Do you understand what immunotherapy is ? And how companies are investing on it ? It's a hot area of research for different kinds of cancer. There are many developmental biotech companies working hard on it. Of course they don't have any income , they'll be at loss. If so almost all of these companies should be zero ? Why do they trade at higher price even if they're at loss ? It's their pipeline and future potential .

Go google TBRA (Tobira pharmaceutical) - was trading at $4 then big pharma bought it for $32 , overnight it went up +700% . Why ? That's something for you to research on . Yeah it didn't have any income, only loss ..

Few people posted their opinion here and you're coming out with your stupid post "kinna lai kar garyo sajha ko sathi haru le " ? Sajha is not the place you should seek investment advice . If you're looking for advice from Sajha then you shouldn't be investing with your real money, you should do paper trading .
