It has been roller-coaster ride for Argos Therapeutics (ARGS) this year. Year-to-date, the stock is still up more than 90%. But it is well off its highs reached back in April. ARGS had hit a high of $13.94 before seeing a sharp pullback. The pullback though has created an opportunity as based on my fair value of $9.30 per share for ARGS, the current price level offers tremendous upside.
