Why did DWTT jump from 13 to 2000 to 13 today?

Question

Was it a glitch in nasdaq? Did people actually make/lose money over this?

Answer 1

First possibility, there is such a thing as a "bad print". This term for errors is left over from the days when prices were printed on a paper ticker tape.

Second possibility, some people put out ridiculous limit offers and bids. In an illiquid issue like DWTT, no one should never put in a market order, because it will get matched to the extreme bid/offer. And, yes, they will have to honor the trade. So, the person with the limit order makes a bundle and the person with the market order gets an expensive lesson in trading.
