Closing auctions set daily closing prices for U.S. stocks and account for a striking 7.5% of daily volume in 2018, up from 3.1% in 2010. We study the causes and implications of this major trend. Difference-in-difference analyses suggest that closing volume is fueled directly and indirectly by...

A model of infrequent rebalancing can explain specific predictability patterns in the time-series and cross-section of stock returns. First, infrequent rebalancing produces return autocorrelations that are consistent with empirical evidence from intraday returns and new evidence from daily...

We investigate the impact of an exogenous trading glitch at a high-frequency market-making firm on standard measures of stock liquidity (spreads, price impact, turnover, and depth) and institutional trading costs (implementation shortfall and VWAP slippage). Stocks in which the firm accumulates...

I investigate seasonalities in a set of well-known anomalies in the cross-section of U.S. stock returns. A January seasonality goes beyond a size effect and strongly affects most anomalies, which can even switch sign in January. Return seasonality exists outside of January depending on the month...

We develop measures of stock-specific trading activity based on durations of sequences of consecutive trades with fixed cumulative values. Trade sizes and signed-trade imbalances rise with activity, while price impacts generally fall, but not always, due to endogenous variation in liquidity...

We use “tick-by-tick” quote data for 39 liquid U.S. stocks and options on them, and focus on events when the two markets disagree about the stock price in the sense that the option-implied stock price obtained from the put-call parity relation is inconsistent with the actual stock price....

This paper presents direct evidence that option price quotes do not contain any information about future stock prices beyond what is already reflected in current stock prices. We use trade and quote data for 39 liquid U.S. stocks and ETFs and options on them, and focus on events when the two...
