bond markets and banks in inter-war Japan

The issuance of bonds increased in inter-war Japan, the main investors being banks because the demand for loans declined in this period. Banks that were more tolerant to risk (that is, whose capital ratio was higher) made a larger amount of loans, which were riskier than bonds. While national bonds were traded actively in secondary markets, local bonds, corporate bonds, and bank debentures were not traded actively during this period. After the formation of cartels of banks and securities firms for bond underwriting and trading during the Great Depression, bond trading in secondary markets diminished, except for national bonds.     

Information asymmetry and investor trading behavior around bond rating change announcements

This study examines stock market reactions to public announcements (corporate bond rating changes), including changes in stock prices and investor behavior in terms of trading volumes and patterns. Abnormal returns, abnormal volumes, and net order imbalances are estimated using high-quality stock transaction data from Korean firms, whose bonds were rated by Korea's leading credit rating agencies between 2000 and 2015. We find positive (negative) abnormal stock returns around upgrades (downgrades), although the stock price reactions to downgrades are more statistically significant than those to upgrades. Significant abnormal volumes and order imbalances are found around rating changes, and the extent to which each investor group (domestic individuals, domestic institutions, or foreign investors) reacts to a rating change varies. Our analyses also support that foreign and domestic institutional investors are better informed than individual investors.     

Does corruption increase emerging market bond spreads?

We study the relationship between corruption and borrowing costs for governments and firms in emerging markets. Combining data on bonds traded in the global market with survey data on corruption compiled by Transparency International, we show that countries that are perceived as more corrupt must pay a higher risk premium when issuing bonds. The global bond market ascribes a significant cost to corruption: an improvement in the corruption score from the level of Lithuania to that of the Czech Republic lowers the bond spread by about one-fifth. This is true even after controlling for macroeconomic effects that are correlated with corruption. We find little evidence that investors became more sensitive to corruption in the wake of the Asian financial crisis.     

Frontier and emerging government bond markets

We investigate correlation dynamics and diversification properties of US dollar-denominated debt issued by governments of frontier markets. Our analysis is on the aggregate, regional, and country level, with a sample covering 29 countries over the period 2001–2013. We show that the correlation between the returns of frontier government bond markets and US government bonds is time-varying, but on average close to zero. Correlations with US investment grade corporate bonds, US corporate high yield bonds, and US dollar-denominated debt issued by governments of emerging markets are substantially higher, which limits diversification benefits for investors who already own these asset classes.     

The conditional relationship between beta and returns: recent evidence from international stock markets

The risk–return relationship is one of the fundamental concepts in finance that is most important to investors and portfolio managers. Finance theory argues that the beta or systematic risk is the only relevant risk measure for investors. However, many studies have showed that betas and returns are not related empirically, no matter in domestic markets or in international stock markets. This paper examines the conditional relationship between beta and returns in international stock markets for the period from January 1991 to December 2000. After recognizing the fact that while expected returns are always positive, realized returns could be positive or negative, we find a significant positive relationship between beta and returns in up market periods (positive market excess returns) but a significant negative relationship in down market periods (negative market excess returns). The results are robust for both monthly and weekly returns and for two different proxies of the world market portfolio. Our findings indicate that beta is still a useful risk measure for portfolio managers in making optimal investment decisions.     

Contingent Capital,Real Options,and Agency Costs

This paper aims to clarify how contingent convertible bond (CoCo) as a debt financing instrument affects a firm's investment policy, agency cost of debt, and capital structure. We consider endogenous and exogenous conversion thresholds, respectively. Under the exogenous case, there is an explicit optimal fraction of equity allocated to CoCo holders upon conversion, such that the agency cost reaches zero. Numerical analysis demonstrates that under an endogenous conversion threshold, CoCo induces overinvestment, a higher leverage, a possible bigger agency cost, and a stronger incentive to increase risk. But if the conversion threshold is exogenously determined, almost the opposite holds true.

Equity volatility,bond yields,and yield spreads

This study examines the impact of implied and contemporaneous equity market volatility on Treasury yields, corporate bond yields, and yield spreads over Treasuries. The CBOE VIX is the measure of implied volatility, and the measure of contemporaneous volatility is constructed using intraday squared S&P 500 returns. We find that bond yields and spreads respond to changes in equity market volatility in a manner consistent with a flight‐to‐quality effect. Both short‐ and long‐term Treasury yields fall in response to increases in implied volatility, and the yield curve flattens modestly. Yields on short‐term investment grade bonds fall in response to contemporaneous volatility shocks, while long‐term spreads on low‐quality issues widen. This indicates that investors “look ahead” in anticipation of changes in equity market volatility but respond more strongly to changes in contemporaneous market activity. © 2011 Wiley Periodicals, Inc.

Are stocks dumped or neglected by analysts' inferior investments to covered stocks?

We compare the long-term stock price and operating performance of firms that are followed by analysts to those that are not over the period of 1994-2005. While analysts are skillful in identifying quality firms for coverage, the market is efficient in pricing both covered and neglected stocks such that risk-adjusted stock returns are compatible between the two groups. However, dumped stocks consistently outperform covered stocks with significant risk-adjusted returns across different market conditions and regulatory environments. Hence, investors might earn better returns by investing in dumped stocks, but the higher returns may represent compensation for greater search costs and information risk associated with investing in these stocks.     

How sukuk shapes firm performance

With the large expansion of Islamic finance in the recent years, sukuk , which are the Sharia‐compliant substitute to conventional bonds, are now becoming more prominent. The aim of this study was to examine the impact of sukuk issuance on firm performance. To do so, we analyse how stock market performance and operating performance (OP) are influenced by issuance of sukuk and bonds on a sample of Malaysian listed companies. We consider the short‐term and medium‐term stock market reaction through the computation of cumulative abnormal returns and buy‐and‐hold abnormal returns. We investigate the impact on OP by performing regressions and by calculating abnormal operating performance (AOP) so that we can compare how issuance affects similar firms. We find that sukuk issuance generates a negative stock market reaction both in the short term and in the medium term. We also find evidence that issuing sukuk hampers OP. The analysis of AOP shows that sukuk issuers have better performance than their matched bond issuers, but that sukuk contributes to reduce the gap in performance over time. Overall, our results support the view that sukuk issuance hampers stock market performance, but that it is not attributable to a signalling effect on the bad financial situation of the issuer. We interpret our findings as evidence of adverse selection taking place on the financed projects and agency problems stemming from the specific sukuk structuring with stock market investors more reluctant to invest in sukuk issuers.     

DEFAULT AND SYSTEMIC RISK IN EQUILIBRIUM

We develop a finite horizon continuous time market model, where risk‐averse investors maximize utility from terminal wealth by dynamically investing in a risk‐free money market account, a stock, and a defaultable bond, whose prices are determined via equilibrium. We analyze the endogenous interaction arising between the stock and the defaultable bond via the interplay between equilibrium behavior of investors, risk preferences and cyclicality properties of the default intensity. We find that the equilibrium price of the stock experiences a jump at default, despite that the default event has no causal impact on the underlying economic fundamentals. We characterize the direction of the jump in terms of a relation between investor preferences and the cyclicality properties of the default intensity. We conduct a similar analysis for the market price of risk and for the investor wealth process, and determine how heterogeneity of preferences affects the exposure to default carried by different investors.     

Does governing law affect bond spreads?

Controlling for bond and issuer characteristics, bond spreads are expected to be equal across different legal jurisdictions, and differences are expected to disappear through arbitrage. However, an analysis of 490 U.S. dollar–denominated bonds issued by 53 emerging market sovereigns during 1990–2015 reveals that after the financial crisis of 2008, launch spreads of sovereign bonds issued under U.K. law have been higher than those issued under U.S. law, by 130 basis points for BB+ bonds and 175 basis points for B− bonds. This effect was not significant for investment grade bonds. On average, bonds issued under U.K. law had weaker ratings and shorter tenors post-crisis. The post-crisis impact of governing law on sovereign bond spreads is not explained by collective action clauses, or first-time bond issuances. Instead, the difference seems to be related to the perception that U.S. law offers stronger investor protection, and that the investor base for bonds issued under U.S. law is larger than that for bonds issued under U.K. law. The difference in spreads persists in the secondary market even after 180 days, perhaps because of the lack of liquidity, as investors tend to buy and hold these more attractive bonds on a longer-term basis.     

DYNAMIC PORTFOLIO OPTIMIZATION WITH A DEFAULTABLE SECURITY AND REGIME‐SWITCHING

We consider a portfolio optimization problem in a defaultable market with finitely‐many economical regimes, where the investor can dynamically allocate her wealth among a defaultable bond, a stock, and a money market account. The market coefficients are assumed to depend on the market regime in place, which is modeled by a finite state continuous time Markov process. By separating the utility maximization problem into a predefault and postdefault component, we deduce two coupled Hamilton–Jacobi–Bellman equations for the post‐ and predefault optimal value functions, and show a novel verification theorem for their solutions. We obtain explicit constructions of value functions and investment strategies for investors with logarithmic and Constant Relative Risk Aversion utilities, and provide a precise characterization of the directionality of the bond investment strategies in terms of corporate returns, forward rates, and expected recovery at default. We illustrate the dependence of the optimal strategies on time, losses given default, and risk aversion level of the investor through a detailed economic and numerical analysis.     

Arbitrage risk and the cross-section of stock returns: Evidence from China

We demonstrate that arbitrage risk, constructed using three measures — noise trader risk, trading cost and information uncertainty — can predict the return of stocks cross-sectionally in China. The findings are broadly consistent even when out-of-sample tests are conducted using the Fama-MacBeth cross-sectional regression approach. We also construct hypothetical portfolios using the information arising from arbitrage risk and find the existence of abnormal returns which is robust to the use of various portfolios constructed by re-sampling the observations through multiple approaches (e.g., by market capitalization and by book-to-market ratio). Lastly, we reconstruct our portfolios by considering the unique nature of the Chinese stock market (e.g., the dominance of individual investors). Our trading strategies again successfully obtain abnormal returns, suggesting that arbitrage risk can be useful to construct effective investment portfolios in China.     

Some factors determining municipal revenue bond interest costs

This paper tests for variations in risk premiums on municipal revenue bonds that are related to the geographic location of the issuer, the issue's second rating, and secondary collateral provisions. The empirical findings indicate that investors required risk premiums that depended on local economic conditions. Issuer borrowing costs were also shown to be related to factors that cause or reinforce segmentation of the tax-exempt bond market.     

Exchange rate fluctuations and international portfolio rebalancing

We present empirical evidence for several hypotheses of how exchange rates are affected by investors' cross-border equity portfolio rebalancing decisions. Our results are based on comprehensive, daily-frequency datasets of foreign exchange market transactions and equity market capital flows undertaken by nonresident investors in Thailand in 2005 and 2006. We find that net purchases of Thai equities by nonresident investors systematically lead to an appreciation of the Thai baht. Furthermore, higher returns on Thai equities relative to those on a reference market are associated with subsequent sales of Thai equities by foreign investors as well as a depreciation of the Thai baht, although the latter effect is not statistically significant.     

International capital flows,returns and world financial integration

International capital flows have increased dramatically since the 1980s, with much of the increase being due to trade in equity and bond markets. Such developments are often attributed to the increased integration of world financial markets. We present a model that allows us to examine how greater integration in world financial markets affects the behavior of international capital flows and financial returns. Our model predicts that international capital flows are large (in absolute value) and very volatile during the early stages of financial integration when international asset trading is concentrated in bonds. As integration progresses and households gain access to world equity markets, the size and volatility of international bond flows decline. This is the natural outcome of greater risk sharing facilitated by increased integration. This pattern is consistent with declining volatility observed during 1975–2007 period in the G-7 countries. We also find that the equilibrium flows in bonds and stocks predicted by the model are larger than their empirical counterparts, and are largely driven by variations in equity risk premia. The model also predicts that volatility of equity and bond returns decline with integration, again consistent with the data for G-7 economies.     

Risk and ex ante cost of equity estimates of emerging market firms

We examine the empirical relationship between estimates of ex ante cost of equity and risk for a sample of individual emerging market equities for the period 1990–2000. The ex ante cost of equity estimates are obtained using the residual income valuation model. As in studies that use mean realized returns on emerging market indexes, a measure of total risk (return volatility) is the most significant risk factor in explaining ex ante expected return estimates. For emerging market equities with substantial investability to global investors, global beta adds some explanatory power.     

Market Reactions to Increased Reliability of Sustainability Information

This article investigates whether investors consider the reliability of companies’ sustainability information when determining the companies’ market value. Specifically, we examine market reactions (in terms of abnormal returns) to events that increase the reliability of companies’ sustainability information but do not provide markets with additional sustainability information. Controlling for competing effects, we regard companies’ additions to an internationally important sustainability index as such events and consider possible determinants for market reactions. Our results suggest that first, investors take into account the reliability of sustainability information when determining the market value of a company and second, the benefits of increased reliability of sustainability information vary cross-sectionally. More specifically, companies that carry higher risks for investors (e.g., higher systematic investment risk, higher financial leverage, and higher levels of opportunistic management behavior) react more strongly to an increase in the reliability of sustainability information. Finally, we show that the benefits of an increase in the reliability of sustainability information are higher in times of economic uncertainty (e.g., during economic downturns and generally high stock price volatilities).
