The Market Has Been Fabulous, Maybe Excessively So

September is typically a dicey month for the stock market.In many years, so are the weeks before a contentious election.But the returns that millions of investors have been seeing lately have been wonderful — far better than Wall Street projected at the end of last year.The S&P 500 is already 20 percent higher than the Wall Street consensus for all of 2024.
