第三题,We will aim for generating alpha through TAA decisions which will be dependent on the successful market or factor timing rather than security selection。 依赖successful market,而不是security selection,这不就在告诉你这个是systemetic吗,哪里需要个人判断,为啥不选systemetic?

同学你好,以下是两者的定义
1. Discretionary TAA is predicated on the existence of manager skill in predicting and timing short-term market moves away from the expected outcome for each asset class that is embedded in the SAA policy portfolio
Discretionary TAA是基于投资经理的预测技巧以及择时技巧,当他预测到短期内市场变动会偏离原本SAA组合所预测的资产大类投资结果并且把握到这个偏离所发生的时间节点,那么此时所进行的TAA就是discretionary.
2. Using signals, systematic TAA attempts to capture asset class level return anomalies that have been shown to have some predictability and persistence. Value and momentum, for example, are factors that have been determined to offer some level of predictability, both among securities within asset classes (for security selection) and at the asset class level (for asset class timing).
Systematic TAA试图通过信号(signal)来捕捉到资产大类的异常收益,而且这些异常收益能够被预测并有持续性(如果anomalies根本没法预测或者只是昙花一现,也就无法以此进行TAA了)。根据技术分析来进行TAA就属于systematic TAA)
既然这里是通过对未来市场的短期预测来进行TAA,那么就是discretionary TAA
