I think that you've gotten some good advice about trading so far. I'll try and answer your original question(s).
Here is what I found when I researched the company, Helius Med. Technologies, stock symbol (HSDT).
A) It's a very small company; total stock market capitalization is $160m. I'd consider anything under $1billion to be small, so this is very, very small.
B) It has 40 employees, based out of Newtown, PA (halfway between Philly and NY). Again, very very small. Upper management is probably taking the lion-sized portion of the profits (to the extent they exist--see below), so there isn't much left over for shareholders.
3) Looking at the balance sheet; they have $12m in the bank and liabilities of $17m. So, they will probably have to issue more equity at some point in the near future.
4) Thinly traded at 60,000 shares per day. It's so small (and thinly traded), that it can't be shorted. When I'm buying a speculative stock, I always look for a huge short position as these are guaranteed future buyers and a bit of a cushion against a big decline, as most nay-sayers have already driven the stock lower (or at least already voted with their short). I had a decent sized position in LOXO when it was bought out earlier this year. I wondered about the 8% short position that was on the books when the deal was announced. I'm sure that they had a very bad day when that was announced.
5) They haven't been regularly reporting income/financials, as best I can tell. This is not a good sign of a healthy company.
6) They've been listed on the stock market for 5 years and the stock has gone nowhere.
So, we have a company with 40 employees, barely profitable (if at all), with no patents, positive test results and no catalyst to drive it higher (how many years away is the FDA decision? What stage are they in testing?) . While anything is possible, I do not think that this company is very investable. I believe that there are better companies that you could find to invest in.
But, maybe they have something to offer that I'm missing. I don't know anything about their product, but you seem to like the product(s) they produce. Why do you like them? What do they do that none other does? How good is the competition (is there any competition???) Serious questions, not snarky. I'm not in health care, so I'm coming at this solely from a stock-picking point of view.
