Charles Schwab's Nate Peterson takes a look back at last week's price action to explain the moves we're seeing this week. He attributes the weakness to a hawkish interest rate cut from the Fed, a change in A.I. spending perspective seen in Meta Platforms (META), and selling reaction to Palantir's (PLTR) "stellar" earnings indicating a change in psyche for markets. Nate adds that the massive run higher in A.I. stocks only add to upside pressure.
