US stocks rise as tech sector leads rally amid high hopes for Nvidia earnings

• Stocks rose Tuesday, with tech shares continuing their rebound ahead of key earnings.
• Nvidia and Snowflake are set to report second-quarter results on Wednesday.

US stocks were mostly higher Tuesday, extending gains sparked by expectations around upcoming earnings reports and the Federal Reserve's Jackson Hole meeting.

Following a three week sell-off, markets are rising ahead of financial results from key tech players in the artificial intelligence sector. Alongside Snowflake, chip giant Nvidia is set to release its earnings on Wednesday, fueling hopes for a revived rally.

On Friday, Fed Chairman Jerome Powell is scheduled to give his speech at the central bank summit in Wyoming, providing guidance for the Fed's future monetary policy and the central bank's outlook for the economy.

While the surge in the 10-year Treasury yield has made some analysts expect a dovish approach on Friday, the Fed has yet to achieve its 2% inflation rate, which means it could stay hawkish and signal more tightening of monetary policy still to come.
