Order Statistics for Value at Risk Estimation and Option Pricing
We apply order statistics to the setting of VaR estimation. Here techniques like historical and Monte Carlo simulation rely on using the k-th heaviest loss to estimate the quantile of the profit and loss distribution of a portfolio of assets. We show that when the k-th heaviest loss is used the expected quantile and its error will be independent of the portfolio composition and the return functions of the assets in the portfolio.
A VaR-based Model for the Yield Curve
An intuitive model for the yield curve, based on the notion of value-at-risk, is presented. It leads to interest rates that hedge against potential losses incurred from holding an underlying risky security until maturity. This result is also shown to tie in directly with the Capital Asset Pricing Model via the Sharpe Ratio. The conclusion here is that the normal yield curve can be characterised by a constant Sharpe Ratio, non-dimensionalised with respect to √T, where T is the bond maturity.
A Conditional Valuation Approach for Path-Dependent Instruments
This paper focuses on the methodology for calculating the potential future exposure of path-dependent derivative instruments.
Six Degrees of Idiocy
One of the classic works of poker, and risk management, is Herbert Yardley’s 1957 best-seller 'The Education of a Poker Player, Including Where and How One Learns to Win'. Aaron Brown explores how in both poker and finance an individual’s strategic idiocy can be quantified and analyzed.

VaR as a Percentile
In this white paper Dr. Richard Diamond expands on the concept of Value at Risk (VAR) from a formula based on the critical value, to its true definition of being a property of the joint probability distribution of risk factors.
