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...

High-frequency trading has become a dominant force in the U.S. capital market, accounting for over 70% of dollar trading volume. This study examines the implication of high-frequency trading for stock price volatility and price discovery. I find that high-frequency trading is positively...

This paper investigates whether realized and implied volatilities of individual stocks can predict the cross-sectional variation in expected returns. Although the levels of volatilities from the physical and risk-neutral distributions cannot predict future returns, there is a significant...

Fundamental indexing based on accounting valuation has drawn significant interest from academics and practitioners in recent times as an alternative to capitalisation weighted indexing based on market valuation. This paper investigates the claims of superiority of fundamental indexation strategy...

This paper examines the relationship between volatility and the probability of occurrence of expected extreme returns in the Canadian market. Four measures of volatility are examined: implied volatility from firm option prices, conditional volatility calculated using an EGARCH model,...

We show that, in a frictionless and efficient market, an asset pricing model that better describes investors' behavior should better forecast stock index returns. We propose a dividend model that predicts, out-of-sample, 31.3% of the variation in annual dividend growth rates (1976-2015)....

While many studies analyze the impact of scheduled macroeconomic announcements on equity market volatility, few focus on the impact on option implied volatilities. In this study, we examine the link between German and U.S. macroeconomic events and the implied volatility indices VDAX and VIX. We...

We document a significant positive relation between earnings announcement idiosyncratic volatility and stock returns in the 10-day window before future earnings announcements. The average of risk-adjusted return differences between stocks with the highest earnings announcement idiosyncratic...

We zero in on the expected returns of long-short portfolios based on 120 stock market anomalies by accounting for (1) effective bid-ask spreads, (2) post-publication effects, and (3) the modern era of trading technology that began in the early 2000s. Net of these effects, the average anomaly's...

At the dawn of a potential rise in rates triggered by Central Banks in both Europe and the United States, doubts are being raised about the ability of low-volatility portfolios to continue to deliver robust performance. We quantify this latent performance lag and provide empirical explanations,...
