Analysts are predicting significant gains for the S&P 500 index in the near future. Capital Economics forecasts the S&P 500 could soar to 6,500 next year, contingent on sustained AI hype and a fall in Treasury yields. Wells Fargo projects the index will reach 5,700 in a postelection rally. Meanwhile, Fundstrat's Tom Lee expects the S&P 500 to rise 4% to a record 5,500 by the end of this month, in just three weeks' time.
