The widely tracked Nasdaq Composite Index froze for nearly an hour Tuesday after Nasdaq OMX experienced problems transmitting data for stock-market indexes, the latest in a series of technical problems besetting Nasdaq.

Exchange officials blamed Tuesday's index outage on "a human error" rather than a computer glitch. Traders said the impact to the broader market was minimal, despite trading halts for some options contracts linked to the indexes.
