US stocks were mixed on Wednesday, seesawing the day after a steep sell-off fueled by worries about economic growth.

In an up-and-down trading session on Wednesday, stocks appeared to turn positive after fresh data showed further signs of the labor market cooling, prompting bond yields to fall and investors to ramp up their hopes for more extensive interest rate cuts in 2024.

After the data, markets moved to price in a nearly 50% chance the Federal Reserve slashes interest rates by 50 basis points by the end of its September meeting, up from a 38% chance the day prior, per the CME FedWatch Tool.

The two-year Treasury yield dropped nearly 12 basis points to about 3.76%, its lowest level of 2024 as investors await a highly anticipated August jobs report due out Friday morning..
