Stock gains to survive a market correction if rate cuts are delayed, one economist says

The latest stock gains will hold until the end of the year and survive a mid-year market correction, if central banks implement interest rate cuts later than investors have currently priced in, one economist says.

"But then I think by the end of the year, we're
