3RD UPDATE, 4:14 PM:  Nasdaq now has issued a revised statement blaming today’s three-hour hiccup on “a connectivity issue,” but it adds that “The cause of the issue has been identified and addressed.” Read the full revised statement after the jump:
“Earlier this afternoon, NASDAQ OMX became aware that price quotes were not being disseminated by the Securities Industry Processor (SIP), which consolidates and disseminates all prices for the industry.

“There was a connectivity issue between an exchange participant and the SIP, which led to a degradation in the ability of the SIP to disseminate consolidated quotes and trades. The cause of the issue has been identified and addressed.

“Responding to the SIP issue, in order to protect the integrity of the markets, NASDAQ OMX issued a regulatory halt for all trading in NASDAQ-listed securities.

“In the first 30 minutes, technical issues with the SIP were resolved. For the remaining period of time, NASDAQ OMX, other exchanges, regulators and market participants coordinated with each other to ensure an orderly re-opening of trading in NASDAQ-listed securities.Trading resumed and the balance of the trading day finished in normal course.

“NASDAQ OMX will work with other exchanges that are members of the SIP to investigate the issues of today, and we will support any necessary steps to enhance the platform.”

2ND UPDATE, 2:58 PM:  Nasdaq has released a statement about today’s three-hour shutdown — basically saying it has no idea what happened. Regardless, the index finished up 38.92 (+1%) at 3638.71. Here’s Nasdaq’s release: “Earlier this afternoon, NASDAQ OMX became aware that price quotes were not being disseminated by the Securities Industry Processor (SIP), which consolidates and disseminates all prices for the industry. Responding to the SIP issue, in order to protect the integrity of the markets, NASDAQ OMX issued a regulatory halt for all trading in NASDAQ-listed securities. In the first 30 minutes, technical issues with the SIP were resolved. For the remaining period of time, NASDAQ OMX, other exchanges, regulators and market participants coordinated with each other to ensure an orderly re-opening of trading in NASDAQ-listed securities. Trading resumed and the balance of the trading day finished in normal course. NASDAQ OMX will work with other exchanges that are members of the SIP to investigate the issues of today, and we will support any necessary steps to enhance the platform.”

UPDATE, 11:53 AM: Nasdaq said it is resuming partial trading and plans to be completely back at about 3:25 ET/12:25 PT. That would make the outage more than 3 hours. The index is currently frozen up 31-plus points on the day.

PREVIOUS, 10:21 AM: The Nasdaq status message at 12:14 ET/9:14 PT alerted that trading in all securities had stopped due to a snafu with a computer feed that disseminates stock quotes. A spokesman for the exchange said, via CNBC: “Nasdaq will not be canceling open orders on the book. Customers who wish to cancel their orders may do so and any customer who wishes to not participate in the re-opening should cancel their orders prior to the resumption of trading”. The action has halted NYSE trading on all Nasdaq securities and the NYSE was cancelling orders. Nasdaq-based companies like Yahoo, Microsoft and Facebook are showing flat lines on their charts while the exchange is down. The broader markets had been enjoying an uptick today after losses the past few days, and the outage doesn’t seem to be having a negative impact with the Dow and S&P both seeing gains despite having Nasdaq-listed companies. The restart may be bumpy though. Stay tuned.
