Claims5
A computer-implemented method of creating and maintaining a stock index, each stock in the index meeting predefined criteria, the method comprising:
- (a) defining a predetermined time horizon and inputting the predetermined time horizon into a processor;
- (b) dividing the time horizon into a plurality of time periods;
- (c) for each new time period, selecting a packet of shares of stocks for the index that meet the predefined criteria and inputting the packet of shares into the processor;
- and
- (d) executing a software program in the processor that defines the shares of stock represented in the index as being the cumulative total of packets for the previous predetermined time horizon.
