We link equity and treasury bond markets via an informational channel. When macroeconomic state shifts are more probable, informed traders are more likely to have valid signals about fundamentals, so that uninformed traders are less willing to trade against informed ones. This implies low volume...

Given the lack of any clear evidence on the informational contributions of market intermediaries vis-agrave;-vis their clients in the extant literature, an important but unanswered question is whether intermediaries behave as passive traders or whether they actively seek and trade on information....

Daily returns for stocks listed on the New York Exchange (NYSE) are not serially dependent. In contrast, order imbalances on the same stocks are highly persistent from day to day. These two empirical facts can be reconciled if sophisticated investors react to order imbalances within the trading...

In this paper, we focus on a previously unexplored but an intuitive measure of trading activity: the aggregate daily order imbalance, buy orders less sell orders, on the NYSE. Order imbalance increases following market declines and vice versa, which reveals that investors are contrarians on...

Exchange officials and policymakers are interested in whether high frequency trading causes excessive price fluctuations and whether to impose circuit breakers in financial markets to combat such fluctuations. We review the literature on these topics and draw some conclusions on the likely...

Little is known about the joint dynamics of volume across the various contingent claims on the equity market. We study the time-series of trading activity in the cash S&P 500 index and its derivatives (options, the legacy and E-mini futures contracts, and the ETF), and consider their dynamic...

We explore the premise that the degree of market efficiency changes dynamically as investment funds face time-varying funding constraints to arbitrage capital. We show that the returns to a composite long-short hedge strategy that encompasses relative value, momentum, short-run reversals, and...

We estimate buy- and sell-order illiquidity measures (lambdas) for a comprehensive sample of NYSE stocks. We show that sell-order liquidity is priced more strongly than buy-order liquidity in the cross-section of equity returns. Indeed, our analysis indicates that the liquidity premium in...

Feedback from stock prices to cash flows occurs because information revealed by firms' stock prices influences the actions of competitors. We explore the implications of feedback within a noisy rational expectations setting with publicly listed and private firms. In our setting, stock prices are...

We examine whether the recent regime of increased liquidity and trading activity is associated with attenuation of prominent equity return anomalies due to increased arbitrage. We find that the majority of the anomalies have attenuated, and the average returns from a portfolio strategy based on...
