This paper studies a dealer that pre-hedges anticipated potential trades and analyses how this impacts the client's overall execution outcomes. We show that pre-hedging can benefit both parties: improved risk management enables the dealer to charge reduced spreads that more than offset any...

Providing liquidity in over-the-counter markets is a challenging under-taking, in large part because a market maker does not observe where their competitors quote, nor do they typically know how many rivals they compete with or what the trader's overall liquidity demand is. Optimal pricing...

Over the past few years, commodity prices have experienced the biggest boom in half a century. In this paper we investigate whether it is possible by active asset management to take advantage of the unique risk-return characteristics of commodities, while avoiding their excessive volatility. We...

Recent finance research that draws on behavioral psychology suggests that investors systematically make errors in forming expectations about asset returns, and thus that investor sentiment can have predictive power for asset returns. A number of empirical studies using both market and survey...

Price signatures are statistical measurements that aim to detect systematic patterns in price dynamics localized around the point of trade execution. They are particularly useful in electronic trading because they uncover market dynamics, strategy characteristics, implicit execution costs, or...

The drift burst hypothesis postulates the existence of short-lived locally explosive trends in the price paths of financial assets. The recent US equity and treasury flash crashes can be viewed as two high profile manifestations of such dynamics, but we argue that drift bursts of varying...

This paper shows that jumps in financial asset prices are often erroneously identified and are, in fact, rare events accounting for a very small proportion of the total price variation. We apply new econometric techniques to a comprehensive set of ultra high-frequency equity and foreign exchange...

In this paper we study the multivariate return properties of a large variety of commodity futures. We find that between commodity groupings (such as metals, energy, etc.) correlations are very low and mostly insignificant whereas within groups they tend to be much stronger. In addition,...

Dealers in over-the-counter financial markets provide liquidity to customers on a principal basis and manage the risk position that arises out of this activity in one of two ways. They may internalise a customer's trade by warehousing the risk in anticipation of future offsetting flow, or they...
