it is odd that HLF said they will happily answer anyone's questions regarding the company, and now they are not answering Ackman's well thought out questions.
it is in HLF's best interest to respond if they care at all about shareholder value.
Actually because Ackman is short does NOT mean he does not own any long shares.
He has EVERY right to ask questions and demand answers. The company has every right not to answer and then the stock will go down because of it. In this scenario Ackman wins.
