Great post. When i learned trading and it all clicked. ..i remember thinking how criminal shorting is to the avg joe investers. ..here let me borrow your shares and bet against you then make money when you lose money with your own god damn shares.
Diamond , pre President Clinton era, there was a "must short on an up tick" rule in place....In his time the rule was eliminated for some reason... Maybe govt needs to look at bringing the uptick rule back...under it you still can short but not to the damaging level of the current status of no price control ... IMO this would greatly eliminate the manipulation in healthcare stock prices...
