Bought into MUL last week when the sentiment in this room was cautious. Sold after the second ann. that came in just on close of trade - thought the timing was rather cynical - mood in the room was guarded so got out couldn't stand the heat and lost $200. Not too bad as far as losses go but now look where the price is, it's up and down like a yo yo? or am I a dodo! Got in to AFT instead just before their ann. yesterday. Although price dropped today as profiteers got out I think this has huge potential....just needs one more positive ann. eg. contracts with hospitals, airports etc etc. Can anyone offer opinion on this?
