Portfolio Theory for Squared Returns Correlated across time

Allowing for correlated squared returns across two consecutive periods, portfolio theory for two periods is developed. This correlation makes it necessary to work with non-Gaussian models. The two-period conic portfolio problem is formulated and implemented. This development leads to a mean ask price frontier, where the latter employs concave distortions. The modeling permits access to skewness...

0 Multifractal returns and Hierarchical Portfolio Theory ∗

We extend and test empirically the multifractal model of asset returns based on a multi-plicative cascade of volatilities from large to small time scales. Inspired by an analogy between price dynamics and hydrodynamic turbulence [Ghashghaie et al., 1996; Arneodo et al., 1998a], it models the time scale dependence of the probability distribution of returns in terms of a superposition of Gaussian...

Multi-Period Mean-Variance Portfolio Selection with Uncertain Time Horizon When Returns Are Serially Correlated

We study amulti-periodmean-variance portfolio selection problemwith an uncertain time horizon and serial correlations. Firstly, we embed the nonseparablemulti-period optimization problem into a separable quadratic optimization problemwith uncertain exit time by employing the embedding technique of Li and Ng 2000 . Then we convert the later into an optimization problem with deterministic exit ti...

Expected Returns Across Time Scales

This paper studies the role of ‡uctuations in the aggregate price-earning ratio at di¤erent time scales for predicting stock returns and explore the channels through which returns are predicted. Using U.S. quarterly and international monthly data, we …nd that cycles in the price-earning ratio are strong and better predictors of future returns at short and intermediate horizons than the aggregat...

Correlated Trading and Returns

A German broker’s clients place similar speculative trades and therefore tend to be on the same side of the market in a given stock during a given day, week, month, and quarter. Aggregate liquidity effects, short sale constraints, the systematic execution of limit orders (coordinated through price movements) or the correlated trading of other investors who pick off retail limit orders do not fu...
