So ture! BTW, DNDN may present some entry possibilty soon. But never, never, ever hold one bio for more than 5% of your total position, even it is a "sure thing".

5% too low, if it's sure thing,why not put 15-20%? Biotech is not as bad as people saying, more research and play in the right way that's fine, much better then 2x 3x ETF. |
