Pretty sure that those who were 'negative' about the stock last week and bought on the share drop were the ones who sold today.
The update is good, but its only a warm up for those to come. It was not a game changer PR, but it hinted at the ones to come that will be.
When the price did not go higher than 1.90, those who flip the stock, flipped the shares they bought from last week. IMO, they will shoot themselves in the foot when they see what they could have gotten later this year.
Predictions of high prices is one of the games those who intend to sell into a run make.
Either you are long or you are not, it will take time and in that time the price will range.
