In the latest piece from Research Affiliates, vice-chairman and co-founder Jason Hsu looks at how substantial evidence supports cyclicality in factor returns, making them predictable.

The rapid rise and sharp decline of the A-shares market represents a massive redistribution of wealth, especially painful to uninformed investors who bought hot stocks near the peak. What should the Chinese government do now?

Every year we invite some of the investment industry’s most creative thinkers to speak about their work at the Research Affiliates’ Advisory Panel conference. Along with Nobel laureates Vernon Smith and Harry Markowitz, the speakers at our 14th annual meeting included Campbell Harvey, Richard Roll, Andrew Karolyi, Bradford Cornell, Andrew Ang, Charles Gave, Tim Jenkinson, and our very own Rob Arnott. The richness of the speakers’ presentations beggars any attempt to summarize them; I’ll limit myself to the points I found most intriguing and illuminating.

The excess return earned by the average investor in value mutual funds was meaningfully negative over a 23-year period when the funds themselves outperformed the market. Why don’t all value investors benefit from the value premium?

Forty years ago, Jack Bogle helped revolutionize our industry for the benefit of the investor.

In late April, a group of leading economists and investment practitioners assembled in La Jolla, California, for Research Affiliates 2013 Advisory Panel. Our theme this year touched on two topics that have been front-and-center in recent public debates: the risk of government intervention and the potential rationing of retirement.

As an econometrician and a fund-of-funds portfolio manager, I spend much time researching quantifiable metrics to help me identify managers who can outperform consistently. There is, in fact, a rich body of literature exploring different manager selection criteria. Academic papers have considered portfolio manager attributes, such as tenure, the CFA designation, advanced degrees, and even SAT scores; they have also examined fund characteristics, such as portfolio turnover, expense ratios, and assets under management.

Rather, by enabling the government to issue low-cost debt, it fosters undisciplined spending, says Jason Hsu, CIO of Research Affiliates, LLC in this commentary.

Research makes a compelling case that investors should rebalance their portfolios, yet most investors do not do so. Why not? The answer is less about behavioral mistakes and more about the fact that rational individuals care more about other things than simply maximizing investment returns.

Many of us in the investment management business are fond of telling our clients that "hope is not a strategy." Ironically, selling hope has worked out to be a fantastic strategy for investment managers.

It threatens to derail the economic recovery and to alter forever the heretofore path of robust growth for the developed world.Emerging economies with healthy government and household balance sheets, responsible fiscal policies, and young labor forces will be the drivers for global growth and will compete with their developed counterparts for economic and political leadership.
