The paper studies the effect of growing mutual fund and ETF ownership on the commonality in liquidity of underlying bonds. Unpredictable liquidity needs of funds may give rise to correlated trading across underlying illiquid bonds. I document that there is a positive and significant relationship...

The interplay between investors' demand and providers' incentives has shaped the evolution of exchange-traded funds (ETFs). While early ETFs offered diversification at low cost, later ETFs track niche portfolios and charge high fees. Strikingly, over their first five years, specialized ETFs lose...

This study provides early evidence on the performance of passively-managed hedged exchange-traded funds (HETFs) introduced rather recently in late 2006. The data covers surviving HETFs in 2017 under global macro and long-short classifications. Using Fung and Hsieh's (2004) 7-factor model and...

We document economically large momentum profits when sorting ETFs on returns over the past two to four years. A value-weighted, long-short strategy based on ETF momentum delivers Carhart (1997) four-factor alphas of up to 1.20% per month. Neither cross-sectional stock momentum nor co-variation...

Exchange-traded funds (ETFs) are commonly regarded as an efficient, low-cost alternative to actively managed mutual funds, yet their perceived superiority is largely anecdotal. We evaluate the performance of a comprehensive, survivorship bias-free sample of US equity ETFs following the same...

Extant research provides evidence for financial innovation’s contribution to market efficiency by documenting that hedge funds which bet on positive earnings surprises manage their sector risk by shorting industry exchange-traded funds (ETFs). We add to this literature by considering a...

Market liquidity is expected to facilitate arbitrage, which in turn should affect the liquidity of the assets traded by arbitrageurs. We study this relationship using a unique dataset of equity and bond ETFs compiled from big trade-level data. We find that liquidity is an important determinant...

The exchange-traded fund (ETF) market has become the most important development of the financial markets over the last decade. I show that the network of the ETF market — the linkages between ETFs based on portfolio weights — catalyzes the propagation of price dislocations, the gaps between...

Short selling exchange-traded funds (ETFs) has become a common means of speculating or hedging in response to pessimistic expectations about a specific market or sector, as the short interest of ETFs is more than 10 times that of individual stocks, on average. We determine that sector-based ETFs...

This paper is the first to characterize the intraday performance of leveraged exchange-traded funds (ETFs), for which I introduce a superior volatility estimator for high-frequency analysis. Leveraged ETFs, which attempt to reproduce two or three times the daily performance of their underlying...
