Morgan Stanley and Credit Suisse round out the top five with identical market shares of 7.8%. These firms are the 2014 Greenwich Share Leaders in U.S. Equity Trading.

“In U.S. equities the main priority is getting paid for what you deliver,” says Greenwich Associates consultant Jay Bennett. “By maintaining their trading share in trading, some of the bulge bracket banks are now punching above their weight class in terms of their research presence. On the other hand, mid-sized brokers and research specialists that are now being paid in large part through CSAs must be careful that they are being adequately compensated for their research.”

In the increasingly important category of U.S. Equity Algorithmic Trading, the top position is held jointly by Credit Suisse, Goldman Sachs and Morgan Stanley, which are used for algo trading by 60%–64% of institutional investors.
