Note:  The selection strategy consists of sorting services by pricing performance in the first year of the pair (1995) and grouping services by quantiles (thirds and fourths).  Next, the average pricing performance for each quantile is computed for the first year of the pair. Then, the average pricing performance of the quantiles formed in the first year is computed for the second year of the pair (1997). Pricing performance measures (rank, price, and return) are compared only for services with track records in both years.  Returns are based on the 24-month average cash price benchmark, with the return for each service computed as the continuously-compounded rate of return (natural logarithm of the ratio of net advisory price to the benchmark price).
