Bank of America Corp. strategists, led by Michael Hartnett, have advised investors to sell into rallies in U.S. stocks and the dollar, citing a lack of conditions for sustained gains. Hartnett emphasized a cautious approach, recommending selling U.S. stock rallies while buying the dip in other assets. The strategists suggest that despite intermittent rallies, the current market environment does not support prolonged upward momentum in U.S. equities and the dollar.
