Treasurys rally, sending yields down, with the 10-year at 0.85%, down from 0.88% on Wednesday, as risk-off mood trumps advances in the quest for a Covid-19 vaccine. Adding to investors’ worries, weekly jobless claims come in at 742K, worse than the 710K consensus in a WSJ survey, in a potential sign of the damage fresh lockdowns may cause. “Investors are likely to stay defensive as mounting risk of Covid-19 may lead to further shutdowns overshadowing the vaccine hope rally,” Spartan’s Peter Cardillo says.
