We explore the cost of implicit leverage associated with an S&P 500 Index futures contract and derive an implied financing rate. While this implicit financing rate has often been attractive relative to market rates on explicit financing, the relationship between the implicit and explicit...

Endowments, foundations and individual investors considering the divestment of carbon industries need to know the potential impact on risk and return. In this paper, we analyze the cost of divesting from broad market indices. Our key findings are:• Optimized carbon-free portfolios closely...

Factor analysis of security returns aims to decompose a return covariance matrix into systematic and specific risk components. To date, most commercially successful factor analysis has been based on fundamental models, although there is a large academic literature on statistical models. While...

Wrong way risk can be incorporated in Credit Value Adjustment (CVA) calculations in a reduced form model. Hull and White (2012) introduced a CVA model that captures wrong way risk by expressing the stochastic intensity of a counterparty's default time in terms of the financial institution's...

As in the case of equities, we find that the BxR proprietary extreme risk forecasts, xShortfall and xVaR, are higher than value-at-risk and expected-shortfall...

Factor models are standards in investment management. For decades, Barra factor models have provided valuable risk forecasts and inputs for the portfolio construction process. Most uses of factor models have targeted longer horizons of months or years. However, we demonstrate in this paper that...
