We examine the impact of institutional trading on stock resiliency during the financial crisis of 2007–2009. We show that buy-side institutions have different exposure to liquidity factors based on their trading style. Liquidity supplying institutions absorb the long-term order imbalances in the market and are critical to recovery patterns after a liquidity shock. We show that these liquidity s...

The electronic limit-order trading system have been sweeping the exchanges around the globe since last decade. This paper studies a case of the transition, which is a group of less-liquid stocks moving to SETS on the London Stock Exchange. The evidence reveals that the liquidity of those stocks substantially drops after the move.

Are Stock Returns Different over Weekends? A Jump Diffusion Analysis of the " Weekend Effect " T he distribution of returns on common stocks is, arguably, one of the most widely studied financial market characteristics. Among the questions addressed by these studies are the following: Is the return on common stocks normally distributed, as much finance theory assumes? How many stocks should be ...

Although the understanding of and motivation behind individual trading behavior is an important puzzle in finance, little is known about the connection between an investor's portfolio structure and her trading behavior in practice. In this paper, we investigate the relation between what stocks investors hold, and what stocks they buy, and show that investors with similar portfolio structures to...

and Company LLC (GMO) uses mixed-integer-programming (MIP) methods to construct portfolios that are close (in terms of sector and security exposure) to target portfolios, have the same liquidity, turnover, and expected return as the target portfolios, control frictional costs, and do so with fewer distinct stocks and with fewer transactions. It also applies MIP methods to portfolios consisting ...

In this paper, we develop and test a theoretical model of multi-market trading to explain the differences in the foreign share of trading volume of internationally cross-listed stocks. The model derives an equilibrium which predicts that, under fairly general conditions, the distribution of trading volume across exchanges competing for order flow is related to the correlation of the cross-liste...

A developmental co-evolutionary genetic programming approach (PAM DGP) is compared to a standard linear genetic programming (LGP) implementation for trading of stocks in the technology sector. Both interday and intraday data for these stocks were analyzed, where both implementations were found to be impressively robust to market fluctuations while reacting efficiently to opportunities for profi...

Confluence occurs when different trading filters generate signals that point to the same directional move. Using regression analysis, this paper investigates confluence trading signals associated with number preference and price exhaustion, for a sample of Australian stocks. The results show that certain price levels tend to act as psychological barriers, and that price exhaustion signals are a...

We model the distribution of daily stock trading volume using the power law and document a new phenomenon. The power law exponent systematically increases with time suggesting that trading is becoming increasingly concentrated in a subset of stocks. © 2007 Elsevier B.V. All rights reserved.
