falling yields & biopharma rotation
Stock markets went up slightly because government bond rates dropped, making stocks look more attractive. Big healthcare companies like Merck and Moderna also did very well, drawing money into the medical sector.
What changed
A decline in Treasury yields supported broader equities, alongside strong individual performances in the biopharma sector.
Who wins / who loses
Growth stocks and biopharma leaders benefit from falling yields, while fixed-income investments lose some relative appeal.
