The Martins wish to allocate th15% to a suportfolio with the goof making a charitable gift to their almamater from their estate. Although the gift is a low- priority goal, the Martins want the suportfolio to earn the highest return possible. Quinn promises to recommenasset allocation strategy for the Martins’ aspirationgoal.Next, Quinn scusses taxation of investments with the Martins. Their interest income is taxe35%, ancapitgains anvin are taxe20%. The Martins want to minimize taxes. Baseon personresearch, Nemakes the following two statements:Statement 1 The after- treturn volatility of assets helin taxable accounts will less ththe pre- treturn volatility.Statement 2 Assets threceive more favorable ttreatment shoulhelin tax- ferreaccounts.The equity portion of the Martins’ portfolios proceannualizereturn of 20% for the past three years. a result, the Martins’ equity allocation in both their taxable antax- ferreportfolios hincreaseto 71%, with bon falling to 29%.The Martins want to keep the strategic asset allocation risk levels the same in both types of retirement portfolios.

Following a thorough review, McCall recommen a new IPS anstrategic asset allocation. The proposeIPS revisions inclu a plfor short- term viations from strategic asset allocation targets. The gois to benefit from equity market tren automatically increasing (creasing) the allocation to equities 5% whenever the S P 500 Inx 50- y moving average crosses above (below) the 200- y moving average.The most appropriate asset allocation for the Martins’ new charitable gift sub-portfolio is: A.40% equities/60% bon. B.70% equities/30% bon. C.100% equities/0% bon. C is correct. The Martins’ suportfolio is aspirationana low priority.

In aition, the Martins want the highest return possible.Therefore, the highest allocation to equities is most appropriate.考点revising the strategic asset allocation解析原文中“making a charitable gift to their alma mater from their estate”，意思是捐赠来自于他们的遗产，因此投资期很长；并且还提到low- priority go，要求highest return，所以可以配置一些激进的投资产品，承担高风险。C100%投资股票是最合适的选择。 70/30符合长期投资、高收益，也高于60/40呢。

1、怎么看出慈善是长期目标呢？ 2、三个都超出设定的范围了啊。

    请问这题为什么不考虑60/40 (8% rebalancrange) overall SAB 和 C都超过了这个range.
