Denison Mines

I'm new to Denison having bought in on what appears to be a great discount. I assume that the price has fallen for three reasons. Firstly the fall in the price of uranium for $145 to $75. Secondly the stock got ahead of itself in last years bull market and thirdly the US recession and recent sell off of the market in general. Could someone tell me please if there are any other reasons for such a harsh sell off. All the 'experts' seem to have a buy rating on this stock. I am in the stock for at least 2 - 3 years. Thanks...
