Our objective in this paper is to examine whether one can use option-implied information to improve the selection of mean-variance portfolios with a large number of stocks, and to document which aspects of option-implied information are most useful for improving their out-of-sample performance....

Individual investors have an incredible variety of sources for investment guidance. These include internet blogs, financial publications, books, newsletters and, of course, television shows. We examine a relatively new but widely popular source of investment advice, buy and sell recommendations...

We present conditions under which positive alpha exists in the realm of active portfolio management - in contrast to the controversial result in (Jarrow (2010) which implicates delegated portfolio management by surmising that positive alphas are illusionary. Specifically, we show that the...

In this paper, we outline a randomization of the primary fixed income notions. We present a construction of some stochastic interest rate models. We also consider forward rates which are implied by stochastic bond prices. We highlight to major drawbacks of the commonly used stochastic models....

We investigate risk averse agents who manage risk by trading financial securities in a market that we call a risk market. We assume this market is perfectly competitive and complete. When risk aversion is expressed using risk measures, the (bundle of) prices for financial securities turns out to...

We explore the effects of fat tails on the equilibrium implications of the long run risks model of asset pricing by introducing innovations with dampened power law to consumption and dividends growth processes. We estimate the structural parameters of the proposed model by maximum likelihood. We...

Investors utility has been mathematically modeled at 1738 by Daniel Bernoulli as an attempt to capture investors preferences to lottery outcomes. Ever since the analysis of decision making under uncertainty has again become a major focus of interest. Kahneman and Tversky in 1979 suggested a more...

The Black-Scholes theory for a portfolio with an arbitrary number of shares, x, is expanded for the case of finite liquidity. The analytical results are derived for linear market impact. As in the case of infinite liquidity (Schmidt, 2003), the arbitrage-free condition yields option price that...

We derive the total variance risk premium for an index in the stochastic environment of Driessen, Maenhout and Vilkov (2009) and correct the previous authors omission of certain components which contribute significantly to index option expected returns. This study provides a mathematically...

The foundation for a long-term investment strategy is rebalancing to fixed asset class positions, which are determined in a one-period portfolio choice problem where the asset weights reflect the investor's attitude toward risk. Rebalancing is a counter-cyclical strategy that has worked well...
