J.P. Morgan, Goldman Sachs and Morgan Stanley top the list of the best equity brokers, in terms of market share in both research/advisory and trading.

That’s according to a recent report, “2017 Share Leaders in U.S. Equities,” from market consultancy Greenwich Associates. The firm noted that equity brokers are again forced to contend with a secular slowdown in trading activity that has shrunk the equity trading commission pool and reduced trading revenues. The pool of commissions earned by brokers on trades of U.S. equities contracted 11-12% last year, to an estimated $8.4 billion. That drop marked the third consecutive year of decline.

“The institutions participating in our 2017 study were predicting a 3-4% increase in the equity commission pool to nearly $9 billion by Q1 2018,” said Greenwich Associates Managing Director Jay Bennett. “By late May, however, several banks were signaling the market that the pace of trading had slowed once again, and that trading revenues were likely to disappoint—again.”
