 Four out of every five stocks in the S&P were climbing today, with homebuilders, real estate owners, and other stocks that tend to benefit the most from easier interest rates leading the way. But slumping tech stocks, including influential companies NVIDIA and Apple, mask the underlying strength. That dragged the S&P down about 1%, 45 points lower at this hour, while the Nasdaq was down 2%. It's off 328 right now.
