My broker is telling me to sell if it hits $10 before the FDA approval. I told him I may sell some but no more. Even then if RIGS is announced I will be leaving money on the table. I got in on DNDN for $13 after FDA approval and sold it at $30 and it kept running to $53. I don't want to repeat that same mistake with NAVB especially when you consider NAVB's drugs sales potential combined is five times more than DNDN's drug. All imo of course.
