Well first of all if you add .17 to 3.4 you get 3.57 not 4.57. And I've explaned before about after hour trades indicating nothing. Probably some rookie using a market order during the day to buy got robbed. Never use market orders. Always use limit orders. And don't try to guess what a small after hours trade means.
Nope NNVC closed at $3.40 on Friday. Even if the aftermarket +.17 meant anything (which it doesn't) $3.40 + .17 is $3.57. Math is VERY useful as an investing tool. I will be happy to work on arithmetic with you if you'd like. Let me know.
