It`s way harder to get funding as a private company. The playing field on start up bio`s would thin out dramatically if they were all private. The system is terrible the way it is today,so we can only hope that some changes are made to help insulate the start ups from the HFT vultures. Shorting them should be forbidden,until they`re viable with revenue from an approved drug,to start with. i think the uptick rule on shorting would help,but not enough to stop the HFT`s from doing what they can do to the specs now. Shorting them is the problem,,that`s the big sin that needs to be corrected,IMO.
