BioVie (BIVI) stock has shown extreme volatility recently, surging 98.7% to $4.67 in pre-market trading on October 21, 2024, but later dropping 56% to $1.24 due to a $3 million secondary offering priced at $1.53 per share. Bulls may argue that the stock's potential lies in its innovative treatments and speculative appeal, but the dilution and sharp price swings highlight significant risks.
