This paper utilizes a new approach to an examination of price impacts of speculators on futures markets. It focuses initially on specially obtained data on commodity “pools,” which are large funds of money that may move quickly between and across futures markets and other financial markets;...

Some of the world’s largest futures exchanges impose daily limits on the price movements of individual contracts. Using data from three of the most active US commodity futures contracts, we show that these price restrictions are largely ineffective because traders are able to take similar...

We examine whether hedging effectiveness is affected by asymmetry in the return distribution by applying tail specific metrics to compare the hedging effectiveness of short and long hedgers using Oil futures contracts. The metrics used include Lower Partial Moments (LPM), Value at Risk (VaR) and...

The market evolution since the end of 2007 has been characterized by an increase of systemic risk and a high number of defaults. Realized recovery rates have been very dispersed and different from standard assumptions, while 60%-100% super-senior tranches on standard indices have started to...

As a byproduct of the 2007-2008 credit crunch, derivatives pricing and risk management are experiencing a dramatic transformation. Assumptions that were widely accepted not long ago, like absence of counterparty credit risk and the existence of a unique risk free curve available for every...

This paper analyses the intraday co-movements between returns on several commodity markets and on the stock market in the United States over the 1997-2011 period. By exploiting a new high frequency database, we compute various rolling correlations at (i) 1-hour, (ii) 5-minute, (iii) 10-second,...

In the classical quantitative finance literature it is assumed that there is a risk free rate at which hedgers can borrow and lend in the dynamic replication process of financial derivatives. In such a framework, under complete market conditions and absence of arbitrage opportunities, for a...

In this paper we explore the components that should be incorporated in the price of an uncolateralized derivative. We assume that one counterparty will act as the derivatives hedger while the other will act as the investor. Therefore, the derivative's price will reflect the replication costs...

For deals denominated in a single currency, different collateralization schemes imply different accrual rates for funds posted as collateral, so that we can end up with different current accounts that accrue at different rates and their corresponding discount factors. In this paper we examine...
