Stocks could soar 10% by mid-2023, but investors should expect a decade of flat markets after that, major investment bank says

After a brutal 2022, the stock market has managed to eke out minor gains over the first few trading days of this year, and the streak could continue over the next six months, according to Barry Bannister, chief equity strategist of investment bank Stifel.

“There is a window for a first-half 2023 rally,” Bannister wrote in a Monday research note, arguing the S&P 500 index could jump roughly 10% to 4300 by mid-June.
