Nasdaq has issued a market-wide trading halt amid what appears to be a "glitch" that sent a number of the largest Nasdaq-listed stocks to crash or spike to exactly $123.47 per share.
This move crashed the value of companies including Amazon and Apple, sparked chaos in Microsoft, while sending Zynga rocketing up more than 3000%.
As Bloomberg reports, the apparent swings triggered trading halts in some securities, according to automatically generated messages. The halts are a mechanism exchanges use to limit the impact of particularly volatile sessions. A system status alert on Nasdaq’s website said that systems were operating normally at 8:23 p.m. ET. After-market hours on Nasdaq typically last from 4 p.m. to 8:00 p.m.
In a statement, Nasdaq said the glitch was related to “improper use of test data” sent out to third party data providers, and said it was working to “ensure a prompt resolution of this matter”. In cases of any clearly erroneous data, trades made are cancelled.
As a reminder this is not the first time 'glitches' have occurred on holidays... remember gold on Thanksgiving 2014.
