Only one trade of 200 shares at $3.78. Total of only 800 shares were traded after hours and the previous 600 shares traded above $4.12/sh. Don't know who would sell their 200 shares at such a low price.
Undoubtedly, some poor fool put an AH sell order in "at market". Poor ignoramous just lost around 50 bucks, lol - from his/her account. Sad, but probably an old person or a newbie - My condolences if so. However, it's meaningless to the stock open tomorrow; over 1 million shares traded hands above 4.00 today and it would appear that she closed at the high of the day.
