The RSM US Middle Market Business Index (MMBI) posted a record high of 132.1 in the second quarter. This is the second consecutive record-high reading for the index and reflects underlying improvement in economic conditions during the past year, as well as strong corporate earnings and respondent expectations for significant tax reform and regulatory relief this year.
Since the first quarter of 2015, RSM has collected data on middle market firms through quarterly surveys administered by Harris Poll. The survey is conducted four times a year, in the first month of each quarter: January, April, July and October. The survey panel, the Middle Market Leadership Council, consists of 700 middle market executives, and is designed to accurately reflect conditions in the middle market. The data for each quarter are weighted to ensure that they correspond to the U.S. Census Bureau data on the basis of industry representation.
A reading above 100 for the MMBI indicates that the middle market is generally expanding; below 100 indicates that it is generally contracting. The distance from 100 is indicative of the strength of the expansion or contraction.
