Viking Therapeutics is trading 4.09% higher at $33.11, alongside gains in major U.S. indexes. - The Nasdaq Composite is up 1.05%, while the S&P 500 has gained 0.60%, providing a supportive broader-market backdrop. - No new company-specific announcement explaining the September 30 move surfaced in available results. - Recently closed stock and convertible-note offerings raised approximately $575 million gross; that prior event does not establish the reason for today’s gain.
