Suppose you want to replicate the performance of several stock indexes, some of which are price-weighted, others value-weighted, and still others equally weighted. Describe the investment strategy you need for each of the index types. Are any of the three strategies passive, in that no portfolio rebalancing need be performed to perfectly replicate the index (assuming no stock splits or cash distributions)? Which of the three strategies do you think is most often followed by small investors? Which strategy is the most difficult to implement?
