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.

Edit: It appears several tech stocks (AAPL, MSFT, AMZN, etc.) have their prices set to 123.47. Definitely pointing to some sort of data corruption.

> all have their prices set to 123.47

Which is what you'd get if the price was 123.456789... and rounded to two decimal places.

Plausible, but wouldn't it be 123.46?

Ugh, apparently I can't math that early in the morning. :(

Please change the title instead of flagging this. It may not be a crash but this is newsworthy.

Yeah, this is some sort of horrible error on some sort of aggregator, I'd guess. MSFT did not gain 79% today, but that's what Google says. Yahoo! on the other hand, says it lost 57.74%.

If you go to schwab.com and get a quote there, it shows the correct prices, so it wasn't the exchange itself.

I can.

US Market closed early today at 1:00PM. Market data was finalized at 5:16 PM. Data sent to third parties after 5:16PM today would have been test data - they do this every day and the third party systems receive and then purge the test data. One or more third parties took at as real data, possibly because of the odd market close time, and then re-propagated those prices to the real time systems. The reason this can happen is that certain off book transactions can be/are reported by these third parties. These reports update the stock price.

Any EBAY (https://www.google.com/finance?q=NASDAQ%3AEBAY) went up 254%? No, these are just glitches with Google Finance. It happens once in a while.

Bloomberg[0] is showing the same thing, so if it's a data glitch it's not limited to just Google Finance.

I wonder what this is going to do to all the sub-second quant algorithms. Do they have the ability to recover quickly from this kind of data corruption?

Yahoo finance shows similar numbers https://finance.yahoo.com/quote/AMZN?ql=1&p=AMZN

This is a glitch not a flash crash. There is absolutely no volume on Amazon right now. This actually happens all the time .

This must be an issue with Google's data provider. Their graphs still show the correct stock price.

Can anyone share some thoughts?

How come!?

It was discovered no one actually really used Alexa

That's not true! I use it to reply to Ashley Madison fembots. (It's a vicious circle really.)
