Actually there are only two Biostocks in all of the ASX that are worth a long term punt: CSL and (possibly) Cochlear.
All the rests are playthings of unscrupulous pump and dunp hustlers.
Suggest any more candidates ?
As for the common cold: Biota itslef made a press release some years ago that a cure for the common cold was impractical as it was a benign condition and curing it had insurmountable technical issues. This I believe.
