On Wall Street annually ranks the industry's top young producers under age 40 at the leading regional brokerage firms. In a highly competitive business, these planners have helped grow their firms and served their clients. Some are longtime employees at their regional BD while others started their careers at wirehouses and transitioned their practices to new environs.

Finalists for the ranking had to be no older than 39 as of Dec. 31, 2017 and be employed at the regional broker-dealers. Production totals were used to determine the rankings.
