TIS is definetly a L/T stock, although I'm sure there is money to be made by the day traders who know what they are doing. The products is good and has multiple applications.
I have read on another stock formum that another biotech has an alternative product hitting the market but regardless whether this will impact on TIS long term prospects, I think the market is big enough for both products.
