Dynamic Asset Allocation and Portfolio Rebalancing

Rebalancing, Risk Parity, and Dynamic Allocations

There are a number of reasons why asset allocators might dynamically adjust the asset mix within a portfolio. The simplest reason is that weightings have become out of line with their target allocations, which can be rectified with periodic rebalancing.  Other allocators will deploy shorter-term tactical adjustments, taking a view on near-term asset price movements. Another category of dynamic asset allocation strategies will adjust the balance between "safe" and "risky" assets, in response to market movements, in order to control downside risk.   

The bulk of the papers listed below present dynamic approaches to asset allocation within portfolios, while some discuss the closely related concepts of portfolio rebalancing and risk parity.

Manulife describes a dynamic fixed income approach that focuses upon combating volatility by steering clear of corporate bonds and focusing on highly liquid assets in combination with active risk management.

Dynamic Asset Allocation Through the Business Cycle (Oppenheimer, 2015)

The authors present a dynamic approach to asset allocation that anticipates changes in a macro regime and allocates accordingly, based upon regime-specific changes in asset risk premia.

Step Optimization and Portfolio Design (Jacobi, 2018)

Visualizing changes in portfolio allocations and adopting a stepwise approach to portfolio optimization may provide advantages over a traditional portfolio optimization process.

Some Like It Hedged (CFA Institute Research Foundation, 2018)

Should institutional investors hedge their currency exposures? A dynamic approach to downside risk mitigation might suggest so. CFA Institute Research Foundation covers all relevant aspects of the currency hedging decision in this paper.

A Tactical Asset Allocation Workflow (Axioma, 2018)

Axioma explains the relationship between strategic asset allocations and active tactical overlays attempting to either mitigate risk or add alpha in this workflow.

PORTFOLIO REBALANCING


Rebalance or Rush Hour? (Research Affiliates, Aug 2018)

Research Affiliates describes how to approach the rebalancing of portfolios in a systematic fashion, thereby improving risk-adjusted returns.

Rebalancing: why investors need to keep their balance (Schroders, Jul 2018)

The author, Daniel Selioutine, observes that regular, passive rebalancing of a portfolio (following a static benchmark allocation) generates an unintended negative exposure to the momentum factor. This eight page report examines the implications.

The Unexpected Costs of Rebalancing and How to Address Them (2014)

In this paper, the authors explore some surprising properties of rebalancing and show how a momentum overlay can improve risk and drawdown properties without reducing expected returns in a constant-mix portfolio.


RISK PARITY STRATEGIES
