What they’re saying

“To wrap up the month of February, we were reminded there are still some cracks out there.”

“Adding to the day's weakness was the hotter inflation data, potentially pushing back on the idea of a dovish Fed later this year.”

— Ryan Detrick, Chief market strategist

“It's been a rough go in February, but corporate America is looking at over a 14% gain in earnings in the fourth quarter. The reality is that earnings drive long-term stock gains and this was a very impressive earnings season.”

— Ryan Detrick, Chief market strategist

“This is a classic risk-off environment where the pure defensive areas are finding some strength while the market is turning its head on some of the more cyclical growth areas that are clearly lagging.”

— Ryan Detrick, Chief market strategist
