No such thing as a "HEMP Stock trading exchange." The exchange would be the NYSE or Nasdaq exchanges, mostly on the latter where most small companies start out listing their stock.

I wouldn't buy this one. It looks like a pump-&-dump to me. Look at the chart. This will fall back to the 2-5 cents range by the end of the week. The "company" has no profits nor any product. thus is not profitable.

I am interested in the company HEMP which is trading stock. I have a few questions.

1. What exchange are they trading on?

2. Where can I see the day which they went public?

3. Is there a website where I can research past IPO dates for penny stocks?

I am not by the way interested in buying into this company, just curious about there latest quick moving stock. Just doing some research. Thanks!
