For fixed- income investors seeking to reduce the cost of active management while
addressing systematic biases such as the bums problem, a third alternative known as
smart beta has emerged. Smart beta involves the use of simple, transparent, rulesbased
strategies as a basis for investment decisions. The starting point for smart beta
investors is an analysis of the well- established, static strategies that tend to drive
excess portfolio returns. In theory, asset managers who are able to isolate and pursue
such strategies can capture a significant proportion of these excess returns without
the significantly higher fees associated with active management. Although the use
of smart beta strategies is more established among equity managers, fixed- income
managers are increasing their use of these techniques as well
-----老师,这是书上的。 我纳闷的是smart β到底属于主动策略还是被动策略,
它和factor-based有啥区别?它怎么实施的?请举个通俗的例子
