Among the stylized features of international equity markets is the pronounced asymmetric nonlinear dependence and upward trend in correlations. Such features call into question investors' efforts to diversify internationally. We propose a model to capture those well understood characteristics of international equity index returns. Casting them in a dynamic portfolio problem, we evaluate the gains for a home-biased investor from including foreign assets in her portfolio. We find that accounting for the optimal dynamic demand for hedging on top of a standard mean-variance portfolio policy brings substantial benefits from international portfolio exposure. Such benefits become increasingly sizeable over long investment horizons. [less ▲]

It is well documented that correlation between international equity indices has trended upward for many years. This trend has called the concept of diversification into question. In this paper we argue that this argument is informed mainly by restrictions in modeling choices or portfolio solutions. We examine the fundamental question of whether there is economically significant gain of international exposures in the investment portfolio after capturing stylized dynamics of the data for short- and long-term return horizons and after accounting for intertemporal hedging. The answer is yes and the gain is substantial over a long horizon and for a reasonable range of international equity indices. First, a diversifying investor benefits from periods of low correlations of higher moments and time variations in return co-movement measures. Second, the cost of home bias comes primarily from not hedging changes in correlation and tail risks present in data, and cannot be solely explained by mean-variance considerations. [less ▲]

We study first-mover advantages in the hedge fund industry by clustering hedge funds based on the type of assets and instruments they trade in, sector and investment focus, and fund details. We find that early entry in a cluster is associated with higher excess returns, longer survival, higher incentive fees and lower management fees compared to funds that arrive later. Moreover, the latest entrants have a high loading on the returns of the innovators, but with lower incentive fees, and higher management fees. Cross-sectional regressions show that the out-performance of innovating funds are declining with age. The results are robust to different parameters of clustering and backfill-bias, and are not driven by the possible existence of flagship and follow-on funds. Our results show that the reported characteristics of hedge funds can be used to infer strategy-related information and suggest that specific first-mover advantages exist in the hedge fund industry.

Hedge funds are known to have liquidity-timing capability, but this might be conditional on aggregate market conditions. To test this, we analyze changes in the relation between hedge funds' stock market exposure and aggregate stock market liquidity. Employing an optimal changepoint approach, we find that equity-oriented hedge funds display a significant shift in liquidity-timing behavior after the major market microstructure changes in the year 2000. The shift is from a negative relation between market beta and liquidity towards a positive relation. We rule out a mechanistic explanation of the results by computing the returns to several familiar risk arbitrage strategies, finding in them no evidence of a similar shift in liquidity timing.

This paper sets the background for the Special Issue of the Journal of Empirical Finance on the European Sovereign Debt Crisis. It identifies the channel through which risks in the financial industry leaked into the public sector. It discusses the role of the bank rescues in igniting the sovereign debt crisis and reviews approaches to detect early warning signals to anticipate the buildup of crises. It concludes with a discussion of potential implications of sovereign distress for financial markets. [less ▲]

Using an optimal changepoint approach, we find a structural change in the relation between hedge funds’ stock market exposure and aggregate stock market liquidity that takes place in the period 2000 to 2002. Before the structural break, market betas have no relation to liquidity and only a few style categories of hedge funds show increased market presence when liquidity is low. After the break, the relationship is inverted, pointing towards an increased liquidity timing ability of hedge funds, as users of liquidity. We relate our findings to best execution rules and decimalization in the US stock market that were introduced in that period and impacted aggregate liquidity conditions. Furthermore, the returns to a momentum strategy display a similar structural break and momentum-loading funds constitute a sizeable proportion of hedge funds that manifest a distinct beta-liquidity evolution with a structural break in that period.
