...By adopting a more strategic method of rebalancing,
...SBCERA’s “informed rebalancing program” launched in 2006. Since then, the program has added an extra $965 million to the portfolio, or about 1.25 percent in additional returns annually, according to a case study by fund CIO Donald Pierce, Muralidhar, and AlphaEngine co-CIO Sanjay Muralidhar.
...“Instead of letting a portfolio aimlessly drift until some happenstance trigger occurs, a clearly identified staff member was tasked with taking ownership of the asset allocation decision and making adjustments in an explicit, rules-based, and informed manner,” they wrote.
The rules for portfolio rebalancing were based on peer-reviewed academic research, and focused primarily on asset valuations. Under this regime, decisions “were not arbitrarily triggered, but rather provided staff’s best estimates of which assets were over/undervalued and in turn, over/underweighted within the board-approved ranges,” according to the paper.
