Goldman Sachs’ Dark Pool Platform Upgraded with Nasdaq Technology

Goldman Sachs debuted a new dark pool last week. At first, only two stocks traded on the new platform, dubbed Sigma X-Squared, but everything else will be shifted over within about a month from the older Sigma X system. Goldman Sachs’ new dark pool will allow clients to choose which kinds of trading behaviors they want to be on the other side of. That’s opposed to Sigma X’s old system, which takes a more general approach to how clients choose who they trade with. The new pool will run on Nasdaq Inc. technology. Nasdaq is the third-largest owner of U.S. stock exchanges, and also supplies trading software to clients who want to run their own markets.
