I was wondering about that....remembered there was some gap under $4.50 that "needed filled", although I don't quite believe in that theory...would be a 100% Fib retracement to get back to $3.66...I think the push under $5 was done to trigger stop loss orders.
According to my analysis $3.66 is Buy point Now with 80% probability on inter day basis. Keep catching those falling knives. It is heroic. I would rate it right up there with self flagellation.
