A metric that assumes an even distribution of supply, demand and revenue among all properties in a selected group. An index of 100 indicates a property has achieved its fair share. For example, if a subject hotel’s ADR is $50, and the ADR of its competitive set is $50, the subject hotel’s total index is 100. If the subject hotel’s ADR totals $60, its index is 120, indicating the hotel has captured more than its expected share. If the subject hotel’s ADR totals $40, its index is 80, indicating the hotel has captured less than its expected share.
