Alpha Beta Separation

It is mentioned that to attain alpha beta separation for the case where Long-short strategy is not allowed, investors can use equity futures. Can someone explain with an example how this can be done? - bn

Use all of your $ to buy stocks in the same allocation as they are in the index. This will give you beta. Then, based on your capital market expectation, enter long/short position into equities futures. This will will give you additional alpha. Hope this helps. - sticky
