同学你好
请见原文
Constructing and managing a security market index is similar to constructing and managing a portfolio of securities. Index providers must decide the following:
1 Which target market should the index represent? 确认目标市场,国内/国外?大盘/小盘?
2 Which securities should be selected from that target market? 在目标市场中选择个股
3 How much weight should be allocated to each security in the index? 如何加权?等权重/价格/市值
4 When should the index be rebalanced? 什么时候权重做再调整?
5 When should the security selection and weighting decision be re-examined? 什么时候做reconstitution?
主要是三步:
1. 选定目标市场和个体股票
2. 选定加权和编制方法
3. rebalancing and reconstitution
