Stocks and bonds: Flight-to-safety for ever?

Stocks and Bonds over the Life Cycle

Do Hedge Funds Outperform Stocks and Bonds?

H funds’ extensive use of derivatives, short selling, and leverage and their dynamic trading strategies create significant nonnormalities in their return distributions. Hence, the traditional performance measures fail to provide an accurate characterization of the relative strength of hedge fund portfolios. This paper uses the utility-based nonparametric and parametric performance measures to d...

Risk and performance optimization for portfolios of bonds and stocks

We explain how to optimize portfolios of bonds and stocks with respect to the Expected Shortfall (ES), respectively RORC or RORAC based on ES. In a pragmatic approach we combine and correlate a stock market model with geometric brownian motions with a two-factor Cox-Ingersoll-Ross (CIR-2) model for the interest rates/bonds. We use recent results from the theory of risk capital allocation, perfo...

Shock Effects on Stocks, Bonds, and Exchange Rates

Tick data and newswire searches are used to find events that led to large and rapid changes in a stock future, a bond future, and three exchange rate futures. Knowledge of these events may be useful in future work. They have the advantages that they are truly surprises and that the sign of their effect on each financial market is known. The events are used in this study to analyze the effects o...

Bounds and Asymptotics for Planning Critical Safety Stocks

We develop bounds and approximations for setting base-stock levels in production-inventory systems with limited production capacity. Our approximations become exact as inventories become critical, meaning either that the target service level is very high or the backorder penalty is very large. Our bounds apply even without this requirement. We consider both single-stage and multi-stage systems....
