Nasdaq OMX Group Inc. halted trading for three hours yesterday to protect the integrity of markets as a technology malfunction left some investors without stock quotes, Chief Executive Officer Robert Greifeld said in his first public remarks since the incident.

The exchange operator was in constant communication with rivals during the outage and decided to halt trading of listed stocks to prevent “information asymmetry” among traders, Greifeld said in interviews at Nasdaq’s offices with Bloomberg Television’s Betty Liu and Andrew Ross Sorkin on CNBC. Greifeld said he supports developing a backup data feed to prevent the issue from happening again.
