US stocks rise after positive GDP revision and ahead of speech from Fed Chairman Jerome Powell

• US stocks were up on Wednesday as investors await a speech from Fed Chairman Jerome Powell.
• He is expected to strike a hawkish tone as the Fed continues its fight against inflation.
• Third-quarter GDP growth was revised upwards to 2.9% from 2.6%, while ADP payroll data missed estimates.

US stocks were up in early Wednesday trades as investors await a speech from Federal Reserve Chairman Jerome Powell later this afternoon.

He is expected to strike a hawkish tone as the Fed continues its fight against inflation, though the central bank is widely seen slowing down its rate-hike trajectory to 50 basis points from 75 basis points at its upcoming FOMC meeting in mid-December.

Economic data was mixed on Wednesday, with third-quarter GDP growth revised upwards to 2.9% from 2.6%. Meanwhile, the November payroll report from ADP showed private companies adding 127,000 jobs, well below estimates for 190,000 jobs. The Labor Department's November jobs report will be released this Friday.
