It will only be another blow if they do not learned their lesson well. I believe there are two kinds of prediction based investors. The first is the one who followed predictions blindlessly and the other one is the kind that verify the validity of the prediction. For sure the first one will suffer another blow since they just invest on whatever they heard, whether it is just a rumor or a fact. While the second one will more likely evade the blow because he is keen on observation and can follow the validity of the prediction on the market.
