Following On Wall Street's Top 40 Under 40 rankings from year to year, one comes to know the names of the industry's youngest and highest-producing wealth managers.

So, Stephen Barrett of J.P. Morgan should sound familiar to those who covet this annual must-read. That's because last year's No. 2 advisor, is this year's No. 1.

Barrett demonstrates how shifting his focus, in his case to more institutional business, helped not only dramatically boost his AUM, but also his total T-12 production. But that's just one may to make the cut. Contributing writer Elliot M. Kass, who wrote the introduction of our cover story, writes that the top 40 have "strikingly-diverse" business models when it comes to investment strategies and even personalities. Kass finds these advisors to be a fiercely competitive group, that exudes confidence and commands client trust.

The rankings reveal several commonalities as well. Among them, Kass writes that these advisors are risk-averse and conservative on investments, but also that "this is a group without a comfort zone" regarding practice management. "Instead, they are constantly seeking out the next challenge," says Kass.

That doesn't come as a surprise from a youthful bunch in an industry that's looking to replace an aging and more experienced workforce.  Check out this year's rankings for what it takes to be successful now, and for a flavor of what the future may hold when these younger advisors step up to replace the old guard.

On Wall Street has profiled all of the top 40 advisors. Make note of these advisors, including those whose names sound familiar, because they will surely give their all for their clients over the coming months, and hopefully to place again on next year's rankings.
