This is an ignorant statement. The price dropped to be in line with the new offering price. It screws the common shareholders, but if you wanted to sell, yesterday was the day to do so. Now you might as well hold on.
This is the reason I do not use stop loss orders. It can drop very quickly and you get stopped out at the worst possible time.
We should all join together to always vote AGAINST whatever the board of directors recommends, every time. That is what I do because I know that the BOD NEVER has the common shareholder interest at heart, but what pads their OWN pockets.
