IBB [-0.6%]
iShares Biotechnology ETF
The iShares Biotechnology ETF (IBB) has declined by 0.6% during Tuesday's trading session. Significant contributors to this downturn include Sarepta Therapeutics Inc (SRPT), which dropped sharply following the failure of its ESSENCE study despite better-than-expected revenue figures. Other notable declines came from Regeneron Pharmaceuticals (REGN), Moderna (MRNA), Alnylam Pharmaceuticals (ALNY), and Myriad Genetics (MYGN), with the latter reporting a net loss increase and decreased revenue year-over-year, although it surpassed analyst estimates. Additionally, recent macroeconomic reports, including the JOLTs Job Openings and Job Quits data, have influenced market volatility, with IBB typically reacting strongly to labor market indicators. The Russell 2000 Index has also seen a significant decline, reflecting broader market sentiment that may be affecting IBB's performance.
