Update 2 (11:15am ET): The NYSE says it is continuing to investigate the “technical issue” that caused wild stock swings at the market open Tuesday as dozens of large-cap stocks suddenly plunged or spiked during the broken opening auction.
According to the New Jersey-based New York Stock Exchange, “impacted members may consider filing for Clearly Erroneous or Rule 18 claims” adding that “In a subset of symbols, opening auctions did not occur. The exchange is working to clarify the list of symbols.”

Update (9:52am ET). According to the NYSE, as of 9:48am, all systems are back to normal, although that is an understatement in a market where nobody knows what the correct opening price is! We are still waiting for the NYSE to give a detailed explanation of what caused this latest “broken markets” episode.
