Hi I went ahead and invested in a small speculative stock, Helius Medical. I did so because I really believe that their product is going to be a huge benefit to patients - I work in health care. I'm hopeful that this will translate into a good investment. This part I'm a bit iffy on. The stock is mostly "pre-revenue" / "pre FDA approval". It has been approved in Canada and they have 2 clinics up and running. FDA approval is supposed to be coming in the next few weeks (maybe longer with the shutdown - I hear the FDA is still making approvals - just slower) The stock fluctuates wildly - people I think try to drive it up and down to suit their needs - not something I am enjoying - especially since it is mostly lower since I got in - of course. I am hoping that the FDA approval will cause a nice rise in stock price. Any idea what a realistic peak would be? I have no way to make any sort of educated analysis of this stock. The ones who push this stock throw out these pie in the sky numbers that I am sure can't be based in much reality. Assuming it does rise sharply will it likely then go back down just as sharply as people take profit? If it goes back down is it likely to stay down for a long time as it is a small company just trying to get started? How can I best get out close to the top? A Limit Sell order? If so should I do this on the TSX or on NADAQ? Its a "dual traded stock" - I hear I can sell my TSX shares on NASDAQ. NASDAQ is more liquid but is this a good thing? Will more liquid help to get me a better price or if it is moving too fast will it drop to a lower price that I am hoping for? I know I can't expect any real definitive answers to most of my questions - it is a speculative investment. I'm just hoping for some good advice from people I can trust. May turn out to be a case study for why I should avoid individual stocks - but I hope not. Thanks for your help.
