Uhuh, I think one is Sunday or something.
Anyway, I sent this one to IR, but what do you think is the significance of the SL-401 presentation, given that the abstract is out and conclusions are out? Just because there will be a PR of things we already know?
Wouldn't it be actually greedy when others are fearful? Or was Ackman betting that VRX would go down now?
Naked shorting is legal. Failing to deliver is legal as well -- your broker may get sanctioned if they cannot find shares to deliver, in that case: neither they nor their customers will be able to naked short that stock until all fails to deliver are rectified. This is covered under SEC Rule 204.
I could be wrong, but it's possible that TDAmeritrade has the same policy, though maybe you never actually tripped it before. Every stock broker should have the same policy because PDT is governed by FINRA regulations.
