Montgomery inquires whether
asset allocation models based on heuristics or other techniques might be of
interest to Winfeld and makes the following comments:
1. The 60/40 stock/bond heuristic optimizes the
growth benefits of equity and the risk reduction benefits of bonds.
2. The Norway model is a variation of the endowment model that
actively invests in publicly traded securities while giving consideration to
environmental, social, and governance issues.
3. The 1/N heuristic allocates assets equally across asset classes
with regular rebalancing without regard to return, volatility, or correlation.
In describing heuristics and other modeling techniques, Montgomery is most accurate with respect to:
选项:
A.Comment 1.
Comment 2.
Comment 3.
解释:
C is correct. The 1/N rule asset allocation heuristic involves equally weighting allocations to assets; 1/N of wealth is allocated to each of N assets available for investment at each rebalancing date. All assets are treated as indistinguishable in terms of mean returns, volatility, and correlations.
A is incorrect. It is not an optimization model. The 60/40 stock/bond heuristic allocates 60% of assets to equities, supplying a long-term growth foundation, and 40% to fixed income, supplying risk reduction benefits.
B is incorrect. The Norway model passively invests in publicly traded securities subject to environmental, social, and governance concerns. In comparison, the endowment model asset allocation emphasizes active management of large allocations to non-traditional investments, seeking to earn illiquidity premiums.
1/n投资还要rebalance吗?不是已经平分了吗?是说在rebalance date的时候可能还会有其他的available assets,所以n会 变动,所以还是需要rebalance的意思吗?
