The results indicate that:(i) the active portfolio structured by this decision model outperforms the benchmark portfolio;(ii) it is necessary to include the accuracy of predictability of the excess return in the decision model which enhances the return-risk profile;(iii) the model works in the market with short selling with the same excess return level and more active risk.
在中国市场条件下对决策模型进行检验,结果显示:基于该模型构造的积极组合在任何市场条件下都能够获得超越基准组合的收益;在决策模型中考虑超额收益预测准确性是必要的,提高超额收益预测的准确性有利于提高组合超额收益,同时降低组合积极风险;在允许卖空的市场条件下决策模型依然成立,组合超额收益水平未发生显著变化,但积极风险加大。
