Thats part of my question; what is to worry about if your broker confirms so long as its not a margin account buying them. In addition, even in a margin account one can not margin Hemi at the current PPS.
It may do well to remember that your broker is telling you the typical reply/answer to all requests for shares of any company. Hemi is in a unique dilemma though, and your broker may very well not be aware of it, hence in this situation, his reply may not be as accurate as he presently believes.
