SalesforceCRM.N added 1.1% after the cloud-based software provider announced an expanded AI partnership with Google Cloud. By Shubham Batra and Shristi Achar A June 7 (Reuters) - The S&P 500 and Nasdaq were set to open marginally higher on Wednesday as investors refrained from making big bets ahead of inflation data and the Federal Reserve's policy meeting next week. Wall Street's main indexes ended higher on Tuesday, with S&P 500 .SPX up almost 20% from its October 2022 lows, underpinned by rising expectations that the Fed will hold interest rates steady at its policy meeting on June 13-14.
