U.S. Treasury Secretary Scott Bessent is "pulling levers" in the bond market by doubling liquidity in longer-duration bonds, says Charles Schwab's Collin Martin. He considers the move a short-term fix to push back bond volatility. Collin adds that Fed Chair Kevin Warsh "will keep us guessing" on the direction of interest rates. Rachel Dashiell turns to equities by focusing on levels to watch in the S&P 500 (SPX) as breadth "slightly weakens." She also turns to the volatile price action in the Russell 1000.
