Abstract:
We conduct performance tests of the recommended asset allocations made by a panel of international investment houses (the "Houses") from 1982 through 2005. We compare the returns and Sharpe Ratios from the recommended-weight portfolio against those of several benchmark portfolios and to a set of 10,000 returns and Sharpe Ratios from randomly shuffled-weight and shuffled-weight change portfolios. We find that the Houses generally fail to outperform the benchmarks. The shuffled-weight change benchmark exhibits a robust "style-preserving" property in that the average portfolio standard deviation is nearly equal to the portfolio standard deviation from the actual recommended weights.
