A 25 bps interest rate is baked into markets, says Jeff Mortimer, the question will be how Wall Street prices a tentative rate hiking cycle pending on how hawkish Fed Chair Kevin Warsh is on Wednesday's decision. He thinks one or two hikes is something stocks can handle, but anything more than that will lead to a stumble in equities and the greater U.S. economy. However, Jeff makes the case the stock market remains in the middle stages of a bull run, though he argues investors in the Mag 7 should diversify.
