NO.PZ2018110601000024 问题如下 The SH University Enwment is a very large tax-exempt funfinancefrom stunts’ tuition fee, with the current strategic asset allocations presentebelow. The manager of Enwment forecast the expecteexcess return of eaasset class. In orr to capture the short-term return opportunities, the Enwment can: increase the allocation of private equity to 15% ancrease the allocation of reestate to 5%. increase the allocation of small-cequities to 32% ancrease the allocation of large-cequities to 38% crease the allocation of large-cequities to 40% anincrease the allocation of short-term bon to 12%. A is correct. 考点：tactical asset allocation 解析：应当增加excess return高的资产比重，降低excess return低的资产比重。但是权重变化不能超过target weight的上下限。 这是一家非常大的enwment 暗示资产规模可能很大，投资也很大， 现在他们要做TATAA是short term viation from SA 而A虽然买到了上下限，但是PE anreestate都是不容易在短期变现的资产，很可能想做TAA却因为illiqui问题根本无法实现。 应该选虽然没有买到上下限， 但是都是流动性较高的资产， 容易以更低的成本实现TAA目标。
