Theriva Biologics Inc (TOVX) saw a significant price increase of 18.98% in pre-market trading, as the stock crossed above its 5-day SMA.
This surge comes amid broader market weakness, with the Nasdaq-100 down 0.46% and the S&P 500 down 0.09%. The stock's resilience suggests sector rotation as investors shift focus to biotech companies.
The movement indicates a potential shift in investor sentiment towards Theriva Biologics, highlighting its strong position in the current market environment.
