Penny stocks are inherently more risky, more likely to have wide fluctuations of price, more likely to be P&D scams than the more expensive stocks.
If the ASC trading ban is rescinded, it may not necessarily mean that the stock will go up, there should be more volume surely, but many in Canadian provinces who own it may be dying to bail out and sell the stock and get what ever they can.
The bottom line is the market has little interest in TSHO, after Skymark's P&D scheme and all the notoriety, to get new investors to invest will take a lot of faith. With its main product G-sprout now history, the stock is a losing proposition with just one product and one bad news after another, little wonder its stock price is spiraling down.
Having said that, by itself ASC restoration of its trading privileges may have some positive effect on its stock price but not great or enough to get it to 5 cents, but adding new products in future to its line and improving financials might.
Either way for now, over a period of time the stock has overall a far more chance of going down than up. If you are lucky to see a surge be it ASC's restoration of its trading privileges or some other perceived good news, and that can always happen, bail out for sure, and cut your losses and had over your bag to some one else.
