One of the benefits of Ihub is that it provides a forum to advertise your investment. If one chooses to project a positive sentiment, it may attract other potential investors to the stock which, if buying occurs, may increase the price of the stock.
Projecting a negative sentiment will likely not attract new investors, thus not leading to a price increase in the stock - maybe a decrease. This is self-defeating.
My momma told me, "if you don't have anything good to say, don't say anything at all". Don't underestimate the power that you have on Ihub.
