Smith is the financial advisor to Steve Hernandez and Michael Lee. Hernandez is a 35-year old physician with an annual income of $200,000 and financial wealth of $250,000. Hernandez’s financial wealth is expected to significantly increase to $1,000,000 over the next 2 months due to an inheritance. Michael Lee is a 35-year old equity trader with an average annual income of $200,000. Lee’s income exhibits a 0.90 correlation to the performance of the S&P 500.

Recommend which of the following portfolio construction strategies are optimal for Hernandez and Lee and justify the selections.

Allocation        Strategy A        Strategy B        Strategy C        Strategy D        Strategy E
Stocks              100%        80%        65%        20%        0%
AAA-rated government bonds        0%        20%        35%        80%        100%

answer:
Strategy C is optimal for Hernandez. The optimal allocation to the risk-free asset increases with initial wealth. Wealth is defined as both financial wealth and human capital. An increase in financial wealth not only increases total wealth but also reduces the percentage of total wealth represented by human capital. In this case, human capital is less risky than the risky asset. When initial wealth is low, human capital dominates total wealth. For a typical investor whose human capital is less risky than the risky asset, the optimal asset allocation is more conservative the more financial assets the investor has.

Strategy B is optimal for Lee. The optimal allocation of financial wealth becomes more weighted towards risk-free assets, than would otherwise be indicated based on age, as income and stock market returns become increasingly correlated. A higher correlation between human capital and the stock market results in less diversification and higher risk for the total portfolio. To reduce this risk, an investor must invest more financial wealth in the risk-free asset. At a 0.90 correlation between Lee’s human capital and the stock market, the optimal allocation is 20% to the risk free asset and 80% to stocks. Lee’s allocation of 80% to stocks is higher than might be expected given the correlation between his income and the S&P 500 because of behavioral factors. He is an equity trader and is likely to believe he knows stocks and to have a relatively high degree of risk tolerance. Assuming weaker correlations between his income and the S&P 500, the allocation to the risk free asset will be lower and allocation to stocks will be greater.

不觉得80%和65% allocation to equity有多大差别。  别扣细节了，排除极端的选项，剩下的感觉哪个好就哪个
