The Treasury selloff pushes the 10-year yields up to 1.254%, the highest it has been since early March, while the 30-year is back to year-ago levels. Markets get a boost from advancing stimulus talks and declining Covid-19 new cases. Spartan’s Peter Cardillo tells WSJ investors could be tempted to reduce their exposure to stocks and move to bonds if yields get high enough. “If we saw the 10-year approach the 1.5% level, that (could send) stocks in a corrective” stage, he says. “With stocks high as yields move higher they begin to narrow the gap between yields and dividends.” (paulo.trevisani@wsj.com; @ptrevisani)
