This appears to be a hack, or data corruption. See NASDAQ's official listing ( http://www.nasdaq.com/symbol/amzn/after-hours http://www.nasdaq.com/symbol/amzn/after-hours ). Several other ticker symbols (AAPL, MSFT, etc.) are also affected. It appears several tech stocks (AAPL, MSFT, AMZN, etc.) have their prices set to 123.47. Definitely pointing to some sort of data corruption.
