PR's do nothing for the stock correct.
FDA moves forward would.
But PR's come quite often and have no effect.
People look over the number of outstanding shares and do the math for the pps.
Private placements and shelf offerings lower the stock pps.
But PR's don't help the pps at all.
On the flipside, if you like getting google alerts of new PR's for a company you are interested in you will be very happy here.
