Citigroup strategists predict that the US bull-market rally in stocks is set to end. The bank has maintained its prediction of S&P 500 Index tumbling to 4,000 by year-end, with a new target of 4,400 by mid-2024. Citigroup has highlighted a looming US recession and apparent wariness among investors surrounding the S&P 500’s breakout. Although equities have been on the rise, Citigroup strategists are not convinced of the rally's sustainability, with Morgan Stanley and JPMorgan Chase also continuing their downbeat forecasts. The S&P 500 fell last Friday, its first decline in seven sessions.
