While stocks are still in the grips of a bear market, growth in the wealth management industry remains robust, and independent firms are taking a larger share of that growth. RIAs now make up about 30% of U.S. assets under management, double the market share of 15 years ago, according to private-equity firm LLR Partners. The firms in Barron’s annual Top 100 RIA Firms ranking now manage a combined $2.6 trillion in client assets—more than 40% of all the assets managed by U.S. independent firms.
