Do Reits Outperform Stocks and Fixed-Income Assets? New Evidence from Mean-Variance and Stochastic Dominance Approaches

Do Reits Outperform Stocks and Fixed-Income Assets? New Evidence from Mean-Variance and Stochastic Dominance Approaches

Chiang, Thomas Chinan, Lean, Hooi Hooi and Wong, Wing-Keung, (June 1, 2007)

Abstract:
This paper re-examines the performance of REITs, stocks, and fixed-income assets based on the preferences of risk-averse and risk-seeking investors using mean-variance and stochastic dominance approaches. Our findings indicate no first-order stochastic dominance and no arbitrage opportunity among these assets. However, our stochastic dominance results reveal that in order to maximize their expected utility, the risk-averse prefer fixed-income assets over real estate, which, in turn, is preferable to stocks. On the other hand, to maximize their expected utility, all risk-seeking investors would prefer to invest in stocks than in real estate, but real estate, in turn,is preferable to fixed-income assets.

Opportunistic Rebalancing: A New Paradigm for Wealth Managers

Opportunistic Rebalancing: A New Paradigm for Wealth Managers

Gobind Daryanani CFP®, Ph.D., FPA Journal (January, 2008)

Executive Summary

  • Wealth managers traditionally rebalance portfolios quarterly or annually to control risk due to asset class drifts. This paper proposes a new paradigm for planners: rebalance less frequently, but look more frequently to find the best opportunities for rebalancing.
  • The proposed approach, called opportunistic rebalancing, not only controls portfolio drift, but also provides significant return improvements by capturing buy-low/sell-high opportunities as asset classes sporadically drift relative to each other.
  • The paper studies a wide range of market conditions to show that rebalancing return benefits can be more than doubled compared with the traditional annual rebalancing.
  • These additional benefits, attributed to transient momentum and mean reversion effects, occur sporadically in time and can only be captured by monitoring portfolios frequently.
  • The studies suggest these practical guidelines: (1) use wider rebalance bands, (2) evaluate client portfolios biweekly, (3) only rebalance asset classes that are out of balance—not classes that are in balance, and (4) increase the number of uncorrelated classes used in portfolios.
  • The studies show that trading costs and tax deferral are small compared with rebalance benefits.
  • Opportunistic rebalancing has already been adopted by a number of leading wealth management firms across the country.
