Sure there is. The day traders just saw the value increase 9% the other day so there is some profit taking. You have to be patient with NVIV, and consider a number of factors before investing in this stock. This is not - despite the company's potential - a "get rich quick" opportunity. This is, at this stage, still an OTC stock with no earnings and no profit. Investing on the basis of the fundamentals in this case will not work for institutional investors. You have to read between the lines to get an idea as to how things will go here. In my case, I visited their web site and poked around. In the "Career Opportunities" section, there was a posting for a "Regulatory Compliance Officer." Now... why would NVIV be looking for one of those? FDA approval on the horizon?
