Yahoo shows AMZN stock down 87.24%

This appears to be a hack, or data corruption.

See NASDAQ's official listing ( 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.

I see it the same in my TD Ameritrade Account. Could this be an issue witht he exchange?
