Currency risk in emerging equity markets

The paper develops an international capital asset-pricing model (ICAPM), which includes foreign currency risk, and examines the impact of capital market liberalisation on the pricing of risks. It applies the model to data from Pacific Basin financial markets and finds substantial evidence that not only currency risk is priced in both pre- and post-liberalisation periods, but the model is superior to one which does not include currency risk. This evidence suggests that an international capital asset-pricing model, which omits currency risk, will be misspecified. Furthermore, the results imply that since currency risk is priced and investors are compensated for bearing such risk they should not be discouraged by more flexible exchange rate regimes from investing in emerging markets.     

Small traders in currency futures markets

This study examines the interrelation between small traders' open interest and large hedging and speculation in the Canadian dollar, Swiss franc, British pound, and Japanese yen futures markets. The results, based on Granger‐causality tests and vector autoregressive models, suggest that small traders' open interest is closely related to large speculators' open interest. Small traders and speculators tend to herd, which means that small traders are long [short] when speculators are long [short] as well. Moreover, small traders and speculators are positive feedback traders whereas hedgers are contrarians. Regarding information flows, speculators lead small traders in three of the four currency futures markets. The results therefore suggest that small traders are small speculators who follow the large speculators, indicating that they are less well informed than the large speculators. © 2010 Wiley Periodicals, Inc.

Clustering in emerging equity markets

We consider pairwise tail behavior of return series for identifying the most important emerging markets clusters. Pairs of markets belonging to the same group present similar type and strength of interdependence during stressful times, represented by a common copula and a statistically equivalent measure of tail dependence. By collapsing data from d markets in to a group we overcome the difficult problem of finding their (higher dimensional) d-variate distribution. Results may help portfolio managers to deal with risk due to co-movements within clusters. We provide examples on how this can be done. Our study contributes to the discussion about the international association among stock markets during turbulent periods, and does not confirm the intuition that the observed association between extremes should be credited to linkages to leading markets. The study also confirms the importance of stock selection, particularly among the non-dominant stocks, instead of holding market-value weighed portfolios of stocks from countries within the same region.     

Looking for contagion in currency futures markets

This article tests whether there are pure contagion effects in both conditional means and volatilities among British pound, Canadian dollar, Deutsche mark, and Swiss franc futures markets during the 1992 ERM crisis. A conditional version of international capital asset pricing model (ICAPM) in the absence of purchasing power parity (PPP) is used to control for economic fundamentals. The empirical results indicate that overall there are no mean spillovers among those futures markets, but they are detected during the crisis period. That is, past return shocks originating in any one of the four markets have no impact on the other three markets during the entire sample period, suggesting that these markets are weak‐form efficient. However, this weak‐form market efficiency fails to hold during the market turmoil, especially for British pound and Swiss franc, and the sources of contagion‐in‐mean effects are mainly due to the return shocks originating in three European currency futures markets. As for the contagion‐in‐volatility, it is detected for British pound only because its conditional volatility is influenced by the negative volatility shocks from Canadian dollar, Deutsche mark, and Swiss franc, with Deutsche mark playing the dominant role in generating these shocks.

Detecting shift-contagion in currency and bond markets

This paper investigates why financial market crises often increase the interdependence between assets associated with different countries. Two sources of increased co-movement in asset returns are considered: (i) larger common shocks operating through standard cross-country linkages and (ii) changes in the structural transmission of shocks across countries, referred to as “shift-contagion”. To examine this issue, we develop a method for detecting shift-contagion with three notable features. First, parameters corresponding to the structural transmission of shocks across countries are identified in the presence of changing volatility regimes for the shocks. Second, the timing of changes in volatility is endogenously estimated instead of being exogenously assigned. Third, the countries in which crises originate need not be known or even included in the analysis. We apply the method to currency returns for developed countries and bond returns for emerging-market countries.     

Investing in Asia's emerging equity markets

Asian equity markets have been hot for some time and they show no dramatic signs of cooling. The economies of the region have moved towards greater economic and financial integration while opening their capital markets to foreigners. Attracted by strong economies, credible reforms and further intentions of liberalization, global investors have made significant investments. However, the stability promised by a financially strong Japan is diminishing, and the region as a whole faces a variety of political and financial challenges.     

Average skewness in global equity markets

This paper examines the predictive power of average skewness, defined as the average of monthly skewness values across stocks, documented by the prior literature for US market returns in an international setting. First, we confirm the validity of the results in the original study and show that the intertemporal relation between average skewness and aggregate returns becomes weaker in an alternative sample period. Second, when we repeat the analysis in 22 developed non-US markets, we find that average skewness has no robust predictive power for future market returns. The loss of forecasting power in the international sample does not depend on the method used to calculate average skewness or the regression specification and is supported by additional out-of-sample tests and subsample analysis.     

Private equity exits in emerging markets

Using deal level data from 2733 private equity (PE) deals from 35 emerging markets, we find that PE fund managers have a higher probability of successful exits in countries with better business and legal environments. We also find that they are able to mitigate the potential costs associated with inefficient and corrupt business environments to increase the probability of exits by IPOs in countries with higher levels of corruption. Moreover, we find that market shocks in the developed markets result in a negative ripple effect as the probability of successful exits, especially by way of IPOs, decreases in emerging markets.     

Political conditions and currency crises in emerging markets

This article demonstrates the impact of structural political conditions on the likelihood of currency crises in emerging markets. Controlling for a standard and parsimonious set of macroeconomic variables, I find that: right-wing government is less conducive to currency crises; ‘strong’ governments (those with larger legislative majorities and those which face more fragmented legislative opposition) are also less vulnerable. Democracy also reduced the likelihood of currency crises in emerging markets; yet, in contrast to previous studies, this article does not find a significant impact of elections on the likelihood of currency crises.     

External currency pricing and the East Asian crisis

This paper provides a quantitative investigation of the East Asian crisis of 1997-1999. We stress two essential features of the crisis. First, the crisis was a regional phenomenon; the depth and severity of the crisis were exacerbated by a large decline in regional demand. Second, the predominance of the US dollar in the pricing of export goods in Asia (which we document empirically) led to a powerful internal propagation effect of the crisis within the region, contributing greatly to the decline in regional trade flows. We construct a multi-country macroeconomic model which contains these two features and show that it can do a good job in accounting for the response of the main macroeconomic aggregates in Korea, Malaysia and Thailand during the crisis. A key advantage of our model is that it can explain the very slow response of exports to the large real exchange rate depreciations that took place during the crisis. Without the regional dimension and dollar pricing of exports, we find that the model fails to account for the depth and severity of the crisis.     

Empirical performance of alternative pricing models of currency options

This article examines the out‐of‐sample pricing performance and biases of the Heston’s stochastic volatility and modified Black‐Scholes option pricing models in valuing European currency call options written on British pound. The modified Black‐Scholes model with daily‐revised implied volatilities performs as well as the stochastic volatility model in the aggregate sample. Both models provide close and similar correspondence to actual prices for options trading near‐ or at‐the‐money. The prices generated from the stochastic volatility model are subject to fewer and weaker aggregate pricing biases than are the prices from the modified Black‐Scholes model. Thus, the stochastic volatility model may provide improved estimates of the measures of option price sensitivities to key option parameters that may lead to more effective hedging and speculative strategies using currency options. © 2000 John Wiley & Sons, Inc.

Determinants of Nikkei futures mispricing in international markets: Dividend clustering,currency risk,and transaction costs

This paper develops a comprehensive modified cost-of-carry model to study the mispricing of Nikkei 225 index futures contracts traded in Osaka, Singapore, and Chicago based on a new 19-year data set. Using this improved model, we find that dividend clustering, currency risk, and transaction costs all play an essential role in the estimation of Nikkei mispricing. An exponential smooth transition autoregressive-GARCH model is used to describe the international dynamics of Nikkei mispricing. The results indicate that generally mean reversion in mispricing and limits to arbitrage are driven more by transaction costs than by heterogeneous investors.     

Liquidity and stock returns in emerging equity markets

Using data for 27 emerging equity markets for the period January 1992 through December 1999, we document the behavior of liquidity in emerging markets. We find that stock returns in emerging countries are positively correlated with aggregate market liquidity as measured by turnover ratio, trading value and the turnover–volatility multiple. The results hold in both cross-sectional and time-series analyses, and are quite robust even after we control for world market beta, market capitalization and price-to-book ratio. The positive correlation between stock returns and market liquidity in a time-series analysis is consistent with the findings in developed markets. However, the positive correlation in a cross-sectional analysis appears to be at odds with market microstructure theory that has been empirically supported by studies on developed markets. Our findings regarding the cross-sectional relation between stock returns and liquidity is consistent with the view that emerging equity markets have a lower degree of integration with the global economy.     

Local currency systemic risk

Emerging country governments increasingly issue local currency denominated bonds and foreign investors have been increasing their holdings of these assets. By issuing debt denominated in local currency, emerging country governments eliminate exchange rate risk. The growing stock of local currency government debt in the financial portfolios of foreign investors increases their diversification and exposure to fast growing economies. In this paper, we highlight some of the risks associated to this recent trend. First, we adopt the CoV aR risk-measure to estimate the vulnerability of individual countries to systemic risk in the market for local currency government debt. Second, we show that our country-level estimates of vulnerability increase with the share of local currency debt held by foreign investors. A version of the old adage “When New York sneezes, London catches a cold,” used often to describe the relationship between the stock markets in these two cities, still applies between individual emerging countries and the aggregate market for local currency government debt.     

Sector level cost of equity in African financial markets

This paper assesses the effectiveness of Liu (2006) metrics in measuring illiquidity within a multifactor CAPM pricing model. Costs of equity are estimated using this model for the major sectors within Africa's larger equity markets: Morocco, Tunisia, Egypt, Kenya, Nigeria, Zambia, Botswana and South Africa. In all countries, the cost of equity is found to be highest in the financial sector and lowest in the blue chip stocks of Tunisia, Morocco, Namibia and South Africa. At an aggregate level, Nigeria and Zambia have the highest cost of capital.     

Equilibrium pricing of contingent claims in tradable permit markets

We advance a model of the tradable permit market and derive a pricing formula for contingent claims traded in the market in a general equilibrium framework. It is shown that prices of such contingent claims exhibit significantly different properties from those in the ordinary financial markets. In particular, if the social cost function kinks at some level of abatement, the forward price, as well as the spot price, can be subject to the so‐called price spike. However, this price‐spike phenomenon can be weakened if a system of banking and borrowing is properly introduced. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 30:559–589, 2010     

After‐hours trading in equity futures markets

Although it is well known that electronic futures data absorb news (slightly) in advance of spot markets the role of the electronic futures movement in out‐of‐hours trading has not previously been explored. The behavior of the 24‐hour trade in the S&P 500 and NASDAQ 100 futures market reveals the important role of these markets in absorbing news releases occurring outside of normal trading hours. Peaks in volume and volatility in this market occur in conjunction with U.S. 8:30 A.M. EST news releases, before the opening of the open‐outcry markets, and in a less pronounced fashion immediately post‐close the open‐outcry market. Price impact in these markets is statistically higher in the post‐close than in the pre‐open periods. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 29:114–136, 2009
